<p>Our employer Camatec Industriteknik AB gave us the assignments to increase theirs range of versions on Camcoil that is their own patent product. Camcoil is a capstan system that is used when steel band fabricated. Exist for example in production lines their steel band should be annealed. Our goal with this work is to come up with a completed production basis on a Camcoil for heavy industry. The basis should contain calculations, 3D-constructions, drawings and cost proposal on manufacturing and detail purchase.</p><p>Demands on this project:</p><p>1. 15 ton load</p><p>2. Strip width up to 1500 mm</p><p>3. Head diameter 610 mm</p><p>4. Production speed 35 m/min</p><p>5. Economy manufacturing</p><p>6. Be simple</p><p>Several concepts were decided out of the feasibility study. The concepts were compared against each other and finally only one was left. Result of the design concept became one shaft with three capstan heads and a support function.</p><p>One conceivable working process was planed with a Gantt-table. A decision was made that the work of the Camcoil should be separated in several details. Earlier work on Camcoil was study to increase our understanding for the work.</p><p>Some of the examined parts were shaft dimensions, bearings, head shape, tripod, support function and hydraulic cylinder for the capstan and support.</p><p>Some of the calculations have been made in Ansys. Directional deformation, Von Mises stress for the shaft, length of the hydraulic cylinder in the capstan heads and the stress for tripod and support function was calculated.</p><p>Analytic calculations were made on some parts. Frequency analysis for the system was made with Dunkerleys method. The reaction forces in the bearings were calculated with a combination of elementary case. Lifecycle of the bearings can with this be appreciated. Hydraulic cylinder strength in capstan heads and support function, locking assemblies, sheet metal thickness and control off beam dimensions in support was also decided with analytic calculations.</p><p>3D models were made on several details in the system. Models like lock rings, engines and bearings were taken from the supplier.</p><p>After the modeling assemble drawings and detail drawings were made for the whole capstan system. The drawings were sending to manufacturer for a cost proposal.</p>
