Ball is a kind of rolling the ball as an intermediary for the ball screw drive system. Based transmission can be divided into two types: 1, the rotary motion into linear motion. 2, the linear motion into rotary motion. Its advantages: greatly reduces the work of friction, high sensitivity, no wobbling when starting machinery, no noise, can be very precise control of micro feed. Ball bearing common mode according to the situation by force working supply of ball screw ball screw, screw support often thrust bearings and radial ball bearing assembly, which is supported in the following ways: 1, a single push Single Push thrust bearing were installed at both ends of the ball screw and preloaded. It can improve the axial stiffness of the ball screw; when pre-stretched install preload larger ball screws, therefore bear only pulling work when the screw. 2, a pair of push-push-push attached to both ends of the thrust bearing and the combination of purchasing ball screw ball bearings, in order to have the maximum rigidity Ball screw production, it can be used at both ends of double bearing, thrust bearing lasts and radial ball bearings, and clamping force is applied to the top. This method is suitable for high rigidity, high-speed high-precision precision lead screw drive system. However, this structure allows the thermal deformation mode conversion screw preload the thrust bearing, thus requiring stents increase the carrying capacity and stiffness of the thrust bearing design.
