Abstract
The utility model is the improvement of a variable speed force driving system in industries such as automobiles, hoisting and transportation, machine tools, etc., and to be precise, a spherical gear transmission is utilized to realize the possibility of stepless variable speed. The utility model is made by connecting in series a differential gear train, a spherical gear speed regulating wheel train, an epicyclic gear speed regulating wheel train in turn, and the connection between the spherical gear speed regulating wheel train and a component velocity wheel is realized through sliding slices inserted in the component velocity wheel. Compared with the original step variable speed technique after the realization, the utility model has the advantages of small possibility of damage, low cost, extended mechanical service life, etc.
Description
The utility model is the improvement to the speed change actuating system in automobile industry, lifting carrier, the machine industry, exactly is a kind of improvement to the gear type step change device of former machinery.
In present automobile, lifting transportation and machine industry, what its speed change actuating system used often is the gear type speed change gear.This device often has following shortcoming: 1, can not realize stepless change; 2, speed change program complexity; 3, there is carelessness that gear is damaged in the speed-change process slightly.So the speed change force-transmitting device preferably uses stepless speed changes devices.But because can realize that infinite variable speed kind has the stepless change of hydraudynamic drive formula, friction type stepless change, direct current stepless change etc. at present, these method for changing speed often all can not directly apply to above-mentioned industry, so can only look for way on the gear type drive transmission device.
The purpose of this utility model is at the problems referred to above, for the user provides a kind of spherical gear transmission type stepless speed changes devices.
The purpose of this utility model is achieved in that this device is made up of differential gear train, spherical gear speed governing train and planet cyclic gear train, and its technological points is: differential gear train, spherical gear speed governing train, planetary pinion epicyclic gear train are connected in series in turn; In spherical gear speed governing train, be shaped on annular cavity on the speed separation wheel, and interior dress metallic grit, its outside is shaped on annular slide track, and communicates with annular cavity; Slide plate directly sticks with on annular slide track, and can slide relative under the effect of external force; Be bearing hinge connection between spherical gear and the speed-regulating handle, with slide plate in the postrotational speed separation wheel be to be connected with a joggle; Be hinged between speed-regulating handle and frame.
When the spherical gear speed control system is installed, the geometric condition that spherical gear and two speed separation wheels should satisfy is: the intersection point of the tangent line of two speed separation wheels and spherical gear contact points should overlap with the intersection point of two speed separation wheel lines of centres and the speed-regulating handle center line when the vertical speed separation wheel link position.
After the utility model is realized, can realize when driving just changeing, zero change, the stepless change problem of Umklapp process, and then simplified the driver operation program, in speed-change process, just can realize speed change without stepping on clutch.In addition, owing to saved the process of putting into gear,, promptly avoided recurrent gear to damage phenomenon, the life-span of having improved gearbox so avoided the impact between gear and gear.The utility model if can be widely used in automobile, lathe and lifting carrier, creates bigger benefit with can be society.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model overall structure figure;
Fig. 2 is the utility model overall structure sketch;
Fig. 3 is the relative position figure of spherical gear and speed separation wheel in the utility model speed control system.Among the figure, 1-input shaft, 2-gear, 3-gear, 4-outer shroud, 5-pusher dog clutch, 6-planetary bevel gear, 7-umbrella gear, 8-umbrella gear, 9-commutation umbrella gear, 10-commutation umbrella gear, 11-commutation umbrella gear, 12-central shaft, 13-slide plate, 14-hemisphere speed regulation gear, 15-speed separation wheel, 16-speed separation wheel, 17-sun gear, 18-planetary pinion, 19-central gear, 20-planetary pinion reel, 21-output shaft, 22-speed-regulating handle, 23-metallic grit, the 24-centre of sphere.
As shown in Figure 2, gear 6,7,8,9 forms the differential gear train of this utility model; Gear 10,11, differential gear 15,16, slide plate 13, spherical gear 14 forms the speed governing train of this utility model; Gear 17,18,19 and toothed disc 20 form these novel planet cyclic gear trains. Its operation principle is as follows: engine power by power shaft 1 direct driven gear 2,3 and outer shroud 4 rotate, pusher dog clutch 5 is connected in differential gear train, when this is not to be subjected under the condition of external force, planetary bevel gear 6 is accepted will mesh together with bevel gear 7,8 after the power of engine and is Integral synchronous rotation, i.e. n6＝n
7＝n
8 When differential gear train is accepted external force, when namely differential gear 15,16 was subjected to the restriction of not Constant Linear Velocity of hemisphere governor gear 14, planetary bevel gear 6 just began spinning motion, made the bevel gear 7 and 8 can not synchronous rotary, namely speed was resolved into n7≠n
8Two kinds of speed. Wherein a kind of speed is to pass to the central gear 19 of planet circular system by bevel gear 7 by central shaft 12, and another kind of speed then passes to 17 of planet circular system by bevel gear 8 by tumbler gear 9,10,11. These two kinds of velocities of rotation finally synthesize a kind of speed by planetary gear 18, by planetary gear reel 20 and output shaft 21 outputs.
As shown in Figure 3: the operation principle of stepless speed regulation is as follows: because differential gear 15,16 rotates, its centrifugal force makes the metallic grit in the differential gear move to outer rim, the transverse component of its centrifugal force will promote slide plate to the motion of spherical gear direction, and consequently slide plate and spherical gear mesh and jointly rotate with differential gear. When R1=R2, two The rotating speed of differential gear equates, when stirring speed adjusting lever 22, if R2 ≠ R1 then the speed of two differential gears is also unequal, the variation of its rule will change along with the diverse location of speed control rod, because gear 14 is spherical, its facewidth is uniformly from large to small, and it also is uniformly that the revolution that fast differential gear 16 forms changes, and then to make last velocity variations synthetic in epicyclic train also be uniform. Therefore realized infinite variable speed hope.
