Gear type slip continuously variable transmission

Abstract

The invention discloses a gear type slip continuously variable transmission. The continuously variable transmission comprises an inner gear, a first transmission shaft and an input shaft, wherein an outer ring of the inner gear is rotationally supported through a bearing, the inner gear comprises arc teeth arranged on an inner ring, outer ring teeth meshing with the arc teeth are arranged on eachof shaft bodies of the first transmission shaft and the input shaft, an axis of at least one of the first transmission shaft and the input shaft can create a staggered angle with an axis of the innergear, the continuously variable transmission further comprises a second transmission shaft, a third transmission shaft, a universal coupling and an output shaft, the output shaft is rotationally supported through a bearing, the second transmission shaft and the third transmission shaft are connected through the universal coupling, the other end of the second transmission shaft is in transmission connection with a sliding sleeve at one end of the first transmission shaft, and the other end of the third transmission shaft is in transmission connection with a sliding sleeve at one end of the output shaft.

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
