1 INTRODUCTION
The SRP planetary gearbox will give you complete satisfaction if all of the following mounting, operating &
maintenance instructions are respected.
1.1 Warnings
WARNING! HANDLING OPERATIONS.
The SRP unit can be handled by the main housing, the bevel box shafts, the fixing flange
holes or, with lifting rings by the output flange tapped holes.
WARNING! LUBRICATION REQUIREMENTS.
SRP units are delivered with oil and lubricated for a life time of 10000 hours.
Refer to lubrication chapter in this manual to respect all lubrication requirements.
Any damage due to an incorrect lubrication will void the warranty.
1.2 Gearbox identification
Each unit can be identified through its identification plate and the serial number indicated on it. The serial
number must be given for any correspondence on a particular unit.
1.3 Long term storage
Each gearbox is delivered wrapped and greased for 1 month anti-corrosion protection. Gearboxes which
are not installed shortly after receipt should be stored in a dry atmosphere with temperature between 0°C
& 40°C. The unit must be filled completely with oil for storage.

3.3 Oil draining
SRP units are delivered with oil and lubricated for a life time of 10000 hours.
In order to remove all residual particles in oil, do not hesitate to:
- Run the unit before draining in order to reduce the viscosity of the old lubricant
- “Wash” the unit with fresh oil before refilling.
1. Unscrew the fill-in plug situated at the top of the unit to allow air entering the gearbox.
2. Unscrew the lowest plugs and wait until no more oil flows out from the unit.
NOTE:
Drained oil is a special industrial waste and should be handled according to current laws.

4 MOTOR INSTALLATION
4.1 MF-type motor flange mounting (for right angle configurations SRP.R and cylindrical shafts)
Respect the following instructions to install the motor flange.
1. Clean the mounting surfaces to be fitted together i.e.: coupling, pilot diameter of the motor, the flange
and the motor shaft.
2. Mount the coupling (with or without shaft adapter) onto the bevel box shaft.
WARNING!
When the coupling bore is bigger than the diameters of the motor shaft or bevel box shaft, a
shaft adapter is supplied with the coupling. The groove of this adapter must be aligned with
the coupling split bore.
3. Place the coupling with respect of the distance A (see picture & table).
4. Tighten the screw of the coupling on the bevel box side (adequate tightening torque: see table 1).
5. Mount the MF flange and tighten its 4 fixing screws (“screws MF Bevel box & torque” in table 1).
6. Carefully slide the motor shaft into the coupling bore (with the shaft adapter if supplied) until the motor
face sits in the pilot diameter bore of the MF flange.
7. Tighten the motor screws one after the other in several passes (see tightening torque in table 2).
8. Tighten the other screw of the coupling (at the adequate tightening torque: see table 1).

4.2 MF-type motor flange mounting (for right angle configurations SRP.R and taper shafts)
Respect the following instructions to install the motor flange.
1. Clean the mounting surfaces to be fitted together i.e.: coupling, pilot diameter of the motor, the flange
and the motor shaft.
2. Mount the MF flange onto the gearbox and tighten its 4 fixing screws (“screws MF Bevel box &
torque” in table 1).
3. Remove the taper hub part from the coupling.
4. Place the taper hub onto the motor shaft. Tighten the motor shaft nut.
5. Install the coupling on the taper hub part. Tighten the fixing screws (size M6, tightening torque
15Nm).
6. Carefully slide the motor together with the coupling onto the bevel box shaft until the motor face sits in
the pilot diameter bore of the MF flange.
7. Tighten the motor screws one after the other in several passes (see tightening torque in table 2)
8. Tighten the other screw of the coupling (at the adequate tightening torque: see table 1).

4.3 IF-type motor flange mounting (for in-line configurations SRP.M)
Respect the following instructions to install the motor flange.
1. Clean the mounting surfaces to be fitted together. Pay special attention to the motor shaft and the
gearbox input split bore.
2. Rotate the clamping hub in order to bring the screws in front of their radial holes. Rotate the input
split-bore of the gearbox in order to align the split bore groove with the clamping hub groove as
shown in the sketch below.
a. In case of a cylindrical shaft
When the clamping hub bore is bigger than the
diameter of the motor shaft, a shaft adapter is
supplied with the unit. The groove of this
adapter must be aligned with the split bore.
b. In case of a taper shaft
A shaft adapter (taper -> cylindrical) is
supplied with the unit. Tighten the motor shaft
nut after installing the adapter.

3. Check that the motor / gearbox interface dimensions are correct. Avoid the following improper
assemblies:
Motor shaft should
not reach the end of
the input bore.
Motor shoulder must
not reach the
clamping hub.
Motor radius must not
reach the clamping
hub.
Motor shaft must be
locked on the full
clamping hub width.
4. Make sure that the clamping screws of the input split-bore are not tight.
5. For size 6 only, install the 2 keys into the appropriate grooves to prevent the input bore from moving
down while mounting the motor. See pictures:
6. Lower the motor vertically onto the gearbox (and for size 6: maintain the 2 additional keys in
position) and fix it by tightening the 4 screws of the flange at the adequate tightening torque (table
below):
WARNING!
The motor must be mounted without applying any stress on the input shaft. The motor
centering is done by the gearbox input shaft. That is why it is absolutely necessary to mount
the motor vertically. A wrong mounting can lead to bad running conditions damageable for
the gearbox.
7. Gradually tighten the 2 clamping hub screws by half rotations until the tightening torque shown in the
table below is reached.

5 OUTPUT PINION (OP) MOUNTING
WARNING!
The rack and the output gears must be lubricated before running the SRP.
In case of fixing an output pinion (OP) to the SRP output flange,
we recommend respecting the following procedure:
1. Place the output pinion on the output flange pilot diameter.
2. Insert the fixing screws without tightening them.
3. Control the pinion run out by means of pins. The admissible
run out values are written in the following table. For other
pinion types, please consult us.
4. Adjust the pinion centering if necessary.
5. Tighten the fixing screws at the adequate tightening torque.

7 MOUNTING OF THE SRP WITH OUTPUT PINION ON THE MACHINE
WARNING! HANDLING OPERATIONS.
The SRP unit can be handled by the main housing, the bevel box shafts, or, with lifting
rings by the output flange tapped holes.
7.1 Rack mounting tolerance
Parallelism between the rack reference surface and the linear guide
The SRP requires that the rack has been installed on the machine following the rack manufacturer
mounting procedure and respects the tolerances shown below:
We advice to measure the parallelism error values on 3 points for each segment of rack, as shown on the
drawing below. This rack topography will be used for proper tooth meshing validation and preload
setting (see next chapters).
In order to control the pitch error, we also recommend doing 3 measurements at each connection of 2
rack segments, as shown on the sketch below.
The variation between the 3 comparators at each connection must not exceed:
- 0.015 mm for a rack module 3,
- 0.020mm for a rack module > 3.
