A gear type slip continuously variable transmission

Abstract

The invention discloses a gear type slip continuously variable transmission, which comprises an internal gear, a first transmission shaft and an input shaft, the outer ring of the inner gear is rotatably supported by bearings, the inner gear includes arc teeth arranged on the inner ring, the first Both the transmission shaft and the input shaft have outer ring teeth meshing with the arc teeth on the shaft body, and the axis of at least one of the first transmission shaft and the input shaft and the axis of the inner gear can form an interlaced angle. The continuously variable transmission also includes a second transmission shaft, a third transmission shaft, a universal coupling and an output shaft, the output shaft is rotatably supported by bearings, and the second transmission shaft and the third transmission shaft are connected together by a universal coupling , the other end of the second transmission shaft is in transmission connection with one end of the first transmission shaft through a sliding sleeve, and the other end of the third transmission shaft is in transmission connection with one end of the output shaft through a sliding sleeve.

Description

technical field [0001] The invention relates to the field of transmissions, in particular to a gear type slip continuously variable transmission. Background technique [0002] A transmission is a commonly used mechanical device that is used to increase or decrease the speed by a certain percentage while transmitting power. [0003] In the prior art, the transmission is generally only adjusted in a fixed ratio. Under the structure of multiple pairs of gear sets, the step-by-step speed regulation is realized. The car with the transmission (CVT) has continuously variable speed transmission through the metal belt and the friction of the inclined plane. Although the function of the continuously variable speed is realized in the structure, there are several problems: the ability to transmit torque needs to be improved; The process is noisy, and if the precision of the parts is not enough, the noise will be very loud. Moreover, the maintenance period of the transmission is much sh...

[0003] In the prior art, the transmission is generally only adjusted in a fixed ratio. Under the structure of multiple pairs of gear sets, the step-by-step speed regulation is realized. The car with the transmission (CVT) has continuously variable speed transmission through the metal belt and the friction of the inclined plane. Although the function of the continuously variable speed is realized in the structure, there are several problems: the ability to transmit torque needs to be improved; The process is noisy, if the precision of the parts is not enough, the noise will be very loud, and the maintenance cycle of the transmission is much shorter than that of the transmission gear box; when starting at an ultra-low speed, it may fail to start
