How to install the Torque Arm Detent
Ⓐ
part
[1] For normal/reverse rotation operation and unidirectional operation (intermittently)
If mounting has a looseness, impact may be applied to
the torque arm with each startup and defects such
as loosen bolts may occur.
Bolts with sufficient strength shall be used.
(Refer to the right diagram.)
[2] Unidirectional operation (consecutive)
(Refer to ”4-3. Installing/Removing FS/F3S Type Hollow Shaft”.)
In this case, it is necessary to provide sufficient clearance for looseness in both radial and thrust
directions for alignment between the application and detent. (Refer to the diagram below.)
For unidirectional operation (consecutive) which has no frequent start-up torque applied, the torque arm can be
used without a detent. However, it is still necessary to fasten the driven shaft to the hollow shaft.
Fasten the torque arm detent so there is no looseness or wobble. When doing this, center the
detent hole with that of the application to make sure that no radial load (suspension load) is applied
against the driven shaft and hollow shaft of the reducer. (Refer to the diagram below.)
Note)
If mounting without looseness are not allowed for
some reason, rubber bush or other cushion
materials shall be used between the torque arm
and the bolt as a protective measure.
