Abstract

A special decelerator for a spiral drag for dregs utilities a double-class driving case combining a K-H-V a different gear planet type transmission with a NGW model planet type transmission. The structure of the difference gear planet type transmission consists of an input shaft and a deviating axel bearing into an input part. The swing wheel is combined with the needle wheel into the internal meshing planet type transmission of the swing with the needle gear. The decelerating part consists of a needle gear housing and a needle wheel made of a group of needle gear pins evenly distributed on the needle gear housing, and the output part consists of a gear wheel made of a group of pin shafts and the pin sleeves evenly distributed at the end of the gear shaft round disc, achieving the transmission activity to obtain the lower output running speed; The structure of the NHG-model planet type transmission is made of a inner gear ring, a gear shaft, public planet gear and an output shaft. The input shaft is the output shaft from the structure of K-H-V a different gear planet type transmission, i.e. the gear shaft; the gear shaft drives the planet gear to rotate, the planet gear is meshed with the inner gear ring which is not moved. The planet gear automatically and commonly rotates to drive the output shaft to run. The insurance device on the input shaft utilities the cutting-pin type structure. Therefore it is simple structure and convenient replace.
