Direct ball screw Jinan - Jinan Special Precision Transmission Co., Ltd. 1 Ball Series Type: SFI SFI and DFI models of consistency a lot. 2.Ball Series Model: DFI 3.Ball Series Model: SFU 4.Ball Series Model: DFU 5.Ball Series Model: SFT 6.Ball SeriesModel: DFT
ball screw is rotary motion into linear motion, or linear motion into rotary motion of the desired product.
ball screw by the screw, nut and ball composition.Its function is to transform the rotary motion into linear motion, ball screw which is a further extension and development, the significance of this development is to slide the bearing into the action from the scroll action.With little friction, ball screws are widely used in various industrial equipment and precision instruments.
machine tools and precision ball screw is the most commonly used on mechanical transmission components, its main function is to convert rotary motion into linear motion or torque into axial force over and over again, while both high-precision, reversibleand high efficiency characteristics.
Feature
(1) compared with the sliding screw drive torque vice 1 / 3
As the ball screw of the screw shaft and ball screw nut are doing a lot between the rolling motion, so the campaign can get higher efficiency.The past compared to the sliding screw drive torque to vice 1 / 3, to achieve the same movement that the power needed to use the results of rolling screw pair 1 / 3.Was helpful in saving.
(2) to ensure high-precision
Ball screw is manufactured in Japan the world's highest level of consistent production out of the machinery and equipment, especially in the grinding, assembly, inspection of the process plant environment, the temperature and humidity were strictly controlled, due to improved quality managementsystem so that accuracy can be fully guaranteed.
(3) micro-feed may
As the ball screw is the use of ball movement, so the starting torque is extremely small, sliding motion does not appear as crawling phenomenon, to ensure the accurate micro-feed.
(4) no backlash, high rigidity
Ball screw can be added to the pressure, due to the axial clearance can achieve negative pressure, and thus receive higher rigidity (by giving the ball within the ball screw to increase the pressure in actual use mechanical devices, due to ballThe repulsion can enhance the rigidity of the Department of silk mother).
(5) high-speed feed may
Ball screw, sport, high efficiency, small heat, so we can achieve high speed
