Abstract
The utility model relates to a grouped type bearing disassembling tool, comprising two arc-shaped structures which are connected with shafts with screw threads, one end of each arc-shaped structure is provided with an arc-shaped lug boss, the arc-shaped lug bosses are arranged on the bottom of a bearing which is to be disassembled, and the two arc-shaped structures are driven by the outward force exerted by the screw threads on the shafts so as to disassemble the bearing. When being adopted to disassemble bearings, the grouped type bearing disassembling tool can solve the problem of the large matching interference magnitude of the bearings and the bearing disassembly without large area force so as to enable the bearings not to be damaged during the disassembling process.
Description
Technical field
The present invention relates to a kind of extracting tool, especially a kind of extracting tool of bearing.
Background technology
In the existing bearing decomposable process, normally adopt direct punching press taking-up or hinge to carry pawl formula mechanism, this mechanism is little at matching allowance, lifts under the big situation in space, can reach the decomposition purpose.But it is little for the sort of space that utilizes, outer shroud is with accessory spare matching allowance is big mutually, but the bearing that does not have the large tracts of land application of force, decompose the instrument that does not just have moulding, the situation of back one end sealing especially is installed at those bearings, major part is to adopt the method for directly destroying, and bearing can not be utilized once more.Therefore more be badly in need of wanting efficiently a kind of, and can make bearing and extracting tool that the part that matches can not be damaged.
Summary of the invention
The objective of the invention is to design a kind of can be narrow and small in the space, outer shroud is with the accessory matching allowance is big mutually, but do not have the extracting tool of the bearing of the large tracts of land application of force, and can realize that bearing and the part that matches thereof are not damaged in unloading process.
Technical scheme of the present invention is: adopt an end to be provided with two arcuate structures of arc boss, the external diameter of lonely shape structure matches with bearing bore diameter to be unloaded, two arcuate structures close up the maximum of rear arc boss should be less than the internal diameter of waiting to unload bearing, and the external diameter of arc boss should less than with wait to unload the bearing internal diameter of accessory mutually.Two arc mechanisms are fixing by latch and one, and the diameter of axle matches with the internal diameter of arcuate structure, spool the other end be threaded.In dismounting during bearing, earlier two arcuate structures are put into the bottom of bearing to be removed by bearing bore diameter, in lonely shape structure, insert axle, axle and lonely shape structure are fixed by latch.This moment, arc boss was just in time fitted with the end face of bearing bottom, upwards implemented to lift power by the thread mechanism of axle, bearing removal is got off be not subjected to any destruction.
For another kind of improvement the of the present invention, for internal diameter is the dismounting of the bearing of taper, the arcuate structure that is adopted closes up the maximum of rear arc boss should be less than the minimum diameter of waiting to unload bearing, and the external diameter of arc boss should less than with wait to unload the bearing internal diameter of accessory mutually.Two arc mechanisms are fixing by latch and one, and the diameter of axle matches with the internal diameter of arcuate structure, spool the other end be threaded.Be provided with the ring that an internal diameter matches with the arcuate structure external diameter in the outside of arcuate structure.In dismounting during bearing, earlier two arcuate structures are put into the bottom of bearing to be removed by bearing bore diameter, in lonely shape structure, insert axle, be inserted in the ring that matches with its external diameter outward, axle and lonely shape structure are fixed by latch.This moment, arc boss was just in time fitted with the end face of bearing bottom, upwards implemented to lift power by the thread mechanism of axle, bearing removal is got off be not subjected to any destruction.
After adopting the present invention, because what adopt is the structure of assemble type, the bearing bottom can be cleverly removal force be implemented into during use and mean effort can be exerted all one's strength in bearing, not only can improve the efficient of dismounting, main is in the process of dismounting does not produce any destruction to bearing and the part that matches thereof.

The specific embodiment
As shown in Figure 1, two one ends are provided with the arcuate structure 1 of arc boss 2, the external diameter of arcuate structure 1 with wait that unloading bearing 5 internal diameters matches, two arcuate structures 1 close up the maximum of rear arc boss 2 should be less than the internal diameter of waiting to unload bearing 5, and the external diameter of arc boss 2 should less than with wait to unload replace the spare parts mutually 7 internal diameter of bearing 5.One end is threaded 8 axle 4, and the diameter of axle 4 matches with the internal diameter of arcuate structure 1, and two arcuate structures 1 are fixing by latch 6 with axle 4.In dismounting during bearing, earlier two arcuate structures 1 are put into the bottom of bearing to be removed 5 by bearing bore diameter, lonely shape structure 1 in, insert axle 4, axle 4 is fixed by latch 6 with lonely shape structure 1 and the gap 3 of two lonely shape structure 1 both sides formation is equated.This moment, arc boss was just in time fitted with the end face of bearing bottom, upwards implemented to lift power by the thread mechanism of axle, bearing removal is got off be not subjected to any destruction.
As shown in Figure 2, two two arcuate structures 1, the one end is provided with arc boss 2, arcuate structure 1 closes up the maximum of rear arc boss 2 should be less than the minimum diameter of waiting to unload bearing 9, one end is threaded 8 axle 4, the diameter of axle 4 matches with the internal diameter of arcuate structure 1, is provided with the ring 10 that an internal diameter matches with the arcuate structure external diameter in the outside of arcuate structure 1.Two arcuate structures 1 are fixing by latch 6 with axle 4.When the dismounting bearing, earlier two arcuate structures 1 are put into the bottom of bearing to be removed 5 by bearing bore diameter, in lonely shape structure 1, insert axle 4, be inserted in ring 10 in lonely shape structure 1 outside, axle 4 fixed by latch 6 with lonely shape structure 1 and the gap 3 of two lonely shape structure 1 both sides formation is equated.This moment, arc boss was just in time fitted with the end face of bearing bottom, upwards implemented to lift power by the thread mechanism of axle, bearing removal is got off be not subjected to any destruction.
