Abstract
The invention relates to a shell structure of a hub reduction gear. The bottom end portion of a cylinder body is fixed with a bottom end flange, and the top end portion of the cylinder body is integrally connected with a top cover. A boss is arranged in the middle of the top cover, and an inner hole is formed in the boss. A drive axle connection hole, a first positioning hole and a second positioning hole are formed in the bottom end flange. A concave portion, a planet frame connection hole, a sealing threaded hole and a rear cover installation hole are formed in the top face of the top cover, the sealing threaded hole is close to the outer circle of the top cover, and a planet shaft connection hole is formed in the concave portion. According to the shell structure of the hub reduction gear, the sealing threaded hole is formed in the edge portion of a shell of the hub reduction gear, and therefore oil liquid is convenient to infuse and discharge; due to the design of the shell boss of the hub reduction gear, heat dissipation is facilitated; due to the design of the shell boss inner hole of the hub reduction gear, a sun wheel bearing is convenient to design, place and take; due to the fact that the concave portion is formed in the top cover of the hub reduction gear, reduction of the weight of the whole reduction gear is facilitated.
Description
Technical field
The present invention relates to a kind of parts of wheel reductor, especially a kind of shell construction of wheel reductor.
Background technique
Wheel reductor is one of constituent element of automotive axle, can play and reduce the rotating speed that main deceleration biography is come, and increases the effect of gear end moment of torsion.Wheel reductor housing is the support accessory on wheel reductor, and on the one hand, wheel reductor housing plays a part to load other all parts of wheel reductor, and wheel reductor 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 wheel reductor, pass into and emit fluid, facilitate the shell construction that packs and take out and facilitate the wheel reductor of putting into and taking out of sun gear supporting into of sun gear.
According to technological scheme provided by the invention, the shell construction of described wheel reductor, it comprises cylindrical shell, bottom flange and top cover, in the bottom of cylindrical shell, be fixed with bottom flange, tip portion 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 ransaxle attachment hole, the first positioning hole and the second positioning hole, on the end face of top cover, be provided with depression, planet carrier attachment hole, sealing thread hole and bonnet mounting hole, and sealing thread hole is at the cylindrical near top cover, in depression, offer planet axis attachment hole.
The center of circle of the center of circle of the center of circle of described ransaxle attachment hole, the first positioning hole and the second positioning hole is on same circumference.
On the end face of top cover, evenly offer 3 ~ 6 depressions, in each depression, all offer planet axis attachment hole.
On the end face of the top cover between adjacent two depressions, be provided with described planet carrier attachment hole.
The center of circle in described sealing thread hole and the center of circle of bonnet mounting hole are on same circumference.
Sealing thread of the present invention hole is arranged on wheel reductor housing edge section, facilitates injection and the discharge of fluid; Wheel reductor housing boss design of the present invention, is convenient to heat radiation; Wheel reductor housing boss bore design, is convenient to the design of sun gear supporting and puts into and take out; On the top cover of wheel reductor, depression is set, is convenient to alleviate overall weight.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
The shell construction of this wheel reductor, it comprises cylindrical shell 1, bottom flange 2 and top cover 3, in the bottom of cylindrical shell 1, be fixed with bottom flange 2, tip portion at cylindrical shell 1 is connected with top cover 3, at the middle part of top cover 3, be provided with boss 4, on boss 4, offer endoporus 5, on bottom flange 2, offer ransaxle attachment hole 6, the first positioning hole 7 and the second positioning hole 8, on the end face of top cover 3, be provided with depression 9, planet carrier attachment hole 10, sealing thread hole 11 and bonnet mounting hole 12, and sealing thread hole 11 is at the cylindrical near top cover 3, in depression 9, offer planet axis attachment hole 13.
The center of circle of the center of circle of the center of circle of described ransaxle attachment hole 6, the first positioning hole 7 and the second positioning hole 8 is on same circumference.
On the end face of top cover 3, evenly offer 3 ~ 6 depressions 9, at each 9 interior planet axis attachment hole 13 that all offer that cave in.
On the end face of the top cover 3 between adjacent two depressions 9, be provided with described planet carrier attachment hole 10.
The center of circle in described sealing thread hole 11 and the center of circle of bonnet mounting hole 12 are on same circumference.
During wheel reductor work, in wheel reductor housing, pass into enough fluid, fluid is circulated in wheel reductor 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 wheel reductor housing edge section, can make fluid from then in hole, flow out smoothly, also can in wheel reductor 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 attachment hole 10, makes the overall structure of housing more reliable and more stable.
