main gear transmission

The paper also sets up the general dynamic model for gear transmission, analyses the vibration and noise principle of the main parts in the gear transmission system like gear and bearing.

论文同时建立了齿轮传动通用动力学模型，分析了齿轮传动系统中齿轮和轴承等主要零部件的振动和噪声机理。

This text introduces the type, operating principle, structure, main function, key technique of the power multiple-branching transmission of the gear box and solving measures.

重点介绍了齿轮箱功率多分支传动型式、工作原理、结构和主要性能，以及关键技术和解决的措施。

But as the main vehicle powertrain component, the transmission needs the help of shift Actuator to complete the gear shift.

变速器作为车辆传动系的主要部件，需要借助于换档执行机构来完成换档。
