Bearing and bearing outer ring integrated structure

Abstract

The invention provides a bearing and a bearing outer ring integrated structure. The bearing comprises a bearing inner ring 12, the bearing outer ring integrated structure 11, a retainer 14 and a plurality of rolling balls 13, wherein the bearing inner ring 12 is a groove-shaped double-half ferrule with the gothic curvature, a circle of drawing groove is formed in the outer circumferential side ofthe bearing inner ring 12, and the retainer 14 is arranged on the outer circumference of the bearing inner ring 12; the bearing outer ring integrated structure 11 is arranged on the outer circumference of the retainer 14, the rolling balls 13 are arranged in an inner cavity formed by the bearing inner ring 12, the retainer 14 and the bearing outer ring integrated structure 11; the bearing outer ring integrated structure 11 comprises a bearing outer ring 110, a mounting edge 111, a first-section squirrel cage strip 112a, a second-section squirrel cage strip 112b, a supporting web 113, a boss 114 and a temperature measuring hole 115, wherein one end of the first-section squirrel cage strip 112a is connected to the bearing outer ring 110, and the other end of the first-section squirrel cage strip 112a is connected to the lower end of the supporting web 113; and one end of the second-section squirrel cage strip 112b is connected to the upper end of the supporting web 113.

Description

technical field [0001] The invention belongs to the field of aeroengines and gas turbines, and in particular relates to an integrated structure of a bearing and an outer ring of the bearing. Background technique [0002] The support system of aero-engine and gas turbine is mainly to support the engine rotor, transmit axial and radial loads and provide suitable support stiffness for the engine rotor, and meet the dynamic design requirements of the engine rotor system. [0003] With the continuous development of aero-engine and gas turbine technology, higher and higher requirements are put forward for bearings and supporting structures, which require bearings and supporting structures to complete their functions under complex working conditions and achieve light weight and high reliability requirements . [0004] The current aero-engine and gas turbine bearing support structures are as follows: figure 1 As shown, it generally consists of a bearing 1, a squirrel cage 2, a bea...
