Large-sized sleeve bearing thrust-face reverse-lubricating and lubricating oil cooling method

Abstract

The invention relates to a reverse lubrication for pushing face of huge journal bearing and the lubricating oil cooling method, belonging to the bearing technology area. In the invention, the lubricating oil carried by left impeller with oil thrower disc and oil scraping plate supplies to the right pushing face by left oil inlet channel, on the opposite hand, the lubricating oil carried by right impeller with oil thrower disc and oil scraping plate supplies to the left pushing face by right oil inlet channel. After bearing and pushing face are lubricated by the lubricating oil, the lubricating oil returns to the oil pool by oil return pipe and it is cooled by cooler effectively so as to ensure that the pushing face can obtain full lubrication and cooling to form continuous oil film under the condition that the bearing is inclined. The invention can ensure continuous stable lubrication with oil film is formed under the condition that the bearing is inclined so as to improve the stability of bearing and avoid the loss of huge equipments such as large ball mill, rotary kiln, ship propulsion motor and cooling machine so on, because of the bearing failure.

Description

technical field [0001] The invention relates to a method in the technical field of bearings, in particular to a method for reverse lubrication and cooling of lubricating oil on the thrust surface of a large sliding bearing, which is used in the field of manufacturing large sliding bearings working under inclined conditions. Background technique [0002] Large sliding bearings are widely used in large rotary machinery, such as large ball mills, rotary kilns, ship propulsion motors, coolers, etc. For this type of bearing with heavy load and low speed, especially under the working conditions of non-horizontal installation, establishing a safe and reliable lubricating oil film sliding protection is the focus of research in recent years. A lot of research has been done on low-speed sliding bearings at home and abroad, and some design schemes have been proposed, including mechanical lubrication methods for large sliding bearings and self-lubricating methods for bearings. In order...
