[detailed description of the invention]
First embodiment:
Conventional helical axle, as depicted in figs. 1 and 2, including central shaft 1 and be sheathed on the helical blade on central shaft 1；Described helical blade is that to be surrounded on central shaft 1 peripheral and formed for pinniform by the stacking of staggering successively of some axle laminations 2.
As it is shown on figure 3, the outer surface of central shaft 1 arranges the keyway 3 of two symmetries along the bearing of trend of this central shaft 1.
As shown in Figure 4, axle lamination 2 includes the set axle collar 21, spoke 22；The set axle collar 21 has centre bore, is provided with the locator protrusions 23 matched with the keyway 3 on central shaft 1, is used for being set in corresponding keyway 3 in this centre bore.The spoke 22 of axle lamination 2 starts staggered layers stack arrangement successively from first, often has certain angle [alpha] between the spoke 22 of adjacent two bobbin laminations 2；Along with the stacking of axle lamination 2, the arrangement in pinniform of the spoke 22 of axle lamination 2, thus forming helical blade in central shaft 1 periphery.As it is shown in figure 5, angulation α between the second bobbin lamination spoke 22 and the first bobbin lamination spoke 22.
Its manufacture method is as follows:
