1Most enclosed drives are used to AIncrease speed and output

1-Most enclosed drives are used to:

(A)Increase speed and output torque. (B)Increase speed and reduce output torque.

(C)Reduce speed and output torque. (D)Reduce speed and increase output torque.

2-The efficiency of these gears tends to be lower than other gear types

(A)Helical (B)Spur (C)Spiral Bevel (D)Cylindrical Worm

3-Spur gears produce this type of force when transmitting horse power:

(A)Axial (B)Radial (C)Both axial and radial (D)Neither

4-The gear design that cancels out any axial forces during power transmission is:

(A)Single helical (B)Internal spur gear (C)Double herringbone (D)Worm gear

1-What are four advantages of traction drives?

2-List seven different types of gearing (speed reduction)?
