Description
Technical field
The utility model belongs to bearing machining equipment technical field, is specifically related to a kind of mechanism for bearing removal.
Background technology
In mechanical device, the rotation of mechanical part is normally realized by bearing and axle, bearing requires that in installation process the precision between the axle that is mated is higher, for the installation of the larger bearing of the magnitude of interference, generally adopt hot charge practice, but bearing in use for some time, because loss there will be various problem, need to remove, the bearing more renewed, bearing is when dismantling, due to structure restriction and bearing different from the thermal expansion amount of axle, the method for therefore not holding by heated mandrel is dismantled.Traditional method for dismounting uses the instrument such as vice or hammer to coordinate, realize the dismounting of axle upper bearing (metal), this kind of method for dismounting, its process is longer, waste time and energy, removal efficiency is low, meanwhile, when dismantling, careless slightlyly will injure auxiliary dismounting personnel or damaging other parts, for the problem existing for traditional method for dismounting, the existing various instruments for bearing removal emerge in an endless stream, and often kind of extracting tool has its pluses and minuses, but existing bearing extractor exists complex structure mostly, produce assembling trouble, high in cost of production problem.
Utility model content
For problems of the prior art, the purpose of this utility model is to design provides the mechanism for bearing removal that a kind of structure is simple, production cost is low.
Described a kind of mechanism for bearing removal, it is characterized in that comprising gripper shoe, strap, screw rod, described screw rod interts the medium position being arranged on gripper shoe, strap is equipped with on the supporting plate, and being symmetricly set on the both sides of screw rod, described strap is fan-shaped setting, and the lower end integral type of strap is provided with clamping part, the curved setting of described clamping part, the center of circle that arc clamping part is corresponding is positioned on the axis of screw rod.
Described a kind of mechanism for bearing removal, it is characterized in that described gripper shoe is symmetrically arranged with shifting chute, be provided with screw and nut in described shifting chute, described screw and nut are connected with the top of strap.
Described a kind of mechanism for bearing removal, is characterized in that described shifting chute is arranged along gripper shoe length direction.
Described a kind of mechanism for bearing removal, it is characterized in that the extended Access Division of the bottom surface of described clamping part, the radian of described Access Division is identical with the radian of clamping part.
Described a kind of mechanism for bearing removal, is characterized in that one end of described screw rod is fixedly installed handle.
Described a kind of mechanism for bearing removal, is characterized in that the bottom socket of described screw rod is provided with sleeve pipe.
The utility model structure is simple, reasonable in design, manufacturing cost is low, by being arranged on the clamping part on strap, can with the outer shroud close contact of bearing, Access Division is on the holder portion set, the bottom of bearing can be blocked in unloading process, the combination of clamping part and Access Division, the clamping of bearing can be made more firm, be convenient to the stable of unloading process and carry out, be arranged on the shifting chute of gripper shoe both sides, be convenient to the movement of strap position, realize dismantling the bearing of different size, expand the scope of application, easy to utilize.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1-gripper shoe, 2-strap, 3-screw rod, 4-clamping part, 5-shifting chute, 6-nut, 7-Access Division, 8-handle, 9-sleeve pipe.
Detailed description of the invention
The utility model is further illustrated below in conjunction with Figure of description.
As shown in Figure 1, a kind of mechanism for bearing removal of the utility model, comprise gripper shoe 1, strap 2, end with the screw rod 3 of handle 8, the interspersed medium position being arranged on gripper shoe 1 of screw rod 3, strap 2 is equipped with in gripper shoe 1, and be symmetricly set on the both sides of screw rod 3, annexation is specially, the shifting chute 5 along gripper shoe length direction is symmetrically arranged with at the two ends of gripper shoe 1, be spirally connected in this shifting chute 5 and be provided with screw and nut 6, screw and nut 6 are connected with the top of strap 2, and nut 6 is connected to the top of shifting chute 5 after installing.In order to save production cost, and alleviate the overall weight of product, strap 2 is arranged in fan-shaped, it is big top and small bottom, in order to realize the fixing of bearing, the lower end integral type of strap 2 is provided with clamping part 4, the curved setting of clamping part 4, the center of circle that arc clamping part is corresponding is positioned on the axis of screw rod, in order to the clamping realizing bearing is more stable, avoid rocking back and forth at unloading process middle (center) bearing, in the extended Access Division 7 of the bottom surface of clamping part, the radian of this Access Division 7 is identical with the radian of clamping part.In order to expand the scope of application, also can overlap sleeve pipe 9 in the bottom of screw rod, this sleeve pipe 9 can be selected according to the size of different bearing cross holes.
The utility model use procedure, when dismantling, the distance between two straps 2 is adjusted by screw and nut 6, make the clamping part close contact bottom the excircle of bearing and strap 2, Access Division 7 is blocked the bottom of bearing simultaneously, after adjusting the position of strap 2, screw the position that nut 6 is fastened and fixed clamping plate 2 further, after strap position fixes, hold handle 8 rotary screw 3, the bottom of screw rod 3 is contacted with the upper end of bearing shaft, be rotated down screw rod 3 further, axle can support out by the downward power of screwing of screw rod 3 from bearing, thus realize being separated of bearing and axle, this unloading process is simple, fast, the setting of shifting chute 5 simultaneously, be convenient to adjust according to the bearing of different size, expand its scope of application.For the bearing of band through hole, the bottom of screw rod 3 can be put sleeve pipe 9, then the bottom of the screw rod with sleeve pipe 9 is inserted in the through hole of bearing, guarantee that the outer wall of sleeve pipe and the inwall of bearing cross hole closely cooperate, adjust the position of strap 2 equally, then screw handle and drive bolt rotary, because outer race is firmly fixed by clamping part and Access Division, so rotate in process at screw rod, be easy to outer race to be separated with retainer and inner ring, complete dismounting.
