What are the two types of friction lubrication in plain bearings?
(2) the bearing material and the bush structure have a great influence on the performance of the sliding bearing. The bearing material and the bush structure should be selected by considering various factors.
Chongqing plain bearings indicate that sliding bearings can be classified into the following categories:(1) sliding bearings can be divided into non liquid lubricated bearings and full liquid lubricated bearings according to their different states of friction. Full liquid lubrication bearings are divided into dynamic pressure lubrication bearings and hydrostatic lubrication bearings. Liquid lubrication bearings are mostly used in engineering. There are many kinds of sliding bearings: integral type, split type, automatic centering type, etc.. As the sliding bearing itself has some unique advantages, it can be applied to some special occasions, such as high speed, heavy load and high precision.
(3) non liquid friction sliding bearing calculation and checking, limit pressure P, to ensure that the lubricating oil film is not destroyed; limit value of PV, in order to ensure the bearing temperature is not too high, because the temperature is too high, easy to cause the rupture boundary of oil film.(4) according to the principle of hydrodynamic lubrication, the hydrodynamic lubrication sliding bearing is designed, which is mainly used in the continuous high speed operation.
