Description

Technical Field

[0001] The utility model relates to the technical field of bearing retainers, in particular to a retainer structure of a low-noise automobile bearing. Background Art

[0002] In the automotive industry, bearings are one of the key components, and their performance directly affects the vehicle's driving stability, noise control and service life.

By designing the guide hole and the opening, the lubricating oil infiltration effect is better achieved, and at the same time, some debris is brought out through the guide hole by the lubricating oil, thereby reducing the noise generated by friction. By designing the rubber ring and the metal ring, the types of device materials are increased, thereby avoiding the noise caused by resonance.

[0004] Based on the above patent, the lubrication system of the traditional bearing retainer structure often cannot ensure that each roller is fully lubricated, resulting in greater friction and wear between the roller and the retainer due to insufficient lubrication. This friction not only generates a large amount of heat and accelerates the damage of the bearing, but also generates noise. In addition, the bearing retainer structure usually adopts an integral structure, which is not convenient for replacing parts separately. Therefore, the present utility model provides a low-noise automotive bearing retainer structure. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a low-noise automobile bearing cage structure, which solves the problem that the lubrication system of the traditional bearing cage structure often cannot ensure that each roller is fully lubricated, resulting in large friction and wear between the roller and the cage due to insufficient lubrication. This friction not only generates a large amount of heat and accelerates the damage of the bearing, but also generates noise. In addition, the bearing cage structure usually adopts an integral structure, which is not convenient for replacing parts individually.

[0008] The oil injection assembly comprises an annular conduit fixed inside the upper retainer, and an oil outlet conduit is fixed at the lower end of the annular conduit.

[0009] Preferably, the positioning assembly includes a first locking block fixed to the lower end surface of the upper retaining frame, a slot is provided inside the first locking block, a locking block is provided inside the slot, a second locking block is provided at the lower end of the locking block, and the lower retaining frame is located at the lower end of the second locking block.

[0011] Preferably, the rotating assembly includes a column that passes through the interior of the upper retaining frame and is rotatably connected, and the roller is located on the outer wall of the column, and the roller is rotatably connected to the column.

[0012] Preferably, the upper retainer and the lower retainer are symmetrically distributed, and the upper retainer and the lower retainer are made of aluminum alloy.

[0013] Preferably, the upper end of the annular conduit is fixed with an oil inlet extending to the outside of the upper retainer, the oil outlet conduit is evenly distributed along the inside of the lower end of the annular conduit, and the outlet of the oil outlet conduit is fluidly connected to the joint between the upper retainer and the roller.

[0016] First, the oil outlet duct of the utility model is evenly distributed along the lower end of the annular duct, ensuring that each roller can be fully lubricated, reducing friction and wear caused by insufficient lubrication, and the outlet of the oil outlet duct is connected to the joint of the upper retaining frame and the roller, which significantly reduces the friction between the roller and the retaining frame, reduces the heat and wear generated by friction, thereby extending the service life of the bearing, making the bearing run more smoothly and efficiently, and reducing the noise generated by friction. The interior of the roller is inlaid with sound insulation cotton, which absorbs the noise generated when the bearing is running, thereby improving the overall quiet effect.

[0017] Secondly, during installation, the present invention inserts the roller into the column on the lower retaining frame, and then engages and positions the internal slot of the first locking block at the lower end of the upper retaining frame with the second locking block and the block on the lower retaining frame. At the same time, the column is inserted into the roller, and then the locking bolt is rotated to complete the installation of the upper retaining frame, the lower retaining frame and the roller, ensuring the precise alignment of the upper retaining frame and the lower retaining frame during installation, thereby improving the assembly accuracy of the entire bearing, and also providing convenience when the retaining frame needs to be maintained and replaced, and can be more easily disassembled and reinstalled.
