Ball working principle and characteristics of the ball screw nut ball screw and nut due between supply Ball into the ball, so that between the ball screw and nut into rolling friction, therefore considerably reduced frictional resistance, 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. Stiffness of the ball screw nut, in most cases, far less than the RZ rigidity ball screw nut ball screw stiffness Rmu, Rmu generally 3-5 times of RZ. In the design of the ball screw factory, general accounting Ball End stiffness, you will not need to be accounted for separately stiffness of the ball screw nut. Ball bearing are the following four, due to the different way the support, so as to permit axial load and allowable rotation speed are different, the customer should be selected according to their own circumstances. 1. Fixed - fixed for high-speed, high-precision, high requirements for installation 2. Fixed - support for medium-speed, high-precision ball screws price, the most common support structure 3. The support - support for medium-speed, in accuracy. 4. Fixed - free for low speed, the precision, short axial screw buy Ball, Ball Shangqiu, Shandong Fu Jun is provided by Mechanical Technology Co., Ltd. Shandong Fu Jun. Machinery Co., Ltd.
