齿轮

These approaches are suitable for noncircular gear not only with discontinuous pitch curve but also with continuous pitch curve.

这一方法不仅适用于节曲线不连续的非圆齿轮设计，对节曲线连续的非圆齿轮设计也同样适用。

Thus, it is of great theoretic and realistic significance to research on correlative technology of gears.

因此，研究齿轮及齿轮加工的相关技术具有很大的理论和现实意义。

Later, with the application of gears, two cotton gin with a pair of roller blades to replace the original gear ...

后来，随着齿轮的应用，轧棉机的两个压辊采用一对齿轮。。。

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。

Reverse speed is obtained by the use of a small/pinion R between the countershaft gear I and the sliding gear K, which causes the transmission drive shaft to be driven in the opposite direction.

相反速度被在对桥之间的小/鸟翼 R 的使用获得以齿轮连起我和滑齿轮 K，引起传输驱动轴在相反的方向中被驱使。
