The tooth root transition curve is not a simple connecting area but a critical structure that balances stress concentration, ensures manufacturing feasibility, and optimizes lubrication. It refers to the transition curve connecting the working part of the tooth profile to the root circle, and its de

Hobbing is a machining method that uses a gear hob (equivalent to a helical gear with very few teeth) on a hobbing machine. Through the forced meshing motion between the hob and the gear blank, the gear blank is continuously cut into the predetermined tooth profile. Essentially, it simulates the mes

In the fields of modern rail transit, aviation, and high-end mechanical equipment, gear transmission not only requires high efficiency and reliability but also excellent NVH performance (Noise, Vibration, Harshness). The level of NVH directly affects the user experience and service life, and also ha

Gear transmission is a fundamental mechanical power transmission method widely used in various machinery, renowned for its compact structure, high efficiency, and ability to transmit large torques. This article explores its classification, key parameters, lubrication methods, and practical applicati
