Abstract

The planetary speed reducer specially for continuous casting includes one cabinet assembled with one front body, one back body, one first middle body, one second middle body and one third middle body; four ring gears connected through pins and screws; one input shaft, planet carriers, sun gears and one output shaft coaxial mutually. The input shaft on the front body is float connected to the first sun gear through a ring gear, the first planet carrier is connected to the second sun gear through one spline, the second planet carrier is connected to the thir sun gear through one spline, the third planet carrier is connected to the fourth sun gear through one spline and mounted through bearing on the second middle body and the third middle body, the four planet carrier is mounted through bearing on the third middle body and the back body and has one end extending beyond the back body to constitute the hollow output shaft. The present invention has compact structure, high reliability and other advantages.

Description

technical field [0001] The invention relates to a reducer, in particular to a special planetary reducer for continuous casting. Background technique [0002] Continuous casting and rolling energy-saving and consumption-reducing technology is generally adopted in the steelmaking process for energy-saving transformation of steel plants. The continuous casting planetary reducer, the key equipment of the production line, urgently needs to be localized to replace imports. The technology 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. It is not only possible to design high-performance reducers, but also to manufacture high-performance and high-reliability reducers. 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] Aiming at the...
