Abstract
The utility model relates to a frame of a reduction gear. The frame is connected inside a reduction gear box of the reduction gear and comprises a planet pinion shaft cavity and a multi-point parallel shaft cavity, an outer sun wheel supporting hole is formed on the outer side wall of the planet pinion shaft cavity, an inner sun wheel supporting hole which is coaxial with the outer sun wheel supporting hole is formed on the inner side wall of the planet pinion shaft cavity, a plurality of groups of corresponding inner planet pinion shaft supporting holes and outer planet pinion shaft supporting holes are distributed along both the circumferential directions of the inner side wall and the outer side wall of the planet pinion shaft cavity, a plurality of groups of corresponding inner parallel shaft supporting holes and outer parallel shaft supporting holes are distributed along both the circumferential directions of the inner side wall and the outer side wall of the parallel shaft cavity, and the axes of the inner planet pinion shaft supporting holes and the outer planet pinion shaft supporting holes are parallel to those of the inner parallel shaft supporting holes and the outer parallel shaft supporting holes. The frame of the reduction gear is simple and compact in overall structure, easy to manufacture and low in cost, occupies small space due to the fact that a planet pinion shaft mechanism and a multi-point parallel shaft mechanism are arranged in a speed reduction device, and can effectively improve assembly and transmission accuracy of every shaft and prolong the service lives of transmission shafts due to the fact that the transmission shafts are arranged in the frame which is of an integral structure.
Description
Technical field
The utility model relates to a kind of supporting structure, is a kind of brave headstock for the supporting speed reducer driving shaft specifically.
Background technique
Planetary Gear Transmission is compared with the ordinary gear transmission, and outstanding feature is: it can carry out power dividing when transferring power; Simultaneously, its input shaft and output shaft have alignment, and namely output shaft and input shaft all are arranged on same main axis.So Planetary Gear Transmission now is used for replacing the ordinary gear transmission by people, and as the retarder in various machine driven systems, speed increaser and speed change gear.Especially for those want that cube is little, quality is little, the gear drive of compact structure and high aeroengine, lifting transportation, petrochemical industry and the weapons etc. of transmission efficiency and need the automobile of differential mechanism and the gear drive of the vehicle such as tank, Planetary Gear Transmission has obtained using more and more widely.Comprise simultaneously planetary gear mechanism and shunting parallel axes mechanism in existing apparatus, its planet carrier and parallel axes supporting structure are separate, transmission between the two is stable, precision is low, and both independently make, assemble loaded down with trivial details, cost is high, both are installed on respectively and take up room in device greatly, cause the device overall volume to increase, the installing space of device is limited to.
Summary of the invention
For deficiency of the prior art, the utility model provide a kind of simple in structure, compact, easy to process, cost is low, volume is little, takes up room little, is conducive to improve the speed reducer tiger headstock of the stable and quality of fit of transmission.
The technical solution adopted in the utility model is: a kind of speed reducer tiger headstock, the tiger headstock is connected in box body of speed reducer, its technical characterstic is the planet chamber axocoel parallel with multiple spot that the described brave headstock comprises disjunctor, the outer side wall in described planet chamber is provided with outer sun gear bearing hole, the madial wall in planet chamber is provided with the interior sun gear bearing hole coaxial with outer sun gear bearing hole, and on the inside and outside sidewall in planet chamber, circumferencial direction is laid with many groups corresponding inside and outside planet axis bearing hole mutually; On the inside and outside sidewall of the parallel axocoel of described multiple spot, circumferencial direction is evenly equipped with many groups inside and outside parallel axes bearing hole of correspondence mutually; The axially bored line of described inside and outside star axle bearing hole is parallel with the axially bored line of inside and outside parallel axes bearing hole.
Further, the axially bored line of the inside and outside parallel axes bearing hole of the mutual correspondence of described many groups overlaps with axially bored lines outer, two sun gear bearing hole.
Further, described planet chamber madial wall axocoel madial wall parallel with multiple spot overlaps.
Again further, any wall of the inside and outside sidewall of the parallel axocoel of described multiple spot and periphery ring wall or many walls are provided with oil inlet hole.
When this tiger headstock uses, the sun gear cross-under of epicyclic transmission mechanism is supported in the inside and outside sun gear bearing hole in planet chamber, a plurality of planet axis cross-under respectively are supported in many groups of corresponding inside and outside planet axis bearing hole in the planet chamber, planetary pinion cross-under planet axis engagement sun gear; Many parallel axes of multiple spot parallel axes mechanism cross-under respectively are supported in many groups of interior corresponding inside and outside parallel axes bearing hole of the parallel axocoel of multiple spot, many parallel axes circumferencial directions engagement sun gears; Planet chamber axocoel linking body structure parallel with multiple spot, overall structure is simple, compact, processing and fabricating is convenient, cost is low, epicyclic transmission mechanism and multiple spot parallel axes mechanism be installed on take up room in speed reducer little, and each cardan-shaft suspension is in the brave headstock of integrative-structure, supporting, transmission are stable, can effectively improve each axle assembling, transmission accuracy, extend transmission working life.
