通常情况下,正面式杠杆百分表(以下称杠杆百分表)的示值超差,主要是由于齿轮传动部分误差以及杠杆臂长误差(杠杆比失准)两大原因造成的;当然还有其他原因造成示值超差,例如测力和各部分相互作用的影响,配合精度、装配质量等等方面的影响。我们假设杠杆百分表的测力在规定范围内,各部分相互作用不存在问题,各齿轮轴与轴孔配合情况符合间隙配合精度,装配质量良好。在这里,我 Normally, positive indication of lever type dial indicator (hereinafter referred to as the lever dial indicator) value tolerance, mainly due to the transmission part of the error and the lever arm length error (leverage ratio misalignment) two major causes; of course There are other reasons for the indication of over-tolerance, such as the impact of the force and the interaction of the various parts, with the accuracy, assembly quality and so on. We assume that the leverage of the dial indicator is within the specified range and there is no problem with the interaction between the various parts. The fit of each gear shaft with the shaft hole fits the clearance fit precision and the assembly quality is good. Here, me
