A bearing inner ring and bearing outer ring assembly device

Abstract

This utility model discloses a bearing inner ring and bearing outer ring fitting device, relating to the field of bearing fitting technology. It includes a base on which the bearing outer ring and bearing inner ring are placed. A mounting bracket is provided on the top of the base, with fixing components on the left and right side walls of the mounting bracket. A feeding pipe is movably inserted through the top of the mounting bracket, with one end connected to an inlet pipe. A connecting plate is fitted onto the outer wall of the feeding pipe. A third electric telescopic rod is provided at the top of the mounting bracket, with one end connected to the top of the connecting plate. Under the action of the actuating component, this device can bring the outer wall of the bearing inner ring into contact with the inner wall of the bearing outer ring. Steel balls then enter between the bearing inner and outer rings through the inlet and feeding pipes. The actuating component then moves the bearing inner ring left and right, distributing the steel balls between the inner and outer rings, thus completing the bearing fitting. The bearing inner ring experiences minimal stress and will not be damaged.

Description

Technical Field

[0001] This utility model relates to the field of bearing assembly technology, specifically to a bearing inner ring and bearing outer ring assembly device. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. When assembling a bearing, steel balls need to be placed between the inner and outer rings of the bearing, and then the inner ring is restored to be centered with the outer ring.

[0003] The self-aligning roller bearing assembly device, disclosed in CN218510022U, belongs to the field of bearing assembly technology. It includes a platform, the upper surface of which is fixedly connected to the lower surface of a first conveyor plate. A positioning module is provided within the first conveyor plate, and the positioning module includes two positioning plates located within the first conveyor plate. The opposing surfaces of the two positioning plates are fixedly connected to both ends of the same spring. This self-aligning roller bearing assembly device, by setting up a positioning module and limiting components, can ensure the accuracy of bearing assembly and improve the efficiency of bearing assembly through automated assembly. Simultaneously, it positions the bearing to ensure that the rollers can be accurately driven into the cage, and by limiting the bearings, it can prevent bearing misalignment during assembly, which could prevent the rollers from being accurately driven into the cage.

[0004] However, existing assembly devices subject the inner ring of the bearing to significant stress during assembly, which can easily damage the inner ring. Therefore, we propose an assembly device for the inner and outer rings of the bearing. Utility Model Content
