Abstract
The utility model relates to a kind of bearing sleeve structure, comprise bearing bush sleeve 1 and described hold groove 1d lining cylinder 1 is provided with through lining cylinder 1 two ends, groove 1d has comparatively wide arc gap under bearing sleeve free state, and after bearing sleeve is installed, bearing sleeve produces radial resiliently deformable.The utility model is because adopting bearing sleeve elastomeric radial as compensation way, can auto-compensation because material is different and temperature change and the radial interference amount that causes changes, active force between bearing sleeve and bearing is more stable, the serviceability temperature excursion be suitable for is wide, and because do not need king-sized elastic conjunction stress, and reduce overall structure weight.
Description
Technical field
The utility model relates to a kind of bearing sleeve structure, can because of the gap of the reason generations such as thermal expansion between auto-compensation and fitting seat.
Background technique
The lining of bearing sleeve, especially rolling bearing is widely used among different fields, such as, in aeronautical engineering.Concrete, bearing sleeve is used to gear-box, in gas turbine, transmission shaft, main reducing gear, accessory drive system.Another important application is the structure such as automobile gearbox and motor.
Existing bearing sleeve structure is mainly divided into 2 kinds, as shown in Figure 1, bearing sleeve is a sleeve with mounting flange to a kind of structure, and excircle of sleeve cylinder coordinates with the mounting hole of housing, the inner cylindrical surface of sleeve coordinates with outer race, and lining is fixed on housing by screw bolt and nut.This complicated structure, the existence because of bolt, nut and lining flange arrangement causes structure weight comparatively large, and structure is compact not.As shown in Figure 2, bearing sleeve is the sleeve of the rib that extends to the inside to 2nd kind of structure, and its external cylindrical surface is connected with interference fit with shell inner hole, and bearing sleeve inner cylindrical surface is connected with bearing top circle cylinder by small―gap suture or transition fit.The lining of this structure adopts the steel manufacture that wear-resisting single line expansion coefficient is less usually, and the housing larger aluminum-magnesium alloy manufacture that is linear expansion coeffcient, when operating temperature raises, magnitude of interference between lining and housing can reduce even to disappear, and then cause lining centering function to be lost, even lining and housing produce and move and wear and tear.
Summary of the invention
The purpose of this utility model is to provide a kind of bearing sleeve structure, described bearing sleeve has compact structure, lightweight feature, and when temperature variation, do not reduce because the linear expansion coeffcient relation different from case material causes installing magnitude of interference or disappear, ensureing the reliability of bearing-transmission.
The technical solution of the utility model is, described a kind of bearing sleeve structure comprises bearing bush sleeve and described holds groove lining cylinder 1 is provided with through lining cylinder two ends, groove has comparatively wide arc gap under bearing sleeve free state, and after bearing sleeve is installed, bearing sleeve produces radial resiliently deformable.The described two ends of holding lining cylinder are provided with flange, and described flange is positioned at two ends of lining cylinder, and extend respectively to the inner side and outer side of lining cylinder.
The utility model is provided with groove on lining cylinder, due between bearing sleeve from housing because linear expansion coefficient is different, when different operating temperatures produces radial fit gap trend, bearing bush sleeve can open automatically as spring, and then counteracting radial clearance, due to bearing sleeve resiliently deformable will much larger than produce because of temperature variation and radial clearance size between housing, bearing sleeve and housing at different operating temperature mutually between active force change very little, can effectively prevent between bearing sleeve and housing to turn.The flange arranged not only can play positioning action, can increase the elastic force between bearing sleeve and housing simultaneously.Compared with flanged (FLGD) bearing sleeve, the utility model structure is more simple, lightweight.Interference is relied on merely to ensure compared with the structure that lining and housing tighten together with the second, the utility model is because adopting bearing sleeve elastomeric radial as compensation way, can auto-compensation because material is different and temperature change and the radial interference amount that causes changes, active force between bearing sleeve and bearing is more stable, the serviceability temperature excursion be suitable for is wide, and because do not need king-sized elastic conjunction stress, it is thinner that the part that housing coordinates with bearing sleeve can be done, thus reduce overall structure weight.
