图1是履带式推土机上的支重轮轴,其定位槽长度L尺寸直接影响浮动油封的压紧力。该尺寸原采用样板测量,质量难以保证,为此我们制造了图2所示检具,配上图3所示环规,环规直径D等于支重轮轴上定位沟槽长度基本尺寸L,公差等级要求达1T5,并开缺口和配等高块。 检测前,将图2检具千分表一头搁在图3环规内的等高块上,定位螺杆一头嵌在环规上的缺口内,并将定位螺杆紧密贴在环规内壁,同时将千分表调到零位。测量时,将检具上的
Figure 1 is a track-type bulldozers on the axle, the length of the positioning groove L size directly affect the floating seal pressure. The size of the original template measurement, quality is difficult to guarantee, for which we have fabricated the fixture shown in Figure 2, coupled with ring ring shown in Figure 3, ring diameter D is equal to the length of the positioning groove on the axle Shaft basic size L, tolerance Level requirements up to 1T5, and open the gap and distribution contour block. Before the test, place the gauge in Figure 2 and rest it on the contour block in the ring gauge in Figure 3. One end of the positioning screw is embedded in the notch on the ring gauge, and the positioning screw is closely attached to the inner wall of the ring gauge, Dial indicator transferred to zero. When measuring, the gage will be checked
