When designing a torsionally elastic clutch, the maximum drive torque is one of the most crucial features. It defines the maximum power which can and shall be transmitted during operation. Consequently, a torque measurement is recommended, especially in case of a clutch malfunction. This helps to identify the maximum torque and design the spare parts according to the requirements of your operation.
Stiffness of the material is another crucial feature of a clutch and determines the clutch’s resistance against deformation. It depends not only on the material itself, but also on the shape and size of the cross-sectional area designed to absorb the occurring force.
Vibrations in a powertrain occur regularly, but are somewhat of a challenge. They lead to defects which are detected fairly late because their destructive force developes slowly over time. Off-Highway Powertrain Services recommends a vibration measurement on your powertrain or motor to get to the bottom of this problem and try to eliminate it as much as possible. During operation, periodical vibrations may also occur, becoming stronger over time and causing a kind of cascading “build-up”. This happens especially in diesel motors due to the stroke movement of the cylinder which transmits power to the crankshaft irregularly, causing natural vibrations.
This presents a challenge for the clutch because it has to dampen and absorb those vibrations. The damping characteristics of a clutch depends essentially on the material it is made of.
