Ball bearing common way of ball screw according to the situation by force at work, where the sale of ball screw, screw support bearings and stop often to push the ball bearing assembly, which is supported in the following ways: 1) Push a freestyle double thrust bearings mounted at one end and the other end dangling. Because one end is the free state, so the carrying capacity of small, low axial stiffness. 2) Double Push one end of a simply-supported thrust bearing mounted, and the other end loaded radial ball bearings, axial stiffness is not too high; should pay attention to reduce the thermal deformation of the screw, ball manufacturers, should be installed pay attention to the heat source and the common screw segment when working away from the loading end of the thrust bearing, thrust bearing to prevent elongation due to heat generated screw gap. A. Ball working principle and characteristics of the ball screw nut ball screw and nut due between placed the ball, so that between the ball screw and nut into rolling friction, ball sales, thus greatly reduced the friction, Pu'er Ball, improve the transmission efficiency. Ball screw and nut formed with a spiral groove arc surface, will they fit together they form a spiral raceway, during which both the rotation and the ball rolling cycle.
