A hammer mill is driven by a High Torque (HT) AC motor. The system is used for 8 hours /day. Input speed is 870 RPM and input power is 25 HP. Nominal output speed is 310 RPM. Design a V-belt drive and specify: (a) (b) (c) (d) (e) the belt size, the sheave sizes, the number of belts,               theactualoutputspeed, the center distance. Show all your calculations.

Don't give handwritten otherwise i will downvote

• HOME WORK Design the elliptical cross-section of a belt pulley arm near the hub for the following specifications: The mean pulley diameter is (300 mm) and the (number of pulley arms are 4). The elliptical section has major axis twice the minor axis length. The tight and slack sides tension in the belt are (600 N and 200 N) respectively. Assume half number of arms transmit torque at any time and the load factor of 1.75 to account for dynamic effects on the pulley while transmitting torque. The permissible tensile stress for cast iron pulley material is 15 MPa. The pulley hub diameter is 60 mm. [Ans. a=40 mm, b₁= 20 mm]

Hello, could you please help. i need to work out the holding torque, thanks

If the peak power of your electric motor occurs at a torque (Tm) of 0.001 Nm and you have a load (FL) of 1.2 Ibf to pull using a motor, gear box, and winch (rw-0.125 inches). What gear ratio would result in the load moving as fast as possible at equilibrium? Tm Motor Gear Tgb W Воx gb F.

TO THE NEXT PROBLEM Design a complete belt drive system for an AC motor (NT) running a fan 12 hrs/day, with an input power 10 hp and input speed of 1000 RPM. The desired output RPM and center distances are 500 RPM and 36 inch, respectively
