Experimental measurement of transmission error and vibration of a gear pair with crown modification are developed. With the help of high-precision optical encoder. effects of gear misalignment on unloaded and lightly loaded dynamic transmission error. which are relative to gear rattle. https://www.roneverhart.com/HP-Pavilion-15-eg2373cl-15-6-FHD-Touch-Laptop-Intel-Core-i7-1255U-3-50-GHz-GeForce-MX550-16GB-DDR4-512GB-SSD-Windows--p8309/
