Abstract
The invention discloses a bearing convenient to dismount. A flexible cavity (4b), a working medium injection hole (4c) communicated with the flexible cavity (4b), a pushing plate (5), and a fixed plate (6) movably connected to the pushing plate (5) are arranged on an inner ring (4). By changing pressure of the fluid working medium in the flexible cavity (4b), the flexible cavity (4b) expands or shrinks to push the pushing plate (5), and the pushing plate (5) drives the fixed plate (6) to tightly hold or loosen the shaft, so that the bearing is conveniently fixed and dismounted; and meanwhile, fluid with relatively great specific heat is selected as the working medium, so that a great deal of heat generated by a rolling body further can be greatly absorbed, and therefore, the bearing can be cooled better.
Description
Technical field
The present invention relates to field of bearings, particularly relate to a kind of bearing of easy disassembly.
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: a kind of bearing of easy disassembly, described bearing comprises outer ring, rolling element, retainer, inner ring, described inner ring comprises lining ring, flexible cavity, working medium inlet, the outer surface of described lining ring contacts with described rolling element, the internal surface of described lining ring is fixedly connected with the outer surface of described flexible cavity, described flexible cavity end face is provided with the working medium inlet be connected with described flexible cavity, described working medium inlet can be closed, the internal surface of described flexible cavity is fixedly connected with some pieces of push pedals, described push pedal connects 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 flexible cavity, injected the working medium of high pressure by described working medium inlet, the pressure due to working medium makes flexible cavity expand, and promote push pedal, push pedal drives fixed plate to hold axle journal tightly again, is finally closed by working medium inlet.During dismounting, opened by working medium inlet, extracted out by the high-pressure working medium in flexible cavity and cavity pressure is released, flexible cavity shrinks, and drives push pedal, and push pedal drives fixed plate to loosen axle journal, thus can be unloaded by bearing easily.
As preferably, described push pedal is provided with a connecting rod, the end of described connecting rod is provided with expands portion A, described A inside, portion of expanding is provided with a spherically-shaped cavity, described hole is provided with opening on described lower end surface of expanding portion A, described fixed plate is provided with protuberance, the top of described protuberance is fixedly connected with a spherical portion B that expands, the described diameter expanding portion B is not more than the diameter in described hole, and expand the diameter of portion B be greater than described in the ultimate range of point-to-point transmission on the opening that expands on A lower end surface, portion, the described portion B that expands embeds in described hole, in the opening expanded on A lower end surface, portion described in described protuberance inserts, and can be freely movable.
As preferably, the surface that described push pedal is connected with described flexible cavity is provided with circular arc chamfering along its outer contour.Such setting avoids because jagged on push pedal upper surface edge or sharp edge easily stave flexible cavity, thus causes bearing accidental.
As preferably, the shape of described fixed plate on the radial cross section of bearing is fan-shaped, the end face of the described flexible cavity at described working medium inlet its place outstanding.Arranging so on the one hand makes fixed plate can better fit with stationary axle, thus increase area of contact bearing is fixed more firm, arrange so on the other hand and avoid described working medium inlet and other parts interfere.
Compared with prior art, the present invention has the following advantages: by arranging flexible cavity, the working medium inlet communicated with described flexible cavity, push pedal, the fixed plate that is flexibly connected with push pedal on inner ring.By the pressure changing flexible cavity inner fluid working medium, flexible cavity expanded or shrink thus promote push pedal, fixed plate is driven to hold tightly or loosen axle by push pedal again, thus complete the fixing of bearing and dismounting easily, select the larger fluid of some specific heats can also absorb the amount of heat of rolling element generation in a large number as working medium simultaneously, thus bearing can better be cooled.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.A bearing for easy disassembly, described bearing comprises outer ring 1, rolling element 2, retainer 3, inner ring 4.Described inner ring 4 comprises lining ring 4a, flexible cavity 4b, working medium inlet 4c, the outer surface of described lining ring 4a contacts with described rolling element 2, the internal surface of described lining ring 4a and the outer surface of described flexible cavity 4b are bonded together, described flexible cavity 4b end face is provided with the working medium inlet 4c be connected with described flexible cavity 4b, described working medium inlet 4c can close, and the end face of the described flexible cavity 4b at described working medium inlet 4c its place not outstanding.The internal surface of described flexible cavity 4b is bonded with six pieces of push pedals 5, the surface that described push pedal 5 is connected with described flexible cavity 4b is provided with circular arc chamfering along its outer contour, described every block push pedal 5 is equipped with a connecting rod 5a, the end of described connecting rod 5a is provided with expands portion A5b, described A5b inside, portion of expanding is provided with a spherically-shaped cavity 5c, and described hole 5c is provided with opening on described lower end surface of expanding portion A5b.Described fixed plate 6 is also provided with six, the shape of described every sheet fixed plate 6 on the radial cross section of bearing is fan-shaped, described every sheet fixed plate 6 is equipped with protuberance 6a, the top of described protuberance 6a is all fixedly connected with a spherical portion B6b that expands, the described diameter expanding portion B6b is not more than the diameter of described hole 5c, and described in expand the diameter of portion B6b be greater than described in the ultimate range of point-to-point transmission on the opening that expands on A5b lower end surface, portion.Portion of expanding B6c on described every sheet fixed plate 6 all embeds in the hole 5c in described every block push pedal 5, in the opening expanded on A5b lower end surface, portion described in described protuberance 6a inserts, and can be freely movable.
During installation, first by bearing housing on axle, end face bearing inner race 4 not being arranged working medium inlet 4c is overlapped with shaft shoulder face.Then in flexible cavity 4b, the hydraulic oil of high pressure is injected by described working medium inlet 4c, pressure due to hydraulic oil makes flexible cavity 4b expand, promote six pieces of push pedals 5 to move simultaneously, six fixed plates 6 are driven to hold axle journal tightly, make bearing be fixed on axle, finally working medium inlet 4c is closed.During dismounting, working medium inlet 4c is opened, the high pressure liquid force feed in flexible cavity 4b is extracted out cavity pressure is released, flexible cavity 4b shrinks, drive all push pedals 5 to reclaim, every block push pedal 5 drives every sheet fixed plate 6 to loosen axle journal again, thus can be unloaded by bearing easily.
