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 scalable not closed chain of cone speed change gear

The present invention relates to " the scalable not closed chain of cone speed change gear ", is that the inventor is about the innovation and creation that proposed on February 14th, 2012 " a kind of not closed Gear combination becomes number of teeth device " by name; Application number is 201210032103.7; The applying date is to transform on the principle basis of applying for a patent on February 14th, 2012 to form." a kind of not closed Gear combination becomes number of teeth device " what adopt is erose not closed gear assembly; Produce eccentric inertial force during rotation with regard to disequilibrium; Influenced high-speed rotation, disadvantage that Here it is " a kind of not closed Gear combination becomes number of teeth device ".

" the scalable not closed chain of cone speed change gear " that this name proposed just solved above shortcoming, and it is steady in the running to make " not closed chain combination " to original " not closed Gear combination " into, has improved rotational speed greatly.

" the scalable not closed chain of cone speed change gear " provided by the present invention, its for a kind of by last not closed chain, down not closed chain, chain boots pin, chain termination, draught spring, chain guide post, guide-track groove, cone, bidentate wheel, gear shaft, the mechanism that formed of gear shaft guide rail piston framework up and down up and down.Further specify structure characteristic of the present invention and purpose below in conjunction with accompanying drawing.

Brief Description Of Drawings:

Fig. 1 is the basic structure schematic representation of " the scalable not closed chain of cone water caltrop quick-mounting is put " provided by the present invention

Fig. 2, Fig. 3, Fig. 4 be " the scalable not closed chain of cone speed change gear " provided by the present invention scalable chain schematic representation,

Please see Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, it mainly is in framework 30, and a cone 10 is arranged, be with above two not closed chain 1 and 4 by draught spring 5 and 33 the tension, be wrapped on the cone 10, and with bidentate take turns 23 interlocks; On closed chain 1 form a circle unitary closed chain with closed chain 4 is not overlapping down; Not closed chain 1 and not closed chain 4 can go here and there up and down in cone 10 and can corresponding change form the whole overlapping closed chain hole count of a circle when moving; Rotate cone 10, bidentate wheel 23 rotates thereupon, through last string moving axis 11 and string moving axis 13 power output down.Cone 10, on go here and there moving axis 11 and down string moving axis 13 through last string moving axis hole 12, go here and there dynamic bearing hole 14 when up pushing away down; Boots pin 7,8 below last chain 1, the lower chain 4 have enlarged diameter under the effect progressively of cone inclined-plane, the hole count of two inc chains combinations is increased and change with bidentate tooth number ratio to make the bidentate wheel increase rotating speed; Cone 10, on go here and there moving axis 11 and when down string moving axis 13 is up shifted framework 30 tops onto; The diameter of chain 1 and chain 4 is expanded to maximum by cone 10; Chain 1 increases at most with chain 4 combination hole counts, and with the bidentate tooth number ratio maximum that changes, the revolution that the bidentate wheel is increased is maximum.Otherwise; Cone 10, on go here and there moving axis 11 and down string moving axis 13 through last string moving axis hole 12, go here and there dynamic bearing hole 14 when framework 30 tops down push away down; Boots pin 7,8 below last chain 1, the lower chain 4 have dwindled diameter under the effect progressively of cone 10 inclined-planes; The hole count that two inc chains are made up reduces and changes with bidentate tooth number ratio, makes the bidentate wheel reduce rotating speed; Cone 10, on go here and there moving axis 11 and when down string moving axis 13 is down shifted framework 30 bottoms onto; The diameter of chain 1 and chain 4 is condensed to minimum by cone 10; Chain 1 is minimum with chain 4 combination hole counts reductions, and with the bidentate wheel gear number of teeth ratio minimum that changes, the revolution that the bidentate wheel is reduced is minimum.

In above mechanical motion, do not play cone 10 in closed chain 1, the guide-track groove 9,34 of guide rail column on cone 10 that be fixedly connected below 4 and go here and there when moving not move left and right up and down, do not allowed two not closed chain 1,4 wiggly effects all the time;

In the above mechanical movement of the frame 30 provided in the upper plate chain 15 (1), 16 (2), 17 (3), 18 (4) is to play Tou keep moving up and down the chain 1 and 4, the role;

In above mechanical motion, be located at

guide rail piston

24 and 27 side-to-side movements in the gear shaft guide-track groove on the bidentate wheel shaft, the groove inner spring lets bidentate wheel 23 closely contact with lower chain 4 with last chain 1 all the time.

One of example of executing of the present invention: should " the scalable not closed chain of cone speed change gear " be used for the motorcycle gear, and can realize that slewing range was wide from the sprocket wheel stepless change; This device of experiment proof can change riding speed arbitrarily; Big and the operation easily of slewing range; Grade ability is strong; Speed-raising is fast; Save advantages such as fuel oil.
