Description

Technical Field

[0001] The invention belongs to the technical field of bearing assembly, and in particular relates to a fast ball separation device used for bearing processing. Background Art

[0002] A bearing is a mechanical element whose main function is to support a mechanical rotating body and reduce the mechanical load friction coefficient of the equipment during the transmission process. The working principle of a bearing is to replace sliding friction with rolling friction. It is generally composed of two rings, a set of rolling elements and a cage. It is a highly versatile, standardized and serialized mechanical basic component. Due to the different working conditions of various machines, various requirements are put forward for rolling bearings in terms of load capacity, structure and performance. For this reason, rolling bearings need to have a variety of structures. However, the most basic structure is composed of an inner ring, an outer ring, rolling elements and a cage - usually called the four major parts. The components and structures of the bearing include: Inner ring: usually tightly fit with the shaft and run with the shaft. Outer ring: usually transition fit with the bearing seat or the mechanical housing hole, and plays a supporting role. Rolling element: usually arranged evenly between the two rings in the bearing with the help of a cage for rolling motion. It can be a ball, cylinder, cylinder or needle, which is responsible for rolling motion, thereby reducing friction. Cage: also called a retainer, it keeps the rolling elements evenly spaced and ensures that they do not collide during operation. The bearing distributes the load through multiple rolling elements to prevent single-point contact, which will increase wear and friction. This distribution can reduce the contact between moving parts, thereby ensuring smooth rotation. The shape, size and number of rolling elements directly affect the load capacity and performance of the bearing. In addition to evenly separating the rolling elements, the cage can also guide the rotation of the rolling elements and improve the internal lubrication performance of the bearing.

[0003] The rolling elements in the most common bearings at present are mostly steel balls.
