Installation and application of industrial rubber casters

Casters can be called directional casters and swivel casters. The directional caster bracket is equipped with a single wheel, which can only move in a straight line. The universal caster is composed of a bracket that can turn 360 degrees and a single wheel, which can move in any direction at will.

Installation height of industrial rubber casters: refers to the vertical distance from the ground to the installation location of the equipment, and the installation height of casters refers to the vertical distance from the bottom of the caster and the edge of the wheel. Bracket steering center distance: refers to the horizontal distance from the vertical line of the center rivet to the center of the wheel core.

Turning radius: refers to the horizontal distance from the vertical line of the center rivet to the outer edge of the tire. The appropriate distance enables the caster to turn 360 degrees.

Whether the turning radius is reasonable or not directly affects the service life of the caster.

Steering: Hard, narrow wheels are easier to steer than soft, wide wheels. The turning radius is an important parameter for wheel rotation. If the turning radius is too short, it will increase the difficulty of steering, and if the turning radius is too large, it will cause the wheel to shake and shorten its life.

Driving flexibility: The factors that affect the driving flexibility of casters include the structure of the bracket and the selection of steel for the bracket, the size of the wheel, the type of the wheel, the bearing, etc. The larger the wheel, the better the driving flexibility, and it is hard and narrow on a stable ground. The wheel is more labor-saving than the flat-edge soft wheel, but the soft wheel is labor-saving on uneven ground, but the soft wheel can better protect the equipment and absorb shocks on the uneven ground.

Driving load: The load-bearing capacity of the caster when moving is also called the dynamic load. The dynamic load of the caster varies due to the different test methods of the factory and the material of the wheel. The key is whether the structure and quality of the bracket can resist shock and impact. shock.

Shock load: The instantaneous load-bearing capacity of the caster when the equipment is impacted or vibrated by the load.

Static load: The weight that the caster can bear in a stationary state. The static load should generally be 5 to 6 times the exercise load (dynamic load), and the static load should be at least 2 times the impact load.

How to distinguish the quality of casters:

1. From the appearance of the caster bracket, the steel plate bracket of the caster has a beautiful surface, no burrs, and the thickness must be uniform, thus ensuring the quality of the load;

2. Galvanized caster bracket: In order to prevent rust, the bracket is generally galvanized. Check that the galvanization of the caster bracket should be uniform and shiny;

3. Welding of caster brackets: The welding of steel plates should be smooth, and there should be no leakage welding, leakage points, etc.;

4. The size of the commonly used wheels for casters;

5. Check the appearance of the caster: smooth surface, no bumps, uniform color, no obvious color difference;

6. Check the overall effect of the universal wheel: when the top plate rotates, each steel ball should be able to contact the surface of the steel plate, the force should be uniform, the rotation should be flexible, and there is no obvious pause.

7. Check the bearing quality of the caster: there should be no obvious jumping phenomenon when the caster rotates
