Description

Technical Field

[0001] The utility model relates to the technical field of self-lubricating bearings, in particular to a self-lubricating bearing device resistant to high temperature and high pressure. Background Art

[0002] At present, the self-lubricating bearing has an oil storage chamber inside. Through the clever design of the oil-slinging plate, the lubricating oil can effectively act on the bearing shell, realizing the self-lubricating mechanism inside the bearing. In terms of lubricating oil sealing, we use advanced rotary dynamic sealing technology, with the help of high-quality sealing rings, to ensure that the shaft and the self-lubricating bearing fit tightly, eliminating the possibility of oil leakage.

[0003] However, it is worth noting that current self-lubricating bearings are prone to burning of bearings in shaking devices. This is mainly due to the failure of the lubricating oil film to build, resulting in unnecessary friction between the shaft and the bearing. In addition, the weight of the lubricating oil film and the lubricating oil also affects the lubrication effect of the bearing to a certain extent. Therefore, we still need to continuously optimize the bearing design to ensure that it can maintain stable and efficient lubrication performance in various working environments. In view of this, in-depth research on the above issues led to the creation of this case. Utility Model Content

[0021] Specifically, the adsorption and drainage structure includes: an L-shaped adsorption and drainage pipe 5, a lubricating oil tank 6, a transfer inner box 7, a lifting and sealing disc 8, a pull-out disc 9, a pull-out ring rubber ring 10, a pair of lifting magnets 11, a transmission metal rod 12 and a feeding L-shaped pipe 13;
