Dimensional drawings
In the case of shaft-mounted gear units with a torque arm, the connection between the torque arm and foundation must always permit
the gear unit to move in accordance with the bearings of the machine shaft, without constraining forces acting on the gear unit.
Ordering information
When ordering the housing torque arm,
"-Z"
must be added to the article number.
The gear unit is designed as standard for flange mounting or base attachment.
When a single housing torque arm is used, special bearings are required.
This is also necessary when the housing torque arm is not included in the order, but the customer plans to use it.
If a single torque arm is used by the customer, both the minimum dimension c and the use of the exact number of bolts with property
class 10.9 and relevant tightening torque
T
A
must be complied with.
Note:
The torque arm is supplied loose.
The hollow shaft with spline in accordance with DIN 5480 is not possible in combination with torque arm.
In combination with a design in accordance with the ATEX Directive, the torque arm can only be ordered as an oscillation damping
version.
