- Consider the velocity triangle illustrated for a particular rotor.Draw a kinematic diagram of an open differential in roller bearingsWhat type, size, and a number of classical V-belts is recommended for this system. The motor is rated at 3 Hp, VFD controlled and runs at 1750 rpm under load. The output speed required is 1075 rpm. The application is a saw that cuts wood and the environment is dusty. Target center distance is 18 inches, but 16 to 20 inches is acceptable. Due to clearance constraints, the driven pulley may not be larger than 6 ½ in. The motor will slide to adjust tension.8 hours service per day.
- Select a suitable Vbelt drive for a flour mill transmitting power from a motor of 10 kW rotating at 1,440 rpm using suitable charts. The mill rotates at 400 rpm for a service of 22hrs per day and is to be arranged in minimum space with center distance of 0.5m. Assume that the pitch diameter of small pulley is 100mm.Describe the differences between floating and fixed rotors.Explain the working principle of torque tube drive with neat sketch.
- Explain about controlling torque using Spring control method. Diagrams – draw neatly , scan and attachedSee the answer A flat belt drive system is to be designed for an application in which the input shaft speed (driving pulley) is 1725 rpm, the driven shaft speed is to be approximately 960 rpm, and the power to be transmitted has been estimated as 3.0 horsepower. The driven machine has been evaluated and found to have characteristics of moderate shock loading during operation. The desired center distance between driving and driven pulleys is approximately 18 inches.Your centrifuge rotor diameter is 40cm. Calculate the rcf for 1500 rpm, 5753 rpm, 654 rpm.
