DFV Type (High-speed ,heavy load ,Outer circulation,JIS standard nut)

Introduced:
1, the ball screw is used to convert the rotary motion into a linear motion; or the linear motion into the rotary motion of the implementation of the components of the ideal product.
2 when the ball screw as the active body, the nut will follow the rotation angle of the screw rod according to the corresponding specification of the guide path into linear motion, the passive workpiece can be driven by the ball screw, the ball nut.
Application:
Widely used in all kinds of industrial equipment, precision instruments, engraving machine, high speed CNC machine, window machine, semiconductor equipment, high-speed machinery and so on.
Characteristic：
1, compared with the sliding screw drive torque is 1/3
There are many balls between the lead screw and the screw of the ball screw, which can make the rolling movement, so it can get a higher efficiency. Compared with the past sliding lead screw drive torque to 1/3 below, that is, to achieve the same movement of the power required for the use of the power to use the rolling screw pair 1/3. Helpful in saving electricity.
2, high precision guarantee
Ball screw is made Japan the world's highest level of machinery and equipment coherence produced, especially in grinding, assembly, check the process of the factory environment, the control of temperature and humidity in the strict, due to perfect quality management system make the accuracy can be fully guaranteed.
3, micro feed possible
Because the ball screw rod is used for the ball movement, the starting moment is very small, and the creeping phenomenon of the sliding movement can not occur, and the accurate micro feed can be guaranteed.
4, no backlash, high rigidity
Ball screw can be added to the pre pressing, due to pressure the axial clearance can reach negative values, and get a higher rigidity (within the ball screw through to the ball and the pre pressure, when in actual use mechanical devices, due to the repulsive force ball can enhance the rigidity of the screw nut).
5, high speed feed possible
Because of high efficiency, low heat, the ball screw can realize high speed feed (movement).
