An electric motor drives a flat-belt pulley at a shaft speed of 1750 rpm. The 600 mm wide Polyamide F-2 belt driven at a speed of no more than 17.5 m/s is used to drive a second shaft over a distance of 5 m at a maximum shaft speed of as close to 900 rpm as possible. The system requires a service factor of 1.2. Using the abovementioned information to calculate the following and submit the answers online. a. the configuration required to satisfy the speed requirements using commercial pulleys b. the maximum nominal power rating of the motor when driving the belt under light shock conditions c. the pre-tension required to prevent slippage d. the required belt length and e. the dip in the belt.

Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.

second shaft over a distance of 5 m at a maximum shaft
speed of as close to 900 rpm as possible. The system
requires a service factor of 1.2.
Using the abovementioned information to calculate the
following and submit the answers online.
a. the configuration required to satisfy the speed
requirements using commercial pulleys
b. the maximum nominal power rating of the motor when
driving the belt under light shock conditions
c. the pre-tension required to prevent slippage
d. the required belt length and
e. the dip in the belt.

Q1) A V-belt drive consists of three V-belts in parallel on grooved pulleys of the same size. The angle of groove is 30° and the coefficient of friction 0.12. The cross-sectional area of each belt is 800 mm² and the permissible safe stress in the material is 3 MPa. Calculate the power that can be transmitted between two pulleys 400 mm in diameter rotating at 960 rpm.
Below question is from machine design. Please solve asap. You have to select bearings which are used to support a shaft, bearings are mounted at each end of shaft and 1.20 metre apart. A 600 mm diameter pulley is mounted at a distance of 300 mm to the right of left hand bearing and this drives a pulley directly below it with the help of belt having maximum tension of 2.25 kN. Another pulley 400 mm diameter is placed 200 mm to the left of right hand bearing and is driven with the help of electric motor and belt, which is placed horizontally to the right. The angle of contact for both pulleys is 180º and .Allowing working stress of shaft depends on the material you have selected for the shaft. Select the type of bearing mounted on both ends of shaft (either ball or roller bearing type and also elaborate the scenario for the selection of bearing).The Reliability Factor for Bearing may vary from 92% till 96%
