Introduction to Production Process of Inner Spline of Motorcycle Sprocket
Introduction to the production process of motorcycle sprocket inner spline:
1) When the distortion and contraction of the internal spline are small, the mandrel diameter can be 3-4 mm smaller than the minor diameter of the internal spline of the gear.
2) If the distortion and shrinkage of the internal spline are small, the mandrel can be appropriately thickened, with a diameter of 1-2 mm smaller than the minor diameter of the gear internal spline.
3) When the distortion and contraction of the internal spline are large, a mandrel with an external spline can be used. The outer diameter and tooth side of the spline mandrel are 0.15 to 0.20 mm smaller than the major diameter and tooth side of the internal spline of the gear.
4) For gears with tapered spline holes after quenching, corresponding countermeasures should be taken when designing their mandrels. For gears with large and small ends in the spline hole after quenching, the spindle should be inserted from the easily inserted end during quenching, and only about half the height can be inserted.
5) For gears with spline hole shrinkage at both ends and drum shape in the middle after quenching, the middle part of the spindle can be reduced in size, and only the major diameter of the spline hole at both ends of the gear can be controlled during quenching.
6) When the inner spline is (now) in a reverse waist drum shape, the mandrel can be made into different diameters in the form of a string of sugar balls. The parts with large shrinkage are thickened, and their diameter is 0.5~1.0mm smaller than the minor diameter of the spline in the gear; The mandrel at the position with small shrinkage is thinner, and its diameter is 3-4 mm smaller than the minor diameter of the spline in the gear.
