Description

Technical Field

[0001] The utility model belongs to the technical field of needle roller bearings, in particular to a mounting structure of a needle roller bearing for a textile machine. Background Art

[0002] Needle roller bearings are roller bearings with cylindrical rollers. Relative to their diameter, the rollers are thin and long. Such rollers are called needle rollers, so bearings with such rollers are called needle roller bearings. They are often installed in positions where radial installation dimensions are restricted for support. Needle roller bearings use multiple cylindrical needle rollers and have a large load bearing capacity, so they can be widely used in mechanical transmission machines such as textile machines, washing machines, electric vehicles, automobiles, and motorcycles.

[0003] Needle roller bearings used in textile machines need to withstand a relatively high rotation speed, so they need to be lubricated in a timely manner. However, the existing needle roller bearings have a fixed structure and cannot properly apply lubricating oil to the needle rollers, which results in the needle roller bearings making noise and stalling after a period of use. Utility Model Content

When lubrication is completed, the sealing ring is clamped back to one side of a limit plate, and refueling is completed. The device can quickly refuel the needle roller bearing, and the disassembly and installation process is simple, the installation structure is reasonable, and it is convenient for the staff to operate quickly, thereby extending the service life of the needle roller bearing, and solving the problem that the existing needle roller bearing has a fixed structure and cannot well feed the lubricating oil into the needle roller, thereby causing the needle roller bearing to have noise and rotation jam after a period of use.
