Abstract

The invention discloses a stepless speed change device to solve the problem that gear transmission of the prior art cannot achieve stepless speed change. The stepless speed change device includes a rack, a driving shaft, a driven shaft perpendicular to the driving shaft, a drive block which is installed between the drive shaft and the driven shaft, a worm gear which is rotationally connected to the drive shaft and a worm which meshes with the worm gear. The drive block includes a first bevel gear and a hemisphere block which are fixed together, the drive shaft is provided with a second bevel gear which engages with the first bevel gear, and the driven shaft is provided with a disk which is matched with the hemisphere block. Half of the worm gear is smooth, another half of the worm gear is provided with a worm teeth part with worm tooth. The smooth part is provided with a fixed rod, the drive block and the fixed rod are rotatably connected with each other, and the smooth part and end face of the worm teeth part are both provided with a bumping and a slot both in the shape of an inverted cone. The stepless speed change device is simple in structure and capable of achieving stepless speed change.

Description

technical field [0001] The invention relates to the technical field of transmission, in particular to a continuously variable transmission device. Background technique [0002] The transmission mechanism is commonly used in machine tools. The transmission mechanism is more commonly used for gear transmission. However, due to the fixed number of gear teeth and the fixed transmission ratio of the gear transmission, multiple speed changes or even infinitely variable speeds cannot be realized. Contents of the invention [0003] The present invention intends to provide a continuously variable transmission device to solve the problem that the gear transmission cannot be continuously variable in the prior art. [0004] The continuously variable transmission device in this program includes a frame, a driving shaft, a driven shaft perpendicular to the driving shaft, a transmission block arranged between the driving shaft and the driven shaft, a worm gear connected in rotation with ...
