Ball bearing common way of ball screw according to the situation by force at work, Wuhu ball screw, screw support often thrust bearings and radial ball bearing assembly, ball much money, which supports the way are the following Species: 1) Push a freestyle double at the end of the thrust bearing mounted, and the other end dangling. Because one end is the free state, so the carrying capacity of small, ball use, 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, the installation should pay attention to the heat source and the screw Common operation section end remote from the thrust bearing means to prevent the thrust bearing due to thermal elongation of the screw gap. A. Outer circulation ball screw pretension a way to increase the ball diameter: screw carrying capacity. Since the ball contacts 4:00, thus, frictional resistance is large, easy to heat, when a small preload preload torque smoothly suitable for small preload, transmit motion two occasions, the displacement lead: Ball points contacts. Since only one nut, washer or nut eliminate manufacturing errors arising from the inclination and affect preload nut torque. Thus, tightening torque smooth, ball manufacturers, but carrying small. Suitable for pre-load, positioning accuracy is required. Third, the gaskets: two-point contact ball. Screw carrying capacity, may exert greater preload preload preload when small torque smoothly. Suitable for high load, positioning accuracy is required. Ball, Shandong Fu Jun (certified), Wuhu ball screw is provided by Mechanical Technology Co., Ltd. Shandong Fu Jun. Machinery Co., Ltd.
