Description

Worm gear and worm gear speed reducer for walking of steel mill

Technical Field

The utility model relates to a speed reducer, a worm gear speed reducer for steel mill walking specifically says so.

Background

With the rapid development of industrial technologies in China, the requirements on speed reducers in mechanical equipment widely applied to industries such as metallurgy, mines, chemical engineering, construction, agriculture, transportation, power generation and the like are higher and higher. In the operation process of the existing steel mill, a speed reducer matched with an automatic production line is required to give consideration to directional power input and output, and simultaneously ensure larger torque and load capacity, and if the speed reducer with a traditional standard structure transmission structure is adopted, the required power transmission cannot be given consideration to.

Disclosure of Invention

The utility model provides a simple structure has directional power input and output, has simultaneously big moment of torsion and high load capacity simultaneously concurrently and is used for steel mill walking worm gear reducer.

The utility model adopts the technical proposal that: the utility model provides a be used for steel mill walking to use worm gear reducer, includes box and case lid down, and the box is constituteed to the case lid encapsulation lower box, its characterized in that: the box body is reduced by inclining from left to right, the end part of the right end of the lower box body is connected with an input worm in a penetrating mode, a first-stage intermediate shaft, a second-stage intermediate shaft and an output shaft are sequentially supported on the lower box body from right to left, the input worm is meshed with a worm wheel on the first-stage intermediate shaft, the first-stage intermediate shaft is meshed with and drives the second-stage intermediate shaft through two first-stage gear sets respectively at two symmetrical ends of the worm wheel, the second-stage intermediate shaft is meshed with and drives the third-stage intermediate shaft through a second-stage gear set at the central position of the two first-stage gear sets, the third-stage intermediate shaft is meshed with.

Furthermore, a sight glass hole is formed in the box cover, wherein the box body is inclined and reduced.

Further, the inner end of the input worm is supported on a supporting seat in the lower box body.

Furthermore, the input worm is supported on the right side of the lower box body through a bearing seat, the inner side of the bearing is limited and tightly abutted to an inner step on the input worm, the outer side of the input worm is screwed and locked and pressed on the outer side of the bearing through a stop washer and a round nut, the outer side of the bearing is pressed and connected through a through cover penetrating on the input worm, and an oil seal is arranged between the through cover and the input worm.

The utility model discloses a worm is by box right side horizontal input, through worm meshing worm gear transmission one-level jackshaft, and the gear drive between one-level jackshaft to second grade jackshaft, tertiary jackshaft to output shaft is the balanced transmission of double gear symmetry, is favorable to improving transmission stability, combines unification, two, tertiary gear train gradual change increase, is favorable to improving the moment of torsion and the load capacity of speed reducer, produces the orientation of supporting walking practicality, moment of torsion and the load capacity requirement on the line in being fit for the steel mill.
