Vertical type thrust sliding bearing

Abstract

The invention discloses a vertical type thrust sliding bearing. The vertical type thrust sliding bearing comprises a thrust head, a guide tile, a guide bearing seat, a thrust tile, a thrust disc and a high-pressure oil system, wherein the guide tile sleeves the outer part of the lower section of the thrust head; the guide tile is mounted in the guide bearing seat; the thrust tile and the thrust disc are mounted in the guide bearing seat and are located at the lower end of the thrust head; the high-pressure oil system comprises a thrust tile oil injection device, a high-pressure oil inlet pipe, a high-pressure oil ring pipe and splitters; one end of the high-pressure oil inlet pipe is communicated with the high-pressure oil ring pipe; the plurality of splitters are arranged and are mounted at the top of the guide bearing seat at intervals; the high-pressure oil ring pipe is communicated with the splitters; the thrust tile oil injection device comprises a plurality of high-pressure oil distribution pipes and a high-pressure oil integrated receiving pipe; one end of each high-pressure oil distribution pipe is communicated with the corresponding splitter and the other ends of the high-pressure oil distribution pipes are communicated with the high-pressure oil integrated receiving pipe; the high-pressure oil integrated receiving pipe is inserted into an oil hole of the thrust tile. The vertical type thrust sliding bearing disclosed by the invention is compact in structure, wide in applicable working condition range and high in economical efficiency.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a vertical thrust sliding bearing. Background technique [0002] Thrust sliding bearings are sliding bearings that bear axial thrust and limit the axial movement of the shaft. Thrust bearings whose two friction surfaces are completely separated by a fluid film are divided into hydrodynamic thrust bearings and hydrostatic thrust bearings, which are suitable for high and medium speed operation. Thrust bearings whose two friction surfaces cannot be completely separated by a fluid film work under boundary lubrication and are only suitable for low-speed operation. [0003] Vertical thrust sliding bearings are widely used in high-voltage motors, gearboxes, and water pumps installed vertically in large pumping stations and power plants. one of the key components. Such as figure 1 As shown, the vertical thrust sliding bearing is composed of a housing (guide bearing housing 3), a rot...

AI Technical Summary

Problems solved by technology

For vertical thrust sliding bearings with high-pressure jacking, the layout of high-pressure oil pipelines is relatively complicated. During installation, replacement and maintenance, it is necessary to disassemble the bearing housing and other components, which is extremely inconvenient to operate.
