Elastic tilting-pad sliding bearing

Abstract

An elastic tilting-pad sliding bearing comprises a bearing body, a plurality of elastic tilting pads and bearing covers. The elastic tilting pads are symmetrically arranged on the inner side of the bearing body, and the bearing covers are arranged on the two sides of the elastic tilting pads and matched with seam allowances on the two sides of the bearing body. Each elastic tilting pad comprises a tilting pad body and an elastic body arranged on the inner side of the tilting pad body, wherein a mounting gap is formed between the elastic body and the tilting pad body, and fixing plates are connected at the two ends of the tilting pad body and the elastic body and fastened through bolts. According to the elastic tilting-pad sliding bearing, the problems that the machining technology process of the elastic tilting pads is complex and the cost of the elastic tilting pads is high are solved, the whole structure is scientific and reasonable, mounting and use are convenient, the production process is simple, the maintenance cost is reduced, the manufacturing cost is low, usage, popularization and promotion are easy, and the elastic tilting-pad sliding bearing can be widely applied to the matching use of various kinds of tilting-pad sliding bearings.

Description

technical field [0001] The invention relates to an elastic tiltable pad sliding bearing. Background technique [0002] Radial tilting pad sliding bearings are widely used in high-speed rotating machinery such as steam turbines, compressors, and gearboxes to solve the problem of oil film oscillation when the rotor supported by sliding bearings runs at high speed; For stable operation under high speed conditions, it is particularly important to select sliding bearings with strong vibration damping capabilities. The tilting pad radial sliding bearings have good vibration damping properties, strong bearing capacity, low power consumption, simple structure, and convenient maintenance. , It is the preferred choice for modern high-power, high-speed rotating machinery. [0003] The existing elastic tilting pad sliding bearings are generally manufactured by integrally processing the elastic tilting pads, so that the produced tilting pad sliding bearings are not only complicated in p...
