Description
Technical field
The present invention relates to a kind of parts of hub reduction gear, especially a kind of shell structure of hub reduction gear.
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. In reducer shell, be full of fluid, reduce enclosure interior part temperature, prevent that part temperature rise is too high, also need in addition enough intensity, prevent that moment of torsion is excessive and rupture.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can conveniently in hub reduction gear, pass into and emit fluid, facilitate the shell structure that packs and take out and facilitate the hub reduction gear of putting into and taking out of sun gear supporting into of sun gear.
According to technical scheme provided by the invention, the shell structure of described hub reduction gear, it comprises cylindrical shell, bottom flange and top cover, be fixed with bottom flange in the bottom of cylindrical shell, top ends at cylindrical shell is connected with top cover, middle part at top cover is provided with boss, on boss, offer endoporus, on the flange of bottom, offer drive axle connecting hole, the first locating hole and the second locating hole, on the end face of top cover, be provided with depression, planet carrier connecting hole, sealing thread hole and bonnet installing hole, and sealing thread hole is at the cylindrical near top cover, in depression, offer planet axis connecting hole.
The center of circle of the center of circle of described drive axle connecting hole, the center of circle of the first locating hole and the second locating hole is on same circumference.
On the end face of top cover, evenly offer 3 ~ 6 depressions, in each depression, all offer planet axis connecting hole.
On the end face of the top cover between adjacent two depressions, be provided with described planet carrier connecting hole.
The center of circle in described sealing thread hole and the center of circle of bonnet installing hole are on same circumference.
Sealing thread of the present invention hole is arranged on hub reduction gear housing marginal portion, facilitates injection and the discharge of fluid; Hub reduction gear housing boss design of the present invention, is convenient to heat radiation; Hub reduction gear housing boss bore design, is convenient to the design of sun gear supporting and puts into and take out; On the top cover of hub reduction gear, depression is set, is convenient to alleviate overall weight.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A cutaway view of Fig. 1.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
The shell structure of this hub reduction gear, it comprises cylindrical shell 1, bottom flange 2 and top cover 3, be fixed with bottom flange 2 in the bottom of cylindrical shell 1, be connected with top cover 3 in the top ends of cylindrical shell 1, be provided with boss 4 at the middle part of top cover 3, on boss 4, offer endoporus 5, on bottom flange 2, offer drive axle connecting hole 6, the first locating hole 7 and the second locating hole 8, on the end face of top cover 3, be provided with depression 9, planet carrier connecting hole 10, sealing thread hole 11 and bonnet installing hole 12, and sealing thread hole 11 is at the cylindrical near top cover 3, in depression 9, offer planet axis connecting hole 13.
The center of circle of the center of circle of described drive axle connecting hole 6, the center of circle of the first locating hole 7 and the second locating hole 8 is on same circumference.
On the end face of top cover 3, evenly offer 3 ~ 6 depressions 9, at the interior planet axis connecting hole 13 that all offers of each depression 9.
On the end face of the top cover 3 between adjacent two depressions 9, be provided with described planet carrier connecting hole 10.
The center of circle in described sealing thread hole 11 and the center of circle of bonnet installing hole 12 are on same circumference.
When hub reduction gear work, in hub reduction gear housing, pass into enough fluid, fluid is circulated in hub reduction gear housing, take away the heat that part time job produces.
The design of boss 4 and endoporus 5, convenient in endoporus 5 places' design sun gears supportings, and be convenient to sun gear supporting and sun gear is put into from here;
Sealing thread hole 11 seals after packing bolt into, prevent that fluid from flowing out from here, screw out after bolt, design is in hub reduction gear housing marginal portion, can make fluid from then in hole, flow out smoothly, also can in hub reduction gear housing, inject fluid by this hole;
Equally distributed 5 depressions 9, can not only play the effect that makes housing back attractive in appearance, and can play the effect that reduces case weight;
The convenient fixing internal part herein that passes through of planet carrier connecting hole 10, makes the overall structure of housing more reliable and more stable.
