Large torque reduction box for withdrawal and straightening machine

Abstract

The invention relates to a large torque reduction box for a withdrawal and straightening machine. One or more stages of cylinder gear transmission sets, a tail stage taper gear, a tail stage gear shaft, an output large gear and an output hollow shaft are arranged in a box, a motor flange is arranged on one side of the box, an input gear shaft extends into the box from the motor flange, the part, outside the box, of the input gear shaft is connected with a coupler, a tooth part of the part, inside the box, of the input gear shaft is in transmission connection with the one or more stages of cylinder gear transmission sets, a cylinder gear shaft of the last stage of cylinder gear transmission set in the one or more stages of cylinder gear transmission sets is provided with a small taper gear,the small taper gear is meshed with a tail stage large taper gear connected to the tail stage gear shaft in a sleeving manner, and the tooth part of the tail stage taper gear is meshed with an outputlarge gear connected to the output hollow shaft in a sleeving manner. The large torque reduction box is simple in structure and capable of effectively giving consideration to the high speed ratio andthe large torque.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a high-torque speed reducer for a tension straightening machine. Background technique [0002] The reducer used on the metallurgical continuous casting tension leveling machine is generally composed of a box body, a box cover, a flange, an input shaft, a hollow shaft and a gear transmission mechanism. The traditional cylindrical gear transmission mechanism cannot take into account the high speed ratio and high torque requirements of its use. However, the existing bevel gear set input can meet the speed ratio requirements, but the final torque is relatively small, and cannot meet the increasingly high continuous casting requirements. Contents of the invention [0003] The invention provides a high-torque speed reducer for a tension leveling machine with a simple structure and can effectively meet the requirements of a large speed ratio and a large torque. [0004] The technical solution adopt...
