Description
Technical field
The utility model belongs to mechanical transmission technical field, relates to a kind of speed reducer, particularly a kind of at a high speed than planet wheel multi-stage speed reducer.
Background technique
Retarder, as the general basic components of mechanical transmission, directly determines the ability of equipment, q&r.Planetary gear speed reducer due to its compact structure, volume is little, velocity ratio is large, is widely used in all trades and professions so far.But each model of traditional planetary gear speed reducer only has a speed ratio, very inconvenient under the working condition needing often change speed ratio.
Model utility content
The purpose of this utility model is to solve prior art Problems existing, provides a kind of rational in infrastructure, high speed that can be easy to use under needing often to change the working condition of speed ratio than planet wheel multi-stage speed reducer.
For achieving the above object and design technological scheme be such: the high speed provided comprises by sun gear tower-shaped gear group than planet wheel multi-stage speed reducer, planet wheel tower-shaped gear group, the front planetary gear train of front ring gear composition and by rear sun gear, rear planet wheel, the rear planetary gear train of rear ring gear composition, wherein, front ring gear and rear ring gear rigidly connected group of all-in-one-piece rotate ring gear, sun gear tower-shaped gear group forms by the pre-small post-large gear be contained on spline housing of arranging successively by n, n be greater than 1 positive integer, planet wheel tower-shaped gear group forms by the pre-large post-small gear be contained on front planet wheel shaft of arranging successively by n, the ring gear that front ring gear should engage with each gear mesh in planet wheel tower-shaped gear group respectively by the tower n of being distributed with, spline housing is sleeved on power input shaft slidably, when spline housing slides on input shaft, each gear in sun gear tower-shaped gear group can not side by side respectively with the corresponding gears meshing of on front planet wheel shaft, form the individual different reduction speed ratio of n, the rear end of power input shaft and the core wheel of rear sun gear are rigidly connected, the connection tie-rod for connecting pto＝power take-off is provided with at the core wheel place of rear planet wheel.
The preferred technical solution of the utility model is: sun gear tower-shaped gear group forms by the pre-small post-large gear be contained on spline housing of arranging successively by 2 ~ 10, planet wheel tower-shaped gear group forms by the pre-large post-small gear be contained on front planet wheel shaft of arranging successively by 2 ~ 10, front ring gear is distributed with 2 ~ 10 ring gears engaged with a corresponding gear in planet wheel tower-shaped gear group respectively by tower, when spline housing slides on input shaft, each gear in sun gear tower-shaped gear group can not side by side respectively with the corresponding gears meshing of on front planet wheel shaft, form 2 ~ 10 different reduction speed ratio.
Accompanying drawing explanation
Fig. 1 is the structural principle schematic diagram of the utility model specific embodiment.
In Fig. 1, the title of each number designation respectively: 1-power input shaft, 2-spline housing, 3-sun gear tower-shaped gear group, planet wheel shaft before 4-, 5-planet wheel tower-shaped gear group, 6-rotates ring gear, ring gear before 7-, ring gear after 8-, 9-rear sun gear, planet wheel after 10-, 11-connects tie-rod, 12-pto＝power take-off.
Embodiment
Below with reference to accompanying drawing, the utility model content is described further, but actual fabrication structure of the present utility model is not limited in following embodiment.
See accompanying drawing, high speed described in the utility model is made up of power input shaft 1, spline housing 2, sun gear tower-shaped gear group 3, front planet wheel shaft 4, planet wheel tower-shaped gear group 5, rotation ring gear 6, front ring gear 7, rear ring gear 8, rear sun gear 9, rear planet wheel 10, connection tie-rod 11, pto＝power take-off 12 etc. than planet wheel multi-stage speed reducer.Power input shaft 1 is equipped with slidably spline housing 2, spline housing 2 is provided with sun gear tower-shaped gear group 3, because sun gear tower-shaped gear group 3 and input shaft 1 are spline joints, so sun gear tower-shaped gear group 3 and rear sun gear 9 run-in synchronism.Planet wheel tower-shaped gear group 5 forms by the pre-large post-small gear be contained on front planet wheel shaft 4 of arranging successively by 3.Front planet wheel shaft 4 is equipped with fixed position rotating planet wheel tower-shaped gear group 5, and planet wheel tower-shaped gear group 5 forms by the pre-large post-small gear be contained on front planet wheel shaft 4 of arranging successively by 3.Front ring gear 7 is distributed with 3 ring gears 7 that should engage with each gear mesh in planet wheel tower-shaped gear group 5 respectively by tower.Front ring gear 7 and rear ring gear 8 rigidly connected groups of all-in-one-pieces rotate ring gear 6.Front ring gear 7 on rotation ring gear 6 and planet wheel tower-shaped gear group 5 engage always, and after the rear ring gear 8 rotated on ring gear 6 and rear sun gear 9 drive, planet wheel 10 drives pto＝power take-off 12 to operate by tie-rod 11.When spline housing 2 slides on input shaft 1, sun gear tower-shaped gear group 3 respectively with each group of gears meshing on front planet wheel shaft 4, form three kinds of different reduction speed ratio.
