Quick bearing

Abstract

The invention provides a quick-mounted bearing, belongs to the technical field of farm machinery parts, and solves the problem of difficult bearing oiling and disassembly. An easy-disassembled farm machinery bearing comprises a bearing inner ring, a bearing outer ring, and an annular rolling way arranged between the bearing inner ring and the bearing outer ring; a ball is arranged in the annular rolling way; a shaft hole is formed in the center of the bearing inner ring; an annular groove is formed in the end surface of one end of the bearing inner ring; a thread is arranged on the side surface of the annular groove; multiple oil injecting holes are formed in the bottom surface of the annular groove; oil ways are inserted between the other ends of the oil injecting holes and the annular rolling way, and are butted against the ball; one oil way is inserted between each oil injecting hole and the annular rolling way; and the multiple oil injecting holes are communicated with an annular hole formed in the bearing inner ring and coaxial with the bearing inner ring. An oil injecting pipe is inserted in the oil injecting holes for oil injection; lubricating oil can flow into the ball along with the oil way; when the bearing is disassembled, a cylindrical disassembly tool with a thread is screwed with the annular groove; and then, the disassembly tool is pulled out to conveniently disassemble the bearing.

Description

Technical field [0001] The invention belongs to the technical field of agricultural machinery accessories, and relates to an easily disassembled agricultural machinery bearing. Background technique [0002] Bearings are used to fix and reduce the friction coefficient of load during mechanical transmission. It can also be said that when other mechanical parts move relative to each other on the shaft, they are used to reduce the coefficient of friction during power transmission and keep the shaft center position fixed. Bearings are a pivotal component in contemporary machinery and equipment. [0003] Traditional bearing lubricating oil is added to the bearing through the lubricating nipple on the bearing seat. It is difficult to fill the ball between the bearing inner ring and the bearing outer ring when refueling, and the lubricating oil will flow everywhere. Can not reach the ball, which not only causes waste, but also easily damages the bearing due to insufficient lubricant. ...

AI Technical Summary

Problems solved by technology

[0003] Traditional bearings add lubricating oil to the bearing through the oil nozzle on the bearing housing. When adding oil, it must be added to the bearing inner ring and bearing outer ring The inside of the balls between them is more difficult, and the lubricating oil will flow around and cannot reach the balls, which will not only cause waste, but also easily cause bearing damage due to insufficient lubricating oil

Moreover, the current bearing disassembly methods mainly include knocking method, pushing method and thermal disassembly method. Due to the lack of support points, it is only possible to temporarily find a support point on the bearing for disassembly during disassembly. Therefore, the above methods will affect the bearing. cause some damage
