Bearing calcium-sodium base grease oil ejector

Abstract

The invention relates to an oil ejector, in particular to a bearing calcium-sodium base grease oil ejector in oil replacement of four wheels of an automobile and maintenance of construction machinery. The bearing calcium-sodium base grease oil ejector consists of a working platform system, an oil injection system and a bearing seat system. The oil ejector has the advantages that: the oil ejector is provided with the working platform system, the oil injection system and the bearing seat system; grease in an oil cylinder is pressed into a bearing by a piston pressure rod, and the inside and outside of the grease-filled bearing are filled with the grease, so the bearing has long service time and the defect of short service time of the bearing due to the traditional manual grease filling method which only applies the grease on the surface of the bearing is overcome. A repairman can fill the grease easily with hands being basically not stained with the grease, so the aims of saving raw materials, reducing environment pollution, saving time and saving labor are fulfilled. Simultaneously, a series of oil injector, bearing seat, bearing retaining ring and bearing reversing handle is designed according to different models and different diameters of the bearing, so the grease can be injected to bearings with all models and diameters.

Description

technical field [0001] The invention relates to an oiler, in particular to a calcium-sodium-based grease oiler for bearings in four-wheel oil change of automobiles and construction machinery maintenance. Background technique [0002] With the adjustment and development of the national automobile industry and construction machinery, after-sales service and scheduled maintenance have been put on the agenda. High-quality, high-efficiency maintenance is the requirement and need of the times, and the simple and fast scientific process will surely replace the backward manual maintenance methods in the past. [0003] Car four-wheel oil change and various mechanical maintenance. At present, most of the bearing maintenance is done by adding calcium and sodium base grease by hand, that is, butter. There are no special tools. The oil is mainly pressed into the bearing by hand, and the hands are covered with sticky butter. If you are not careful, you will still get butter on your body ...

AI Technical Summary

Problems solved by technology

Because the calcium sodium base grease is particularly viscous, it cannot be wiped off on hands and clothes, and it has to be washed with gasoline, resulting in a waste of raw materials

What's more important is to press the oil into the bearing by hand, often it is only applied to the surface of the bearing, and no oil is added between the bearing balls, which shortens the service life of the bearing
