2. Installation
(1) Ambient conditions
Install the reducer without a otor in an a bient te perature range fro -10 to 50°C and the reducer with a otor in an a bient te perature
range fro -10 to 40°C in a location that is well-ventilated, less dusty, and low in hu idity. Do not use the reducer in locations with corrosive
liquids or gases, or in fla able or explosive locations. If the reducer is to be used outdoors, furnish a cover or si ilar protection to avoid direct
exposure to rain.
(2) Transport
CAUTION
 Use caution when transporting the reducer as it is dangerous if it drops or falls over. If the HDR/HDM Series has lifting rings, always use those
lifting rings. However, after the reducer is installed in the achinery, do not hoist the achinery itself with the lifting rings. Before hoisting the
reducer, check the HDR/HDM Series weight on the na eplate, packaging, external diagra , or catalog, and do not suspend a reducer that
exceeds the weight rating of the lifting rings. Otherwise there is a risk of da aging the lifting rings, injury fro the reducer falling over, and
da age to equip ent.
Be sure to use the eye-nut on the top surface of the housing (fastened with a hex bolt) when transporting the reducer. Never hook wires or slings
to the input/output shafts. Doing so ay ake the shaft eccentric or cause other proble s which will shorten the life of the reducer or cause it to
fail.

(4) Installation
DANGER
When hoisting the reducer to transport it, do not enter the area underneath it. Otherwise there is a risk of accidents due to the reducer falling.
CAUTION
・ Do not place obstructions around the HDR/HDM Series that will interfere with ventilation. This will hinder cooling and ay result in burns or a
fire due to abnor al heating.
・ Do not get on the HDR/HDM Series or hang fro it under any circu stances. Otherwise there is a risk of injury.
・ Do not touch the keyways on the shafts of the HDR/HDM Series with bare hands. Otherwise there is a risk of injury.
・ For equip ent that is averse to greasiness such as food achinery, take precautions for an accidental oil leak due to a breakdown or the
service life and install da age prevention equip ent such as an oil pan. Otherwise there is a risk the reducer ay beco e faulty due to an oil
leak.
- Mounting to the driven shaft (hollow output shaft type) -
・ Check the direction of rotation before connecting the reducer to the driven achine. There is a risk of injury and da age to equip ent by
istaking the direction of rotation.
・ Lightly tap the end of the output shaft with a plastic ha er to insert it. Do not tap the casing or the oil seal.
・ Always secure the shaft to the driven shaft to prevent the fro co ing apart.
(Solid output shaft type)
・ Install on a s ooth flat installation surface that can easily withstand the weight of the equip ent. The installation angle should be within ±1°.
・ Use bolts co pliant to JIS strength class 10.9T for installation.

Note) Failure to install the reducer correctly ay result in vibration, noise, and reduced life.
Note) If the reducer is installed at an angle that exceeds ±1°, the oil level and the location of the oil gauge and each plug will no longer apply.
(Hollow output shaft type)
The nor al practice is to ount the hollow output shaft type reducer to the driven achine, and then fix it in place with a torque ar or tie rod to keep
it fro turning by reaction force.
(1) Mounting to the driven shaft
The shaft to which the reducer is to be ounted should be g7. The hollow shaft bore is finished to H8.

- Mount as outlined here.
Step Mounting procedures
1
Install the key on the driven shaft.
Note) Use a bar key. Do not use a tapered or gib headed key. Doing so ay ake the output shaft eccentric or cause other proble s which will shorten the life of
the reducer or cause it to fail.
2
Hoist the reducer using the eye-nut on the top of the housing and slowly insert it onto the driven shaft.
Align the phase of the key before inserting it.
Note) If the shaft fits too tightly, help the hollow output shaft slide s oothly by lightly tapping the end with a plastic ha er. (Apply grease or olybdenu
disulfide to the driven shaft.)
Be careful not to da age the oil seal.
3
Use an end plate to fix the reducer and driven shaft in the thrust direction. The end plate can be fixed on the driven shaft with a stop ring in
the stop ring groove of the hollow output shaft, or by fixing it to the end of the shaft, but taking disasse bly into consideration, we
reco end the ethod securing the stop ring and end plate.
Place a stop ring in the stop ring groove on the hollow output shaft and ount the end plate on the reducer output shaft side of the stop
ring. Then fix the end plate to the driven shaft with hex bolts.

● If the driven shaft is vertical and points down
Use the stop ring and bolts as shown in the figure above to prevent the reducer fro falling off, and take all safety precautions necessary.
Note) Always apply Loctite or si ilar locking agent to the bolts.
● If the driven shaft faces up
Machine a shoulder on the driven shaft to prevent ove ent in the thrust direction.
(2) Securing
(Torque ar )
- Secure as outlined here.
Step Mounting procedures
1
Mount the torque ar to the reducer. Select the proper ounting bolts by referring to the reco ended installation bolts for
the S type.
Note) The torque ar is subject to reaction force fro the reducer. Use a torque ar robust enough by considering the bending o ent under
axi u torque, such as when starting and stopping.
2
Mount the reducer on the driven shaft, then ount the torque ar to the fra e of the achine. When ounting the torque
ar to the achine fra e, leave clearance between the reducer and driven shaft to avoid causing eccentric loads.
Note) If the torque ar is fixed to the achine fra e, the reducer output shaft bearings and the driven shaft could break due to excessive radial
and thrust loads, so always provide the torque ar a degree of freedo .
Note) To reduce shock, use rubber bushings between the torque ar and ounting bolts on the achine fra e side.
(Tie rod)
・ Please consult with Tsubaki E&M.
(Flange and base mounting notes)
・ Install on a s ooth flat installation surface that can easily withstand the weight of the equip ent.
・ Select ounting bolts reco ended for the solid output shaft type reducer.
・ Mount as outlined here.
Step Mounting procedures
1 Free the driven shaft in the thrust direction.
2 Insert the reducer into the driven shaft, then ount to the flange surface and base surface.
3 Fix the reducer in the thrust direction of the driven shaft.
4 Fix the driven shaft in the thrust direction.
Note) If the reducer is ounted on its flange surface and base surface after it is fixed to the driven shaft in the thrust direction, the bearings on the reducer or the driven shaft
will be subject to thrust force which could result in reduced life or achine failure.
(5) Connection (input shaft of the HDR Series, solid output shaft type)
CAUTION
-
Connecting the motor and driven machine (input shaft of the HDR Series, solid output shaft type)
-
・ When connecting the HDR/HDM Series to a otor and the driven achine, pay careful attention to centering, belt tension, and the parallelis of
the pulleys. When directly connected, pay careful attention to the accuracy of the direct connection. When belt driven, correctly adjust the belt
tension. Before operation, ensure that the tie bolts for the pulleys and couplings have been fully tightened. Otherwise there is a risk of injury due to
flying debris and da age to equip ent.
・ Install a cover so that rotating co ponents will not be touched. Otherwise there is a risk of injury.
・ When the HDR/HDM Series will rotate independently, re ove the key that is te porarily installed to the output shaft. Otherwise there is a risk of
injury.

- The input and output shaft dia eters are finished to h7.
- When using a coupling or si ilar ele ent to connect the input and output shaft to another shaft, align and fix it in place so that the center of the
ating shaft is aligned accurately. Any eccentricity in the shafts will shorten the life of the gears, bearings, and shaft, resulting in vibration and noise.
Center align ent is also i portant when using flexible couplings to prevent fro trans itting radial loads fro the coupling. We reco end our
Flexible Couplings.
- When ounting couplings, pulleys, and sprockets on the shaft, be careful not to bend the shaft and not to scratch the bearings and oil seals.
(6) Wiring (applies to motor handling code S and SB for the HDM Series)
- Refer to the separate instruction anual for details on otor wiring.
(7) Removal (hollow output shaft type)
- When re oving the reducer fro the driven shaft, supply your own jack bolt and stopper, as illustrated in the figures below, with an end/draw plate
(explained earlier) and a stop ring. The driven shaft length is the reco ended driven shaft length explained earlier.
- Re ove as outlined here.
Step Mounting procedures
1 Loosen the hex bolt used to fix the end plate, and re ove the end plate.
2 Mount the end/draw plate and stopper on the driven shaft side.
3 Insert the jack bolt in the tap on the draw plate and pull the reducer fro the driven shaft.

3. Lubrication
(1) Introduction
- The HDR/HDM Series are both filled with lubrication oil (Shell O ala S2G150) when shipped fro the factory, and they can be used without further
lubrication.
However, you should still check the oil level in the oil gauge after co pleting the installation. If the oil level does not appear in the oil gauge, supply
oil until it is visible.
- Even when the oil level falls below the oil gauge when changing the oil or when the oil has decreased due to whatever conditions, the re aining oil
will occasionally appear to be re aining at the lower end of the oil gauge due to surface tension. Therefore, in anaging the oil level, please check
that the oil level is aintained in the iddle of the oil gauge.
Note) For a ounting direction other than that ordered, the reducer will have a different a ount of lubrication oil, and the oil gauge and plugs will also be in different positions.
Note) Contact us if the a bient te perature is less than 0°C or higher than 50°C.
Note) For input speeds slower than 500 r/ in, switch to an oil reco ended in the following table.
- After co pleting the installation, be sure to replace the plug on the oil filling port with the supplied pressure vent.
(2) Oil replacement
- First change: 500 hours after starting operation. Subsequent changes: 2500 hours or 6 onths, whichever co es first.
Step Replace ent procedures
1
Perfor the oil replace ent when the achine is stopped.
Note) The housing and oil level are very hot i ediately after stopping. Wait for the housing surface to cool before replacing the oil.
2 Have a drip pan ready and place it under the reducer's drain plug.
3
Re ove the drain plug with an Allen key wrench to drain the oil. Re ove the pressure vent to allow the oil to drain quickly.
Note) Do not loosen the drain plug all at once. Otherwise, oil ay splash out.
4
Apply sealant to the drain plug and fully tighten it in place.
Note) Shin-Etsu silicone one-co ponent RTV rubber or an equivalent product is reco ended for the sealant.
5
Check the ounting direction exa ples and refer to the following tables to deter ine the proper oil volu e. Pour the reco ended oil into the
oil inlet until visible in the oil gauge.
Note) If the reducer is ounted at a sharper angle than shown in the ounting exa ples, fill with a little ore oil than indicated below.
6 After filling, attach the pressure vent.

4. Operation
DANGER
- During operation, do not get near or touch any rotating bodies (shafts or other parts). Otherwise there is a risk of being caught in those parts
resulting in injury.
CAUTION
・ For a specification with a fan cover, do not insert your hand in the fan cover. Otherwise there is a risk of being caught in those parts resulting in
injury.
・ During operation, the HDR/HDM Series reaches high te peratures. Use caution not to touch the reducer with your hands or body. Otherwise there
is a risk of burns.
・ When a proble occurs, i ediately stop operation. Otherwise there is a risk of injury.
・ Do not use the reducer with a load that exceeds the rated load. Otherwise there is a risk of injury and da age to equip ent.
・ Do not loosen the oil plugs during operation. Otherwise lubrication oil ay spray out resulting in burns.
・ When running the reducer in reverse, first stop it, and then run it in reverse. Forward and reverse operation by plucking ay da age the
HRD/HDM Series and the driven achine.
(1) Inspecting prior to use
Upon co pleting the installation, check the following prior to operation:
・ Is the direction of rotation is correct?
・ Is the connection to the driven shaft secure?
・ Are there any loose ountings or bolts?
Make sure the equip ent incorporates failsafe easures to prevent accidents fro occurring due to the use of the reducer, or in the event the
reducer alfunctions.
(2) Trial run
Before running in production, run the reducer without loading. Verify the rotating direction, and check for abnor alities such as vibration, noise,
and heat. Gradually increase the load.
(3) Production run
Verify the following after starting production:
・ There is no abnor al vibration, noise, heat, etc.

7
・ The reducer is not subject to shock or overloads.
Note) Loading the reducer above the allowable capacity can shorten the life of the gears, resulting in da age to the reducer. Do not load the reducer above its allowable

(Daily inspection and aintenance)
・ Change the lubrication oil and grease according to the instruction anual. Always use the type of oil reco ended by the anufacturer.
Otherwise there is a risk of da age to equip ent.
・ The surface of the HDR/HDM Series reaches high te peratures, so do not touch it bare hands. Otherwise there is a risk of burns.
・ Do not change the lubrication oil or grease during operation or i ediately after stopping. Otherwise there is a risk of burns.
・ Diagnose proble s that occur based on the instruction anual. Do not operate the reducer until the cause of the proble has been deter ined
and action has been taken.
(1) Maintenance
・ When perfor ing aintenance, wear suitable clothing and use protection including safety glasses, gloves, safety shoes, etc.
・ To prevent secondary accidents, keep the surrounding area safe and tidy.
・ Always turn the power off and wait for the achine to co e to a full stop. Also, use lock-outs to prevent unintentional power supply.
・ The Helical Power Drive reaches extre ely high te peratures during operation. Do not touch with your bare hands.
・ Read and follow labor safety codes and standards.
(2) Maintenance items
Make daily inspections using appropriate easuring instru ents for the following procedures. Take note of operating conditions when
perfor ing aintenance.
Ite Details
Noise Is the noise louder than usual? Are there unusual periodic noises?
Vibration Are there any unusual vibrations?
Te perature rise Is there an unusual increase in te perature?
Lubrication oil leak Is oil leaking fro the oil seal or couplings?
Note) (1) When a proble occurs, i ediately stop operation and perfor a detailed inspection.
(2) If the cause is unclear or repairs are not possible, consult the dealer where the reducer was purchased.
(3) Replacement of the oil seal
The oil seal also has a service life. The service life ay be shorter when used at high te peratures, high rotating speeds, outdoors, or otherwise
harsh conditions. Inspect the oil seal at regular intervals, and replace it i ediately when oil leaks occur. Replace the oil seal with the following
procedure.
Ite Details
