查询词典 power transmission

Its function is:①Changing gear ratio,expanding the torque of the driving wheel and the range of the rotational speed,to adapt the travel condition which frequently changes, like start, acceleration, climbing and so on, simultaneously causes the engine to work under the advantageous operating mode;②Under the premise of the invariable rotation, enables the automobile to travel back;③Using neutral, severances the power transmission, to make the engine start, idle, and is advantageous for the engine to shift gears or to carry on the dynamic output.

它功用是：①改变传动比，扩大驱动轮转矩和转速的变化范围，以适应经常变化的行驶条件，如起步、加速、上坡等，同时使发动机在有利的工况下工作；②在发动机旋转方向不变的前提下，使汽车能倒退行驶；③利用空档，中断动力传递，以使发动机能够起动、怠速，并便于发动机换档或进行动力输出。

Whenever possible, the power-transmission elements, such as gears or pullets, should be located close to the supporting bearings, This reduces the bending moment, and hence the deflection and bending stress.

只要有可能，电力传输内容，如齿轮或pullets ，应靠近配套轴承，这可减少弯矩，因此，挠度和弯曲应力。

Whenever possible, the power-transmission elements, such as gears or pullets, should be located close to the supporting bearings, This reduces the bending moment, and hence the deflection and bending stress.

若情况许可，应该设置力量传输元素，例如齿轮或小母鸡，接近支持的轴承，这减少弯曲力矩、并且偏折和弯曲应力。
