Sliding infinitely variable-speed mechanism for non-collinear driving

Abstract

The invention belongs to the technical field of variable-speed mechanisms, and particularly relates to a sliding infinitely variable-speed mechanism for non-collinear driving. The sliding infinitely variable-speed mechanism for non-collinear driving comprises a gearbox body, a spherical cavity wall, a universal shaft sleeve, a hydraulic cylinder, variable-speed execution shafts, a transmission shaft, a variable-speed plate, a universal joint, a transitional shaft, a variable-speed cone, a guide rail, a guide rail sliding block and the like, wherein the universal shaft sleeve is installed in the spherical cavity and can make an input shaft and an output shaft to rotate in a universal mode, the variable-speed mechanism is made to adapt to the non-collinear driving and speed varying conditions of the input shaft and the output shaft, and the two execution shafts achieve non-collinear driving through the universal joint and the transitional shaft. During speed varying, the variable-speed cone and the variable-speed plate are the same in linear speed at the contact point, and as the respective contact points are different from the axes in radial length, the rotation speed of the input shaft is different from that of the output shaft, and thus, speed variation is achieved; and the mechanism is complex in design, but the non-collinear variable speed function achieved by the mechanism has certain practical value, and the mechanism has great market prospects.

Description

[0001] This application is a divisional application of an invention patent application titled: A sliding continuously variable transmission mechanism suitable for non-collinear transmission, with the application date: July 10, 2015, and the application number: 201510401048.8. technical field [0002] The invention belongs to the technical field of speed change mechanisms, and discloses a sliding stepless speed change mechanism for non-collinear transmission. Background technique [0003] The speed change mechanism is divided into gear shift and stepless speed change. The stepless speed change has gradually replaced the gear shift due to the advantage that the transmission ratio can be continuously changed. For the current speed change mechanism, the input shaft and the output shaft have a fixed angle requirement. If the shaft output shaft is unstable and there is a certain angle change, if the traditional speed change mechanism is used directly, it will have a greater impact ...

Problems solved by technology

[0003] The speed change mechanism is divided into gear shifting and continuously variable speed. The continuously variable speed gradually replaces the gear shifting because of the advantage that the transmission ratio can be continuously changed. For the current speed changing mechanism, the input shaft and the output shaft have a fixed angle requirement. For the input If the shaft output shaft is unstable and there is a certain angle change, if the traditional speed change mechanism is directly used, it will have a greater impact on the speed change mechanism, and even damage the transmission parts of the speed change mechanism

The current solution is that additional universal joints need to be added to match the position and angle of the input shaft and output shaft, which is somewhat complicated to implement
