Second gear spline pad 90A-1701132 For FAST
1, Material selection
The current mainstream uses 42CrMo steel instead of traditional 40Cr or 35CrMo steel, and achieves a hardness of 220-250HBW through quenching and tempering treatment, balancing strength and processing performance.
Plastic forming adaptability: The high plasticity characteristics of 42CrMo are more suitable for cold/hot extrusion or rolling processes, which is beneficial for improving the density of product structure.
2, Forming process
Rolling forming: Using a symmetrical rack and pinion mold, the surface metal of the workpiece is pressed in through synchronous staggered motion to achieve integrated plastic forming of the spline tooth shape, with high efficiency and stable accuracy.
Thread synchronous forming: Combined with roller extrusion method, the collaborative processing of splines and threads is completed in the same process, reducing the cost of process switching.
3, Precision machining and assembly adaptation
Grinding treatment: Reserve grinding allowance for key mating surfaces, and use an outer circle grinder for precision repair to meet the high tolerance requirements of transmission assembly.
