AI Technical Summary
Technical Problem
After a long time of use, the sealing lip is worn, resulting in a reduction in the compression force between the oil seal and the transmission shaft, causing the problem of seal leakage.
Method used
A skeleton oil seal for mechanical transmission components is designed, including a skeleton oil seal body, a refueling tank, an oil suction block, a refueling port, a dust-proof seal cover and a coil spring. The lubricating oil is discharged by pressing the oil suction block and replenishing it between the oil seal main body and the transmission member, reducing wear and increasing sealing effect.
Benefits of technology
It effectively improves the life and sealing performance of the skeleton oil seal, prevents seal leakage, and improves the practicality of the device.

Abstract
The framework oil seal for the mechanical transmission component comprises a framework oil seal body, oil filling grooves are formed in the two ends in the framework oil seal body, an oil filling port is formed in the end, close to the center point in the framework oil seal body, of each oil filling groove, and an oil suction block is arranged at the end, close to the oil filling port, in each oil filling groove. A dustproof sealing cover penetrates through an internal thread of the oil adding groove, an elastic fixing block is arranged at one end in the dustproof sealing cover, a pressing rod penetrates through the elastic fixing block, and external threads are evenly arranged at the end, away from the oil suction block, in the oil adding groove. By arranging the framework oil seal body, the pressing rod, the elastic fixing block, the oil suction block, the oil adding groove and the oil adding port, lubricating oil in the oil suction block can be discharged through the oil adding port by pressing the oil suction block, the lubricating oil can be supplemented between the framework oil seal body and a mechanical transmission component, abrasion can be reduced, and the service life of the framework oil seal is prolonged. Meanwhile, an oil film formed by the lubricating oil can improve the sealing effect.
