five keys to choosing the correct spring loaded casters in heavy duty industrial caster applications
Spring casters have always been the gold standard for noise reduction and protection of payload in manufacturing environments.
When choosing the right casters and Spring configuration, the results will be very predictable, achieving the planned noise reduction.
If the spring loaded casters are not designed properly and the Spring configuration is not designed properly, the results will not be satisfactory and may even increase the noise level in the manufacturing operation.
Three key factors must be evaluated before designing the appropriate spring loading casters.
To understand these three factors, we must first understand the three factors that occur in any spring. Initial force-
Each spring, no matter how small or large, has a measurable force that must be applied to the spring to cause a deflection of the spring structure.
Linear deflection
Once the Spring begins deflection, it is designed to provide a very predictable deformity of the spring structure with respect to the applied forces.
This is a linear relationship (
Linear projection in the associated graph)
And it is proportional, because at every point along this line, the force of X causes the deformity of Y. Full deflection-
At the end point, the spring is completely deformed as a response to the force, unless the pressure is so great that in fact the material made by the spring is deformed, no further pressure will change the spring.
When designing and manufacturing spring-loaded casters, it is important to consider that each of these features has a spring-loaded caster that works properly.
The spring has a variety of different properties that affect each of the three areas discussed.
Pre-load of spring-(Initial Force)-
In the engineering and manufacture of casters, there must be a pre-
The load applied to the spring.
In the chart provided, the pre-load force is about 250.
At this point, any additional force applied to the casters will result in spring deflection and noise reduction.
Any load applied to the casters under this pre-
The load will cause zero deflection.
Combat forces-
Linear deflection
In this area of the chart, the spring should work in a similar way to the theoretical deflection curve.
As you can see in the chart, for the entire length of the chart, each test case is executed in a very predictable way.
This means that the spring has a very predictable movement for each pound of force applied.
The picture also depicts the sweet spot of an operation that, through proper planning and full understanding of the operation, will \"live in this area\" in spring \".
If the engineering of the spring position and spring alignment is not applied correctly to the design, the final result will not be a linear diagram and the operation will not be optimal, most likely resulting in damage to the Mage, cart or payload. Bottom Out-Full deflection-
At this point, the caster is no longer a spring loaded caster, and the caster will act as a regular caster without any sound
Anti-sound effect.
Even in properly designed casters, this may occur when the impact loading of the trolley, the excessive loading of the trolley, or the obstacle or pot hole is encountered during operation.
If the \"bottoming\" process often occurs during normal operation, it is likely that the casters are not designed for the application.
