Technical Field

The utility model relates to the technical field of couplings, in particular to a quincunx elastic coupling.

Background

The output shaft of the motor is provided with a shaft coupling to connect two transmission shafts with concentric axes, and the output shaft of the motor can drive the driven shaft to move only through the shaft coupling. The quincunx spring coupling was first in germany. The elastic coupling has the advantages of compensating relative deviation of two shafts, damping, wear resistance and buffering. The quincunx elastic element is a core component of the quincunx elastic coupling and is mainly a polyurethane elastomer.

The quincunx elastic element is used on the quincunx coupler and plays roles in vibration reduction, buffering and electric insulation. The existing coupler plum elastic element is mainly made of polyurethane rubber, the transmission torque of the existing coupler plum elastic element is small, on the occasion of frequent alternation, due to repeated compression and rebound, heat is easy to generate inside the coupler plum elastic element, the service life of the coupler plum elastic element is influenced due to heat accumulation, the coupler plum elastic element is frequently replaced in the using process, the service life of the coupler plum elastic element is about 20-30 days, and particularly on the occasion of low rotating speed, high torque and frequent alternation, the phenomenon that an elastomer drum ball is broken due to heat accumulation easily occurs, and accidents are caused.
