Q.15
Power is transferred between an electric motor and a pump with a chain drive. Calculate the required number of driven sprocket teeth and chain length if the motor and pump areinches apart, and the driven shaft must rotate atr/min. The driving sprocket is installed directly on the motor shaft and hasteeth. The plate on the motor indicates a nominal speed ofr/min. The chain has a pitch of 0.5 inches.

  • The driven sprocket has 54 teeth and the chain length is 57.7 inches
  • The driven sprocket has 17 teeth and the chain length is 57.7 inches
  • The driven sprocket has 54 teeth and the chain length is 51.3 inches
