Description

Technical Field

[0001] The utility model relates to the field of bearings, and specifically to a feeding device for an internal diameter grinding machine of an agricultural machinery bearing unit. Background Technique

[0002] The main function of a bearing is to reduce friction, thus making rotation smoother and reducing energy consumption. Between the rotating "shaft" and the rotating support part, friction is inevitable. However, when a bearing is applied between these two components, it can effectively reduce this friction and ensure smoother rotation. This not only extends the service life of the equipment but also reduces the additional energy consumption caused by friction.

[0003] The existing patent CN214771290U discloses a feeding device for a bearing grinding machine. Two stop blocks I block the outer ring of the bearing, and two stop blocks II do not block the outer ring of the bearing. The arranged outer rings of the bearings roll along the guide rail and stop when they touch the stop block I. According to the size of the bearing, the position of the stop block II is controlled. In the main viewing direction, the upper rod of the stop block II is just between the first and second outer rings of the bearings. When the stop block II moves inward, the upper rod can be inserted between the two outer rings of the bearings. Then the stop block I moves outward, and the first outer ring of the bearing rolls down. Then the stop block I moves inward to reset, and the stop block II moves outward to reset. The whole outer ring of the bearing moves forward and returns to the initial state. By repeating the operation, the outer rings of the bearings fall into the feeding area of the grinding machine in sequence.

[0004] When the existing device is in use, when the bearing flows into the grinding machine through the feeding device, the larger bearing is not blocked by the feeding device and has a chance to fly out and cause damage. Content of the Utility Model
