A belt drive is used to transmit power from an electric motor to a compressor for a refrigerated truck. The compressor must still operate when the truck is parked and the engine is not running. The 20-hp electric motor is rated at 1400 rpm, and the motor sheave diameter is 4.5 in. The compressor sheave has 6.75 in. diameter. Determine the appropriate industrial belt size, the operating speed of the compressor, and the belt speed.

Step 1
Determine the operating speed of the compressor: We know that the motor is rated at 1400 rpm, but we need to find out the operating speed of the compressor. To do this, we can use the formula: Motor speed x Motor sheave diameter = Compressor speed x Compressor Show more…

A belt drive is desired to couple the motor with a mixer for processing corn syrup. The 10-hp electric motor is rated at 3550 rpm, and the mixer must operate as close to 900 rpm as possible. Select an appropriate belt size, commercially available sheaves, and a belt for this application. Also, calculate the actual belt speed and the center distance. Assume: - An industrial V-Belt - Single belt - Compact Design - Smallest drive sheave so that driven speed is 900 rpm +/- 5% - Aim for the shaft spacing that is an even whole number 1.) The nomenclature of the properly selected V-Belt is _____ V. 2.) The magnitude of the "ideal" VR for the belt drive is _____. 3.) Consider the speed range (bandwidth) that the mixer shall be allowed to operate. The magnitude of the larger speed is _____ rpm. 4.) Consider the speed range (bandwidth) that the mixer shall be allowed to operate. The magnitude of the smaller speed is _____ rpm.

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.

The 1800 -rpm, 150 -hp motor of a compressor is burned out and is to be replaced by either a standard motor that has a full-load efficiency of 93.0 percent and costs $\$ 9031$ or a high-efficiency motor that has an efficiency of 96.2 percent and costs $\$ 10,942 .$ The compressor operates 4368 h/yr at full load, and its operation at part load is negligible. If the cost of electricity is $\$ 0.125 / \mathrm{kWh}$, determine the amount of energy and money this facility will save by purchasing the high-efficiency motor instead of the standard motor. Also, determine if the savings from the high-efficiency motor justify the price differential if the expected life of the motor is 10 years. Ignore any possible rebates from the local power company.
