Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in the drawings, the present embodiment provides a universal joint pin with a lubricating function, which includes a universal joint pin 1 and a transmission shaft yoke 2;

the cross shaft 1 comprises a shaft head 3 and a shaft sleeve 4 sleeved on the shaft head 3, and the transmission fork is connected with the shaft sleeve 4; be equipped with a plurality of annular bosss 5 on the inner wall of axle sleeve 4, the bottom of boss 5 with spindle nose 3 is contradicted, owing to through the face-to-face contact, has increased area of contact, avoids the line contact to reduce wearing and tearing, the atress is even, and life extension is adjacent form oil storage tank 6 between the boss 5, when the axle sleeve 4 rotates, can make the lubricating oil in the oil storage tank 6 lubricate spindle nose 3, thereby reduce the wearing and tearing between spindle nose 3 and the axle sleeve 4, be equipped with logical oil groove 7 on the boss 5, logical oil groove 7 makes adjacent oil storage tank 6 intercommunication, makes the lubricating oil in the oil storage tank 6 can flow to logical oil groove 7 in, directly lubricates boss 5 and the contact surface of spindle nose 3, makes the lubrication of spindle nose 3 more abundant. And a lubricating hole 8 is formed in the outer side of the shaft sleeve 4, and the lubricating hole 8 is communicated with the oil storage tank 6. When the shaft sleeve 4 rotates, lubricating oil in the oil storage tank 6 flows outwards through the lubricating hole 8, the ground connected with the shaft sleeve 4 and the transmission shaft fork 2 is lubricated, friction damage is reduced, the shaft sleeve 4 can be cooled, and the service life of the universal joint is prolonged.
