Structure of the structure of the castor castor manufacturer
Castor manufacturers of castor castor tectonic structure is usually composed of stents and wheels, that is, single wheel.
Bracket is metal, but also have plastic, plastic stents we often call it all plastic, general medical industry, with more round and furniture industry is also plastic stents more.
And in our industry with the most is of course the metal stents.
One can be called a directional casters, caster and universal casters.
Directional casters with single wheel on a support, can only move along a straight line.
Universal caster wheel is made up of 360 degrees to stent with single wheel, can freely move in any direction.
Second, installation height: refers to from the ground to the vertical distance between equipment installation location, 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.
Three, the rotation 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.
Four, steering: 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.
Five, 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 suspension.
Six, 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.
Seven, impact load: when the equipment has fundamental impact or vibration castor instantaneous load bearing capacity.
Eight, static load: castor can bear the weight of the under stationary state.
Static load generally should exercise load (
5 ~ 6 times, static load should be at least 2 times the impact load.
Castor structure is very simple, but if you want to more in-depth to use it to know a lot about it, so the above eight from the extension of the caster wheel structure, the same which is formed by castor formula;
Every castor production and selection is to follow the formula to work.
