Elevator element for driving or reversing an elevator suspension means in an elevator system
摘要：
In an elevator element for driving or reversing an elevator suspension device in an elevator system, that interacts with an elevator suspension device, the arithmetic mean of the roughness value of the contact surface measured in the circumferential direction of the elevator element, and the mean roughness value of the contact surface measured in the axial direction of the elevator element, are different. The arithmetic mean roughness value of the contact surface measured in the circumferential direction of the elevator element is less than 1 micrometer.
