Fig. 14.17 A line shaft is to transmit 30 kW at 160 r.p.m. It is driven by a motor placed directly under it by means of a belt running on alm diameter pulley keyed to the end of the shaft. The tension in the tight side of the belt is 2.5 times that in the slack side and the centre of the pulley over-hangs 150 mm beyond the centre line of the end bearing. Determine the diameter of the shaft,...
A transmission shaft is supported on two bearings which are 1m apart. Power is supplied to the shaft by means of a flexible coupling, which is located to the left of left hand bearing. Power is transmitted from the shaft by means of a belt pulley, 250 mm
A transmission shaft is supported on two bearings which are 1m apart. Power is supplied to the shaft by means of a flexible coupling, which is located to the left of left hand bearing. Power is transmitted from the shaft by means of a belt pulley, 250 mm diameter, which is located at a distance of 300 mm from the left hand bearing. The mass of the pulley is 20 kg and the ratio of belt tension on tight and slack sides is 2:1. The...

A-V belt is to transmit 20 kW from a 250 mm pitch diameter sheave to a 900 mm diameter pulley. The center distance between the two shafts is 1000 mm. The groove angle is 40' and the coefficient of friction for the belt and sheave is 0.2 and the coefficient of friction between the belt and flat pulley is 0.2. The cross-section of the belt is 40 mm wide at the top, 20 mm wide at the bottom and 25...

Problem 4- The Fig. below shows a shaft carrying a pulley A and a gear B and supported in two bearings C and D. The shaft transmits 30 kW at 200 r.p.m. The tangential force Ft on the gear B acts vertically upwards as shown. The pulley delivers the power through a belt to another pulley of equal diameter vertically below the pulley A. The ratio of tensions T1/T2 is equal to 2.5. The gear and...

A pair of bevel gears is required to transmit 11 kW at 500 r.p.m. from the motor shaft to another shaft, the speed reduction being 3 : 1. The shafts are inclined at 60º. The pinion is to have 24 teeth with a pressure angle of 20º and is to be made of cast steel having a static stress of 80 MPa. The gear is to be made of cast iron with a static stress of 55 MPa. The tooth...

Determine the number of V-belts required to transmit a power of 60 kW at 750 rpm from an electric motor to a compressor shaft at 300 rpm. The larger pulley diameter is 1500 mm. The centre distance is 1650 mm, and overload factor is to be taken as 1.5. A belt with cross- sectional area of 350 mm², density of 1000 kg/m and having an allowable tensile strength of 2 MPa is available for use. The coefficient of friction between...

3. Power transmission is an important engineering application and relies on the integrity of the shaft designs. Assume a solid, circular steel shaft with a uniform diameter d 50 mm and a total length I3 m. At its midpoint, a belt passes over a pulley and delivers 50 kW power to the shaft. This power is used to drive two machines at either end of the shaft. Machine 1 consumes P1 20 kW and machine 2 uses P230 KW. The...
