DFV Series Ball Screw Made in China for CNC machine
Ball screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force. It also has high precision, reversibility and high Features of efficiency. Because of its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments.
The ball screw is composed of a screw, a nut, a steel ball, a pre-compression piece, a reverser, and a dustproof device. Its function is to convert rotary motion into linear motion, which is a further extension and development of Akem screw. The important meaning of this development is to change the bearing from sliding motion to rolling motion.

In order to adapt to various purposes, ball screw bearings provide a wide range of standardized products. Widely used in machine tools, the ball circulation methods include circulating duct type, circulator type and end cap type. Preloading methods include positioning preloading (double nut method, position preloading method) and constant pressure preloading. The appropriate type can be selected according to the purpose. The screw has high-precision grinding precision ball screw (precision is divided into 6 grades from CO-C7) and cold-rolled ball screw bearing formed by high-precision cold rolling (precision is divided into 3 from C7-C10) Levels). 게다가, in order to cope with the urgent need for delivery by users, there are finished products that have been processed on the end of the shaft, semi-finished products and cold-rolled ball screw bearings that can be freely processed on the end of the shaft. As the peripheral parts of this bearing, the screw support unit, nut support, lock nut, 등. necessary for use have also been standardized and can be used by users.
Ball screw bearings are based on product technology accumulated over the years. From materials, heat treatment, manufacturing, inspection to shipment, they are managed by a rigorous quality assurance system, so they have high reliability.
풍모
1. 낮은 마찰 손실 및 높은 전송 효율 [4]
볼나사 쌍의 나사축과 나사너트 사이의 구름운동에는 볼이 많기 때문에, 더 높은 운동 효율을 얻을 수 있습니다. 이전 슬라이딩 나사 쌍과 비교, 구동 토크는 다음보다 작습니다. 1/3, 그건, 동일한 모션 결과를 달성하는 데 필요한 전력은 1/3 슬라이딩 나사 쌍의. 절전에 매우 유용.
2. 높은 정확도
볼스크류는 일반적으로 세계 최고 수준의 기계 및 장비로 지속적으로 생산됩니다.. 특히 연삭 공장 환경에서, 집회, 및 검사, 온도와 습도는 엄격하게 통제됩니다. 완벽한 품질 관리 시스템으로 인해 정확성이 완전히 보장됩니다..
3. 고속 이송 및 미세 이송 가능
볼 나사 쌍은 볼 운동을 사용하기 때문에, 시동 토크가 매우 작습니다., 슬라이딩 모션과 같은 크롤링 현상이 없을 것입니다., 정확한 마이크로 피드의 실현을 보장할 수 있는.
4. 높은 축 강성
볼 나사 쌍은 미리 로드될 수 있습니다. 예압이 축방향 간격을 음의 값에 도달하게 할 수 있기 때문에, 그런 다음 더 높은 강성을 얻으십시오. (볼 나사에서, 볼에 압력이 가해지면. 실제로 기계 장치에 사용되는 경우, 볼의 반발력으로 인해 너트의 강성이 증가 할 수 있습니다.).
5. 자체 잠금이 불가능하고 전송의 가역성이 있습니다.
