Avoid Unnecessary Roller Repair
In today’s manufacturing sector, many industrial rollers are being used outside the limits of their initial intended designs. Quite often, businesses are running their equipment, including rollers, faster and harder to increase production in an effort to boost their bottom line. Many times, the rollers and equipment are not meant to run at the speeds and loads they’re now running at. This may lead to roller repair being needed.
Menges Roller Company, along with its 50 years of experience in the industry, utilizes Finite Element Analysis (FEA) when designing new rollers to ensure the safest and most efficient design possible. With the goal in mind to test the load bearing capacity of any newly designed roller, FEA allows Menges Roller the ability to design a better all-around roller. If a roller does not utilize FEA analysis, roller repair is likely to be needed if the stress concentrations are not designed into the roller.
When using FEA in the design process of a roller you can identify both the amount and location of stress concentrations on shaft or journal. Plain and simple this eliminates roller repair or roller failure, this means lower material costs and less labor versus an approach that does not quantify the results of design changes. On the other hand, it also means you will not be receiving a roller that is prone to failure in operation. Combining the cost of downtime with the potential safety hazard repercussions of a broken shaft or journal during operation may be the two most important reasons FEA is so crucial.
In addition, FEA can be used to determine roller deflections under given loads (those seen in operation) for even the most intricate of roller designs. If an even nip is important to a given process, then understanding how different material types, sizes, and shapes influence deflection becomes increasingly critical. Once deflection is calculated, then it becomes an easy task to specify any crowning necessary on nipped rollers – yet another benefit of complementing any design process with FEA.
