Abstract
The invention relates to a bearing dismantling device, comprising a pull rod, a press ring and a regulating pad; the press ring is fixedly arranged in the dismantling direction of a bearing outer ring, the end surface of the press ring is matched with the that of a part provided with a bearing bush, a step arranged on the press ring is matched with the end surface of the bearing bush, the pull rod is in clearance fit with the bottom of the press ring, a disc is arranged at one end of the pull rod, the end surface of the disc is in contact with the end surface of the bearing outer ring and can move toward the dismantling direction along with the pull rod. The axial limiting of the bearing bush and the part provided with the bush during the disassembling of the bearing outer ring is realized, the bearing bush is prevented from being separated under the action of a disassembling force, the use safety is ensured, unnecessary repair or cost loss caused by replacement of a new product is reduced, and the production period is shortened.
Description
Technical field
The present invention relates to a kind of provision for disengagement, especially a kind of bearing disassembling device.
Background technology
Bearing is widely used revolving member in machine driving, is generally installed between the bearing insert on axle and casing.For taper roller bearing, interference fit is adopted between outer shroud and casing upper bearing (metal) lining during design, because taper roller bearing inner and outer rings is detachable, under during decomposition, inner ring is divided with axle, outer shroud is stayed in the bearing insert installing hole on casing, applying power need decompose separately on outer race end face, because outer race and lining are interference fit, in force process, be easy to lining to drive, thus depart from its correct installation site, exceed designing requirement.Continue the device of instructions for use for having, continuing easily to occur bearing non-normal working when using, vibrate large etc. abnormal, affect use safety, again reprocessing or change new product makes cost improve, production cycle prolongation, causes the unnecessary wasting of resources.
Summary of the invention
The object of the present invention is to provide a kind of bearing disassembling device, mainly for the decomposition of taper roller bearing outer shroud, after ensureing that outer race decomposes, it is firm that bearing insert coordinates with casing end face, guarantees use safety, avoids part to reprocess or change, economize on resources, shorten the production cycle.
Technical scheme of the present invention is, described bearing disassembling device comprises pull bar, pressure ring, adjusting pad, pressure ring is fixedly installed on the direction of outer race dismounting, in round cup shape, end face is coordinated with the parts end face installing bearing insert by adjusting pad, and the end face of pressure ring also arranges bossed step, and described step coordinates with bearing insert end face, the internal diameter of pressure ring is between the internal-and external diameter of lining, and the degree of depth is greater than the width of outer race; Pull bar coordinates with the bottom gap of pressure ring, and one end is designed with disk, the end face of described disk can with the end contact of outer race, and can to move to disassembly direction along with pull bar; Pull bar through bottom pressure ring, and is provided with nut by screw thread.Make another kind of mode of the present invention, will be placed in fixing plane bottom pressure ring, the end of pull bar be positioned at bottom pressure ring, and the end of pull bar and the distance from bottom of pressure ring are greater than the width of outer race.
Pressure ring is fixed by the present invention, and pressure ring contacts with bush end face, in the process of dismounting bearing, ensures that lining does not move; By arranging the thickness of adjusting pad, when can ensure that pressure ring is fixed, with fixing of bush end face; In force process, by rotary nut, pull pull bar, and then realize outer race and move to disassembly direction, complete dismounting; For another kind of embodiment, can mechanical type be adopted, exert a force directly to the lower disk to pull bar, complete dismounting.Present invention achieves the axial limiting of the parts of bearing insert and mounting bush when outer race decomposes, avoid under the effect of decomposing force, deviating from of bearing insert, ensure that use safety, reduce the unnecessary cost allowance reprocessed or change new product and cause, shorten the production cycle.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of another kind of scheme of the present invention.
Detailed description of the invention
As shown in the figure, described bearing disassembling device comprises pull bar 2, pressure ring 1, adjusting pad 3, pressure ring 1 is fixedly installed on the direction that outer race 6 is dismantled, in round cup shape, end face is coordinated with parts 4 end face installing bearing insert by adjusting pad 3, and the end face of pressure ring 1 also arranges bossed step, and described step coordinates with bearing insert 5 end face, the internal diameter of pressure ring 1 is between the internal-and external diameter of lining 5, and the degree of depth is greater than the width of outer race 6; Pull bar 2 coordinates with the bottom gap of pressure ring 1, and one end is designed with disk 8, the end face of described disk 8 can with the end contact of outer race 6, and can to move to disassembly direction along with pull bar 2; Pull bar 2 through bottom pressure ring 1, and is provided with nut 7 by screw thread.Make another kind of mode of the present invention, will be placed in fixing plane bottom pressure ring 1, the end of pull bar 2 be positioned at bottom pressure ring 1, and the end of pull bar 2 and the distance from bottom of pressure ring 1 are greater than the width of outer race 6.
