Abstract

The invention relates to a chain transmission speed changing box mechanism comprising a speed changing box shell and a power input shaft, wherein a power input shaft chain wheel, a lower drive shaft chain wheel, an upper drive shaft chain wheel and a chain are arranged in the speed changing box shell, the power input shaft chain wheel, the lower drive shaft chain wheel and the upper drive shaft chain wheel are distributed in a triangular shape and arranged in a plane, the chain sequentially bypasses the power input shaft chain wheel, the lower drive shaft chain wheel and the upper drive shaft chain wheel to form a closed loop, the power input shaft chain wheel is arranged on the power input shaft, and the lower drive shaft chain wheel and the upper drive shaft chain wheel are respectively and correspondingly arranged on a lower drive shaft and an upper drive shaft. The speed changing box mechanism reduces processing difficulty and production cost by using the chain wheels for replacing gears, increases transmission distance and saves transmission stages by using chain transmission for replacing gear transmission.

Description

technical field [0001] The invention relates to a speed change mechanism with single power input and double power output, in particular to a chain transmission gearbox mechanism. Background technique [0002] Machines are an important tool in the development of modern society. The gearbox is one of the important parts in a machine, that is to say, when a machine is invented and created, there is a gearbox to determine its certain working process. [0003] Now with the gradual development of the machine, the types of gearboxes have also become diverse. However, the structure of the gearbox of most machines is mostly a combination of a shell, a gear set and a gear shaft according to certain rules. The technology of this kind of gearbox is relatively mature. Although the appearance is various, the internal structure is basically the same Yes, people are familiar with the production and manufacture of this kind of gearbox, so this kind of gearbox is mostly used in machines. U...
