Less effort speed changer

Abstract

The invention relates to a less effort speed changer, and refers to a less effort device capable of accelerating and decelerating; the technical scheme is that a pressure device is arranged, so besides engaging acting force between an external gear 2 and an annular internal gear, a rotating acting force is also applied between the two, so rotation can be more labor saving; a main gear 1 can synchronously rotate with the annular internal gear; different drive relations and diameters are arranged between the main gear 1 and a pinion 2 and between a main gear 2 and a pinion 3; if the main gear 1 rotate for one circle, the rotating lap speed of the pinion 3 can be greatly enlarged or decreased; when the speed changes, the annular internal gear uses less power force. The speed changer uses a lever principle to continually add acting force in the rotating direction, thus saving labor; the gears are arranged, so speed can be fast changed under same power force.

Description

technical field [0001] The invention relates to a device that saves labor and can accelerate or decelerate. technical background [0002] In the existing riding tools, when accelerating or exerting force on the roller, it usually uses its own weight to make it run quickly, such as riding a tricycle or bicycle, which is very laborious and unsafe. In tricycles or bicycles and other means of transport, its operation is all to drive the pinion to rotate through a large gear, and then the pinion drives the wheel to rotate. Its structure is simple, but it cannot achieve the purpose of labor saving. Contents of the invention [0003] The purpose of the present invention is to solve the problems of the prior art and provide a labor-saving transmission that can both accelerate or decelerate. The accelerator continuously adds force in the direction of rotation through the principle of leverage to achieve the purpose of labor-saving, and through the gear The unique design enables it...

[0002] In the existing riding tools, when accelerating or applying force to the roller, it usually uses its own weight to make it run quickly, such as riding a tricycle or bicycle, which is very laborious and not safe.

In tricycles, bicycles and other means of transportation, a large gear drives the pinion to rotate, and then the pinion drives the wheel to rotate. Its structure is simple, but it cannot achieve the purpose of saving labor.
