产品描述

梅花垫特性:梅花垫是用联轴器中间起到减震、绝缘、缓冲传递扭矩之作用。

爪型联轴器国内通常称为“梅花型联轴器”。由两个全等铝制或钢制的爪形轴套，在圆周方向上相互错开半个齿距，其间装有一个预应力的渐开线梅花形弹性体，弹性体内的预应力可保证正、反向传动无齿隙，定位。同时，梅花型弹性体可以吸收传动中产生的振动。爪型联轴器中的弹性体可以减震，同时这种扭向刚性联轴器保证的定位。

Characteristics of quincunx cushion: quincunx cushion is used in the middle of the coupling to reduce vibration, insulate, buffer and transmit torque.

Jaw coupling is commonly called "quincunx coupling" in China. Two claw shaped shaft sleeves made of full grade aluminum or steel are staggered for half a tooth pitch in the circumferential direction, and a prestressed involute quincunx elastomer is installed between them. The prestress in the elastomer can ensure that the forward and reverse drive have no backlash and are positioned. At the same time, the quincunx elastomer can absorb the vibration generated in the transmission. The elastomer in the claw type coupling can absorb vibration, and this torsional rigid coupling ensures positioning.
