Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The non-circular gear speed change transmission mechanism of the present invention has two characteristics: one is that it can change speed without stopping, that is, when changing the meshing transmission ratio of the driving wheel and the driven wheel, there is no need for the gear to stop running, and the original speed can be maintained. Under the premise, gear shifting is realized, thereby improving the operating efficiency of the mechanism; second, the speed change transmission mechanism is not limited to the transformation of one or two gears, and the mechanism can be used to realize the transformation of multi-stage transmission ratios.

[0024] see Figure 1 to Figure 4 , to introduce the general structure of the non-circular gear speed change tran...

Abstract

A variable-speed transmission mechanism based on non-circular gears, comprising: a driving wheel and a plurality of driven wheels with the same modulus of all gear teeth, which are respectively fixed on a driving shaft and a driven shaft at a set angle, and The transition gear teeth and the speed change gear teeth on the non-circular pitch curve between the adjacent driven wheels; wherein, the transition gear teeth and the speed change gear teeth on the non-circular pitch curve are used to complete the driving wheel between the adjacent two-stage driven wheels Shifting between gears, that is, on the premise of keeping the speed of the driving wheel unchanged, and then applying an axial feed motion to the driving wheel, the driving wheel can sequentially follow the non-circular pitch curve between the driven wheels at all levels The meshing of the transition gear teeth, the shifting gear teeth and the transition gear teeth on the upper part completes the shifting and shifting, and no longer needs to go through the process of stopping and clutching. The device abandons the clutch and uses the non-circular gear on the non-circular pitch curve to realize the variable speed transmission between the two shafts.

Description

technical field [0001] The invention relates to a speed change transmission mechanism with an innovative structure, to be precise, relates to a speed change transmission mechanism based on non-circular gears, and belongs to the technical field of mechanical transmissions. Background technique [0002] The transmission is a mechanical transmission device that can change the transmission speed between the output shaft and the input shaft, and it is also a mechanical device that changes the operating speed or traction of machines such as machine tools, automobiles, and tractors. The transmission is usually installed between the driving shaft and the driven shaft of the engine, and can change the transmission ratio of the output shaft and the input shaft in a fixed or stepped manner. As a key component in many mechanical structures, the performance and efficiency of the transmission directly affect the operation of the entire machine. [0003] The gear transmission is a mechani...
