The structure characteristics of medium-sized castor analyses castor manufacturer
Medium-sized castor castor manufacturers to the structure characteristics of medium-sized castor is analysed according to the material classification can include: nylon, polyurethane PU, TPR, PP, rubber materials, because the material is different, it belongs to medium casters series, but bearing range is different. Medium-sized castor by type classification can include: easy startup wheel, backplane activity type/stationary, stainless steel plate, hollow rivet, screw type, rod type, with the brakes several types, including floor it flattened, tubular rivet type is called a hole type. Medium-sized castor industry general or the United States called direct route round 2 series, they both in material and the type is according to the above, the different material, type, applied in different environment, bearing, choose suitable castor is very important. 1, installation height: refers to from the ground to the vertical distance between equipment installation location, installation height, it refers to a medium of medium-sized castor castor base plate and the wheel remote maximum vertical distance. 2, support to center distance: refers to the vertical center rivet's horizontal distance to the center of the wheel core. 3, the rotation radius: refers to the center of the rivet vertical line to the outside of the tire on the edge of the horizontal distance, proper spacing of the medium-sized castor can be turned 360 degrees. Turning radius is reasonable or not directly affects the service life of medium-sized castor. 4, driving load, medium casters moving load bearing capacity is also called dynamic load, dynamic load of medium-sized castor is different due to the test in a different way of the factory, the material of the wheel will have different and different, the key is to support the structure and quality can impact and shock resistance. 5, impact load: when the equipment has fundamental impact or vibration of medium-sized castor instantaneous load bearing capacity. Static load and static load static load and static load, medium casters can bear the weight of the under stationary state. Static load generally should exercise load ( Dynamic load) 5 ~ 6 times, static load should be at least 2 times the impact load. 6, steering: hard, narrow wheel than soft, wide wheels turn more easily. Rotate wheel radius is one of the important parameters, short turning radius increases to the difficulty, too much will cause the wheels wobble and shorten the life. 7, driving flexibility: factors affecting driving medium castor flexibility with stents of the structure and the selection of steel, the size of the wheel, wheel type, bearing, wheel driving the greater flexibility, the better, hard on the smooth ground, narrow wheel than flat soft wheels and effort, but on the uneven ground soft wheels and effort, but on the uneven ground soft wheels can better protect device and shock!
