A Method of Reducing Bearing Friction Coefficient by Changing Lubricating Oil Under Variable Load

Abstract

The invention belongs to the technical field of sliding bearings, and specifically relates to a method for reducing the friction coefficient of bearings by changing lubricating oil under variable loads. The method is realized based on an oil-lubricated sliding bearing with an oil drain distributor. The specific steps include: Measure the maximum load fluctuation range when the sliding bearing is working, and obtain the known viscosity as η 0 The c-v / w curve of the lubricating oil and set the low value fluctuation range L% of the friction coefficient, deduce the viscosity value of the lubricating oil used in different load ranges one by one from the maximum load to the minimum load of the sliding bearing, through the oil Distributors supply lubricating oils of different viscosities for different load ranges to ensure that the bearings operate at a lower level of friction coefficient, reduce the friction power consumption of the bearings, reduce bearing wear, prolong the life and operating performance of the bearings, and facilitate the system Calculation and analysis of power loss, etc.; simple structure, ingenious design concept, low manufacturing cost, broad market prospect, and friendly application environment.

Description

Technical field: [0001] The invention belongs to the technical field of sliding bearings, and specifically relates to a method for reducing the friction coefficient of a bearing by changing lubricating oil under variable loads, supplying lubricating oils with different viscosities for different load ranges, and controlling the friction coefficient of the bearing within a low value range. And can quantitatively select the viscosity of the lubricating oil required. Background technique: [0002] Bearings are widely used in various fields of national economy and national defense affairs. In actual work, the load it bears is not constant, and the fluctuation range is very large under many working conditions, such as high-end bearings used in power equipment, high-power construction machinery, mining machinery, etc., will face regular or irregular load changes . When the bearing load fluctuates greatly, it is easy to cause the lubrication state to change, resulting in a rapid i...

Problems solved by technology

However, under complex working conditions, the ability of a single lubricating medium to maintain good lubrication is limited. When the load fluctuates greatly, it will still cause changes in the lubrication state, which will increase the friction coefficient, aggravate wear, and cause a series of situations such as bearing failure.
