The invention discloses an elastic friction piece for an elevator and an abrasion loss judging method. The invention discloses the elastic friction piece for the elevator, and the elastic friction piece comprises an elastic body and a plurality of rigid beads. The elastic body has an outer friction surface for contact with a rigid member. The plurality of rigid beads are embedded into the elasticbody. When the elastic friction piece is worn out until the rigid beads are exposed, the rigid member can make contact with and collide with the rigid beads and make contact and collision sound. Whenthe contact and collision sound between the rigid member and the rigid beads is received, elevator maintainers judge that the elastic friction piece is excessively abraded and needs to be replaced. Therefore, whether the elastic friction piece is excessively abraded or not and needs to be replaced can be conveniently judged without disassembling an elevator speed governor. In addition, the runningsafety of an elevator is further improved.
电梯用弹性摩擦件和磨损量判断方法。本发明公开一种电梯用弹性摩擦件,包括弹性本体和多个刚性珠。弹性本体具有用于与一个刚性部件接触的外部摩擦面。所述多个刚性珠嵌入所述弹性本体。当所述弹性摩擦件被磨损到刚性珠外露出时,所述刚性部件会接触和碰撞所述刚性珠并发出接触和碰撞声。当接收到所述刚性部件和所述刚性珠之间的接触和碰撞声时,电梯检修人员判断所述弹性摩擦件磨损过度,需要更换。因此,本发明无需拆卸电梯限速器就能够方便地判断出弹性摩擦件是否磨损过度,需要更换。此外,本发明还提高了电梯运行的安全性。
