Stiffness describes the ability of a body to resist elastic deformation. The transmission of power would not be possible without stiffness. However, there are events which should not be transmitted, such as torque peaks and shock loads. In order for a system to withstand such loads, it is damped. Engineers are confronted with the challenge to tune stiffness and damping in a vibratory system in such a way that reliable operation, essentially free of load peaks, is ensured.   

Motor shaft couplings have to strike a delicate balance when it comes to stiffness. On the one hand, they have to be rigid enough to transmit torque efficiently. On the other, they have to be flexible enough to handle any misalignment between the motor and the drive shaft. Our latest coupling design can help you strike that balance.

The big gearboxes that drive cable drums do not come cheap. Yet engineers often make a design mistake that can shorten the gearbox’s working life. This mistake involves the use of a rigid, direct coupling between the gearbox output shaft and the cable drum.
