Description

Grease injector

The present invention is a grease injector in the form of a grease cup that is used for bearings or bushings, and can be used by supplying grease to a plurality of grease supply points as needed based on one grease injector, and also refilled or It relates to a grease injector that can be used as a cartridge.

In general, lubricating grease is injected into bearings and bushings such as ball bearings and roller bearings.

Hereinafter, a bearing will be described as an example. A grease cup is widely used as a device for supplying grease to a bearing.

Such grease cups can be divided into grease cartridge-only type and grease refill type according to grease injection method, and can be classified into spring discharge method, gas pressure discharge method and geared motor discharge method according to the driving method.

In addition, the grease cup has a shape in which the driving part and the extruded part are located below the driving part and the extruded part are located on the basis of the position of the driving part that generates the discharge power of the grease and the extruder that discharges the grease according to the discharge power of the driving part. It can be divided into forms.

In addition, grease cups can be divided into disposable and refilled types according to the method of use, and can be classified into explosion-proof and non-explosion-proof types according to the place of use.

However, the conventional grease cup is a type in which a grease cup is used for one grease supply point based on one grease cup, so that a lot of grease supply points are gathered and all or most grease supply points use less grease. Inefficiency and difficulties in installation work are caused by installing a plurality of grease cups in a relatively narrow space at each grease supply point.

In the conventional grease cup, the grease storage capacity of the grease cup is fixed based on one grease cup. Therefore, when the amount of grease used at the grease supply point is large, the replacement or refill cycle of the grease cup returns too quickly. Failure to replace the grease cup in time can cause grease supply points, ie wear, damage or breakage of bearings or bushings.

In addition, since the conventional grease cup is dedicated to any one of the refill type and the cartridge type, it is impossible to use the refill type and the cartridge type, and the general grease cup can be easily purchased on the market because it uses a dedicated battery. The application of the battery was not possible.

In addition, the conventional grease cup is impossible or difficult to visually check the remaining amount of grease, it was impossible to visually check the operating state and abnormalities or failure sites.
