The standard is only a selective range, and the entity manufacturer with many years of experience-the machine factory, pushes it under high powerGear couplingThe more common inner hole of the involute spline is added and the second is convenient for installation. The calculation formula and key points of the shaft hole size!CouplingThe manufacturer makes a brief introduction!There are many styles of splines, and the standard is for all tolerance levels.In this way, it is allowed to match the inner and outer splines of different tolerance levels. The advantage of this is that the manufacturing difficulty of one mating part will be significantly less than that of the other counterpart. The average tolerance of the two parts is the small effect of the tolerance inner spline required by the design. The tooth space thickness is the same as the large-action tooth thickness of the external spline.There are two forms of cooperation in this standard.For tooth flank fit, the small-acting tooth slot size and the large-acting tooth thickness are the same.The fundamental reason for the interchangeability of splines during assembly is that they do not consider the tolerance level of individual splines during manufacturing. Practice is the key. I believeCouplingCustomers pay more attention to machinery!Product·As shown in the picture——
