Housing torque arm (single arm), alignment

■
Overview
The alignment of the torque arm is defined via the mounting po-
sition of the planetary gear unit/geared motor (page 1/4). De-
pending on the selected mounting position the torque arm can
be mounted in increment t with a horizontal mounting position.
The increment depends on the drilling pattern of the housing
flange.
With vertical mounting position M2 only a restricted alignment
range of the torque arm is possible as a result of the oil expan-
sion tank mounted at 180°. For the vertical mounting position M4
there is no restriction on the alignment.

For size 40 a torque arm with adapted hole pattern is envisaged in the
horizontal mounting position for alignment angles 90° and 270° on account
of the drilling pattern of the housing flange (mounting positions M5 and M6
with possible alignment range 10 ... 350°).
