The tilting machine is specifically designed based on the structural features of the 250t converter tilting system, offering several key advantages. One of its main characteristics is the synchronization of operation. This is achieved through four drive motors and four primary gear reducers. The input shafts of the two sets at the same height are connected via steel couplings, ensuring consistent movement. An electric control system further enhances synchronization, allowing the two pairs of motors to operate in unison, which guarantees uniform performance across all four power input units.
Another important feature is load equalization. Each speed reducer is equipped with a planetary gear system, where the sun gear extends axially outward. This allows the two connecting shaft crank systems to work together, forming a load-sharing compensation mechanism. As a result, the load from the secondary reducer’s drive gears is evenly distributed among the four units. Even if one motor fails or operates at a different level, the load can still be balanced between the output gears of the two primary reducers, improving reliability and performance.
This design is more efficient than traditional fixed connections between gearbox flanges. It improves the stress distribution on the gear shafts, simplifies manufacturing, and makes installation easier. Additionally, the horizontal force generated by the tilting torque is transferred through the lower push rod of the secondary reducer gearbox to the support systems on both sides. From there, it is transmitted horizontally to the foundation via butterfly springs, enhancing stability and reducing mechanical stress.
The system primarily includes a central wheel, a sun gear, three planetary gears with their supporting arms, bearings, and connecting rod mechanisms. These components are arranged within the passive large bevel gear of the second stage of the primary reducer. The central wheel and the large bevel gear rotate in the same direction. The third stage of the reducer is mounted on the support arm shaft of the planetary gear. The driving pinion is connected to the sun gear shaft, which extends out of the speed reducer and is fitted with a crank at the end. This crank is symmetrically positioned relative to the crank of the primary speed reducer used for elevation, and the two are linked via connecting rods. The four primary speed reducers are interconnected in two layers, contributing to a compact and efficient design.
