Ball screw drive nut screw drive in addition to general characteristics of the (slow down transmission ratio large and traction) outside Dongguan where Rotary Ball Screw, compared with the sliding screw drive, with the following characteristics: 3) Transmission reversible resistance, no sliding screw ball screw nut rotating viscous friction precision ball screw, eliminating the creeping phenomenon that may occur in the transmission process, the ball screw drive can be achieved in two ways ━ rotary motion into linear motion or linear motion into rotary motion and transmits power. 4) Long service life, due to the screw-shaped raceway accuracy, surface hardness, material selection and other aspects to be strictly controlled, ball real life is much higher than the sliding screw vice. 5) synchronization performance is good nut Rotary, since the ball screw running smoothly, eliminate axial clearance and consistency Shenzhen, where Rotary Ball Screw, the use of multiple sets of ball screw drive the same program or device manufactured When identical parts, get a good synchronization. Rotary ball screw nut Features: Vice ball screw drive efficiency up to 90% to 98%, the sliding screw pair of 2-4 times the torque can be efficiently converted into thrust, or thrust into torque. Point contact ball screw rolling friction, friction is small, sensitivity, and no vibrate when you start, low speed without crawling, may μ level control micro-feed. Ball screw drive the process temperature is small, can eliminate axial clearance and preload primary elastic deformation, the screw can be pre-stretched to compensate for thermal elongation, so the availability of high positioning accuracy and repeatability of positioning accuracy . Ball and roller hardness HRC58 ~ 63, the exact shape of the raceway, minimal rolling friction and wear, has good retention precision, reliability and service life. Ball deputy inside and outside corner raceway are double eccentric circular surface, the raceway small gap can be flexible when driving. Add some preload can be eliminated if desired axial clearance and primary elastic deformation in order to obtain a good rigidity (in this case the life of a decrease).
