如图所示,是我们设计的电机轴伸键槽对称度通用测量工具,适用于糟宽10mm以上,φ55～85的轴伸键槽对称度的检验。其中调节角铁1与测量横臂2、表架固定杆5的接触面成凸起120°,使其能在测量横臂和表架固定杆120°槽内滑动。在测量横臂和表架固定杆的一侧面,刻有适用于各种规格键槽的刻线,由螺钉通过拉板6固定在纵向或横向的任意位置。0点支承3可调,以便适用于不同宽度的键槽。辅助支点4
As shown in the figure, it is a universal measuring tool for the symmetry of the motor shaft keyway designed by us. It is suitable for the inspection of the symmetry degree of the shaft extension keyway of 10mm or more and φ55 ~ 85. The adjustment angle iron 1 and the measurement cross arm 2 and the contact surface of the fixing rod 5 of the measuring frame protrude by 120 ° so as to be able to slide within the measuring groove of 120 ° of the measuring arm and the fixing rod of the measuring frame. In the measuring arm and table fixing rod on one side, engraved with a variety of key groove engraved line by the screws through the pull plate 6 fixed in any position of the vertical or horizontal. Adjustable 0 point support 3, so that for different width of the keyway. Auxiliary fulcrum 4
