Oil-gas lubrication bearing pedestal with two-way nozzles, and using method of oil-gas lubrication bearing pedestal

Abstract

An oil-gas lubrication bearing pedestal with two-way nozzles comprises a floating bearing pedestal body and a fixed bearing pedestal body, and the floating bearing pedestal body and the fixed bearing pedestal body are arranged in parallel. A plurality of oil inlet pipelines are arranged in the fixed bearing pedestal body in the axial direction in a through mode. The oil-gas lubrication bearing pedestal further comprises an oil injection disc arranged between the two bearing pedestal bodies. A plurality of oil injection holes are annularly and evenly formed in the side, close to the fixed bearing pedestal body, of the oil injection disc. A plurality of oil ducts are formed inside the oil injection disc in the radial direction. The oil inlet pipelines, the oil injection holes and the oil ducts communicate in a one-to-one correspondence mode. The flow-out end of each oil duct is further provided with the corresponding nozzle in a communicating mode. The nozzles are divided into two groups with opposite oil injection directions, the numbers of the two groups of nozzles are equal, and the nozzles are evenly arranged in the circumference direction at intervals. The outer wall of the fixed bearing pedestal body and the floating bearing pedestal body are sleeved with an integral gland, and a pressing ring is fixedly arranged at the end of the integral gland and used for conducting axial limitation on the fixed bearing pedestal body. The oil-gas lubrication and oil distribution mode of two-way oil injection is adopted, oil-gas supply paths are independent from one another, and adjustment is convenient.

Description

technical field [0001] The invention relates to a bearing seat, in particular to an oil-air lubricated bearing seat with two-way oil injection and its use method. Background technique [0002] Bearing is an important and key basic component in equipment manufacturing, which directly determines the performance, reliability and life of the equipment; due to the harsh working environment and complex load conditions of the bearing, it must be long enough or even the entire life cycle of the equipment to avoid Maintenance, etc. During the design, development and manufacturing process, the bearings must be verified on the testing machine for corresponding simulated working conditions to provide reliable test data for research, design, manufacture and use, and provide a basis for the design, manufacture and use of bearings . [0003] In many cases, one end of the shaft is fixed when it rotates, so a stable bearing housing is required to support it. Because angular contact bearing...

AI Technical Summary

Problems solved by technology

Angular contact bearings are installed to adjust their stiffness by applying a load. As the speed increases, a greater axial load is required to maintain the stable operation of the bearing. At the same time, under high speed conditions, the requirements for the lubrication system also increase. Most of the bearing housings in the prior art cannot meet such requirements, resulting in the inability to achieve high-speed rotation with large loads
