During the design two cases are considered: prescribed output loading and constant input torque.
Similarly, the output speed of a gear reducer is less than the input speed, but the output torque is greater than the input torque.
In a companion paper (Input torque balancing using a cam-based centrifugal pendulum: design procedure and example, J. Sound Vib)., the cam-based centrifugal pendulum (CBCP) was introduced as a simple, cam-based, input torque balancing mechanism.
Input torque balancing is a well-known way to reduce drive speed fluctuations in high-speed machinery and combustion engines.
The robustness with respect to unknown input (torque disturbance) and the sensitivity with respect to drift faults are experimented.
The basic approach is to modulate the input torque such that it compensates the periodic change in mesh stiffness.
Based upon two sliding mode observation vectors, the input torque is designed to achieve the control goal.
The impacts of the input torque, surface roughness and lubricant temperature on the gear contact fatigue under the tribo-dynamic condition are also investigated.
In order to correct this imbalance, a method of producing an assisting torque by cross-referencing the opposite input torque was developed.
Furthermore, our study shows that the combustion rate improvement, input torque, and components durability can be improved by tuning valve clearance or adjustment the cam profile.
Furthermore, in a design example, the CBCP was applied to balance the input torque of a high-speed cam-follower mechanism, driving the sley of a weaving loom.
