Durable ball roller screw
Ball screw is the most commonly used transmission components of tool machinery and precision machinery, composed of screw, nut, steel ball, preloaded sheet, reverse device, dustproof device, its main function is to convert rotational motion into linear motion, or torque into axial repeated force, at the same time with high precision, reversible and efficient characteristics. Because of its low friction resistance, ball screws are widely used in various industrial equipment and precision instruments.
PYG- ball screw is based on the accumulated product technology of many years, and materials, heat treatment, manufacturing, from inspection to shipment, are managed by strict quality assurance system, so it has high reliability. Ball screw has higher efficiency than sliding screw, requiring less than 30% torque. It is easy to convert straight motion into rotary motion. Even if the ball screw is prepressed, it can maintain the smooth runing characteristics.
1. small friction loss, high transmission efficiency
Because there are many balls rolling between the lead screw shaft and the lead screw nut of the ball screw pair, higher motion efficiency can be obtained.
2. high precision
Ball screw pair is generally produced with the highest level of mechanical equipment in the world. Especially in the grinding, assembly and inspection of the factory environment of each process, the temperature and humidity are strictly controlled. Due to the perfect quality management system, the accuracy is fully guaranteed.
3. High speed feed and micro feed
Because ball screw pair uses ball movement, the starting torque is very small, there will be no crawling phenomenon like sliding movement, which can ensure the realization of precise micro-feed.
4. High axial stiffness
Ball screw pair can be added and prepressed, because the prepressure can make the axial clearance reach negative value, and then get higher rigidity (by adding pressure to the ball in the ball screw, in the actual use of mechanical devices, due to the repulsive force of the ball can make the rigidity of the silk master
5. can not self-lock, reversible transmission
