SASL200×300无心磨床(德意志民主共和国产品)的导轮轴前轴承,原来是采用球面调心轴承(见图1),并通过并帽调整球面轴承的配合间隙,其作用是使导轮在旋转时可自动调心。一、存在问题导轮旋转是无级变速的。在连续磨削工件时,导轮必须有倾斜角,使工件前进,大部分倾斜角为1°至3°。该设备经多年使用,导轮轴承球面磨损,划出多道沟痕。虽经几次修理,但球面磨损太多,已失去了原来的配合精度,无法继续再用,自制又有一定的困难,致使导轮失去自动调心作用。
SASL200 × 300 centerless grinder (German Democratic Republic of the product) of the guide wheel shaft bearings, the original is the use of spherical self-aligning bearings (see Figure 1), and through the cap and adjust the spherical bearing with the gap, its role is to make the guide wheel in rotation Self-aligning. First, there are problems guide wheel rotation is continuously variable speed. During continuous grinding of the workpiece, the guide pulley must have a bevel angle to allow the workpiece to advance with most of the bevel angle between 1 ° and 3 °. After years of use of the device, the spherical roller bearing wear, scratched multi-channel mark. Despite several repairs, but the spherical wear too much, has lost the original with the precision, can not continue to reuse, self-made and have some difficulties, resulting in the guide wheel loses the role of self-aligning.
