TECHNICAL FIELD

[0001] The utility model belongs to the technical field of elevator accessories, specifically relates to a roller for elevator bearing. BACKGROUND

[0002] The roller for elevator bearing is a crucial component in the elevator system, which bears the weight of the elevator and ensures its smooth operation in the vertical direction. It includes guide shoe rollers, door hanging wheels, and traction wheels.

[0003] The door hanging wheel for elevator bearing is an important part of the elevator door system, responsible for bearing the weight of the elevator door and ensuring its smooth opening and closing. The elevator door rolls on the track through the door hanging wheel, achieving smooth opening and closing, and playing a guiding role.

[0004] The existing roller has the following problems in use:

[0005] The rolling process of the door hanging wheel on the track requires fine adaptation to ensure its stable and smooth operation. If the groove width of the door hanging wheel is designed too large, it will shake significantly when rolling on the track, which not only affects the opening and closing efficiency and stability of the door, but also may cause unnecessary wear to the track. Conversely, if the groove width of the door hanging wheel is too narrow, it will be difficult to effectively stick to the surface of the track, which not only causes the door to be unable to normally hang and move, but also may cause safety hazards due to lack of necessary support.
