Description

Single-piece independent transmission type cone pulley

Technical Field

The utility model relates to the technical field of cone pulleys, in particular to a single-piece independent transmission cone pulley.

Background

The cone pulley is a pulley with various diameters and is a transmission member for changing the rotating speed. Usually two cone pulleys are used together. The power and the motion are input by the driving shaft, and are output by the driven shaft through the belt and cone pulley device. When the diameters of the driving wheel and the driven wheel where the belt is positioned are equal, constant-speed transmission is realized. The position of the belt is changed, and when the belt is positioned at the position that the diameter of the driving wheel is smaller than that of the driven wheel, the speed reduction transmission is realized.

When the prior cone pulley assembly is used, most of cone pulley shafts are connected with external power equipment, and because cone pulley pieces on the cone pulley assembly are connected with each other, the cone pulley pieces at the end part can drive the rest multi-stage cone pulley pieces to synchronously realize transmission while rotating. When the multi-stage cone pulley piece is used, independent transmission of the cone pulley piece of one stage is difficult to realize, so that the cone pulley piece is difficult to meet various use requirements, and the cone pulley piece needs to be improved.
