Problems solved by technology

Because the friction parts are easy to slip, the transmission torque is small. Taking the automobile CVT transmission as an example, the maximum torque that can be achieved at present is 300N.m; in addition, due to the need to provide pressure on the friction parts, the deformation factor of the friction parts causes a large transmission loss

Embodiment Construction

[0011] Referring to Fig. 1 and Fig. 2, in the screw adjustable continuously variable transmission device of the embodiment, the crank 2 is sleeved on the power input shaft 1, and the output shaft 16 is provided with the driving gear 6, and the driving gear 6 is sleeved by a one-way bearing. On the output shaft 16, a carriage is fixed on the driving gear 6, and the base 7 of the carriage is fixed on the driving gear 6 along the radial direction of the driving gear 6. The slider of the carriage is provided with a fulcrum 5, the fulcrum 5 It is connected with the crank 2 through the transmission of the connecting rod 3, and when the crank rotates, the carriage swings back and forth from side to side.

[0012] One side of the driving gear 6 is also provided with a driven gear 9 meshing with it, and the driven gear 9 is sleeved on the auxiliary shaft 11 through another one-way bearing 10 of the same rotation direction.

[0013] On the back of the driving gear 6 and the driven gear ...

Abstract

The invention discloses a screw rod regulation-typed stepless speed change device which is sleeved with a crank on a power input shaft; a driving gear is arranged on an output shaft and sleeved on the output shaft by a one-way bearing; a planker is fixed on the driving gear; a sliding block of the planker is connected with the crank in a transmission way by a connecting rod; one side of the driving gear is also provided with a driven gear which meshes with the driving gear; the driven gear is sleeved on an auxiliary shaft by the other one-way bearing with the same steering direction; on the back surfaces of the driving gear and the driven gear, the output shaft and the auxiliary shaft are fixed with two small gears respectively which transmit by the meshing of a middle gear. When in work, the crank drives the planker to cause the driving gear to make corresponding reciprocating rotation, and the output shaft is driven by the gear mechanism to rotate continuously. By regulating the swinging working radius of the planker, the transmission ratio between the input shaft and the output shaft is changed. The device transmits by the connecting rod and a swing arm, and has large transmission torque and small loss in the transmission process.

Description

technical field [0001] The invention relates to a transmission, especially a continuously variable transmission. Background technique [0002] The current continuously variable transmission has the forms of belt or steel belt continuously variable transmission, cone-disc planetary continuously variable transmission, etc., all of which are driven by friction. Because the friction parts are easy to slip, the transmission torque is small. Taking the CVT transmission of an automobile as an example, the maximum torque that can be achieved at present is 300N.m; in addition, due to the need to provide pressure on the friction parts, the deformation factor of the friction parts causes a large transmission loss . Contents of the invention [0003] The purpose of the present invention is to provide a non-friction transmission continuously variable transmission with high torque. [0004] The solution of the present invention is: a screw adjustable continuously variable transmission...
