Winding drum with speed reducer

Abstract

The invention discloses a winding drum with a speed reducer and aims to provide a winding drum with a speed reducer, having the advantages of small space occupation and few power transmission links. The invention adopts the technical scheme that the winding drum with the speed reducer comprises the winding drum, an electric motor, the speed reducer, a shaft coupler and a left end cover, wherein the speed reducer fixed on the left side of a flange is arranged in the winding drum, an output shaft of the electric motor fixed on the right side of the flange is fixedly connected with a power input shaft of the speed reducer through the shaft coupler, the left end of an output shaft of the speed reducer is rotationally connected with the left end cover, a left baffle plate of the winding drum is fixedly connected with output shaft of the speed reducer, and the inner side of the drum wall on the right end of the winding drum is rotationally connected with the flange through bearings. The winding drum with the speed reducer has the technical effects that because the speed reducer is arranged in the winding drum, and the output shaft of the speed reducer directly transmits power to the winding drum, the winding drum has small space occupation and few power transmission links and saves part of steel.

Description

technical field [0001] The invention relates to a drum on a crane, especially a drum with a reducer. Background technique [0002] At present, the rotating power of the drum of the crane is transmitted to the drum transmission shaft by the reducer located outside the drum through the transmission parts such as the output shaft of the reducer, the coupling, and the transmission shaft, and the drum transmission shaft carries the drum together Rotation, the reducer is set outside the reel to take up a certain space, and there are too many intermediate links in power transmission. Contents of the invention [0003] The purpose of the present invention is to provide a reel with a reducer that occupies less space and has fewer power transmission links. The technical solution of the present invention is completed in this way. The reel with the reducer includes a reel, a motor, a reducer, a coupling, and a left end cover. It is characterized in that the reducer fixed on the left ...
