Resonant frequencies
Resonance can occur in the speed range of the geared motor depending on the machine to
be driven.
Operation in resonance causes increased noise and vibration levels.
Adherence to the maximum permissible vibration severity is always required.
Operation in the resonant frequency leads to a reduced service life of the geared motor,
irrespective of adherence to the maximum vibration severity.
Continuous operation in the resonant frequency must be avoided.
12.1.9 Thread sizes and tightening torques for fastening bolts
The general tolerance for the tightening torque is 10%. The tightening torque is based on a
friction coe󹪟cient of μ=0.14.
