四球摩擦磨损试验机中磨斑的测量
Four-ball friction and wear testing machine of the grinding spot measurement
磨斑的测量是做四球摩擦磨损试验中zui重要的一环，今天恒旭小编就给大家介绍一下磨斑测量的相关知识。
The measurement of ground spotis the most important part of the four-ball friction wear test. Today, we will give you some knowledge about the measurement of the ground.
钢球磨斑的测量是利用我司专门研制的磨斑测量系统来完成的，测量精度为0.01mm，通过底部安装台的特殊设计，能在不取出钢球的情况下，对油盒中三个钢球的磨斑进行测量、测量时先将油盒放置在显微镜座上，使钢球对准显微镜的物镜，再转动调焦手轮，求得清晰的磨斑。旋转油盒，用同样的方案依次测量出另外两钢球的平均磨斑直径。三钢球平均磨斑直径的算术平均值即为本次实验的平均磨斑直径。
Of ball mill is developed by using our special grinding spot measurement system to complete, the measuring accuracy is 0.01 mm, through special design at the bottom of the mounting plate, can not take out the steel ball, under the condition of three steel ball mill in the oil box of spot measurement, measurement when oil box first placed on a microscope, the steel ball on the microscope objective lens, then turn the focusing handwheel, get clear spots. The rotary oil box is used to measure the average grinding diameter of the other two steel balls in the same scheme. The arithmetic mean of the average diameter of the three steel balls is the average grinding diameter of the experiment
一般情况下，对于同一磨斑，在PB点之前，磨斑读测数据，横向大于或等于纵向，在PB点之后，磨斑读测数据，纵向大于或等于横向，均属正常。
In general, for the same spot, before the point of PB, grinding spot to read the test data, and the horizontal is greater than or equal to the longitudinal direction, after the PB point, grinding spot to read the test data, and vertical is greater than or equal to the horizontal, as normal.
