渐开线斜齿轮除了用于平行轴传动外,还可以用于相错轴传动,即螺旋传动。由于在螺旋传动时,斜齿轮齿面之间理论上成点接触状态,一般认为它仅只能用以实现运动的传递而并不宜于传递动力。汽车拖拉机凸轮轴与分配轴之间传动用的正时齿轮是这种传动最常见的例子。采用螺旋传动在某些场合下具有结构简单、制造方便的优点,所以近年来在较小功率传动中获得了一定程度的发展。例如丹麦的蛋粉生产线中,离心分离机就是以螺旋传动作为
In addition to involute helical gear for parallel axis drive, but also can be used for the wrong axis drive, that is, screw drive. As the helical gear transmission, the helical gear tooth surface in theory into a point of contact between the state, generally considered only to achieve the transfer of movement and not suitable for the transmission of power. The most common example of this kind of transmission is the timing gear for driving between the tractor camshaft and the distribution shaft. The use of helical transmission in some cases has the advantages of simple structure, easy manufacture, so in recent years the smaller power transmission has been a certain degree of development. For example, Danish egg powder production line, the centrifuge is a screw drive as
