The axial fixed position preload is applied to middle ring of the shaft, the axial rigidity of the angular contact ball bearing is obtained by the impulse excitation tests.
Through analyzing example, the relation between axial rigidity and pulling force of the cable and the affection to axial rigidity about gravitation rigidity and elastic stiffness have been discussed.
通过算例分析,讨论了索的轴向刚度与拉力变化的关系,分析了重力刚度和弹性刚度对轴向刚度的影响;
Cylindrical roller adopt convexity process, so the presses of roller and race surface are proportional spacing, they can bear a large axial load, furthermore axial rigidity is strong.
