Problems solved by technology

[0002] The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover and the working machine. Mechanisms play the role of matching speed and transmitting torque. They are widely used in modern machinery. With the development of mechanical technology, the technology of reducers is also improving. There are various reducers on the market, but the existing The high-speed ratio reducers of today have defects such as large size, heavy weight, unfavorable installation, short life, and high cost. At present, the market is in urgent need of a large speed ratio with small size, light weight, low cost, long life, stability and reliability. reducer

Abstract

The invention belongs to the technical field of speed reducers, and provides a large-transmission-ratio speed reducing method and device. The large-transmission-ratio speed reducing method achieves speed reduction by constructing a driving gear which revolves around a fixed shaft only but not rotates on own axis, and the method achieves the effect of revolution only but no rotation on the basis ofa parallelogram principle. The device comprises a box body, an input shaft, an output shaft, a first rotating frame and a first transmission set; the input shaft, the output shaft and the first rotating frame are all rotationally arranged on the box body; and the first transmission set is arranged on the first rotating frame, and is used for linkage of the first rotating frame and the output shaft. According to the technical scheme, the problems of simplex transmission ratio and poor structure compactness of a speed reducer in the prior art are solved.
