this article will discuss the methodology for the calculations of belt conveyor design parameters with one practical example of the calculations and selection criteria for a belt conveyor system. calculations include conveyor capacity, belt speed, conveyor height and length, mass of idlers and idler spacing, belt tension, load due to belt, inclination angle of the conveyor, coefficient of
lower numbers (such as 10, 16 or 24) denote a wheel with coarse grain. the coarser the grain, the larger the size of the material removed. coarse grains are used for rapid stock removal where finish is not important. higher numbers (such as 70, 100 and 180) are fine grit wheels.
the v-belt drive system operates a bit more efficiently and quietly than the flat belt, is able to carry slightly higher loads, and is less prone to slipping than the flat belt drives are. in comparing the two drive systems, flat belts drives are usually the lower cost drive option when compared to v-belt profile drives because the flat belt profile is an inherently simpler design.

number of belts cross section selection use the chart(figure 4) as a guide to the v-belt cross section to use for any combination of design horsepower and speed of faster shaft. when the intersection of the design horsepower and speed of faster shaft falls near a line between two areas on the chart, it is always desirable to investigate the possibilities in both areas. figure 4.
these flat idler pulleys and flat drive sheaves are designed for durabelt's flat urethane belts, but they also work well with any kind of flat belt. uses 6203 bearings -- 12 mm wide, 17 mm bore. our flat idler pulleys and flat drive sheaves are made from nylon reinforced with fiberglass and abec-1 ball bearings.

poly-v belts should be run on grooved pulleys for the best transmission of power, however flat pulleys can be used as idlers or even drive pulleys if required. due to the flexibility of the poly-v belt, flat drive pulleys can also be placed on the back side of the belt to make quite complicated serpentine drives all driven from the one drive shaft.
modern flat belts are made with reinforced, rubberized fabric that provides strength and high friction levels with the pulley (fig. 1). this eliminates the need for high tension, lowering shaft and bearing loads. flat belts can transmit up to 150 hp/in. at speeds exceeding 20,000 fpm. fig. 1. flat belts have thin cross-sections and wrap around pulleys easily
downloadable/printable timing belt identification and replacement (.pdf) the first step in identifying which timing belt that you have is to look for identifying numbers and/or letters marked on the timing belt. these numbers indicate a standard trade size and will help in identifying the specifics of the cog belt.

if you know any 3 values (pulley sizes or rpm) and need to calculate the 4th, enter the 3 known values and hit calculate to find the missing value. for example, if your small pulley is 80mm diameter, and spins at 1000 rpm, and you need to find the second pulley size to spin it at 400 rpm, enter pulley1 80, pulley 1 rpm 1000, pulley 2 rpm 400, and
the design of pulley systems and the selection of correct belt design and application are by no means simple. the number and variety of available belt types is a testament to this. v-belts, flat belts, wedge belts, synchronous belts and others all have their specific design and

timing belts are basically flat belts with a series of evenly spaced teeth on the inside circumference, thereby combining the advantages of the flat belt with the positive grip features of chains and gears. there is no slippage or creep as with plain flat belts. required belt tension is low, therefore producing very small bearing loads.

to figure out the number of gears you have, simply multiply the number of chainrings at the front by the number of cogs on your cassette at the back. however, the number of gears can be a
belt length = ((d l + d s) * π / 2) + (2 * l) + (d l - d s) 2 / (4 * l) where: d l is the diameter of the large pulley; d s is the diameter of the smaller pulley; and; l is the distance between the pulley axles. you can find the belt length calculated with this equation by clicking on the advanced mode button.
the last step in the belt selection process is selecting the stock number for your belt. when selecting the 3m stock number, use the configurable 3m stock number below to order the unique sized belt you need. additional part numbers can be found on 3m.com.
grinding wheel selection most of the basic rules which govern the selection of grinding wheels for other methods of precision grinding apply to peripheral surface grinding also. in this respect it is well to remember that the length of the arc of contact between the wheel and the work which results in peripheral surface grinding is greater than that in cylindrical (od) grinding and less than in internal (id)
