Problems solved by technology

There are many kinds of transmissions with existing mechanical structures, some of which are complex in structure and high in manufacturing cost, and some structures cannot be applied to mining machinery and equipment. Therefore, it is difficult for existing transmissions to be used in transportation equipment and medium and small winches in mining areas.

Abstract

The invention provides a speed changer, comparing a casing whose one end is equipped with sun gear, first stage teeth of the sun gear engage with those of first stage planetary gear, the first stage planetary gear engages with first stage inner gear ring, first controller is equipped outside the first stage inner gear ring, the other end of the casing is equipped with spoke which engages with second stage and third stage inner gear rings, third stage teeth of the sun gear engage with those of second stage planetary gear, the second stage planetary gear engages with the second stage inner gear ring, third stage teeth of the sun gear engage with those of third stage planetary gear, the third stage planetary gear engages with the third stage inner gear ring, second controller is equipped outside the second stage inner gear ring, and third controller is equipped outside the third stage inner gear ring. And it mainly applies to conveyances and in small-sized and middle-sized lift winches in mining areas, able to implement accurate speed change in adverse circumstances and having long service life.

Description

technical field [0001] The invention relates to a transmission, which is a mechanical transmission transmission. Background technique [0002] Transmissions include mechanical transmissions and electrical variable frequency transmissions, etc. Due to the wide range of applications of mechanical transmissions, especially the ability to use them in harsh environmental conditions such as flammable and explosive, they are very popular among enterprises. There are many kinds of transmissions with existing mechanical structures, some of which are complex in structure and high in manufacturing cost, and some structures cannot be applied to mining machinery and equipment. Therefore, it is difficult for existing transmissions to be used in transportation equipment and medium and small winches in mining areas. . Contents of the invention [0003] The object of the present invention is to provide a speed changer, which is mainly used in transportation equipment in mining areas and s...
