The main difference between the main difference between a ball screw and trapezoidal screw and trapezoidal screw Ball and between is the way to move between the bearing surface of the load. Recirculating ball bearing ball screw using a ball screw, in order to minimize friction and facilitate efficiency, and trapezoidal screw is to use a low coefficient of friction between the sliding surfaces. Therefore, the high trapezoidal screw ball screw is usually not efficient. Analysis of tribological mechanisms can find: sliding friction predictability certainly lower than using recirculating ball drive technology. Fatigue life equation (such as L10 life) within its scope of application is very reliable. Based on the above, we can know the ball screw and trapezoidal screw is because the ability to predict performance and life is different, so the applications are quite different. Although Ball has more advantages (load, stiffness, efficiency, duty cycle, predictability), but the cost is relatively high. Although linear motion solutions, and other translational contrast, their high cost, but because of the ball screw design is more complex than it needs to hardened precision ball bearing surface, and a circulation device. The trapezoidal screw size is small, it is very flexible design, in the case of normal use very little noise, corrosion resistance, and can be applied in order to meet the needs of the vertical configuration of the self-locking feature. They play an important role in many applications, of course, itself also has some limitations. Specialized in ball screw and linear guide (HIWIN ball screw manufacturers, PMI, TBI, ABBA) notes, because the structure of each company's needs are not the same, the above picture is for reference only need to provide in-kind to our products prevail. Final Products offered by Foshan interpretation Kee building automation equipment Limited. DN value determines the maximum speed of the ball screw at rated load, mainly the following aspects of factors. 1. raceway hardness. Raceway shapes such as single or double circular arc. 2. nut raceway affect hardness. Dimensional network technology forums; O "} 3 Q. G8 P7 ^:.. Influence R. k 3. reverse back to the structure and shape of the bead and lifetime 4. 5. pitch assembly quality effects such as rigid spheres Optional 6. rigid spheres quality. hardness and small cracks (whether detection). In DmN value to evaluate high speed ball screw, Dm is the center of the upper and lower balls of the ball screw circle diameter (PCD), N is the maximum screw the number of rotations, so DmN value represents the revolution speed of the ball, DmN value is the speed limit of the ball screw design. For convenience, in order to replace the screw diameter D Dm. In 50ψx 30 Ball, when the wire The maximum number of bars when turning 3000rpm, DN value of up to 150,000, the maximum feed rate of 90 m / min professional to do the ball screw and linear guides (HIWIN Taiwan TBI ball screw, PMI, TBI small lead ball screws, ABBA) notes, due to the structure of each company's needs are not the same, the above picture is for reference only need to provide in-kind to our products prevail. interpretation of the final product offered by Foshan City, built-kei Automation Equipment Co., ball screw manufacturers, Regards build automation (certified), ball screw is provided by Foshan Kee building automation equipment Limited.
