Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, in particular to a device for synchronously grinding multiple bearing inner rings. Background Art

[0002] The inner ring is a ring-shaped part of the bearing, usually located inside the balls or rollers and mating with the shaft. The inner ring rotates on the shaft by contacting with the rolling elements, bearing and transmitting axial and radial loads. Balls are rolling elements in the bearing, they are usually small spherical objects that can roll between the inner ring and the outer ring. The balls play the role of supporting and transmitting loads in the bearing, reducing friction and sliding. The outer ring is another ring-shaped part of the bearing, located outside the balls or rollers. The outer ring cooperates with the inner ring and the balls to provide external support and fixation of the bearing. These three parts work together to form the basic structure of the bearing to support and transmit loads on the shaft, reduce friction, and enable the bearing to operate smoothly. Their materials and designs vary according to different applications and bearing types to meet specific load and working environment requirements.
