Jiaxing bearing | about basic knowledge of ball screw nut pair

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Ball screw nut pair in nc machine tool is rotary motion into linear motion transmission device in common use. It with ball rolling instead of lead screw nut pair of sliding, the friction force is small, has a good performance. 1, the composition of the ball screw nut pair: screw, nut, ball and raceway ( Back to the bead) And nut. 2, the working principle of ball screw nut pair on the screw and nut has a circular spiral groove, will they involution form the spiral groove. In a ball in the race, when the relative movement between the screw and nut, along the spiral groove ball rolling, rolling on the screw by return after several laps boot device and one roll back to the screw and nut, form a closed loop. 3, ball screw pair of advantages: (1) small friction coefficient, high transmission efficiency, the transmission torque is small. (2) the high sensitivity, stable transmission, is not easy to produce, with precision and high positioning precision. (3) wear small, long service life, good accuracy stable. (4) can be eliminated by preloaded and clearance measures to improve the axial stiffness and reverse accuracy. (5) motion is reversible. Ball screw pair of faults: manufacturing complex, high cost, in the vertical installation cannot be self-locking, so need additional braking mechanism.
