The processing steps for drum gear couplings web：https://www.timothyholding.com/The-processing-steps-for-drum-gear-couplings.html What are the processing steps for drum gear couplings ? Drum gear couplings are generally processed through turning and milling operations (CNC milling ensures higher precision). Keyways can be machined via wire cutting or broaching. Processing Methods: Typical manufacturing steps include turning, milling, gear hobbing, and gear shaping. The tooth surfaces undergo high-frequency quenching. For higher performance requirements, die forging is used to shape the coupling before machining. Some couplings are formed using cast steel or cast iron, followed by machining. Technical Overview: Drum gear couplings fall under the category of flexible-rigid couplings. They consist of internal gear rings and flanged half-couplings with external teeth. The external teeth are either straight or drum-shaped. Compared to straight-tooth couplings, drum-shaped teeth allow for greater angular displacement, improve tooth contact conditions, enhance torque transmission capacity, and extend service life. Key Advantages: 1. High Load Capacity: The carburizing and quenching treatment of the drum-shaped tooth surfaces significantly increases load-bearing capacity. 2. Reduced Wear: When forced oil lubrication is applied, tooth surface wear decreases dramatically (to approximately 10% of that with grease lubrication). Circulating oil also dissipates heat generated by rolling mills and gear friction, preventing degradation of the material’s allowable contact stress. 3. Durability: Under normal conditions, tooth breakage is avoided, meeting the demands of continuous rolling mill operations. 4. Axial Flexibility: The design accommodates axial displacement during rolling mill operation, enabling easy expansion and contraction. 5. Operational Benefits: Safe, clean, and efficient performance. https://www.timothyholding.com/The-processing-steps-for-drum-gear-couplings.html
