特大型球轴承沟道直径的测量

特大型深沟球轴承内圈沟径、外圈沟径和某些角接触球轴承中圈沟径的测量,因受仪器测量范围的限制,无法采用现有专用仪器进行测量。采用一些特殊测量方法,可以直接或间接地测量或控制沟道直径。附图7幅。

Because of the limitation of instrument's measuring range, the diameters of outer ring raceways and inner ring raceways in extra large deep groove ball bearings as well as the diameters of medium ring raceways in some angular contact ball bearings are unable to be measured using existing special instruments. Some particular methods can be used to measure or control the diameters of raceways directly or indirectly.
