Note
In the sense of the current EC Machinery Directive 2006/42/EC, gea
rboxes are components
designed for installation in plants and machines.
Based on the area of validity of the directive, commissioning is prohibited until it has been
absolutely identified that the end product is in conformance with this directive.
The SIMOGEAR gearboxes described in theseoperating instructions have been designed for
stationary use in general engineering applications.
Unless otherwise agreed, the gearboxes have been designed for use in plants and equipment
in industrial environments.
The gearboxes have been built based on state-of-the-art technology and are shipped in an

Resonant frequencies
Resonance can occur in the speed range of the geared motor depending on the machine to
be driven.
Operation in resonancecauses increased noise and vibration levels.
Adherence to the maximum permissible vibration severity is always required.
Operation in the resonant frequency leads to a reduced service life of the geared motor,
irrespective of adherence to themaximum vibration severity.
Continuous operation in the resonant frequency must be avoided.

Figure 2-1 XLplus and VLplus heavy-duty bearing systems
The multi-stage helical gearbox sizes 89-169 can be supplied with an XLplus or VLplus heavy-
duty bearing system.
The parallel-shaft gearbox and the helical gearbox sizes 89-169 can be supplied with a VLplus
heavy-duty bearing system.
With an upstream locating bearing, the bearing system is suitable for high external forces.
The absorbed radial and axial loads are transmittedto the machine via the flange.
The bearings arelubricated independently of the frame size. Initial greasing has already been
carried out. Therelubrication is made with the provided grease nipple.
Options for the VLplus heavy-duty bearing system:
An automatic regreasing device ②can be supplied as option. The automatic regreasing
device ②can be installed at any position and can be used underwater.
A dry-well version with oil sight glass ④or oil sensor ⑤can be supplied as option. The dry-
well version offers increased protection against oil leaks when the output shaft points down.
The flange captures any escaping gear oil for leakages at the oil chamber. The escaping oil is
signaled optically with an oil sight glass ④or electronically by an oil sensor ⑤. If the oil
sensor ⑤is deployed in ATEX version gearboxes, the sensor must be operated with a
disconnector approved for ATEX.
