被测静压轴瓦(图1),由于孔内有四个等分油槽、四个空刀、八条筋和两端圆周筋,精度要求较高(图1),用一般内径千分表很难检查。为解决静压轴瓦孔的检测问题,我们采用了一种自制检具(图2)。检具的结构:三等分的检具体镶有三个导轨,一个导轨紧固在检技术要求;φ85D孔锥度0.01,椭圆度0.005具体上,两个导轨可用四个弹簧和 Static pressure bearing was measured (Figure 1), due to the hole has four equalizer tank, four empty knife, eight ribs and the two ends of the circumferential ribs, high accuracy (Figure 1), with the internal diameter gauge is very difficult an examination. In order to solve the problem of static pressure bearing hole detection, we use a self-made test fixture (Figure 2). Check the structure of the fixture: trisection of the inspection body set with three rails, a guide rail fastening inspection requirements; φ85D hole taper 0.01, ellipticity 0.005 Specifically, the two rails can be four springs and
