Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of bearing assembly, and particularly relates to a quick ball separating device applied to bearing processing. BACKGROUND

[0002] A bearing is a mechanical element, and its main function is to support a mechanical rotating body to reduce the mechanical load friction coefficient of equipment in a transmission process. The working principle of the bearing is to replace sliding friction with rolling friction, and the bearing is generally composed of two rings, a group of rolling bodies and a retainer, and is a mechanical basic part with high universality, standardization and serialization. Due to different working conditions of various machines, different requirements are put forward for rolling bearings in terms of load capacity, structure and use performance. Therefore, rolling bearings need to have various structures. However, the most basic structure is composed of an inner ring, an outer ring, rolling bodies and a retainer, which is usually referred to as four major parts. The components and structure of the bearing include: the inner ring, which is usually tightly matched with the shaft and rotates together with the shaft. The outer ring, which is usually transitionally matched with the bearing seat or the hole of the mechanical shell, plays a supporting role. The rolling body, which is usually uniformly arranged between the two rings by the retainer for rolling movement, can be a ball, a cylinder, a cylinder or a needle, and is responsible for rolling movement to reduce friction. The retainer, also known as a holder, uniformly separates the rolling elements and ensures that they do not collide during operation. The bearing distributes the load through multiple rolling bodies to prevent single-point contact, as single-point contact can exacerbate wear and friction. This distribution reduces contact between moving parts, ensuring smooth rotation. The shape, size and number of rolling bodies directly affect the load capacity and use performance of the bearing, and the retainer not only uniformly separates the rolling bodies, but also guides the rotation of the rolling bodies and improves the lubrication performance of the bearing.

[0003] At present, the rolling bodies in the common bearing are mostly steel balls.
