Abstract
The invention discloses a bearing convenient to install. An inner ring (4) is provided with a cavity (4a), a working medium injection port (4b) and an open pore (4c) communicating with the cavity (4a), a piston (5), and a fixed piece (6) fixedly connected with the piston (5). By changing the pressure of a fluid working medium, the fixed piece (6) enclasps or releases a shaft, so that fixing and dismounting of the bearing can be conveniently completed; and after the working medium with relatively high specific heat is adopted, more heat produced in working of the bearing can be absorbed, so that the bearing can be better cooled.
Description
Technical field
The present invention relates to field of bearings, particularly relate to bearing easy for installation.
Background technique
Rolling bearing has application as standard piece more in the bearing of various rotatable parts.But because bearing inner race and axle are interference fit when current bearing is installed, be generally by knocking or installing by the mode that press machine is pressed into, also have and bearing heating made its inner ring swell and then be inserted on axle.The handling of bearing inconvenience all very in a word.
Summary of the invention
In order to overcome above-mentioned defect and deficiency the invention provides following technological scheme: bearing easy for installation, described bearing comprises outer ring, rolling element, retainer, inner ring, described inner ring inside is provided with a cavity, described inner ring end face is provided with the working medium inlet be connected with described cavity, described working medium inlet can be closed, described inner ring is provided with some perforates closest to the sidewall of stationary axle, described perforate is communicated with described cavity, be provided with the piston matched with it in described perforate, described piston is fixedly connected with a fixed plate.
During installation, first by bearing housing on axle, end face bearing inner race not being arranged working medium inlet is overlapped with shaft shoulder face, then in cavity, the working medium of high pressure is injected by described working medium inlet, due to the pressure of working medium piston ejected thus make all fixed plates hold axle tightly simultaneously, make bearing be fixed on axle, finally working medium inlet is closed.During dismounting, opened by working medium inlet, extracted out by the high-pressure working medium in cavity and cavity pressure is released, fixed plate no longer holds axle tightly, thus can be unloaded by bearing easily.
As preferably, described inner ring is provided with some boss outstanding to described cavity closest to the sidewall of stationary axle, and described boss is provided with described perforate, and described perforate runs through the sidewall at described boss and place thereof, and communicates with described cavity.Arrange like this and on the one hand the area of contact between piston and perforate is increased, make better tightness; Too increase the stroke that piston slides simultaneously, thus make bearing can mate the more diameter of axle.
As preferably, the shape of described fixed plate on the radial cross section of bearing is fan-shaped.Be arranged so that fixed plate can better be fitted with stationary axle like this, thus increase area of contact bearing is fixed more firm.
As preferably, the end face of the described inner ring at described working medium inlet its place outstanding.Such setting avoids described working medium inlet and other parts interfere.
Compared with prior art, the present invention has following beneficial effect: by arranging cavity, the working medium inlet communicated with cavity and perforate and piston and the fixed plate affixed with piston on inner ring.By the pressure of alter working medium, fixed plate held tightly or loosen axle, thus complete the fixing of bearing and dismounting easily, simultaneously after adopting the working medium that specific heat is higher, the heat produced when can also absorb more bearing working, thus bearing is better cooled.
Accompanying drawing explanation
Fig. 1 is the front view of the bearing in embodiment of the present invention when being arranged on axle.
Fig. 2 is the front view of the bearing in embodiment of the present invention when not being arranged on axle.
Fig. 3 is that the bearing in embodiment of the present invention faces whole-cutaway view when not being arranged on axle.
Fig. 4 is A portion enlarged view.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.Bearing easy for installation, described bearing comprises outer ring 1, rolling element 2, retainer 3, inner ring 4, described inner ring 4 inside is provided with a cavity 4a, described inner ring 4 end face is provided with the working medium inlet 4b be connected with described cavity 4a, described working medium inlet 4b can close, and the end face of the inner ring 4 at described working medium inlet 4b its place not outstanding, closest to the sidewall of stationary axle being circumferentially provided with uniformly six boss 4ds outstanding to described cavity 4a on described inner ring 4, each boss 4d is equipped with perforate 4c, described perforate 4c runs through the sidewall at described boss 4d and place thereof, and communicate with described cavity 4a, the piston 5 matched with it is equipped with in each perforate 4c, each piston 5 is fixedly connected with a fixed plate 6, the shape of each fixed plate 6 on the radial cross section of bearing is fan-shaped.
During installation, first by bearing housing on axle, end face bearing inner race 4 not being arranged working medium inlet 4b is overlapped with shaft shoulder face, then in cavity 4a, the hydraulic oil of high pressure is injected by described working medium inlet 4b, due to the pressure of hydraulic oil piston 5 ejected thus make six fixed plates 6 hold axle tightly, make bearing be fixed on axle, finally working medium inlet 4b is closed.During dismounting, opened by working medium inlet 4b, the high pressure liquid force feed in cavity 4a extracted out and cavity pressure is released, fixed plate 6 no longer holds axle tightly, thus can be unloaded by bearing easily.
Compared with prior art, the present invention has following beneficial effect: by arranging cavity 4a, the working medium inlet 4b communicated with cavity 4a and perforate 4c and piston 5 and the fixed plate 6 affixed with piston 5 on inner ring 4.Make fixed plate 6 hold tightly or loosen axle by the pressure of alter working medium, thus complete the fixing of bearing and dismounting easily.Simultaneously after adopting the working medium that specific heat is higher, the heat produced when can also absorb more bearing working, thus bearing is better cooled.
Below to invention has been detailed description, but the present invention is not limited to embodiment described herein.It will be appreciated by those skilled in the art that in the case without departing from the scope of the present invention, other changes and distortion can be made.Protection scope of the present invention is defined by the following claims.
