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 is used, 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 Foshan wholesale Ball in many application areas, of course, itself also has some limitations. Specialized in ball screw and linear guide (HIWIN, PMI, TBI, ABBA) notes, because the structure of each company's needs are not the same, the above picture is for reference ABBA ball screw a supplier, you need to provide in-kind to our products . whichever interpretation of the final product by Foshan Kee building automation equipment Limited offers ball screw screw-rust: for reference purposes only! First, the object to be surface rust pretreatment 1) Surface cleaning: cleaning must be in accordance with the nature of the surface rust-proof and prevailing conditions, the appropriate method is selected. Commonly used solvent cleaning, chemical treatment and mechanical cleaning method to clean. 2) the surface is dry cleaned by filtration is dried compressed air, or a dryer with 120 ~ 170 ℃ is dried, dry clean gauze can also be used. Second, anti-rust oil coating a) immersion method: Some small items using soaked in anti-rust oil, allowed to adhere to the surface layer of rust grease approach. The film thickness can be achieved by controlling the temperature or viscosity antirust oil. 2) large-scale anti-rust spray some things can not be used immersion oiled, usually about 0.7Mpa pressure spray compressed air filters in the air cleaner place. Spray application of solvent dilution type rust oil or thin layer of rust oil, but must be used to improve fire safety and labor protection measures. 3) brushing method for NA immersion or spray outdoor construction equipment or special shape products, it is necessary to pay attention to when brushing no accumulation, but also pay attention to prevent leakage Tu.
