Abstract

The invention discloses an easily adjustable speed change device. The easily adjustable speed change device comprises a baseplate, an input shaft and an output shaft, wherein a speed change adjustingcomponent is arranged between the input shaft and the output shaft; articulated sliding blocks are slidably arranged on a limiting rotating shaft and are matched with limiting grooves in a sliding manner; the two groups of articulated sliding blocks are symmetrically laid on the limiting rotating shaft; hanging loops are fixedly connected to the articulated sliding blocks; connecting rods are articulated on the hanging loops; the other ends of the connecting rods are articulated on articulated blocks; the connecting rods on the same side are articulated on the same articulated block; rotatingwheels are articulated on the tops of the articulated blocks; a driving belt is arranged on the rotating wheels in a tensioning manner; the other end of the driving belt is connected to the output shaft; and a driving device is arranged on the baseplate and is connected to the articulated sliding blocks. The easily adjustable speed change device has a simple structure and strong practicability; the articulated sliding blocks are driven to move, and the rotating radius of the rotating wheels changes, so that the transmission ratio between the output shaft and the input shaft changes, and the speed adjustment is further realized. The easily adjustable speed change device has high speed regulation accuracy and good application prospect.

Description

technical field [0001] The invention relates to the field of transmissions, in particular to an easily adjustable transmission. Background technique [0002] The transmission is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in fixed or stepwise steps, also known as the gearbox. Speed ​​changer is made up of speed change transmission mechanism and operating mechanism. There are two types of transmissions: stepped transmission and continuously variable transmission. The stepped transmission is the most widely used one. It adopts gear transmission and has several fixed-value transmission ratios; stepless transmission refers to a transmission system that can continuously obtain any transmission ratio within the transmission range. The best match between the drive train and the engine operating conditions can be obtained through continuously variable transmission. [0003] As far as...
