Abstract
The invention discloses a bearing dismantling device. The bearing dismantling device comprises a circular ring fixing sleeve composed of two half rings, wherein a flaky supporting ring is arranged in the circular ring fixing sleeve, the lower portion of the circular ring fixing sleeve is provided with an annular spigot, and the annular spigot is provided with a ferrule used for fixing the two half rings. When the bearing dismantling device is used for dismantling a bearing, the two half rings of the circular ring fixing sleeve hold the bearing; since the thickness of the flaky supporting ring in the circular ring fixing sleeve is small, the flaky supporting ring can be inserted in a gap between a gear and the bearing; next, the ferrule is arranged on the annular spigot in a sleeving mode to fix the two half rings, and then downward thrust can be applied to a gear shaft through a workpiece to dismantle the bearing from the gear shaft; as a result, the bearing is convenient and fast to demount and mount, and the problem that in the prior art, a bearing is hard to demount and mount because a gear and a shaft are of an integrated structure and the bearing and the gear are installed very closely is solved.
Description
Technical field
The present invention relates to a kind of instrument, particularly a kind of instrument dismantling bearing.
Background technology
Adopt bearings gear shaft very general in mechanical field application, when damaging appears in bearing or gear shaft, usually need bearing to remove from gear shaft, to carry out changing or keeping in repair.Usually adopting in prior art draws horse to dismantle bearing, but for the gear shaft that gear and axle are made of one, and bearing and gear installation site closely time, because the spacing between gear and bearing is less, make to draw the hook of horse to be fixed on bearing face, thus can not realize dismantling this bearing, cause the bearing dismantling difficulty of this mounting structure larger.
Summary of the invention
In view of this, the object of this invention is to provide a kind of bearing disassembling device, be structure as a whole and the large problem of bearing and gear installation site bearing dismantling difficulty closely to solve gear and axle.
Bearing disassembling device of the present invention, comprise the annulus fixed cover be made up of two semi-rings, be provided with plate-shaped support rings in described annulus fixed cover, the bottom of described annular fixed cover is provided with annular stopper, described annular stopper is provided with the lasso fixing two semi-rings.
Further, described bearing disassembling device also comprises by table top and is arranged on the workbench that the basifacial leg of platform forms, and described table top is provided with the locating slot coordinated with lasso, is provided with gear via hole in the middle part of described locating slot.
Further, described table top is also provided with imperial portal trestle, described imperial portal trestle is provided with casting die cylinder.
Beneficial effect of the present invention: bearing disassembling device of the present invention, when dismantling bearing, two of annulus fixed cover semi-rings are embraced bearing respectively, due to the plate-shaped support rings thinner thickness in annulus fixed cover, therefore it can insert the space between gear and bearing, again lasso is enclosed within annular stopper and two semi-rings are fixed, namely apply downward thrust by workpiece to gear shaft bearing is pulled down from gear shaft, convenient to disassembly, solve existing gear and axle is structure as a whole, and the problem that bearing and gear installation site bearing dismantling difficulty is closely large.
Accompanying drawing explanation
Fig. 1 is the structural representation of bearing disassembling device of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment bearing disassembling device, comprises the annulus fixed cover 1 be made up of two semi-rings, is provided with plate-shaped support rings 2 in described annulus fixed cover, the bottom of described annular fixed cover is provided with annular stopper, described annular stopper is provided with the lasso 3 fixing two semi-rings.
The present embodiment bearing disassembling device, when dismantling bearing, two of annulus fixed cover semi-rings are embraced bearing respectively, due to the plate-shaped support rings thinner thickness in annulus fixed cover, therefore it can insert the space between gear and bearing, again lasso is enclosed within annular stopper and two semi-rings are fixed, namely apply downward thrust by workpiece to gear shaft bearing is pulled down from gear shaft, convenient to disassembly, solve existing gear and axle and be structure as a whole and the large problem of bearing and gear installation site bearing dismantling difficulty closely.
In unloading process, because plate-shaped support rings 2 can bear larger pressure, therefore during fabrication by techniques such as the higher steel alloy of selection intensity or quenchings to increase the intensity of plate-shaped support rings, extend the service life of instrument.
As the improvement to the present embodiment, described bearing disassembling device also comprises by table top 4 and is arranged on the workbench that the basifacial leg 5 of platform forms, described table top is provided with the locating slot coordinated with lasso 3, gear via hole 6 is provided with in the middle part of described locating slot, this improvement is by worktable support and locate lasso and annulus fixed cover, can ensure that lasso and annulus fixed cover position are fixed in disassembly process, dismounting is more convenient.
As the improvement to the present embodiment, described table top is also provided with imperial portal trestle 7, described imperial portal trestle is provided with casting die cylinder 8, this improvement adopts casting die cylinder to apply pressure to gear shaft, gear shaft is separated with bearing, relative to the mode of manually knocking gear shaft, its operating efficiency is higher, more laborsaving.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
