Abstract

The planetary speed reducer specially for roller way includes flange, cabinet, the first and the second sun gears, the first and the second planet carriers, planet gears and hollow output shaft. The first and the second sun gears, the planet carrier and the hollow output shaft are coaxial; the first sun gear is connected to the output shaft of the speed reducer; the first planet carrier is connected to the second sun gear, and the second planet carrier is connected to the output shaft of the speed reducer; there are at least two planet gears around each of the first and the second planet carriers; and the first planet gears and the second planet gears are meshed to corresponding ring gear and sun gear.

Description

technical field [0001] The invention relates to a reducer, in particular to a special planetary reducer for roller tables. Background technique [0002] Aiming at the urgent need for localization of roller table planetary reducers in steel mills to replace imports, especially now that the reducer manufacturing industry in my country is developing unprecedentedly, the manufacturing technology of reducers is becoming more and more mature, the performance of raw materials is improving day by day, and the design level is improving day by day. Not only can we design high-performance The reducer can also produce a high-performance and high-reliability reducer. The current planetary reducer: the transmission ratio composed of input and output components cannot be properly matched, which limits its maximum bearing capacity of the reducer. Contents of the invention [0003] The present invention aims at the above disadvantages, and provides a special planetary reducer for roller ta...
