Conical variable diameter pulley continuously variable transmission

Abstract

The utility model relates to a conical variable-diameter pulley continuously variable transmission, which relates to a transmission device. It includes rotating and adjusting the worm shaft, through which the worm on the worm shaft is driven and connected to the drive screw of the two conical discs. The output conical disc pushes the radius of the segmented push rod pulley to change evenly with the change of the section radius of the input conical disc and the output conical disc at the transmission ring, realizing stepless speed change. When the invention works, the position of the pulley reducing mechanism remains unchanged, and the stepless speed change is realized by changing the positions of the input conical disc and the output conical disc. It has the advantages of simple structure, manual speed adjustment, simple and convenient operation, small size, few parts, light weight, high work efficiency, large transmission torque and long service life.

Description

technical field [0001] The invention relates to a speed change device, in particular to a conical variable diameter pulley continuously variable speed changer. Background technique [0002] In the existing cone ring type continuously variable transmission, the gear teeth are directly processed on the cone body, which is difficult to process and has low strength, and the impact is large when the gear teeth mesh. At present, most of the existing cone-type continuously variable transmissions achieve stepless speed change by changing the transmission parts (such as belts or rings) between the two cones. Since the change of the transmission parts requires a large driving force, and the fluctuation is large, it is impossible to use manpower. Adjustment limits the scope of application of this type of continuously variable transmission. Other types of transmissions, such as multi-disc friction type, steel ball outer cone wheel type, hydraulic motor and other continuously variable t...

Problems solved by technology

[0002] In the existing cone-ring continuously variable transmission, the gear teeth are directly processed on the cone body, which is difficult to process and not high in strength, and the impact is large when the gear teeth mesh

At present, most of the existing cone-type continuously variable transmissions achieve stepless speed change by changing the transmission parts (such as belts or rings) between the two cones. Since the change of the transmission parts requires a large driving force, and the fluctuation is large, it is impossible to use manpower. adjustment, which limits the scope of application of this type of continuously variable transmission

Other types of transmissions, such as multi-disc friction type, steel ball outer cone wheel type, hydraulic motor and other continuously variable transmissions, have low transmission efficiency and poor stability; dual-clutch transmissions have disadvantages such as high manufacturing precision, complicated processing technology, high cost, and difficult maintenance.
