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
