SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the ball bearing that exists among the prior art and fix a position when being connected with other equipment location unstable, easily appear rocking in the positioning process, the bearing inner race easily wears out when the ball bearing uses, wearing and tearing more serious technical problem in the transportation.
The technical scheme of the utility model is that: closed double-row angular contact ball bearing is provided with bearing inner race and bearing outer race, is provided with the bearing groove between bearing inner race and bearing outer race the bearing groove in be provided with the bearing ball, the inside of bearing inner race be provided with the dactylotheca, the dactylotheca set up along the bearing inner race, and dactylotheca and bearing inner race between be provided with vertical strip, vertical strip and dactylotheca between form L shape structure the outer wall of bearing outer race on be provided with locating component, locating component be circle column structure, the direct suit of locating component in the outside of bearing outer race locating component and bearing outer race between be provided with scalable locking valves.
The positioning component is a positioning rubber ring, and a positioning transverse groove is formed in the positioning rubber ring.
And a telescopic thimble is arranged in the positioning transverse groove.
The top of the telescopic thimble is provided with a pressure spring, and the end part of the telescopic thimble is provided with an arc thimble head.
And a grease injection channel is arranged between the bearing ball and the bearing groove and is of a sinking structure.
The bottom of the grease injection channel is provided with a grease suction fiber cluster, and an oil suction hole is formed in the grease suction fiber cluster.
The utility model has the advantages that: through being provided with the dactylotheca in ball bearing's inside, rely on the dactylotheca to let ball bearing's interior terminal surface avoid wearing and tearing, can carry out the protection of internal surface in the transportation, be provided with positioning component on the bearing outer lane, can rely on positioning component to let ball bearing and other equipment's location be connected more high-efficient and safety.
