四球摩擦磨損試驗(yàn)機(jī)中磨斑的測(cè)量
Four-ball friction and wear testing machine of the grinding spot measurement
磨斑的測(cè)量是做四球摩擦磨損試驗(yàn)中zui重要的一環(huán)，今天恒旭小編就給大家介紹一下磨斑測(cè)量的相關(guān)知識(shí)。
The measurement of ground spot is the most important part of the four-ball friction wear test. Today, we will give you some knowledge about the measurement of the ground.
鋼球磨斑的測(cè)量是利用我司專門研制的磨斑測(cè)量系統(tǒng)來(lái)完成的，測(cè)量精度為0.01mm，通過(guò)底部安裝臺(tái)的特殊設(shè)計(jì)，能在不取出鋼球的情況下，對(duì)油盒中三個(gè)鋼球的磨斑進(jìn)行測(cè)量、測(cè)量時(shí)先將油盒放置在顯微鏡座上，使鋼球?qū)?zhǔn)顯微鏡的物鏡，再轉(zhuǎn)動(dòng)調(diào)焦手輪，求得清晰的磨斑。旋轉(zhuǎn)油盒，用同樣的方案依次測(cè)量出另外兩鋼球的平均磨斑直徑。三鋼球平均磨斑直徑的算術(shù)平均值即為本次實(shí)驗(yàn)的平均磨斑直徑。
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
一般情況下，對(duì)于同一磨斑，在PB點(diǎn)之前，磨斑讀測(cè)數(shù)據(jù)，橫向大于或等于縱向，在PB點(diǎn)之后，磨斑讀測(cè)數(shù)據(jù)，縱向大于或等于橫向，均屬正常。
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.
