•
Clamp close to the motor. For maximum performance,
secure pulleys and pinions as close to the motor face as
practical. This effectively reduces the lever arm (and associated
bearing load) for applications with a side load.
•
Don’t over tighten belts. Always read the belt
manufacturer’s guidelines for proper belt tension, but never
exceed the ClearPath-SC specification for maximum side load.
Overly tight belts put undue stress on the motor shaft and
bearing systems that can result in premature bearing and shaft
failure.
•
Avoid using shaft keys when possible. Although
ClearPath-SC includes a keyway feature on the shaft, Teknic
does not generally recommend the use of keys. Keys tend to
cause run-out and backlash errors, particularly in reciprocating,
precision positioning motion applications.
•
Note: Keys should be considered for use in applications where
coupling slip could result in a dangerous or hazardous
condition. Also, key use may be appropriate for unidirectional
applications (where the motor always spins in the same
direction) as these applications are less prone to key-related
lash problems.
•
Avoid direct loads. In general, ClearPath-SC motors are not
designed for connection to direct loads (e.g. direct connection to
a grinding wheel). However, direct connection may make sense
if the load is of low-mass and balanced, as with small mirrors
for laser applications.
