深沟球轴承套圈的保持架是使钢球之间保持均匀间隔,在轴承转动过程中,随钢球而旋转,同时钢球在保持架的兜孔内自转。保持架与钢球表面之间有复杂的运动,产生摩擦力,又有离心力、圆周切向力等其他方向的作用力,所以保持架在轴承中是重要的零件,同时受到各种作用力。 Deep groove ball bearing ferrule cage is to maintain uniform spacing between the steel ball in the process of rotation, with the steel ball rotation, while the ball in the cage pocket rotation. Cages and the ball surface between the complex movement, resulting in friction, but also centrifugal force, circumferential tangential force and other directions of the force, so the cage is an important part of the bearing, at the same time by a variety of forces.
