When none of the sliding gears is in mesh with its countershaft gear, the gears are said to be in neutral.

如果没有变速齿轮组与副传动轴上的齿轮啮合，这时，就叫做空挡。

When designing a gearset one cannot consider torque alone.

设计齿轮组时至考虑扭矩是不够的。

The new style rolling mill has no need of replacement gear wheel group then , physical design cuts down , consumptive material is the machinery that such has improved greatly to controllable nature (3) rolling mill rolling copper coin accuracy short, on old-fashioned rolling mill basis slightly easy to change , to handle conveniently, be that laboratory scientific research has lightened burden , has economized cost under the control of.

新式轧机则不需更换齿轮组，这样大大提高了对轧制铜板精度的可控性（3）本轧机的机械结构设计精简，耗材少，在老式轧机基础上略作改动，方便操作，便于控制，为实验室科研工作减轻了负担，节省了成本。

FA304 and FA318 series and advanced design of the machine, send a reasonable, high precision, low energy consumption, the use of rapid change in the exchange of draft gear group and three on three-under-Ji Chen care under pressure rods hyperbolic new technologies such as drawing, Significantly improve the quality of the cooked.

FA304和FA318系列并条机设计先进，传送合理，精度高，能耗低，采用快速交换变位牵伸齿轮组和三上三下下托式防积尘压力棒双曲线牵伸等新技术，显著提高熟条质量。

When has the vehicles after the caterpillar band, vehicles' kinetic energy transmits through the friction gives the caterpillar band, then drives the gear cluster, finally causes the generator electricity generation.

当有车辆经过履带时，车辆的动能通过摩擦传递给履带，然后带动齿轮组，最后使得发电机发电。

The point contact condition can not only avoid the tooth edge contact, decreases the kinematical errors and vibro-acoustic due to axial misalignments, but also increases the bearing strength of the contact gears.

点接触的接触型态不仅能使齿轮组避免齿缘的接触及降低由轴向组装误差所引起的运动误差和振动噪音，更可增强齿轮的接触强度。

Based on the software Pro/Engineer,the solid model of the increasing speed gear system for wind-power generation is built.
