Welcome to mechanicalcheck.com - the worlds easiest online calculator for drive shafts, parallel keys, etc.! All calculations are performed according german standard DIN, operation is intuitive. It's worth a try!
Up to now many standards have been realized. A shaft stress analysis is performed according standard DIN 743 while the load capacity of parallel keys is calculated according standard DIN 6892. Now two new standards have been added: Standard DIN 6885 for dimensions of parralel keys and DIN EN 10025 for material properties of structural steels.
Standard DIN 743 is the industrial standard for calculation and proof of load capacity of shafts and axles. It is a tool for engineneers that covers almost all applications. Thus many influences are considered. Size of mechanical component, heat treatment and machining have a great impact on strength of the material. Further the influence of increased stress at notches and the influence of load combinations on the allowable stresses is considered.
Standard DIN 6892 and DIN 6885 are used for parallel keys. Dimensions and shapes are described in DIN 6885, the proof of load capacity in DIN 6892
Standard DIN EN 10025 desribes the material properties of structural steels. Just select the steel, the database of the online calculator will provide yield strength, tensile strength, elongation at rupture and Charpy impact energy!
