External spline rolling cold rolling precision forming the contact area calculation and simulation
Minimal. (3) and r, △ s is approximately linear proportional relationship, r its impact is negligible. On the function, the previous paragraph is a parabolic function, mutations near the midline, which is a mathematical model of the boundary points on the cause. (4) unit area of contact with the workpiece modulus m, increases linearly increased. But the module to determine the workpiece,[link widoczny dla zalogowanych], the workpiece diameter on the unit have little effect on contact area, in the Z> 40 one after the contact area tends to extremes. (5) = 37.5 units in the contact area. Near the sharp decline. References: [1] Zheng Quangang. Straight cylindrical small modulus involute spline cold rolling molding technology [J].
