The structure of the caster

The structure characteristics of castor castor is made from a single wheel is installed on the bracket, used to install below the equipment makes it free to move. Castor is divided into two main categories: A fixed castor: fixed bracket with single wheel, only move along A straight line. Turning the B universal casters: 360 degrees with single wheel, can run freely in any direction. Installation height: refers to from the ground to the vertical distance between equipment installation position, the installation of the castor height refers to remote the largest vertical distance and castor base plate and the wheel. Stand to center distance: refers to the vertical line to the center of the wheel core center rivet horizontal distance. Turning radius: refers to the center of rivet vertical line to the outside of the tire on the edge of the horizontal distance, proper spacing of the caster wheel can be turned 360 degrees. The turning radius is reasonable or not directly affects the service life of the 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 castor instantaneous load bearing capacity. Static load and static load static load and static load: castor 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. To: 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. Driving flexibility: factors affecting driving 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!
