TORQUE-ARM II BELT GUARD
INSTALLATION
Two different belt guards are available for the Torque-Arm
II speed reducer. One belt guard assembly is designed for
mounting in position "B" and the other belt guard assembly is
designed for mounting in position "C" as shown in Figure 14.
It is important that the mounting position of the Torque-Arm II
motor mount be determined prior to purchase of the belt guard
as these two guards do not interchange and will be attached to
the motor mount uprights.
WARNING: To ensure that drive is not unexpectedly
started, turn off and lock out or tag power source before
proceeding. Remove all external loads from drive before
removing or servicing drive or accessories. Failure to
observe these precautions could result in bodily injury.
WARNING: Ensure that all guards are properly installed
before proceeding. Exercise extreme care to avoid
contacting rotating parts. Failure to observe these
precautions could result in bodily injury.
Vertical Installation (Position B):
1.
Move belt guard and hardware from box and verify all parts
are available. The belt guard assembly consists of one
back cover, one front cover, two brackets, and necessary
hardware.
2.
Using the hardware provided, assemble the two brackets
to the back cover as shown in Figure 16. Note that the
brackets are mounted so that the angles of the brackets are
mounted to the inside. Do not fully tighten these bolts.
3.
Position back cover over the motor shaft and reducer input
shaft. The long slot in the back cover fits over the motor
shaft.
4.
Align the back cover assembly to the Torque-Arm II motor
mount and attach using four cap screws, washers, and
nuts. Securely tighten the brackets to the motor mount and
back cover.
5.
Install motor and reducer sheaves. Install belts and adjust
accordingly.
6.
Position and install the front cover onto the back cover.
Note: The front cover is designed with an extended lip
at the top of the cover and installs over the top of the
back cover.
7.
Secure the front cover with four cap screws and washers.
8.
Check machine for proper operation.
