Open deep groove ball bearing

Abstract

The utility model discloses an open type deep groove ball bearing which comprises a bearing outer ring, a bearing inner ring is arranged in the bearing outer ring, and an outer slide way is arranged on the inner wall of the bearing outer ring. The bearing retainer has the beneficial effects that the reinforcing ring is arranged on one side of the retainer and can improve the bearing capacity of the retainer, so that the influence of non-uniform stress of the retainer is reduced, and the oil injection port is formed in the reinforcing ring, so that when the friction between the rolling beads and the retainer is increased due to insufficient lubricating oil in the bearing, the bearing retainer is prevented from being damaged. Lubricating oil can be injected into the reinforcing ring through the oil injection port and flows into the inner cavity of the retainer through the reinforcing ring, that is, the lubricating oil flows onto a bearing rolling way when the rolling balls rotate, and the oil injection port can supplement the lubricating oil in the bearing to reduce friction force generated by rotation of the rolling balls. The protection frame is prevented from being subjected to thermal stress due to heat generated by large friction force, and the retainer is prevented from being damaged due to expansion deformation.

Description

Technical Field

[0001] The utility model relates to the technical field of deep groove ball bearings, in particular to an open deep groove ball bearing. Background Art

[0002] The main function of open deep groove ball bearings is to support rotating parts and reduce friction. At the same time, they can withstand radial loads and certain axial loads. This type of bearing is suitable for high-speed and even ultra-high-speed operation environments. It has the characteristics of low friction coefficient, high maximum speed, and a wide range of sizes and forms. It is widely used in precision instruments, low-noise motors, automobiles, motorcycles, general machinery and other industries.

[0003] During use, the cage of the existing open deep groove ball bearing can correctly guide the rolling balls to roll on the rolling track. However, when the bearing is overloaded or impacted by external force, the cage will be unevenly stressed and break. The frictional heat generated by the high-speed rotation of the rolling balls will cause the cage to be subjected to thermal stress, which in turn causes the cage material to expand and deform, and even cause the cage to be damaged. Therefore, a new type of open deep groove ball bearing is urgently needed to solve these problems. Utility Model Content
