For an involute profile gears:
- During the action the pressure angle remains constant.
- No fluctuating load on support as well as no fluctuating torque output.
- With the change in the center distance, the law of gearing is still satisfied, however, the operation becomes noisy.
- The center distance for a pair of mating gears can be varied within limits without altering the velocity ratio.
