Not only determines the relative position relationship between the upper wheel sheet 1 and the lower wheel sheet 2, but also prevents the upper wheel sheet 1 and the lower wheel sheet 2 from rotating relatively. The centre bore of wheel piece and the centre bore of lower wheel piece 2 are transition fit with shaft 4, and the contact fit that adopts the dysmorphism hole can disperse the strength for the location, reduces the torsion that the center pin received, prevents that the strength from concentrating to make the center pin twist-off, and in addition, non-circular center pin and wheel piece dysmorphism centre bore are transition fit, and this structure makes things convenient for dismouting and maintenance, effective reduce cost. The distance between two straight edges in the wheel piece position nail long hole in the wheel piece is equal, the two side edges are circular arcs, the tolerance required by the long hole is relatively looser than that required by the circular hole, only the distance between the two straight edges is required to be accurate, and the circular arc part is required to be reduced in precision, so that the processing difficulty is reduced. The wheel sheet is a gear sheet, a wafer or a shifting head.
Example 1: the description will be made by taking a double-layer wheel sheet as an example
As shown in fig. 1 to 4, when the wheel sheet refers to the upper wheel sheet 1, the centers of the upper wheel sheet 1 and the lower wheel sheet 2 are provided with center special-shaped holes 1b and 2b (the special-shaped holes involved in the mechanism are holes which are not standard circles), and the upper wheel sheet 1 is provided with an upper wheel sheet position nail long hole 1a which is matched with the limit nail 3 and is in clearance fit; the upper wheel sheet 1 and the lower wheel sheet part are arranged on the wheel shaft 4, and the upper wheel sheet 1 and the lower wheel sheet 2 are matched with wheel shaft positioning surfaces 4a on the wheel shaft 4 through center special-shaped holes 1b and 2 b.
