Description
The technical field is as follows:
the invention relates to the technical field of mechanical structures, in particular to a bearing structure capable of separating grease.
Background art:
the existing motor lubricating grease cleaning mode is basically that the waste grease after the bearing lubrication is recovered by adopting a waste grease collecting box grease receiving mode, waste grease is extruded out by utilizing the self gravity of the lubricating grease and the grease injecting pressure of the lubricating grease, the principle is specifically realized in such a way that after the grease in a bearing chamber cavity is full, new grease can be continuously injected into a grease injecting device, the waste grease is extruded out by utilizing the newly injected grease, the waste grease is discharged, and after the grease receiving box is full, the waste grease in the grease receiving box is periodically cleaned up and then is continuously received.
However, due to the high viscosity of the lubricating grease, the lubricating grease cannot well fall into the waste grease receiving box, and the waste grease recovery treatment of the grease lubrication motor is not facilitated. When the high load high speed operation of bearing, can produce a large amount of heats, simultaneously because the inside lubricating grease of bearing cavity can't be cleared up to traditional grease collection mode, therefore lead to the interior grease of bearing chamber cavity to pile up, be unfavorable for the heat of bearing to give off, and the axle also can rub with lubricated grease when high-speed. A large amount of heat is generated, so that the temperature of the bearing is increased, the service life of the bearing is shortened, and the failure rate of the bearing is increased. In addition, increased friction losses of the bearings and grease also reduce certain efficiencies of the motor. Especially, the offshore wind generating set can affect the generating capacity of the set and bring about great maintenance cost of the set, thereby causing great economic loss. Therefore, the crawler-type structure can well solve the problem of waste grease collection of the motor with the grease lubrication structure, greatly reduce the failure rate of the bearing, prolong the service life of the bearing and reduce a large amount of direct economic loss and indirect economic loss for enterprises.
The invention content is as follows:
the invention aims to provide a bearing structure capable of separating grease, which reduces the failure rate of a motor bearing, improves the operation reliability of a motor, reduces the difficulty of maintenance work and reduces the economic loss of enterprises.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention provides a bearing structure capable of separating grease, which comprises a bearing body, wherein a bearing seat is arranged outside the bearing body, one side of the bearing seat, close to a motor body, is connected with a bearing inner cover, the other side of the bearing seat is connected with a bearing outer cover, a bearing chamber cavity is formed between the bearing outer cover and the bearing body, a retainer ring fixing nut and a waste grease collector are sequentially arranged in the bearing chamber cavity, the retainer ring is abutted against the bearing body, the waste grease collector comprises an annular mounting frame, a crawler belt is embedded on the annular mounting frame, the crawler belt is annularly arranged on the annular mounting frame, and a crawler belt tooth sheet is arranged on the end surface of one side of the crawler belt, facing the circle center of the annular mounting frame.
The track teeth are equally spaced on the track.
The annular mounting frame is close to one end of the bearing outer cover and is provided with a mounting seat, and a handle is installed in the mounting seat.
The mounting seat is provided with a groove, one end of the handle is provided with a guide rail, the guide rail is inserted into the groove, and the other end of the handle is provided with an arc-shaped holding part.
The bearing structure capable of separating grease has the beneficial effects that: novel structure, therefore, the clothes hanger is strong in practicability, through the waste grease collector who adds on the bearing body, waste grease in clearance bearing room cavity that can be convenient, can also take out the annular mounting bracket of waste grease collector through the handle structure who adds, then utilize the track tine that sets up on the track to take out the waste grease in the bearing room cavity, the track clean up that will have waste grease again, make simple to operate, maintainability is strong, the cost of manufacture is low, can effectively reduce motor bearing fault rate, improve motor operational reliability, reduce the maintenance work degree of difficulty, reduce the economic loss of enterprise.
