NOTICE
A coupling with a peripheral speed of up to 30 m/s at the outer diameter must be statically
balanced
2.2
Backstop
ATEX version gearboxes
The drive speed in the table "Drive speed when using backstops" must be reached
in continuous operation.
Starting and stopping operations ≤ 20 starts / stops per hour are permissible.
NOTICE
Replacing the backstop
NOTICE
Damaged or destroyed backstop
A coupling with a peripheral speed of more than 30 m/s requires dynamic balancing.
A flexible coupling is generally used for the gearbox input and output.
If a rigid coupling or other input or output elements are to be used that give rise to additional
radial and / or axial forces (e.g. gear wheels, belt pulleys), this must be contractually agreed.
Please refer to the relevant operating instructions for details of how to use the coupling.
Drive speeds below 1 000 rpm or frequent starting and stopping operations
(≥ 20 starts / stops per hour) will limit service life.
Do not use the same backstop for prolonged periods; replace backstops regularly.
Do not run the motor against the backstop.
Note the directional arrow on the gearbox.

2.2 Backstop
The gearbox can be fitted with a mechanical backstop. The backstop can be fitted either in
the coupling lantern or in the 2nd stage of the bevel helical gearbox. It permits only the
correct direction of rotation during operation. This is indicated by an arrow pointing in the
corresponding direction.
The backstop is fitted with centrifugally operated sprags. When the gearbox is running in the
specified direction, the inner ring and the cage with the sprags also rotate while the outer
ring remains stationary.
Where the backstop is used in the coupling lantern, lifting of the sprags is ensured when the
drive speed is above the speed listed in the table. The backstop is wear-free. It does not
require maintenance.
Table 2- 1 Drive speed when using backstops
112 FXM-61 DX > 750
180/200, 225, 250 FXM-101 DX > 610
When used in the bevel helical gearbox (gearbox intermediate shaft), the backstop operates
at speeds below the lift-off speed of the sprags in a separate oil chamber. The oil must be
changed at the same intervals as the gearbox.

NOTICE
Do not axially distort the motor bearing
Note
The connection between the shafts is rigid and without axial compensation. Therefore we
recommend using motors with a fixed bearing on the drive side for optimum service life.
3.5 Mounting the motor
564, hexagon socket-head screw 561 and screws 505 with
-mounted motor must be sealed across the entire contact surface in
the penetration of a potentially explosive atmosphere.
Be careful not to axially distort the motor shaft when flange-mounting the motor.
Keep the motor shaft completely free from grease in the vicinity of the clamping ring.
In the case of brake motors, release the brake before mounting the motor.
The ventilation-side motor bearing can become distorted when pushing the motor onto the
drive shaft of the input unit.
Above size 100, if the motor is mounted in a vertical position the weight of the rotor shaft
prevents the bearing from being distorted.
When mounting the motor in a horizontal position and in a vertical position up to motor
size 90, please observe steps 6 to 8.
