Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of the utility model rather than whole
Embodiment.
With reference to Fig. 1-2, a kind of mechanical gear of variable-ratio, including casing 1, in casing 1, it has been horizontally disposed with splined shaft 9,
One end of splined shaft 9 is run through the side wall of casing 1 and is extended to outside casing 1, and the other end of splined shaft 9 is sheathed successively from left to right
There are the 3rd gear 7, sleeve 6 and the 4th gear 8, the both sides of sleeve 6 are provided with can be engaged with the 3rd gear 7, the 4th gear 8
The gear teeth, sleeve 6 can follow splined shaft 9 to rotate it is also possible to move left and right on splined shaft 9, and sleeve 6 is connected with gear lever 10,
Gear lever 10 extends to outside casing 1 away from one end of sleeve 6, and gear lever 10 arranges rubber sleeve, rubber with the junction of casing 1
Gum cover plays the role of protection and damping, is easy to use, casing 1 top offers multiple louvres, and gear rotates for a long time and can produce
Raw substantial amounts of heat, louvre contributes to radiating.
3rd gear 7, the bottom of the 4th gear 8 correspond to engagement respectively and are connected with first gear 3, second gear 4, the first tooth
Wheel 3, second gear 4 are all set on jackshaft 5, and jackshaft 5 is arranged with the first drive 2 away from one end of second gear 4, the
One drive 2 engagement is connected with the second drive 11, and the second drive 11 engagement is connected with the 3rd drive 12, the 3rd drive
