A quick-change spring-supported tilting pad thrust bearing

Abstract

The invention discloses a quick-replacement type elastic-cushion-supported tilting pad thrust bearing. The quick-replacement type elastic-cushion-supported tilting pad thrust bearing is mainly composed of a thrust plate (1), elastic-cushion-supported tilting pads, a retaining check ring (5) and a supporting ring (6). Each elastic-cushion-supported tilting pad is composed of a pad face material layer (2), a pad base body (3) and an elastic cushion (4), wherein the pad face material layer (2), the pad base body (3) and the elastic cushion (4) are bonded through super epoxy resin or other superglue of the same type. According to the quick-replacement type elastic-cushion-supported tilting pad thrust bearing, elastic dovetail grooves (7) and the retaining check ring (5) are ingeniously utilized, and therefore the quick-replacement type elastic-cushion-supported tilting pad thrust bearing is simple in structure and greatly improves the reliability. Besides, it is easier to replace an abraded and ablated pad, and the pad can be quickly replaced without disassembling the bearing or a thrust ring. The quick-replacement type elastic-cushion-supported tilting pad thrust bearing is high in practicability and can be widely applied to the ship field, the water pump field, the water turbine field, the food processing field and the like.

Description

technical field [0001] The invention belongs to the technical field of thrust bearings, in particular to a spring-supported tilting pad thrust bearing with a dovetail groove positioning and locking structure, which can quickly replace wear, ablation, and corrosion tiles. The bearing has simple structure, safety and reliability, and is easy to install. And it is convenient to replace the tiles, especially the effects of vibration reduction and load sharing are outstanding. Background technique [0002] Water-lubricated thrust bearings are widely used in food processing, pharmaceutical production, and water pumps due to their advantages of environmental protection, simple structure, and no need for sealing. The ability of hydrodynamic lubrication is poor. [0003] The Chinese patent "A Thrust Bearing Supported by an Elastic Pad" (CN201439803) discloses a thrust bearing supported by an elastic pad, in which a rubber pad is placed under each tile. The elastic pads and thrust p...

AI Technical Summary

Problems solved by technology

Mitchell bearings have strong adaptability to variable loads, but the load is not evenly distributed on each pad, which results in uneven wear of thrust bearing pads

The Kingsbury bearing overcomes the above shortcomings. Its advantages lie in uniform load distribution, flexible adjustment, and compensation for misalignment and deflection of the rotor, but the structure is also extremely complicated.

The above two bearings do not have the ability to reduce vibration and noise, and can only be used for oil lubrication
