Germany (IF) Fu billion Ball features high speed through sophisticated design, precision ball screw friction is extremely small, so that the machine can run at high speed, heavy-duty high speed to adapt to today's needs. That high rigid preload eliminate axial clearance between the screw and nut, it is necessary to use it for ball screw. While doing so the friction a little improved, but needed to obtain high drive rigidity, while the return axial clearance so greatly reduced. Special design and operation of process precision ball screw will meet the customer's rigid requirements to provide accurate ball screw pretension after. Based on the above characteristics and reversible sliding screw ball screw no viscous friction, eliminating possible creep phenomenon in the transmission process, precision ball screw drive can smoothly implement two ways - into rotary motion linear motion or linear motion into rotary motion of the ball screw, passing within this power recirculating ball screw ball screw circulation patterns have inner loop (with circular and elliptical inverter inverter as the representative) and the outer loop (with intubation represented) two. These two structures is the most commonly used structure. These two structural performance is no essential difference, but the inner loop structure installation and connection of small size; outer loop structure is mounted to connect large size. At present, the structure of the existing 10 kinds of ball screw, but the more common are the following: the cover ring (a); external circulation (b); internal circulation (c); cover ring (d). ① circulating ball during the cycle, always keep in contact with the screw surface circulation, called the inner loop. Advantages inner loop structure is: the smaller dimensions of the ball screw nut, inverters stable fixation, rigid and easy to wear; Ball reverse channel is short, less the number of balls, smooth and good, small friction loss, high transmission efficiency. The disadvantage is that can not be made long ball screw thread ball screw Guangzhou, inverter back bead groove is curved coordinate space, processing is more complex. ② outer loop is the ball outside the circle in the cycle, it can not remain in contact with the screw surface Hengshui Ball, that is, when the ball raceway from the threaded end reverse to the beginning of the end when the raceway surface out of contact with the screw. Outside the circle can be divided into: intubation, spiral trough and cover three. Outer loop structure manufacturing process is simple, high carrying capacity, but pipeline welding is difficult to achieve smooth, affect the smoothness of Wuxi ball rolling ball screw, or even imagine card beads, size large, the noise is large, poor wear resistance . Loop structures within the ball circulation circuit through an inverter, each consisting of an inverter circle ball chain, so a small carrying capacity, at high speed when the ball fluency poor adaptation to micro ball screw and ball screw ordinary deputy, but nut size is relatively small.
