Embodiment Construction

[0010] Combine below figure 1 , To further explain the present invention.

[0011] Such as figure 1 As shown, a grease injection device for vehicle bearings includes a tightening screw 1, which is sequentially sleeved with a bearing platform 5, a grease head inner base 4, and a grease head outer base 3, a grease head inner base 4 and a grease head. The cavity formed by the head outer base 3 is connected with the pipe joint 7 through the grease pipe 9, and a gap for circulating grease is provided between the grease head inner base 4 and the grease head outer base 3. The grease inlet pipe joint and the grease injection pipe flow into the cavity formed by the grease head inner base and the grease head outer base, and flow into the corresponding position of the bearing through the gap in the cavity.

[0012] In a preferred example, a sealing ring is provided between the grease head inner base 4 and the grease head outer base 3 to better prevent the grease from leaking from the above-...

Abstract

The invention discloses a lower grease injection device used for a vehicle bearing. The lower grease injection device used for the vehicle bearing is characterized by comprising a tensioning screw rod (1), wherein the tensioning screw rod is sequentially sleeved with a bearing platform (5), an inner grease head base (4) and an outer grease head base (3); a cavity formed by the inner grease head base (4) and the outer grease head base (3) is connected with a pipe joint (7) through a grease circulating pipe (9); and a gap for circulating lubricating grease is formed between the inner grease head base (4) and the outer grease head base (3). The lubricating grease flows into the cavity formed by the inner grease head base and the outer grease head base through the pipe joint and a grease injection pipe, then flows into the corresponding position of the bearing from the gap in the cavity, so that the problems that the operation is inaccurate and inconvenient and the efficiency is not high when the lubricating grease is added to the vehicle bearing in the lower direction are solved.

Description

Technical field [0001] The invention relates to the field of grease injection, in particular to a grease injection device for vehicle bearings. Background technique [0002] Bearings are high-precision fixed parts in machinery. When other parts move relative to each other on the shaft, they are used to maintain the center position of the shaft and control the movement. Injecting grease before the bearing leaves the factory can reduce friction and wear, extend fatigue life, discharge frictional heat and cool down. At present, the traditional way of lubricating vehicle bearings is to use manual work to apply grease to the outer surface of the bearing manually. This way of applying grease by hand has the fact that most of the grease can stay on the outer surface of the bearing, and only rarely enter the inside of the bearing; at the same time, the amount of application is not easy to control. The lubrication effect is not achieved, and the efficiency is low, and the labor intensit...
