材料试验机齿杆端部形状的分析试验机的测力部分,绝大多数是齿杆端部,它与摆锤推板相接触的部分,都安装着可调螺丝,可调螺丝的作用,是借以使指针调整零位。指针对刻度盘的零位位置,一般是不会变动的,当使用不同度盘时,由于缓冲器的影响及试验机安装不水平度的影响,很有可能使指针对准零位发生改变,这是在检定过程中经常发生的问题。在这种情况,可以用齿杆端部的可调螺 Material testing machine rack end of the shape analysis of the testing machine force measuring part, the vast majority of the end of the rack bar, which is in contact with the pendulum hammer plate parts are installed with adjustable screw, adjustable screw role, Is to make the pointer to adjust zero. Pointed to the dial zero position, generally does not change, when using different degrees of disk, due to the impact of the buffer and the impact of the test machine is not installed level, it is possible to make the pointer aligned zero change, This is a problem that often occurs during the verification process. In this case, you can use the end of the rack bar adjustable screw
