WOW Mechanical Drives

Mechanical drives are used to

• transmit motion and power.

• transmit motion only.

• transmit power only.

• run the machine only.

The advantage of using gear drive is

• they are easy to assemble.

• they are slipping positive drive.

• they are excellent for motion control.

• they are easy to manufacture.

The gear which is turned by a motor is known as the

• worm gear.

• bevel gear.

• driven gear.

• driver gear.
