In light of the operation requirements of finishing mill unit, and learning from foreign products, the company has organized a technical challenge tacking project and developed a hard tooth-surface curved-tooth coupling with forced dilute oil cycling lubrication for which it has full proprietary intellectual property right.

Product characteristics:
1. The tooth-curved adopt a dual trace tooth shape to meet the requirement for high precision rotating heavy-load working condition;
2. The tooth-curved surface is treated by carburizing, quenching and grinding, ensuring a high meshing accuracy and bearing capacity;
3. Forced dilute oil lubrication is adopted for the tooth surface meshing part, reducing the tooth surface wear by 80% compared with that of conventional grease lubrication. The cycling dilute oil can effectively prevent the decrease of the permissible contact stress of the gear tooth surface, satisfying the requirement for continuous rolling mills;
4. The tooth-curved connecting shaft can satisfy the requirement for the roller shifting and is conveniently retractable;
5. It operates in a safe and clean manner.
