The utility model provides a technical problem's technical scheme as follows:
the utility model relates to a novel universal joint bearing lubrication protection device, it includes sealing washer, sealed snare, bearing inner race and cross, the fixed outside that sets up at the bearing inner race of sealed snare, the cross setting is in the inboard of sealed snare and bearing inner race, the sealing washer is installed in the sealing washer cover, and the outside in close contact with of its outer end lip and cross, its innovation part lies in: the sealing ring is sleeved with a plurality of pressure relief oil grooves and pressure relief oil holes which are communicated with each other, and each pressure relief oil hole is provided with a pressure relief valve.
Furthermore, all the pressure relief oil holes are uniformly formed in the flange surface of the sealing ring sleeve, and the pressure relief oil grooves communicated with all the pressure relief oil holes are uniformly formed in the flange surface of the sealing ring sleeve and the positioning seam allowance.
Further, the angle formed by the flange surface of the sealing ring sleeve and the adjacent pressure relief oil hole is 30 degrees.
Further, the sealing ring is vulcanized and bonded in the sealing ring sleeve.
Further, the sealing ring sleeve is locked on the bearing outer ring through a plurality of screws.
Compared with the prior art, the utility model discloses its structural design is novel, and transformation and simple manufacture are practical, and when the bearing was annotated lubricating grease, the oil pressure was when relief valve settlement pressure within range, and the sealing washer lip overturns to the outside, and the old lubricating grease of discharge spills over until new lubricating grease and stops, and when the oil pressure exceeded relief valve settlement pressure within range, lubricating grease passed through the pressure release oil groove and the pressure release oilhole of sealed snare, then rethread relief valve reducing pressure, protection sealing washer.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs. The parts of the present invention not described in detail are the known techniques of those skilled in the art.
As shown in fig. 1 and 9, the novel universal joint bearing lubrication protection device of the present invention comprises a sealing ring 1, a sealing ring sleeve 2, a bearing outer ring 4 and a cross shaft 5, wherein the outer edge of the sealing ring sleeve 2 is a flange surface which is locked outside the bearing outer ring 4 by a plurality of screws 6, the inner side of the flange surface is a positioning spigot, and the sealing ring sleeve 2 is further provided with a mounting groove for mounting the sealing ring 1; the cross shaft 5 is arranged on the inner sides of the sealing ring sleeve 2 and the bearing outer ring 4, the sealing ring 1 is arranged in the mounting groove of the sealing ring sleeve 2, and the lip at the outer end of the sealing ring is tightly contacted with the outer side of the cross shaft 5; the sealing ring sleeve 2 is provided with a plurality of pressure relief oil grooves 7 and pressure relief oil holes 8 which are communicated, and each pressure relief oil hole 8 is provided with a pressure relief valve 3.
