Abstract
A speed change gear with non-closed chains and a function of cone-assisted enlargement and reduction is provided with a 'non-closed chain combination'. A cone moves up and down to mutually act with chain boots, so that the diameter of the chains is enlarged or reduced regularly, the number of holes of the chain combination is increased or decreased, and speed of a double gear tightly meshing with the chains is increased or decreased. The speed change gear with non-closed chains and the function of cone-assisted enlargement and reduction can be used on an existing car or motorcycle to achieve infinitely variable gear speed, and the shortages that existing speed change gears are high in weight, large in size and complex in structure and are driven by friction are overcome.
Description
The present invention relates to " cone scalable not closed chain speed change gear ", is that the present inventor is about the innovation and creation proposed on February 14th, 2012 " one is closed gear combined tooth number change device not " by name; Application number is 201210032103.7; The applying date is the basis applied for a patent on February 14th, 2012 is transformed form.What " one is closed gear combined tooth number change device not " adopted is erose not closed gear assembly, eccentric inertial force is produced with regard to disequilibrium during rotation, have impact on high speed to rotate, disadvantage that Here it is " one is closed gear combined tooth number change device not ".
" cone scalable not closed chain speed change gear " that this name proposes just solves above shortcoming, original " not closed gear combined tooth " is made into " not closed chain combination " steady in the running, substantially increases rotational speed.
" cone scalable not closed chain speed change gear " provided by the present invention, its for a kind of by upper not closed chain, under the not mechanism that forms of closed chain, chain boots pin, chain termination, draught spring, chain guide post, guide-track groove, cone, Double-gear, up and down gear shaft, up and down gear shaft guide rail piston framework.Structure characteristic of the present invention and object is further illustrated below in conjunction with accompanying drawing.
Brief Description Of Drawings:
Fig. 1 is the basic structure schematic diagram of " cone scalable not closed chain water caltrop speed variator " provided by the present invention
Fig. 2, Fig. 3, Fig. 4 be " cone scalable not closed chain speed change gear " provided by the present invention scalable chain schematic diagram,
Please see Figure 1, shown in Fig. 2, Fig. 3, Fig. 4, it have a cone 10 mainly in framework 30, be with above two not closed chain 1 and 4 strained by draught spring 5 and 33, be wrapped in cone 10, and and Double-gear 23 be engaged; On not closed chain 1 with under closed chain 4 is not overlapping, form a circle unitary closed chain; Not closed chain 1 and not closed chain 4 corresponding change formation one can enclose overall overlapping closed chain hole count when cone about 10 vibration; Rotate cone 10, Double-gear 23 rotates thereupon, by upper vibration axle 11 and lower vibration axle 13 Power output.When cone 10, upper vibration axle 11 and lower vibration axle 13 are up pushed away by upper vibration axis hole 12, lower vibration bearing hole 14, boots pin 7,8 below upper chain 1, lower chain 4 expands diameter under the effect progressively of cone inclined-plane, makes the hole count of two inc chain assembleds increase and change with Double-gear tooth ratio and makes Double-gear add rotating speed; When cone 10, upper vibration axle 11 and lower vibration axle 13 are up shifted onto framework 30 top, the diameter of chain 1 and chain 4 is expanded as maximum by cone 10, chain 1 and chain 4 combine hole count to be increased at most, and change maximum with Double-gear tooth ratio, the revolution that Double-gear is increased is maximum.Otherwise, cone 10, upper vibration axle 11 and lower vibration axle 13 by upper vibration axis hole 12, lower vibration bearing hole 14 from framework 30 top depress time, boots pin 7,8 below upper chain 1, lower chain 4 reduces diameter under the effect progressively of cone 10 inclined-plane, make the hole count of two inc chain assembleds reduce and change with Double-gear tooth ratio, make Double-gear decrease rotating speed; When cone 10, upper vibration axle 11 and lower vibration axle 13 are down shifted onto bottom framework 30, the diameter of chain 1 and chain 4 is condensed to minimum by cone 10, it is minimum that chain 1 and chain 4 combine hole count reduction, and change minimum with Double-gear gear ratio example, the revolution that Double-gear is reduced is minimum.
Do not move left and right when serving cone about 10 vibration in the guide-track groove 9,34 of the guide rail column be not fixedly connected with below closed chain 1,4 in above mechanical motion in cone 10, do not allow two not wiggly effects of closed chain 1,4 all the time;
Upper chain baffle plate 15 (1), 16 (2), 17 (3), 18 (4) Tou be located in above mechanical motion on framework 30 plays the effect not allowing chain 1 and 4 move up and down;
In above mechanical motion, be located at guide rail piston 24 and 27 side-to-side movement in gear shaft guide-track groove on bidentate wheel shaft, groove inner spring allows Double-gear 23 and upper chain 1 and lower chain 4 close contact all the time.
Of the present invention execute example one of: should " cone scalable not closed chain speed change gear " for speed-changing mechanism of motorcycle, can realize from sprocket wheel stepless change, slewing range is wide; Experiment proves that this device can change riding speed arbitrarily; Slewing range greatly and easily operate; Grade ability is strong; Speed-raising is fast; Save the advantages such as fuel oil.
