And we like hearing from our customers that it fits "just right". This is due to the fact that surfaces under high compressive load always deform significantly altering the contact area and therefore the resultant stress. Hydraulics Pneumatics We need to go one step further, however, and divide the number of teeth on the spur gear (100) by the number of teeth on the pinion (20). Enter your car's internal drive ratio to see the final drive ratio (FDR), and see the percentage change in gearing you'll get from a new pinion and spur. Rear tire diameter (Optional, for rollout). Finishing and Plating You can find out tangential force if you divide the power to circumferential speed. If you enter the pitch diameter value as the unit of in., you will have the velocity as in/s. Economics Engineering = the gear engagement velocity(1,96m/s) x the tangential force (F3= 20N) = 1,96.20 =3,92W Allowing 1% loss on a typical spur gear engagement the power loss at this engagement = 0,39W. Applications and Design Tangential force acting on the gear tooth is found from the torque on the pinion, using F t = T 1 1 2 d p, 1 The permissible root bending stress is denoted by b p for the material.
