Embodiment Construction

[0015] Now in conjunction with accompanying drawing 1~9 will illustrate working process:

[0016] (1) Working process of power transmission mechanism:

[0017] Taking Fig. 4 as an example, the power input shaft 1 drives the conical disks 2a-2b to rotate, and the conical disks 2a-2b, through the transmission chains 7a, 7b, drive the sprockets 5a, 5b to rotate, and the sprocket 5b is coaxially integrated with it. The sprocket 5b0 drives the sprocket 5a0 to rotate through the chain 70, and the coaxial sprocket 5a, 5a 1 、5a 2 by sprocket 5a 1 The chain 7c drives the sprocket 5c to rotate, and the sprocket 5 drives the power output shaft 6c to rotate to complete the power transmission process.

[0018] (2) Working process of variable speed control mechanism:

[0019] Turn the speed regulating handle 11 to axially move the end face bearing 8a for speed change, and make the shafts 6a, 6b in the chute 10a through the push-pull action of the speed change connecting rod 12a, 12b. 1...

Abstract

Cone disc chain wheel tumbler and engagement drive stepless gear with variable driving radius characterized by that, the speed transmission is realized by changing the contacting radius of the chain on the chain wheel with variable driving radius, and using their combined action to realize the stepless speed change together with the fixed chain wheel. The invention also discloses a variable intermeshing stepless speed change gear using the parallel axes central distance, and also an engagement drive stepless gear of the planet-sprocket structure.

Description

technical field [0001] A conical disc-sprocket transmission part with variable transmission radius and a meshing transmission continuously variable transmission belong to the technical field of meshing transmission stepless transmission. Background technique [0002] Commonly used mechanical continuously variable transmissions transmit power through the frictional force between transmission components, and they all have disadvantages such as poor reliability, low transmission efficiency, and limited transmission power. Contents of the invention [0003] The object of the present invention is to provide a conical disk-sprocket transmission member with variable transmission radius and a meshing transmission continuously variable transmission made of it. The invention realizes the speed change by changing the contact radius of the chain on the conical disk with variable transmission radius, and then realizes the torque transmission through the meshing transmission of the mesh...
