Embodiment Construction

[0017] Such as figure 1 As shown, the present invention is a continuously variable gear with a variable number of teeth. When working, the power that needs to be shifted is connected to the input shaft (1) through a coupling and input, and the input shaft (1) and the cage (2) are fixedly connected to drive the planets. The bevel gear (3) makes each planetary bevel gear (3) revolve around the central axis with the input shaft (1) on the one hand, and at the same time rotate itself around the bisecting axis of the cage. The planetary motion synthesized by the two passes through the planetary cone The gear (3) drives the driven bevel gear (10) to transmit the power to the output shaft; if it is a variable speed vehicle, connect the speed regulating screw and the screw of the handwheel (9) through a certain mechanism to make it conform to ergonomics The principle is to consider the convenience of the driver's operation and to bring out the speed change function of the present inve...

Abstract

The invention relates to a mechanical stepless transmission, in particular to a pure gear engaged mechanical stepless transmission. As shown in figure 1, power drives planet bevel gears (3) via an input shaft (1) and a retainer (2) so that each planet bevel gear performs revolution around a central axial line along with the input shaft (1) on the one hand, and, on the other hand, itself rotates around the equally-divided hole axial line of the retainer (2), and planet movement resulting from revolution and rotation drives a driven bevel gear (11) via a driven planet bevel gear (10) to transmit the power to an output shaft (12). In speed variation, a speed change gear (6) makes pure rolling movement on a cylindrical surface (formed of the generatrix of the outermost planet bevel gear of several uniformly-distributed planet bevel gears), to realize speed variation. The mechanical stepless transmission provided by the invention has the advantages of high transmission power and efficiency, simple structure and low cost. For an automobile, improvement on transmission efficiency means fuel saving, and the engine works under an ideal condition to achieve full fuel combustion and clean emission and reduce pollution to environment.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a mechanical stepless transmission with pure gear meshing. Background technique [0002] The continuously variable transmission realized by mechanism or purely mechanical components is called mechanical continuously variable transmission. At present, there are mainly two transmission forms: friction type and pulsation type. In the basic theory of mechanical design, the basic forms of mechanical transmission include friction transmission, gear transmission, belt transmission, chain transmission and mechanism transmission. The transmission mode of the friction continuously variable transmission is formed by the evolution and combination of these basic transmission modes, and the pulse type continuously variable transmission is formed by the combination of mechanisms. [0003] All gear CVT designers are aware that friction transmission has inherent insurmountable defects, and...
