Gearing Up
The objective of this project was to design a gear-train which could transmit motion and torque from shaft A to C. A power input of 7kW was provided by an electric motor operating at 1500 rpm and connected to shaft A by a flat belt transmission with a 1:1 ratio. The design maintained a speed-reduction error of less than 2% and was assumed to be 100% efficient overall. The reducer could be reliably expected to work for 5 years (52 weeks a year, 5 days a week, 8 hours a day) with minimal maintenance.
MATLAB was used to calculate (1) the number of teeth on pinion gears, (2) the forces on each shaft, gear and bearing, and (3) the minimum shaft diameter. My team used a custom code I wrote to quickly incorporate any design changes without having to manually recalculate every component. NX 8.0 was used to design the entire system and publish engineering diagrams of each gear train component, as well as the assembled device.
