Embodiment 1

[0060] a transmission such as image 3 As shown, it includes a driving lever 5 and a driven lever 6, and one end of the driven lever 6 is connected with a one-way transmission, and the one-way transmission includes an output shaft 7 fixedly connected to the driven lever 6 and a fixed connection on the output shaft 7. The one-way transmission part adopts one-way bearing 8 (such as the one-way bearing 8 of CSK series), and when the driven lever 6 rotates in one direction around the output shaft 7, the one-way bearing 8 can be driven by the output shaft 7 as a whole Rotate, when the driven lever 6 rotates in another direction, the outer ring of the one-way bearing 8 does not rotate. , when the driven lever 6 does reciprocating swinging motion, it can drive the transmission part to rotate in one direction.

[0061] The end of the driven lever 6 far away from the output shaft 7 is connected with a slider, and the end of the active lever 5 close to the driven lever 6 is provided wi...

Embodiment 2

[0071] A speed changer, the difference from Embodiment 1 is that, as Figure 7 and Figure 8 As shown, the front splicing rod 62 is threadedly connected with the rear splicing rod 63, the length of the driven lever 6 can be rotatably adjusted, and after the length is adjusted, the length of the driven lever 6 is not easy to change during use, and the driven lever 6 The length can be maintained more stably, improving the working reliability of the transmission.

Embodiment 3

[0073] A speed changer, the difference from Embodiment 1 is that, as Figure 9 and Figure 10 As shown, the driven lever 6 also includes a length adjustment rod 64, and the two ends of the length adjustment rod 64 are all provided with threads and are threadedly connected with the front splicing rod 62 and the rear splicing rod 63 respectively by threads, and the threads at the two ends of the length adjustment rod 64 are threaded. On the contrary, when the length adjustment lever 64 is rotated in one direction, the front splicing lever 62 and the rear splicing lever 63 can be made to approach or move away from each other, thereby realizing the function of adjusting the length of the driven lever 6 .

[0074] In this embodiment, without disassembling the driven lever 6, the length adjusting rod 64 can be rotated to adjust the length of the driven lever 6, which is more convenient to adjust.

Abstract

The invention discloses a transmission which comprises a driven lever, a driving lever and a one-way transmission device. The one-way transmission device is in transmission connection with one end ofthe driven lever, the other end of the driven lever is in sliding connection with the driving lever, a front fixed shaft is rotationally connected to the driving lever, and the driving lever can drivethe driven lever to rotate around the one-way transmission device when rotating around a front fixing shaft; the length of a force arm of the driven lever is adjustable, the length of the driven lever is adjusted, and therefore the transmission ratio of the driven lever to the driving lever can be adjusted; through multi-stage lever transmission, the swing angle of the driving lever can be reduced, the rotating angle is within the labor-saving zone, and the force saving effect can be achieved; and the driving lever and the driven lever are in threaded connection through a length adjusting rod, the length adjusting continuity can be improved, and infinitely variable speed can be achieved.

Description

technical field [0001] The invention relates to the technical field of speed regulation, in particular to a transmission. Background technique [0002] A transmission is a device used to change the transmission ratio between the input shaft and the output shaft, and can be used in equipment or devices that require speed adjustment such as automobiles, bicycles, and machine tools. [0003] For example, the Chinese invention authorization text whose notification number is CN102606426B discloses a stepping fitness generator. Such as figure 1 As shown, it includes a body, a power generating mechanism and a transmission mechanism 1, and the transmission mechanism 1 includes a driven shaft 11, an energy storage wheel 12, and a left and right transmission mechanism 13 and a right transmission mechanism 14 arranged symmetrically; Pedal bar 131, left main shaft 132, left driving wheel 133, left transmission chain 134, left driven wheel 135 and left one-way bearing 136, right transm...
