螺旋齿花键和直齿花键相比,加工和检测都要困难得多,螺旋齿花键的使用也因此而受到一定的限制。螺旋齿花键由于键齿是螺旋形的,当花键轴的轴向位置固定时,与其相配合的加工有花键孔的零件,依靠键齿的螺旋形状,可以在转动时自动产生轴向位移,使花键传动联接自动脱开。螺旋齿花键传动联接主要用在一些起动机构上,例如在大型汽车或拖拉机上,起动时用小功率的起动电机或小功率发动机带动大功率的主发动机,当主发动机经过起动投入工作之后,即可利用螺旋齿花键传动联接的特点,使起动装
Spiral toothed splines and straight splines compared to the processing and testing are much more difficult, the use of helical splines are therefore subject to certain restrictions. Spiral tooth spline Because the spline is helical, when the spline shaft axial position is fixed, its matching spline hole machining parts, relying on the helical shape of the key teeth, can be automatically generated when rotating axial Displacement, the spline transmission automatically disconnect. Spiral gear transmission coupling is mainly used in some start-up mechanism, such as in a large car or tractor, starting with a small power starter motor or a low-power engine to drive a high-power main engine, when the main engine after starting into work, namely Spiral gear can be used to connect the characteristics of the spline to start the installation
