PMC Precision Plum Coupling

 

The PMC coupling consists of 3 parts for easy shaft installation. Backlash-free transmission is guaranteed under the action of prestress. At the same time, the perfect combination of its good rigidity and optimized damping performance greatly improves the dynamic characteristics of the transmission system. This structure makes the installation extremely convenient and saves installation time.

 

The key element of the PMCJ common plum coupling is the elastomer, which can transmit torque with zero backlash and no vibration. The type of elastomer determines the characteristics of the entire drive system.

The backlash is eliminated by the pre-compression between the elastomer and the shaft sleeve. The Shore hardness of the elastomer is various, and the coupling can achieve ideal torque characteristics by selecting different elastomers.

 

The design structure of PMC enables it to compensate for axial, angular and radial deviations without causing wear and premature aging of the elastomer. Since the elastomer is only subjected to positive pressure, backlash-free movement can still be guaranteed after long-term operation.
