Description

Anti-sway retaining frame device for automatic transport trolley and implementation method

Technical Field

The present invention relates to the technical field of bearing retainers, and in particular to an anti-sway retainer device for an automatic transport trolley and an implementation method thereof.

Background Art

A cage (also called a bearing retainer) is a bearing part that partially wraps all or part of the rolling elements and moves with them to isolate the rolling elements, and usually guides the rolling elements and keeps them in the bearing.

When rolling bearings are working, especially when the load is complex and the bearings rotate at high speed, the cages have to bear great centrifugal force, impact and vibration, there is great sliding friction between the cages and the rolling elements, and a lot of heat is generated. The combined effect of force and heat can lead to cage failure, and in severe cases, it can cause the cage to burn and break. Therefore, the cage material is required to have good thermal conductivity, good wear resistance, low friction coefficient, low density, a certain combination of strength and toughness, good elasticity and rigidity, expansion coefficient similar to that of the rolling elements, and good processing performance. In addition, the cage is also affected by chemical media such as lubricants, lubricant additives, organic solvents and coolants.

Commonly used cages are divided into metal cages and non-metal cages according to the type of material. There are also composite cages. Special-purpose bearing cages should also meet the requirements of special working conditions, such as high temperature resistance, corrosion resistance, self-lubrication (for use in vacuum) or non-magnetic.

The existing automatic transport trolley retainer has the following defects:

1. When the automatic transport trolley is moving, vibration and friction are likely to occur between the bearings and the axles, thus affecting the smooth movement of the trolley.
