Abstract
The utility model relates to a pressing shaft support of a press-assembling tool for a hub reduction gear shell. The pressing shaft support comprises a pressing shaft support body in the shape of a round pipe, wherein a bottom round ring body is integrally connected onto the outer wall of the bottom end of the pressing shaft support body; planetary shaft positioning holes are formed in the bottom round ring body; a positioning external step is arranged on the top end of the pressing shaft support body; the axis of the pressing shaft support body is arranged in parallel with the axis of the bottom round ring body; the axis of the pressing shaft support body is perpendicular to the bottom end face of the bottom round ring body. The pressing shaft support can enable planetary shafts to be rapidly and correctly pressed into the hub reduction gear shell; according to the pressing shaft support, the structure is simple, the operation is easy, the assembly efficiency is improved, and the use cost is reduced.
Description
Technical field
The utility model relates to a kind of erecting device of hub reduction gear housing, especially a kind of last item support of hub reduction gear housing press-fitting tool.
Background technology
Hub reduction gear is one of part of automotive axle, can play the main deceleration of reduction and pass the rotating speed of coming, and increases the effect of gear end moment of torsion.Hub reduction gear housing is the support accessory on hub reduction gear, and on the one hand, hub reduction gear housing plays a part to load other all parts of hub reduction gear, and hub reduction gear housing plays a part to connect wheel hub semiaxis and wheel hub on the other hand.On hub reduction gear housing, will pack planet axis into, the hole on planet axis and hub reduction gear housing is interference fit, and to have boss, boss be machined surface hub reduction gear housing bottom, and common installation way is not easy to pack planet axis into hub reduction gear housing.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of last item support that can make planet axis can conveniently pack in hub reduction gear housing, improve efficiency of assembling and the hub reduction gear housing press-fitting tool of assembly precision, assurance hub reduction gear reliability of operation into is provided.
The technical scheme providing according to the utility model, the last item support of described hub reduction gear housing press-fitting tool, it comprises the last item rack body that is tubular, be connected with bottom torus at the bottom of last item rack body outer wall, on the torus of bottom, offer planet axis locating hole, step outside the top ends of last item rack body is provided with location, the toric axis in the axis of last item rack body and bottom is set in parallel, and the axis of last item rack body is perpendicular to the toric bottom face in bottom.
The toric bottom face in the bottom face of described last item rack body and bottom is in the same plane.
Described planet axis locating hole has 4 ~ 6, and they are and are evenly arranged.
The utility model can be pressed in hub reduction gear housing planet axis fast and accurately; The utility model is simple in structure, easy to operate, improves efficiency of assembling, reduces use cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A cutaway view of Fig. 1.
Fig. 3 is use state diagram of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
The last item support of this hub reduction gear housing press-fitting tool, it comprises the last item rack body 1 that is tubular, be connected with bottom torus 2 at the bottom of last item rack body 1 outer wall, on bottom torus 2, offer planet axis locating hole 3, step 4 outside the top ends of last item rack body 1 is provided with location, the axis of the axis of last item rack body 1 and bottom torus 2 is set in parallel, and the axis of last item rack body 1 is perpendicular to the bottom face of bottom torus 2.
The bottom face of the bottom face of described last item rack body 1 and bottom torus 2 is in the same plane.
Described planet axis locating hole 3 has 4 ~ 6, and they are and are evenly arranged.
When the utility model uses, must coordinate and press-fit base 5, planet axis is pressed into by press in the planet axis installing hole 8 of hub reduction gear housing 7, first should be placed on workbench press-fiting base 5, and then hub reduction gear housing 7 is placed on and is press-fited on base 5, prevent that hub reduction gear housing 7 from directly contacting workbench and making the bottom surface of hub reduction gear housing 7 produce damage.
Last item support of the present utility model positions in hub reduction gear housing 7 by locating outer step 4, is vertically placed on hub reduction gear housing 1 bottom, both steady, can keep again accurate location.
Because planet axis will guarantee to be vertically pressed in planet axis installing hole 8, in order to avoid planet axis is pulled by planet axis installing hole 8, in the time that planet axis is installed, first planet axis locates by planet axis locating hole 3, after the axis of planet axis locating hole 3 and planet axis installing hole 8 is basically identical, planet axis is put into 8 mouthfuls of planet axis installing holes by planet axis locating hole 3, planet axis is pressed in planet axis installing hole 8 with press to first planet axis installation.Take out last item support of the present utility model, according to abovementioned steps, second planet axis 6 is installed and installs successively 5 planet axis.
