The invention relates to the technical field of elevator pulleys, and discloses a pulley with wear-resisting and noise-reducing functions for an elevator, the pulley comprises a shell mechanism, and the shell mechanism further comprises an equipment base. Wherein the equipment rotating wheel rotates along the outer wall of the limiting ring frame, the outer walls of the columnar balls rotate along the inner walls of the ball grooves, part of the outer walls of the columnar balls exceed the inner walls of the ball grooves and are in the state shown in the figure 7, when the pulling belt rotates, the columnar balls and the equipment rotating wheel rotate, and power transmission is completed. When the column-type balls generate noise due to friction, the rotating speed of the column-type balls is reduced due to increase of friction force, the noise is reduced while the rotating speed is reduced, the equipment rotating wheel continues to rotate along the outer wall of the limiting ring frame, and the noise is reduced through application of the assembly.
本发明涉及电梯滑轮技术领域,且公开了一种电梯用具有耐磨降噪功能的滑轮,包括外壳机构,所述外壳机构还包括有设备底座,本发明利用摩擦会产生噪音的特点,在设备内部设置有柱型滚珠以及设备转轮,其中设备转轮沿着限制圈架的外壁进行转动,柱型滚珠的外壁沿着滚珠槽的内壁转动,且部分柱型滚珠的外壁超过滚珠槽的内壁,呈现如图7所示的状态,而拉扯皮带在进行转动时,柱型滚珠以及设备转轮将产生转动,完成动力传输,在柱型滚珠因为摩擦出现噪音时,柱型滚珠因为摩擦力的增加导致转速下降,在转速下降的同时噪音减少,而设备转轮将继续沿着限制圈架外壁进行转动,通过上述组件的应用在减少噪音。
