Abstract
The invention provides a kind of simple in construction 1：2 or 2：1 speed change gear, two runners are linked by track, one of them small runner carries multiple same ambulatory claws, another great wheel is with the cross one another rectilinear orbit with quantity identical with ambulatory claw, each same ambulatory claw corresponds to straight line track, and along this track motion, 180 degree is often rotated with ambulatory claw, corresponding 90 degree of orbit rotation, so as to realize the great wheel and the small runner 1：2 rotating ratio.The mode of track can be sliding groove structure or magnetic orbit structure.The present invention can be used with multistage-combination, be widely used in various mechanical driving devices.
Description
Technical field
The present invention relates to a kind of speed change gear.
Background technology
Existing speed change gear species is various, mainly realizes that Gear Processing is complicated by various gears or belt pulley combination,
Belt service life is limited.
The content of the invention
The purpose of the present invention is to overcome above-mentioned deficiency, there is provided a kind of simple speed change gear.
The technical solution adopted by the present invention is：
Two runners are linked by track, and one of them small runner carries multiple same ambulatory claws, another great wheel carry with it is synchronous
The cross one another rectilinear orbit of the identical quantity of pawl, each same ambulatory claw correspond to straight line track, along this track motion,
180 degree is often rotated with ambulatory claw, corresponding 90 degree of orbit rotation, so as to realize that the rotating ratio of the great wheel and the small runner is
1：2.
The mode of track can be sliding groove structure or magnetic orbit structure.
The effect of the track is to constrain or guides the movement locus of the same ambulatory claw；In addition, prior art
Adoptable chute or track structure are numerous, do not enumerate.
Beneficial effect：
The invention provides a kind of simple in construction 1：2 or 2：1 speed change gear, it can be used, be widely used in multistage-combination
Various mechanical driving devices.
Brief description of the drawings
Fig. 1 is the front view of embodiment
Fig. 2 is the side view of embodiment
Embodiment
As shown in Figure 1 and Figure 2, a kind of speed change gear of two tracks of sliding groove structure, including big turn are present embodiments provided
Take turns 1, small runner 2, with ambulatory claw 3 and pedestal 4.
The great wheel 1 and the small runner 2 are flexibly connected with the pedestal 4 respectively, can be rotated with opposite base 4；Institute
State the rotating shaft of great wheel 1 and the shaft parallel of the small runner 2, there are 2 to be arranged symmetrically along spindle central on the small runner 2
The same ambulatory claw 3, the axle center distance of the great wheel 1 and the small runner 2 are equal to the same ambulatory claw 3 on the small runner 2
Axle center has on the great wheel 1 two to be handed over by the orthogonal straight-line groove in axle center to the distance in the axle center of the small runner 2
Fork forms orbiting vane, and 2 same ambulatory claws 3 are respectively embedded into orbital motion in this two tracks, in great wheel 1 and small runner
In 2 rotation processes, the same ambulatory claw 3 moves along corresponding rectilinear orbit, make the great wheel 1 and the small runner 2 with
1：2 rotating ratio rotates.
It is described above, only it is the better embodiment of the present invention, any restrictions is not done to the present invention, it is every according to this hair
Any modification, change and the equivalent structure change that bright essence is made to embodiment of above, still fall within the technology of the present invention
Within protection domain.
