• A shipping company is in need of a conveyor belt. At any given time, it is expected that the conveyor is loaded with 10 boxes weighing 50 lbs each. The conveyor needs to be at 17 degrees angle with the horizontal. The motion source runs at 1800 RPM. Assuming 100% efficiency and the conveyor pulley diameter is 10 inches. o Calculate the required horsepower. o Suggest a speed reduction solution using spur gears o Suggest a speed reduction solution...
Design a complete mechanical power transmission for a conveyor system. There are 28 – 40 lbs boxes on the conveyor at 1 time, the construction is rubber on wood at a 0o angle from the horizontal, the diameter of the conveyor pulley is 6”, the velocity of the belt is 270-280 ft/min. Assume heavy shocks and 10+ hours per day operation.
find v belt drive
design power
select belt type
determine shive size (belt speed 4000 ft/min)
find shive size from power rating figure
find rated power
find estimated centre distance
find belt length (by selecting standard belt length)
calculate actual centre distance
find contact angle for small shieve
determine correct factors
calculate correct power per belt
no. of belt needed
V-Belt Designing Sample Problem . Given: A 4 cylinder diesel engine runs at 80 hp, 1800 rpm, to drive a...
Figure 1 shows the layout of countershaft used to transmit power to a blower through a pulley drive (4-5). Pulley (driving sheave) 4 has a diameter of 125-mm and pulley (driven sheave) 5 has a diameter of 75 mm. Pulley 5 is mounted vertically below pulley 4 (as shown in the figure). Belt tension on the loose side is 20% of the tension on the tight side. A power of 7.5 kW is transmitted via the gear set (2-3) from...
