Abstract

The invention relates to a manual and motorized dual-input speed reducer comprising a shell. An output shaft and a worm and gear mechanism are arranged in the shell, a worm gear is fixedly and serially connected to the output shaft, a worm is meshed with the worm gear, the extension end of the worm is connected with a handwheel, a small worm gear, a small warm and a switching device are further arranged in the shell, the switching device is arranged between the handwheel and the small worm gear, the small warm gear is fixedly connected on the worm in a sleeving manner, and the small worm is penetratingly connected to the shell and connected with an input motor. The small worm drives the large worm through the small worm gear, the large worm drives the output shaft to perform output through the large worm gear, a flange is connected with a connecting disc under the manual input condition, the large worm is driven manually through connection of the flange and the connecting disc, the large worm is meshed with the large worm gear to drive the output shaft to perform output, and accordingly manual and automatic duel input is realized. By matching of a spring screw and a ball with a ball hole on the shaft, the flange is positioned under the condition that the spring is disconnected or connected with the connecting disc, and connection is prevented from being affected by sliding of the flange.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a manual motorized double-input speed reducer used for adjusting the position of a ram on an intermediate frequency furnace. Background technique [0002] Intermediate frequency furnaces are generally used for melting metals. In the prior art, intermediate frequency furnaces generally rely on the motor to drive the reducer to realize the dumping of molten metal. In the case of a power failure, the motor cannot be driven, and the molten metal can only be cooled in the road; when fine-tuning is required , the motor drive is difficult to implement. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the object of the present invention is to provide a speed reducer with manual, motorized and dual-input functions. [0004] For achieving above object, the technical scheme that the present invention takes is: [0005] A manual ...
