TUTORIAL 3c - CHAIN DRIVE

The three basic components of a chain drive are?

• Chain, roller and pin

• Chain, master link and roller

• Chain, driver sprocket and driven sprocket

• Pins, rollers and bushing

What is is the purpose of the pitch in roller chains?

• To calculate the chain speed

• To define the distance between the pins connecting adjacent links

• To adjust the chain tension

• To determine the chain length

What is the basic geometry shown in a chain drive?

• Sprocket teeth, chain pitch, chain length, chain speed, chain tension

• Sprocket size, chain pitch, chain length, chain speed, chain tension

• Number of teeth, pitch diameter, center distance, chain length, angle of contact

• Number of links, chain pitch, sprocket diameter, chain tension, chain speed

The efficiency of a chain drive as compared toa belt drive is....

• low

• high

• both (A) and (B)

• none

5. The noise in a chain drive as compared to a belt drive is...

• less

• more

• equal

• none

Chain drives are used in.....

• bicycle

• motorcycle

• automobile

• All of the above

In roller chain, the rolling friction reduces....

• wear

• frictional power loss

• improves the efficiency of the chain drive

• all of the above

What is the purpose of a tensioning device in chain drives?

• To adjust the chain length

• To increase the chain speed

• To adjust for slack in the chain

• To lubricate the chain

Chain drives require little or no maintenance and creates no noise.

• True

• False

Chain drives suffer from wear problems.

• Yes, chain might leave the sprocket

• No, there is no wear problem

• Wear is insignificant in chain drives

• None of the listed
