1. The angle of the input shaft to the output shaft is 90 degrees.
2. The speed remains constant.
3. The torque is held constant.
4. If the input gear were larger than the output gear the speed would increase and the torque would decrease.
5. The gear ratio is 1:1.
6. The flow of power is reversible in this mechanism.
7. Bevel gears are used in some cars differential and most hand drills.
Life is like a ten speed bicycle. Most of us have gears we never use. ~ Charles M. Schulz
