随着精密端齿分度台在精密机械加工领域中的应用,对其提出了需具备更大承载能力的要求。在分析精密端齿分度台结构的基础上,针对影响齿盘分度精度的齿形参数、锁紧力以及齿部啮合状态等因素进行了有限元分析及设计,并进行了试验验证,最后提出了一种全新的齿形研磨工艺,从而提高了齿形研磨精度和效率,保证了大承载精密端齿分度台的精度。

With the application of precision hirth couplings indexing table in precison mechanical machining field, the needs for large load capacity is proposed. Based on the analysis of the structure of the hirth-coupling indexing table, the FEA and design and experiments are carried out on the parameters of hirth sharp, locking force and meshing state of the hirth. A new kind of gear lapping process is proposed, which improves the precision and efficiency of the hirth lapping, and finally guarantees the precision of the high load hirth couplings indexing table.
