Description

Technical Field

[0001] The utility model relates to the technical field of bearing accessories, in particular to a shock-absorbing self-lubricating bearing seat. Background Art

[0002] A bearing seat is a mechanical part used to install and support bearings and connect bearings to bases or frames. It is commonly used in various mechanical equipment and devices to support and fix rotating parts so that they can remain stable during operation and withstand the load and force from rotating parts. The bearing seat plays an important supporting and connecting role in mechanical devices, ensuring that the bearings are correctly installed and operate stably, thereby ensuring the performance and reliability of mechanical equipment. During the operation of the machine, due to factors such as workload, speed changes and external vibrations, the bearing seat may be subject to shock and vibration. These vibrations will not only affect the operating stability of the mechanical device, but also accelerate the wear of the bearing and the bearing seat, reducing their service life. In order to protect the bearing and mechanical equipment, the bearing seat usually needs to have a shock-absorbing function that can effectively absorb and reduce vibration and impact. During the operation of the machine, relative sliding will occur between the bearing and the bearing seat, resulting in friction and wear. In order to reduce friction and wear and protect the surface of the bearing and the bearing seat, the bearing seat usually needs to have a self-lubricating function.

[0035] Working principle: when the bearing seat is needed, the bearing is placed on the upper surface of the lower fixing plate 3, and then the upper fixing plate 2 is placed on it, and then the first handle 6 is rotated. When the first handle 6 is rotated, the rotating column 5 can be driven to rotate.

Rotating the second handle 9 drives the second stud 13 to rotate, and then the second stud 13 can be taken out from the oil pipeline 11. Conversely, the oil pipeline 11 can be sealed.
