Trapezoidal gear base

F1-F7 Trapezoidal gear base

The base of the human-shaped gear is supported by a sliding bearing. For a long time, the temperature of the bearing bush of the human-shaped gear base has been a bottleneck restricting the production of the rolling mill. And the scraping and grinding of the bearing bush of the human-shaped gear base has become a key technical problem in the repair of the rolling mill over the years. Based on the numerous problems that occurred during the actual maintenance process over the years, the technical key points of bearing bush scraping and grinding, the operation key points during the scraping and grinding process, and the assembly and inspection key points after scraping and grinding are analyzed. Based on the current on-site situation and theoretical data, the operation process steps are deeply refined to ensure that after the scraping and repairing of the bearing bush of the rolling mill, the temperature of the bearing bush of the human-shaped gear base is controlled within the production requirements, providing equipment support for stable production.
