磨头轴承的调整好坏,直接影响到磨头的精度。调整轴承的本质,在于滚球与滚道之间以适宜的间隙。间隙过小,运转时轴承易发热,不但影响轴承寿命,而且因为轴承是薄壳型结构,过热会使轴承变形而影响精度;间隙过大,保证不了磨头的精度。要获得合理的间隙,关键在于调整轴承内、外垫圈的厚度差。 Adjusting the grinding head bearing, directly affects the accuracy of the grinding head. Adjust the essence of the bearing, lies in the ball and the raceway to the appropriate gap. The gap is too small, easy to run bearing heat, not only affect the bearing life, and because the bearing is a thin shell structure, overheating will affect the bearing deformation deformation; gap is too large to guarantee the accuracy of grinding head. To get a reasonable gap, the key is to adjust the bearing, the thickness difference between the outer gasket.
