齿轮大都以圆孔作为加工与运转基准,因此齿轮孔的加工精度将直接影响齿形的加工精度与齿轮的工作质量。对于齿部需要热处理的带中心孔齿轮、在热处理后一般都要进行磨孔。本文介绍一种高精度弹性齿轮磨孔夹具,这种夹具可以使用液压、气动或电动进行操作。图1是利用改装后的DK 2 Most of the gear to the hole as a processing and running benchmark, so the gear hole machining accuracy will directly affect the tooth profile machining accuracy and gear quality. For the teeth need heat treatment with the center hole gear, after the heat treatment generally have to grind the hole. This article describes a high-precision resilient gear grinding fixture that can be operated hydraulically, pneumatically or electrically. Figure 1 is the use of modified DK 2
