Embodiment Construction

[0054] Specific embodiments of the present invention such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 11 Shown:

[0055] The specific structure of its core part is: through the cooperation of a special wedge-shaped sliding vane warehouse 14 and the wedge-shaped movable tooth unit beam 3, use its axial movement to obtain the circumferential tangential displacement, so as to adjust the circumferential tangential displacement of the sliding vane. To eliminate the meshing gap between the slide plate and the sprocket. For its enlarged view, see: Figure 11 ;

[0056] The detailed structure of relevant parts and components of the present invention and the assembly relationship with the transmission assembly are referred to: figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 .

[0057] As shown in the figure: the slide 15 is placed in the wedge-shaped slide bin 14, and the wedge-shaped slid...

Abstract

The invention provides a mechanism for eliminating engaging backlash between oscillating teeth and sliding sheets as well as a design method capable of prolonging the life of engaging teeth, and belongs to the technical fields of mechanical transmission as well as continuously variable transmission design and manufacturing. The mechanism and the design method provided by the invention are regardedas improved technologies based on Patent 200580039668.6, and Patent 200580039668.6 records an engaging-type continuously variable transmission which has the following characteristics: the engaging-type stepless speed changing function is created depending on the sliding sheets and the oscillating teeth, the defect that a conventional continuously variable transmission depends on friction transmission is overcome, and the characteristics of high power and high efficiency are achieved; however, due to the certain thicknesses of the sliding sheets, the no-backlash engaging effect cannot be guaranteed in any states when the oscillating teeth formed by combining the sliding sheets are engaged with chain teeth; and accordingly, rotating speed pulsation and torque pulsation are generated. Through the mechanism for eliminating the engaging backlash between the oscillating teeth and the sliding sheets as well as the design method capable of prolonging the life of the engaging teeth, the aboveproblem about rotating speed pulsation and torque pulsation can be effectively solved, the no-load engaging-in and no-load engaging-out effect can be achieved, the transmission precision can be improved, the life can be prolonged, and the metal chain, conical disc and oscillating tooth abrasion automatic-compensation function can also be achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission and stepless transmission design and manufacture. Background technique [0002] The patented technology "Slide Deformation Teeth Stepless Mesh Movable Gear" Patent No. 200580039668.6, records a kind of meshing continuously variable transmission. The transmission relies on the disadvantage of friction transmission, and has the characteristics of high power and high efficiency. However, since the slide itself has a certain thickness, when the movable teeth formed by the combination mesh with the chain teeth, it cannot be guaranteed to achieve backlash-free meshing in any state. Moreover, since the movable teeth are composed of several slides, , so there will be a certain elastic deformation when the torque is loaded, which will further increase the meshing backlash. This results in rotational speed pulsation and torque pulsation. And shorten the life of movable tooth transmission....
