(c–2) How to set a torque arm (1110#-1640#)
Mount a torque arm on the driven machine side of the Drive casing. Use hexagon
socket head bolts for mounting. (See Table 4 for bolt sizes.)
Torque arm anti-rotation stopper should be designed so as to allow movement of the
torque arm to make sure that the contact surface between the Drive and shaft are free
from excess force.
Don't fix the torque arm by anti-rotation bolts.
For such applications as requiring frequent start and stop or frequent reversing of the
rotating direction, insert a rubber bushing between the torque arm and securing bolt (or
spacer) in order to relax impact load.
