Designing Double Reduction Gear Drive: Input RPM 730, Output RPM 85.7
the steel you mentioned that is 29310 ultra-high strength steel is double quenched...while finding the bending strength we require the surface factor which is based on a graph where we measure the surface factor using harness number and whether the steel is forged, hot rolled or machined. So i...- fahadiliciouz

Designing Double Reduction Gear Drive: Input RPM 730, Output RPM 85.7
well my design is theoretical so pitting resistance is not included. u just have to find factor of safety using bending strength and bending stress... according to what u said that changing materials would resolve the problem so can u suggest a material which can b used for gears and which has a...- fahadiliciouz

Designing Double Reduction Gear Drive: Input RPM 730, Output RPM 85.7
yes it is based on AGMA standards i used AISI 1050 steel which is hot rolled.. pitch diameter according to the values i gave you is 54 mm for the pinion and 159mm for the gear and the face width is 60mm. what i was thinking was to use a steel which has a higher tensile strength compared to what...- fahadiliciouz

Designing Double Reduction Gear Drive: Input RPM 730, Output RPM 85.7
i have to design a double reduction gear drive using a spur gear pair.Input RPM is 730 and output RPM is 85.7. s The pinion teeth are 18 and the module is 3. The problem is that the input torque is 144Nm due to which i am getting a very high tangential velocity (Ft) which results in a higher...- fahadiliciouz
