Worm and gear gear reducer for travelling in steel mill

Abstract

The invention relates to a worm and gear gear reducer for travelling in a steel mill. A box body is obliquely shrunk from left to right, the right end part of a lower box body is connected with an input worm in a penetrating mode, a first-stage intermediate shaft, a second-stage intermediate shaft, a third-stage intermediate shaft and an output shaft are sequentially supported on the lower box body from right to left, the input worm meshes with a worm wheel on the first-stage intermediate shaft, the two ends, symmetrical about the worm wheel, of the first-stage intermediate shaft are in engaged transmission with the second-stage intermediate shaft through two first-stage gear sets, the second-stage intermediate shaft is in engaged transmission with the third-stage intermediate shaft through second-stage gear sets in the center positions of the two first-stage gear sets, and the two ends, symmetrical about the second-stage gear sets, of the third-stage intermediate shaft are in engagedtransmission with the output shaft through two third-stage gear sets, the output shaft extends out to be externally connected for output, and the first-stage gear sets, the second-stage gear sets andthe third-stage gear sets are gradually enlarged. The structure of the worm and gear gear reducer for the travelling in the steel mill is simple, directional power input and output are achieved, and meanwhile large torque and high load capacity are achieved.

Description

technical field [0001] The invention relates to a reducer, in particular to a worm gear reducer used for walking in steel mills. Background technique [0002] With the rapid development of my country's industrial technology, the requirements for reducers widely used in mechanical equipment in metallurgy, mining, chemical industry, construction, agriculture, transportation, power generation and other industries are getting higher and higher. In the operation process of existing steel mills, the reducer used in the automatic production line requires both directional power input and output, while ensuring a large torque and load capacity. If the reducer with the traditional standard structure transmission structure is used, it cannot Take into account the required power transmission. Contents of the invention [0003] The invention provides a worm and worm gear speed reducer for steel mills with simple structure, directional power input and output, high torque and high load ...
