A compressor is to run at 250 rpm and requires 75 kW. The drive is provided by V-belts from an electric motor running at 750 rpm. The pitch diameter of the pulley on the compressor is 750 mm and the centre distance between the motor shaft and compressor shaft is 1500 mm. Determine the number of V-belts required to transmit this power if each belt has a cross-sectional area of 375 mm2, density of 1000 kg/m3 and an allowable stress of 2.5 MPa. The groove angle of the pulley is 35° and the coefficient of friction between the belt and pulley is 0.25.

Expert Solution

Solution:- The given problem has been solved using the standard formulas and principles used in the design of V- belts. Power transmitted by each belt is calculated to find the number of V-belts required to transmit the total power.

A journal and bearing are to be designed for a shaft that turns at 250 rpm. Suppose ISO VG100 (SAE Engine 30) is to be used as lubricant and the bearing length is to be equal to 1.2 times the diameter. If the no-load power loss is not to exceed 2.5 x 10-4 horsepower and the diametral clearance is 0.0045 times the diameter, estimate the maximum diameter that can be used for the journal, and the allowable temperature limit.

15. A four stroke oil engine developing 75 kW at 300 r.p.m is to have the total fluctuation of speed limited to 5%. Two identical flywheels are to be designed. The workdone during the power stroke is found to be 1.3 times the average workdone during the whole cycle. The turning moment diagram can be approximated as a triangle during the power stroke. Assume that the hoop stress in the flywheel and the bending stress in the arms should not...

A motor apply power 10-hp split-phase motor speed at 1700 rpm is used to drive a rotary pump, which operates 24 hours per day. An engineer has specified a 7-in small sheave, an 10-in large sheave, and three C112 belts. The service factor of 1.2 was augmented by 0.1 because of the continuous-duty requirement. Analyze the drive and estimate the belt life in passes and hours.

To transmit 75 kW at 25 rev/s using 48 mm diameter shafting. The flanges are to be made of cast iron and keyed to the shafts, and power is transmitted from one flange to the other by a circle of fitted bolts (four are shown in the above figure but more or less bolts can be used). The adopted bolts must comply to the following technical specification: Property Class Designation: 4.6 Nominal size range: M5 – M100 (Sizes M5 to...
