Description
Technical field
The utility model belongs to mechanical transmission technical field, relates to a kind of speed reducer, and particularly a kind of oil specialized high-speed compares retarder.
Background technique
Retarder, as the general basic components of mechanical transmission, directly determines the ability of equipment, q&r.At present at the widely used mechanical reducer in petroleum operations field as oil field reducer of beam pumping unit etc., if in rated power situation, the retarder of a higher reduction speed ratio (such as 300: 1) will be become from the Design of Speed Reducer of a lower reduction speed ratio (such as 40: 1), just just must can reach designing requirement by the combination of multi-stage speed reducer, the quantity of the part such as gear and shaft member is needed also to be multiplied therebetween, this also just makes in the past traditional oil specialty retarder there is complex structure, volume is large, weight is large, high in cost of production problems.
Model utility content
The purpose of this utility model is to solve prior art Problems existing, provides a kind of oil specialized high-speed rational in infrastructure, easy to use than retarder, and its product when retarder number of components is constant, can reach the design of any reduction speed ratio.
For achieving the above object and adopt technical solution as described below.
A kind of oil specialized high-speed compares retarder, comprise by front sun gear, idle wheel, 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 suspension wheels, the core wheel of front sun gear and rear sun gear is rigidly connected by power input shaft, front sun gear is in transmission connection by idle wheel and front ring gear, rear sun gear is in transmission connection by rear planet wheel and rear ring gear, rear planet wheel core wheel is connected with pto＝power take-off, the change gear group be made up of bevel gear and break-in bevel gear is housed in the axostylus axostyle rear end of pto＝power take-off.
Technical solution of the present utility model also comprises: be provided with the connection tie-rod for connecting pto＝power take-off at the core wheel place of rear planet wheel, in the axostylus axostyle rear end connecting tie-rod, the change gear group be made up of bevel gear and break-in bevel gear is housed.
In above-mentioned oil specialized high-speed than in retarder, bevel gear and break-in bevel gear are spiral bevel gear.
Oil specialized high-speed described in the utility model is the extraordinary retarder combined by two groups of planetary gear train than retarder.In real work, when power input shaft operates, ring gear running before front sun gear is driven by idle wheel, planet wheel is then driven to move with the rear ring gear of front ring gear one, under rear sun gear and the common effect of rear ring gear, planet wheel drives pto＝power take-off to produce running, is namely controlled the movement velocity of front ring gear and rear ring gear by front planetary gear train, to reach the object of deceleration.If the wheel footpath of front sun gear is identical with the wheel footpath of rear sun gear, when the wheel footpath of front ring gear is identical with the wheel footpath of rear ring gear, although gear at different levels all engages normally, power input shaft also runs well, but the output speed of pto＝power take-off is zero, output torque is also zero.The change gear group be made up of bevel gear and break-in bevel gear is equipped with in the rear end connecting tie-rod at pto＝power take-off, and this structure can directly apply on the reducer of beam pumping unit of oil field.
In the utility model, the combination of two groups of planetary gear train always has the teeth parts of no more than 9, and these teeth parts, if any dimensional changes, just can design the retarder of multiple different speed ratio.That is, if in petroleum operations field, according to the reduction speed ratio required for production, as long as sun gear in change planetary gear train, the size of planet wheel (or idle wheel) and any one component of ring gear, make two groups, front and back planetary gear train running speed different, such power input shaft and power output shaft speed just have a variety of change, thus the retarder can designing different reduction speed ratio is (as 30: 1, 300: 1, 3000: 1, ) and moment of torsion, and unlike the retarder of other structure of related domain, to add large speed ratio or moment of torsion, just must increase the quantity of gear, structure is made to be tending towards complicated.Thus, under the condition that oil specialized high-speed described in the utility model uses at large speed ratio than retarder, than the existing like product in related domain advantageously, its structure is also more simple and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is fundamental diagram of the present utility model.
In figure, the title of each number designation respectively: 1-power input shaft, sun gear before 2-, 3-idle wheel, ring gear before 4-, ring gear after 5-, 6-planet wheel, 7-rear sun gear, 8-pto＝power take-off, 9-bevel gear, 10-break-in bevel gear.
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, oil specialized high-speed described in the utility model is made up of front sun gear 2, idle wheel 3, front ring gear 4, rear sun gear 7, planet wheel 6, rear ring gear 5, bevel gear 9, break-in bevel gear 10 etc. than retarder, wherein front sun gear 2, idle wheel 3, front ring gear 4 form front planetary gear train, rear sun gear 7, planet wheel 6, rear ring gear 5 form rear planetary gear train, front ring gear 4 and rear ring gear 5 rigidly connected groups of all-in-one-piece suspension wheels.On project organization, the core wheel of front sun gear 2 and rear sun gear 7 is rigidly connected by power input shaft (axis) 1, front sun gear 2 is in transmission connection by idle wheel 3 and front ring gear 4, rear sun gear 7 is in transmission connection with rear ring gear 7 by rear planet wheel 6, pto＝power take-off 8 is even contained in rear planet wheel 6 core wheel place, and the change gear group be made up of bevel gear 9 and break-in bevel gear 10 is equipped with in the rear end connecting tie-rod at pto＝power take-off 8.In work, before this High-Speed Ratio Reducer, planetary gear train controls the movement velocity of front ring gear 4 and rear ring gear 5, to reach the object of deceleration.According to aforesaid deceleration principle, current sun gear 2 and rear sun gear 7, idle wheel 3 and planet wheel 6 and front ring gear 4 all identical with the size often organizing gear in these three groups of gears of rear ring gear 5 time, then the power input shaft 1 of retarder is under any rotating speed, and the rotating speed of pto＝power take-off 8 is all zero.As long as the size of any one group of gear (sun gear, planet wheel, ring gear), makes the running speed of front planet wheel and rear planetary gear train different, namely can design the retarder of different reduction speed ratio in change planetary gear train.
