Bearing used grease filling device

Abstract

The invention relates to a bearing used grease filling device, which includes a fixation pipe and a filling head that are connected fixedly, wherein a grease hole is arranged in the fixation pipe and the filling head, a plurality of circles of filling holes are arranged on the filling head and are communicated with the grease hole. The bearing used grease filling device is characterized by further including O-shaped seal rings, one groove is arranged on the filling head at each of the two ends outside the filling holes, and one O-shaped seal ring is arranged in each groove. The bearing used grease filling device has the advantages of evenly greasing a bearing and reducing grease waste.

Description

technical field [0001] The invention relates to a grease filling device, in particular to a grease filling device for bearings. Background technique [0002] The current grease filling device for bearings includes a fixing piece and a filling head, and the fixing piece and the filling head are fixedly connected. There are grease holes in the fixing piece and the filling head, and several rings are arranged on the filling head. The hole, the filling hole and the grease hole are connected; when the grease filling device for the bearing is working, the bearing is first set on the filling head, and the grease is injected into the bearing through the grease hole and the filling hole. Grease easily flows from the surface of the needle roller to the gap between the two ends of the needle roller. When the grease filling pressure is increased, the grease will be injected from both ends of the bearing, which will affect the operators and waste a lot of grease. Good lubrication to the...

[0002] The current grease filling device for bearings includes a fixing piece and a filling head, and the fixing piece and the filling head are fixedly connected. There are grease holes in the fixing piece and the filling head, and several rings are arranged on the filling head. The hole, the filling hole and the grease hole are connected; when the grease filling device for the bearing is working, the bearing is first set on the filling head, and the grease is injected into the bearing through the grease hole and the filling hole. Grease easily flows from the surface of the needle roller to the gap between the two ends of the needle roller. When the grease filling pressure is increased, the grease will be injected from both ends of the bearing, which will affect the operators and waste a lot of grease. Good lubrication to the needle roller surface or raceway of the bearing, when the pressure gauge of the greaser machine is in the normal range, it is easy for the grease to flow from the needle roller surface to the accumulation at both ends of the needle roller, and when the grease is added to the bearing, remove the bearing from When the filling head is pulled out, the remaining grease that emerges from the filling hole will be carried along, which is easy to cause uneven grease in the inner diameter of the bearing.
