The common conjugatesurface includes tooth surface of gear, working surface of solid CAM, helicoidal surfaces existing in spiral burr, worm, chip flute of cutters, and so on.
Because a pair of conjugatesurface can be ground precisely, the transmission accuracy of the worm drive is improved, the load-carrying capacity is increased and service life is prolonged.
其一对共轭齿面均可精确磨削。因此，该传动不仅可以提高传动精度，而且又能提高承载能力和延长使用寿命。

Takes the screw type compressor rotor as an example, a calculating method of unknown section profile of spiral surface and its conjugate shape is introduced and practical formulas are given.
