Title:
METHOD FOR REDUCING CHURNING LOSS OF COMBINED THRUST BEARING
Document Type and Number:
WIPO Patent Application WO/2016/033994
Kind Code:
A1
Abstract:
A method for reducing a churning loss of a combined thrust bearing, comprising the following steps: a, injecting lubricating oil into an oil sump (8) to enable a guide bearing bush (9) to be immersed in the lubricating oil; b, providing a high-level oil tank (1) with a one-way vent valve (13), utilizing an oil supplying pump (3) to inject the lubricating oil in the oil sump (8) into the high-level oil tank (1), and injecting the lubricating oil in the high-level oil tank (1) between a runner plate (15) and a thrust pad (10) and/or between a bearing thrust head (14) and the guide bearing bush (9), such that the lubricating oil circulates between the oil sump (8) and the high-level oil tank (1), and an oil inlet quantity of the high-level oil tank (1) is greater than an oil outlet quantity thereof; c, with an increase in the oil quantity of the high-level oil tank (1), enabling, via the one-way vent valve (13), the oil outlet quantity of the high-level oil tank (1) and the oil inlet quantity of the high-level oil tank (1) to be gradually the same, a level of the lubricating oil in the oil sump (8) being below the thrust pad (10). The method solves the problem in the prior art that a thrust bearing is immersed in the lubricating oil in operation, thus avoiding generating a churning loss.
