From the first design to the finished product – fast and competent solutions
In spite of the use of advanced development tools, ever shorter development cycles from the first draft to the finished prototype involve some risk of assemblies being designed with extremely time-consuming and labor-intensive balancing procedures. Over and over again, our customers present us with this sort of problem – be it a crankshaft, an electric armature running at high speed, or an automatic fan.
For us at Schenck RoTec, cost-efficient balancing starts with optimizing the vibratory behavior of a rotor. By calculating the behavior of the rotor and its bearings with the help of the finite-element method, we can provide you with a wealth of knowledge for designing your rotors or assemblies. This will prevent unpleasant surprises with regard to the vibratory behavior of your work-pieces, and render design and production more cost-efficient – enhancing the performance of your products.
Putting theory into practice
The moment of truth comes when the first prototype of your design work is finally complete. Will your assumptions, ideas and calculations turn out to be correct? Will your prototype behave as expected, or will you have to improve certain details?
In our test shop, we can analyze how your rotor or assembly will behave in actual operation. In the event that measured results do not meet your performance specifications, we will make suggestions as to how your product can be improved. We will help you to reduce tolerances and mounting accuracies to a reasonable and economically tolerable level, or to simply define the best solution for balancing.
Basic principles of balancing in production
For many rotors, the decision as to what stage of rotor production is best for balancing is easily answered: Balancing is typically the last step in production, and essential for ensuring a low level of vibration.
For complex rotors consisting of several subassemblies, balancing is one of many steps in production, and the question as to when the rotor should be balanced is not so easy to answer. Further questions arise. Do you need to balance the individual parts of the rotor, and, if so, how accurately? What tolerances should be specified, given both technical and economic considerations? The right sequence of production steps and optimum design of the balancing processes will help to contain production cost.
