AI Technical Summary
The sealing sleeve is prone to cracking at the oil pipe joint, leading to seal failure and affecting the service life of the bearing.
Design an oil pipe joint installation structure for a bearing bush, wherein the center line of the groove of the oil pipe joint is offset from the end center, and the outer wall of the groove is provided with a side wall surface. The side wall surface is clearance-fitted with the channel to reduce the chance of the sealing ring entering the gap and to provide appropriate space when the sealing ring deforms.
By focusing on clearance fit, the occurrence of seal ring breakage is reduced, the service life of the seal ring is improved, the sealing effect is enhanced, and the service life of the sealing sleeve is extended.
