A large tilting pad bearing with adjustable radial and circumferential fulcrum coefficients

Abstract

The invention discloses a large tilting pad bearing with adjustable radial and circumferential fulcrum coefficients, which comprises a bearing seat a and a bearing seat b, the bearing seat a and the bearing seat b form a ring structure and are located at the center of the inner ring of the ring structure There is a journal at the position, and a plurality of bearing pads evenly distributed along the circumferential direction are arranged between the journal and the bearing seat. Connected with the bearing seat, the front end of the hanging pin and the bearing bush form a rotating pair in spherical contact, the rear end of the hanging pin is connected with the bearing seat through threads, and the bearing seat is connected through the cooperation of bolt a and cylindrical pin a. The invention is used to solve the problem of adjusting the position of the fulcrum of the tilting pad bearing in large rotating equipment, so as to improve the stability and bearing capacity of the tilting pad bearing.

Description

technical field [0001] The invention relates to the technical field of tilting pad bearings, in particular to a large tilting pad bearing with adjustable radial and circumferential fulcrum coefficients. Background technique [0002] The bearing pad of the tilting pad bearing can swing freely with the change of speed, load and bearing oil temperature, so as to automatically adjust to the best position to form the oil wedge, so it has good stability and large bearing capacity, and can be tilted. The tile bearing has the advantages of unlimited size and convenient installation, so it is widely used in large rotating equipment such as steam turbines and water turbines. However, due to the limitations of the above equipment's harsh working conditions and excessive volume, the size of the tilting pad bearing used in this equipment has become correspondingly larger. The fulcrum position of the tile bearing is adjusted to a certain extent. [0003] At present, the axial positionin...
