A Drive Pulley or Head Pulley is used for the purpose of driving a conveyor belt. They are normally mounted in external type bearings and driven by a motor and reducer. Conveyor head pulleys can be flat faced or crowned and many have lagging to reduce belt slippage. Conveyor drum pulleys, wing pulleys and spiral pulleys are the most common ...

Now, we already know the size of the pulley, either from the manufacturer's data or we can go out into the building and actually measure this. Remember Pulley 1 is always going to be the largest pulley you have, and you'll see this as we go through the calculations shortly. We also have Pulley 2 and we know the diameter of this pulley as well.

Determine the face length of the conveyor pulley: The face length of a conveyor pulley is a derivative of the conveyor belt width. In bulk-handling applications, an adequate pulley face length is one that is 2 or 3 inches greater overall or 1 to 1.5 inches greater on each end than the overall width of the conveyor belt.
Pulley Crowns. Crowning one or several pulleys in a belt system is the most common way of tracking a belt. For flat power transmission belts and narrow conveyor belts (up _ to _ 8 _ in.), a radius crown is used. For wider conveyor belts, a trapezoidal crown is typically applied. Note: Never utilize an apex crown!
Say you want to know what size pulley to use on that old planer to get 3450 RPM, you know the motor RPM is 1725 and the pulley on the motor is 6". Simply enter the values and click "Calculate". To use this calculator you must enter at least 3 values in the spaces below. Enter the RPM of the drive motor. Enter the drive pulley size.
The pulley diameter is mainly determined by the conveyor belt class, but the required shaft diameter also influences the diameter. A golden rule for the pulleys diameter is that it should be at least three times the diameter of the shaft. 2.1 Pulley Types. There are two main types of pulleys i.e. the Turbine pulley and the TBottom Pulley.
Approximate Belt Conveyor Oven Size Equipment width will be approximately 3 feet wider than belt width to accommodate belt bed clearance, insulation, duct work, control enclosure, and belt drive. The heat zone length will only be a portion of the oven's overall length. The length of load and

All conveyors require an additional belt tension in order to allow the pulley to drive forward an effective tension without slipping. In a case of a simple horizontal conveyor T1 is the sum of the effective tension Te and the slack side, the tension T2. T 1 = T e + T 2 = For the inclined conveyor…
That mathematical equation is as follows: 4" divided by .611 = 6.55". For the same pump, driven by a gas engine, 1070 (pump RPM) divided by 3400 (engine RPM) = .315. If the drive pulley on the engine is 4 inches in diameter, we need to calculate 4/.315 = 12.70. This means that the pump pulley must be 12.70 inches, in diameter, to run the ...

The speed at which the conveyor belt moves depends on the size of the rollers and their revolutions per minute. Measure the diameter of the rollers around which the conveyor belt is wrapped. Multiply the diameter of the roller by pi, 3.14159. This calculation yields the circumference of the rollers.
Enter any 3 known values to calculate the 4th 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 tail pulley is located at the tail end of the conveyor and it turns freely. Now a "belt" can be put around the pulleys. The Drive Pulley turns and moves the belt around (and around, and around). But it is dangerous to have the belt hang down under the conveyor bed. So small rollers are put into the Conveyor Bed to hold up the belt.
The width of the conveyor belt. The width is the easiest to determine because you can verify this information by measuring the old conveyor belt. Check if the belt edges are worn, which could significantly alter the width of the original belt. Also check that the belt width matches the width of the pulley.
It is typical of conveyor system to have a tensioner on the low side of the belt, tight control of the wrap angle and at times the use of several drive pulleys one after the other. Using the cosine rule we can arrive at the total combined force on the shaft. The vertial component will be …
Measuring a v-belt pulley is simple, however, when it comes to properly identify a v-belt pulley there is a multitude of different styles and options. We standardly stock over 8,000 SKUs of different v-belt pulleys alone! How To Measure A V-Belt Pulley Please Note: For the below illustrations we use a standard single-groove v-belt pulley. Step 1:
To be more precise, you can wrap a string tightly around the flat of the pulley where your belt rides. Mark the string where they overlap, then measure its length. Divide that number by 3.14. In this flat idler, the string measured 10 1/4''. Typing 10.25÷3.14 into a calculator gets you 3.26, so the flat diameter is …
Whether you need a pulley for a clothesline or for your sailboat, determining the necessary pulley size requires just a few simple calculations. The two basic pulley systems are "rope and pulley" and "belt and pulley" which are made of two different sized pulleys: the driver pulley, the smaller, and the driven pulley, the larger.
Example 12.4. A fan is belt driven by an electric motor running at 1500 rpm. The pulley diameters for the fan and motor are 500 mm and 355 mm, respectively. A flat belt has been selected with a width of 100 mm, thickness 3.5 mm, coefficient of friction 0.8, density 1100 kg/m 3 and permissible stress 11 MN/m 2.The centre distance is 1500 mm. Determine the power capacity of the belt.
J MOTOR = W ROLLER = W BELT = 0 for our initial calculation. Therefore, T ACCEL = 199 oz-in. C. T FRICTION. The friction torque (T FRICTION) can be estimated through measurements as described in the "Test Motor Method" on page 4 of the PDF or at the end of this blog post.For our example, we will assume the measured T FRICTION = 100 oz-in.. D. T BREAKAWAY ...
