Here are the primary design considerations:\n\nMechanical Design Requirements:\n\nFunctionality: Ensure the crankshaft design meets the functional requirements of the engine or mechanical system it is intended for.\nStrength and Durability: Crankshafts experience high mechanical stresses due to cyclic loading. Ensure the material selection and cross-sectional dimensions can withstand these stresses without failure.\nBalancing: Proper balancing is crucial to minimize vibrations and ensure smooth operation. SolidWorks can simulate dynamic forces and moments to optimize the crankshaft's balance.\nMaterial Selection:\n\nChoose a material that balances strength, toughness, and machinability. Common materials include alloy steels such as AISI 4340 or 4140, which offer good strength and toughness properties suitable for crankshaft applications.\nGeometric Design:\n\nMain Journal and Crankpin Design: The main journals and crankpins must be designed with appropriate diameters and lengths to support the bearings and withstand the applied loads.\nFillets and Radii: Smooth transitions and generous fillets between different sections reduce stress concentrations and improve fatigue resistance.\nOil Passages: Ensure adequate oil passages to lubricate the bearings and journals. SolidWorks allows you to model these passages accurately to ensure proper lubrication flow.\nManufacturability:\n\nConsider the manufacturability of the crankshaft design. SolidWorks can assist with creating detailed manufacturing drawings and simulations to validate manufacturing processes such as machining, heat treatment, and surface finishing.\nPay attention to draft angles, tool access, and tolerances to facilitate machining operations.\nAnalysis and Simulation:\n\nUse SolidWorks Simulation tools to perform stress analysis, fatigue analysis, and modal analysis to ensure the crankshaft design meets safety factors and durability requirements.\nDynamic analysis can help optimize the crankshaft design for reduced vibrations and improved performance.\nAssembly Integration:\n\nEnsure the crankshaft design integrates correctly with other engine or mechanical system components. SolidWorks allows you to model assemblies and perform interference checks to verify fit and function.\nDocumentation:\n\nCreate detailed engineering drawings with SolidWorks to communicate the crankshaft design specifications, dimensions, tolerances, material specifications, and surface finishes to manufacturing.\nBy addressing these considerations in SolidWorks, you can create a crankshaft design that meets functional requirements, ensures durability, and is optimized for manufacturing and assembly processes.","imageAlt":"Crankshaft 3d model design editable part","url":"https://www.cgtrader.com/3d-print-models/science/engineering/crankshaft-3d-model-design-editable-part","isCLDApplicable":false,"isSaleOffApplicable":true,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/fAECt2YeekxNUxMAy66dQAbF/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/Crankshaft1%5B1%5D.jpg","gridUrl":"https://media.cgtrader.com/variants/fAECt2YeekxNUxMAy66dQAbF/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/Crankshaft1%5B1%5D.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-print-models/science/engineering/crankshaft-3d-model-design-editable-part","isCgtVerified":false,"types":{"printReady":true,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":29,"name":".ige","is_native":false}],"categorySlug":"science","subcategorySlug":"engineering","categoryTitle":"Science","subcategoryTitle":"Engineering","schemaImageUrl":"https://img-new.cgtrader.com/items/5401205/fb6ef4f5a0/crankshaft-3d-model-design-editable-part-3d-model-fb6ef4f5a0.webp","saleOffDiscount":50,"eligibleForSubscription":true,"subscriptionSubscribed":false,"subscriptionPotential":true}},{"id":"85066","type":"listingItem","attributes":{"id":85066,"title":"3D Printable Crankshaft","price":5.0,"description":"\u003cp\u003eNeed a complex mechanical part?\r\nNothing like a W12 engine Crankshaft to do the job!\r\nThis engine is designed after the VolksWagen W12 Engine, 3D printable and ready to go.\r\nNote: This model is in full scale, which may be very big to print, you'll want to scale it down to be able to print it.\u003c/p\u003e","imageAlt":"3D Printable Crankshaft","url":"https://www.cgtrader.com/3d-print-models/science/engineering/3d-printable-crankshaft","isCLDApplicable":false,"isSaleOffApplicable":true,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/w471V8fzY6JJBJcCJ3QEa7Ae/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/3d-printable-crankshaft-3d-model-stl.jpg","gridUrl":"https://media.cgtrader.com/variants/w471V8fzY6JJBJcCJ3QEa7Ae/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/3d-printable-crankshaft-3d-model-stl.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-print-models/science/engineering/3d-printable-crankshaft","isCgtVerified":false,"types":{"printReady":true,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":null,"name":null,"is_native":false},{"id":51,"name":".stl","is_native":false}],"categorySlug":"science","subcategorySlug":"engineering","categoryTitle":"Science","subcategoryTitle":"Engineering","schemaImageUrl":"https://img-new.cgtrader.com/items/85066/02f815d91f/3d-printable-crankshaft-3d-model-02f815d91f.webp","saleOffDiscount":50,"eligibleForSubscription":false,"subscriptionSubscribed":false,"subscriptionPotential":false}},{"id":"125087","type":"listingItem","attributes":{"id":125087,"title":"Automotive crankshaft","price":7.95,"description":"A crankshaft is a shaft driven by a crank mechanism, consisting of a series of cranks and crankpins to which the connecting rods of an engine are attached.[1] It is a mechanical part able to perform a conversion between reciprocating motion and rotational motion.

This is simply a different way of building the short block of an engine...with many advantages..such as reduced friction..smaller size..far less moving parts, higher revs, more power, and so on. This concept could be used in engines of any size or cylinder number..even a one cylinder configuration is possible. I left out the main crankshafts counter weights in my animation so that the concept could be shown clearer, also an engine built in a 4 cylinder or configuration would be much easier to balance. And here are the technical specs....... There would be one or two ring gears (with teeth numbering 2x) attached to or part of the pistons surrounding the crankshafts with their diameter equal to the throw of both crankshafts combined or (2y). One or two gears (with teeth numbering x and diameter equal to y) attached to the primary crankshaft affixed to the rod journal so that they ride inside of the ring gear(s). The main crankshaft and secondary (or eccentric lobe) will have the same offset, therefor if each crankshaft has a throw of two inches the pistons would then travel a total of four inches. The engine would have a minimum of two pistons, each set of opposing pistons are bolted together, making one solid unit. This engine would have opposing pistons similar to a Boxer engine configuration, with the exception that the pistons are directly across from one another. The cylinders and heads will work the same as they do in a conventional engine. The benefits of this design; There are no connecting rods. So the engine should be able to withstand much higher RPMs than a conventional engine. This design also insures that the pistons will stay in-line with the cylinders, and therefor reducing friction. There are also less moving parts, a 4-cylinder engine built using this design would have only 5 moving parts in the short block, as opposed to the 9 moving parts found in conventional 4-cylinder engines. Components; A. The crankshaft, a standard looking engine crankshaft, with the exception of the gear(s) permanently affixed to the rod journal, with teeth numbering x. The diameter of the gear(s) is equal to the throw of the main crankshaft or y. B. The secondary crankshaft, or eccentric lobe is round with an offset hole that the main crankshafts (A) rod journal rides in. C. The pistons, which when bolted together form one solid unit from piston to piston. . They have a hole in the middle where the main (A) and secondary (B) crankshaft ride. D. Ring gear(s), with teeth numbering 2x. The gear(s) that are affixed to the main crankshaft (A) ride inside this ring gear(s). The diameter or the ring gear(s) is equal to the throw of both crankshaft and eccentric lobe combined or (2y).
