A tilting pad thrust bearing supported by an elastic disc

Abstract

The invention discloses a tilting-pad thrust bearing supported through an elastic disc. The tilting-pad thrust bearing is mainly composed of a thrust disc (1), a tilting material layer (2), the elastic disc (3) and a copper ring (4). The copper ring (4) is bonded to the lower surface of the elastic disc (3) and has the functions of supporting the elastic disc (3) and improving the strength of the elastic disc (3). The tilting material layer (2) is bonded to bosses (5) of the elastic disc and used for bearing axial thrust from the thrust disc (1). The tilting-pad thrust bearing has the beneficial effects of being simple in structure, convenient to machine and the like; the integral machining manner is adopted in the elastic disc, and it can be guaranteed that tiles have high planeness; and according to the thrust bearing, the character of deformation coordination of elastic materials is ingeniously utilized, and the thrust bearing has outstanding performance in the aspects of vibration reducing, noise lowering, tile load equalizing, lubricating and the like.

Description

technical field [0001] The invention belongs to the technical field of thrust bearings, and in particular relates to a tilting pad thrust bearing supported by an elastic plate and having the effects of vibration reduction and load equalization. Background technique [0002] The rim thruster has been paid more and more attention due to its advantages of low vibration, low noise, saving the interior space of the cabin and so on. Lifespan, foreign countries have been keeping secrets about this technology. Therefore, it is necessary to develop this technology independently. [0003] Tilting pad thrust bearings at home and abroad are mainly divided into two categories: Mitchell bearings and Kingsbury bearings. Mitchell bearings have a strong adaptability to variable loads, but the load is not evenly distributed on each pad, which causes uneven wear of the thrust bearing pads. The Kingsbury bearing overcomes the above shortcomings. Its advantages lie in uniform load distributio...

AI Technical Summary

Problems solved by technology

The elastic pads and thrust pads are limited by cylindrical pins, so the rubber pads and thrust pads can only be installed horizontally, which limits their application range and can only be used in occasions that carry vertical thrust such as vertical water turbines; the thrust bearing is designed only Considering its load balancing function and oil lubrication environment, it cannot be used for water lubrication
