Usually felt ring seal on the nut, the thickness of the felt ring is 2 to 3 times the pitch, and the shape of the hole made into thread to make it tightly wrap the screw and nut or sleeve into the ends of the groove hole. In addition to using a soft felt ring, you can also use oil and rubber or nylon material. Due to direct contact with seals and screw screw Shenzhen ladder ball screw, so dust is better, but also increases the frictional resistance of the ball screw nut torque. To avoid such friction torque, can be used by a hard plastic non-contact labyrinth seals, the hole formed with the screw thread roller screw Shenzhen opposite shape miniature ball screw, and leave some clearance. For the exposed screw, just with a general spiral, telescopic, cone sleeve and folding plastic or leather in the form of protective cover to prevent dust and abrasive particles adhered to the surface of the screw. In addition to the rails is similar to the outer shield, which is connected to one end of several shields the end face of the ball nut, the ball screw and the other end is fixed to the support base. This can be more firmly the. Product: ball screw, linear guides, linear modules, wire rod supporting, servo brand: HIMIN, PMI, TBI, ABBA notes, because the structure of each company's needs are not the same ball screw Shenzhen, above picture is only for reference, Real need to provide our products subject to final interpretation of the product offered by Foshan City Qi building automation equipment Limited. The main difference between the main difference between a ball screw and trapezoidal screw ball screw and trapezoidal screw is between between In carrying the load of way to move between the surfaces. Ball uses recirculating ball bearing, easy to minimize friction and efficiency, and lead screw is to take advantage of low coefficient of friction between the sliding surfaces. Thus, the high trapezoidal screw ball screw is usually not efficient. Tribological mechanism analysis can be found: sliding friction predictability definitely lower than using recirculating ball drive technology. Fatigue life equation (such as L10 life) within its scope 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 translational motion and other programs In contrast, their high cost, but because the ball screw design is more complex than it needs to hardened precision ball bearing surface, and a circulation device. The trapezoidal screw small dimensions, it is very flexible design Shenzhen ball screw specifications and price, in the case of normal use very little noise, good corrosion resistance, can in order to meet the needs of vertical applications and configuration lock function. They play an important role in many applications, of course, itself also has some limitations. Specialized in ball screw and linear guides (HIWIN, PMI, TBI, ABBA) notes, because the structure of each company's needs are not the same, the above picture is only for reference, you need to provide in-kind to our products subject to final interpretation of the product Foshan Qi building automation equipment Limited. nut ball screw rotary Shenzhen, Qi build automation (certified), Shenzhen, Foshan City, the ball screw is provided by Kee building automation equipment Limited.
