Castor overall introduction
Castor is a general designation, including activities and directional casters, castor also is what we call universal wheel, main function is allowed to rotate 360 degrees, fixed castor also called directional wheel, no rotational structure, cannot turn, often match two casters are generally used. Such as the structure of the trolley is two feet in front of a fixed, back near the armrest is driven by two wheels. How to select suitable castor? Installation height: refers to from the ground to the vertical distance between equipment installation location, with castor castor installation height refers to the base plate and the wheel edge of the largest vertical distance stents turned to center distance, refers to the center of the rivet vertical horizontal distance to the center of the wheel core 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 caster wheel can be 360 degree turn, turning radius is reasonable or not directly affects the use of castor. Driving load: castor moving load bearing capacity is also called dynamic load, dynamic load of the 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. Impact load: when the equipment has fundamental impact or vibration caster moment generally should exercise the load bearing ability of static load ( Dynamic load) 5 ~ 6 times, should be the impact of negative charge 2 times at least six. To: hard, narrow wheel turned to more easily than the wheels of the soft, wide, 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 castor flexibility with stents structure and steel, choose to use, the size of the wheel, wheel type, bearing, wheel driving the greater flexibility, the better, in a flat on the ground hard, narrow wheel than flat soft wheels and effort, but on the uneven ground soft wheels and effort, but soft on uneven ground wheel suspension can better protect equipment. / news_129。
