Bearing grease injecting tool

Abstract

The invention relates to a bearing grease injecting tool, which comprises a bottom plate, wherein the bottom plate is fixedly connected with one end of a lower template; the other end of the lower template is in threaded connection with an upper template; and a middle template is in threaded connection inside the upper template. The bearing grease injection tool is simple in structure, and is convenient to install; the upper template is used for compressing a bearing, two grease storing cavities are formed, and grease which is originally preserved in the tool is uniformly extruded onto a steel ball position in the middle of the inside of the bearing under the action of compression force, so that the quality and the stability of the bearing are improved greatly, and the service life of the bearing is prolonged.

Description

technical field [0001] The invention relates to the field of automobile equipment, in particular to a grease injection tool applied to bearings in automobiles and engineering machinery. Background technique [0002] Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. In order to improve the life and performance of the bearing during use, it is necessary to inject solid grease before assembly, inject the grease into the inside of the bearing, and make the grease reach the parts that need to be lubricated. For conventional bearings, use grease injection tooling to inject grease into the bearing surface (the surface is the gap between the ferrule and the cage), but for a bearing with a large width, the injection effect of the grease is uneven through the traditional grease injection tooling, and the ...

Problems solved by technology

In order to improve the life and performance of the bearing during use, it is necessary to inject solid grease before assembly, inject the grease into the inside of the bearing, and make the grease reach the parts that need to be lubricated. For conventional bearings, use grease injection tooling to inject grease into the bearing surface (the surface is the gap between the ferrule and the cage), but for a bearing with a large width, the injection effect of the grease is uneven through the traditional grease injection tooling, and the working part of the steel ball in the middle of the bearing cannot be injected with grease, resulting in the bearing Decreased quality and stability, reducing the service life of bearings

In addition, the injection of the amount of grease needs to be injected several times, which is time-consuming and laborious, and the injection efficiency is low
