求翻译：轴承在工作状态时的游隙，工作时内圈温升最大，热膨胀最大，使轴承游隙减小；同时由于负荷的作用，滚动体与滚道接触处产生弹性变形，使轴承游隙增大。轴承工作游隙比安装游隙大还是小，取决于这两种因素的综合作用。有些滚动轴承不能调整游隙，更不能拆卸，这些轴承有六种型号，即0000型至5000型；有些滚动轴承可以调整游隙，但不能拆卸，有6000型（角接触轴承）及内圈锥孔的1000型、2000型和3000型滚动轴承，这些类型滚动轴承的安装游隙，经调整后将比原始游隙更小；另外，有些轴承可以拆卸，更可以调整游隙，有7000型（圆锥滚子轴承）、8000型（推力球轴承）和9000型（推力滚子轴承）三种，这三种轴承不存在原始游隙；6000型和7000型滚动轴承，径向游隙被调小，轴向游隙也随之变小，反之亦然，而8000型和9000型滚动轴承，只有轴向游隙有实际意义。合适的安装游隙有助于滚动轴承的正常工作。游隙过小，滚动轴承温度升高，无法正常工作，以至滚动体卡死；游隙过大，设备振动大，滚动轴承噪声大。是什么意思？

Clearance of the bearing when the work, inner temperature rise when maximum, maximum heat expansion, the bearing clearance reduction; at the same time as the load function, contact rolling elements and raceways produces elastic deformation, the bearing clearance increases. Bearing clearance than the installation clearance is large or small, depends on the combination of these two factors. Some rolling bearing cannot adjustment tour gap, more cannot demolition, these bearing has six species model, is 0000 type to 5,000 type; some rolling bearing can adjustment tour gap, but cannot demolition, has 6,000 type (angle contact bearing) and the within ring cone hole of 1000 type, and 2000 type and 3,000 type rolling bearing, these type rolling bearing of installation tour gap, by adjustment Hou will than original tour gap more small; also, some bearing can demolition, more can adjustment tour gap, has 7,000 type (Cone roll child bearing), and 8,000 type (thrust ball bearing) and 9,000 type (thrust roll child bearing) three species, this three species bearing not exists original tour gap; 6,000 type and 7,000 type rolling bearing, radial tour gap was adjustable small, axis to tour gap also with of variable small, and vice versa, and 8,000 type and 9,000 type rolling bearing, only axis to tour gap has actual significance. Appropriate installation clearance contribute to the work of rolling bearings. Clearance is too small, rolling bearing temperature, does not work, as well as the rolling stuck; clearance is too large, vibration and noise of rolling bearings.
