Straight Bevel Gears

Chapter Objectives

1. Choose a suitable value for the number of teeth on pinion 14 onwards and calculate the number of teeth on a gear from the given velocity ratio.

2. Calculate the pitch angles for pinion and gear.

3. Calculate the virtual number of teeth on a pinion with the help of pitch angle.

4. Find the cone distance in terms of module.

5. Determine the pitch line velocity of pinion in terms of module from given rpm of the pinion.

6. Find the tangential tooth load from given power to be transmitted.

7. Find the effective tooth load using service factor, velocity factor and tangential tooth load.

8. Find the design tooth load using FOS and effective tooth load.

9. Calculate the beam strength and wear strength from allowable static ...
