The purpose of the present disclosure is to obtain an elevator traction machine and a brake device thereof, which can reduce collision sound when a brake pad collides with a brake rotating body. The brake pad (24) can be displaced relative to the piston (25) by rotation of the brake disc (20) when the brake disc (20) is displaced into a working position when the brake disc (20) is rotated. In addition, the housing (23) is provided with a first housing-side inclined surface (23a) and a second housing-side inclined surface (23b). In addition, the first housing-side inclined surface (23a) and the second housing-side inclined surface (23b) are inclined with respect to the brake surface (20a) in a direction approaching the brake disc (20) as the distance from the piston (25) increases.

    本公开的目的在于得到电梯曳引机及其制动装置,其能够降低制动片与制动旋转体碰撞时的碰撞声。制动片(24)在当制动盘(20)旋转时移位到工作位置的情况下,能够通过制动盘(20)的旋转而相对于活塞(25)移位。另外,在壳体(23)设置有第一壳体侧倾斜面(23a)和第二壳体侧倾斜面(23b)。另外,第一壳体侧倾斜面(23a)及第二壳体侧倾斜面(23b)向随着远离活塞(25)而接近制动盘(20)的方向相对于制动面(20a)倾斜。
