Belt calculation method, how to calculate the length of the belt

Generally, belts are based on thickness and material as the most specifications, so the general calculation is calculated by square, that is, the length is multiplied by the width. Timing belts and toothed belts are calculated by the meter, which is how much per meter.

Like you said, the belt belongs to the industrial belt, which plays a transmission role. Among them, the synchronous belt is to distinguish different tooth shapes, tooth pitches, number of teeth, etc., and there are many different models, which are roughly divided into trapezoidal and arc-shaped synchronous belts; The conveyor belt is a flat belt with a dragon belt, a piece base belt, etc.

Total square = width * "cloth layer + (upper rubber surface + lower rubber surface)" * number of meters.

How to calculate the length of a roll of belt and what is the formula?

<> pro

I'm glad to answer for you: there are many ways, let's say two! Method 1:

The calculation method of weight lift-off is to weigh the total weight of the belt and divide it by the theoretical weight of each meter of the belt. For example, EP300 B1000*5 (, the total weight is 1 ton, and the theory of each meter is 1000, that is, 1000, and the length of this belt is 66 meters (considering the removal of skin and error loss). Method 2:

That is, the trapezoidal surface noise dissipation method, that is, (upper bottom + lower bottom) * height 2, that is, the belt (inner roll circumference + outer ring circumference) * layer 2 is approximately equal to the total length of the belt. For example, EP300 B1000*5 (, the inner diameter of a roll is 330mm, the outer diameter is 1200mm, a total of 44 layers. i.e. (, the length of this belt is 105 meters.

The length of the belt is generally between 110cm and 130cm for men and 90-120cm for women.

In general, different waist circumferences should choose different belt lengths, that is to say, the selection of belt size should be based on the size of the waist to choose the appropriate size.

According to the comparison of men's waist size and belt length positive crack beat, the comparison is as follows: 105cm belt for ruler waist, 110cm belt for ruler waist, 115cm belt for ruler waist, 120cm belt for ruler waist, 125cm belt for ruler waist, 130cm belt for ruler waist.

Formula: Lift auspicious roll radius squared - axis radius squared) belt thickness.

<> Belt length calculation formula:

lb = df + dm) ) 2 lfm)lb = belt length.

df = large pulley diameter.

dm = small pulley diameter.

lfm = distance between the center of the large pulley and the center of the small pulley.

Belt length calculator.

Belt speed calculation formula:

v = dm nm / 12

v = belt speed (ft min).

nm = motor speed (rpm).

The method of calculating the brightness of the long letter of the belt will vary slightly depending on the shape and use, but the basic calculation method is determined according to the measurement of the circumference of the belt under the force state. The calculation of the belt length is very important for the operation of many machines or drives, of course, it is necessary to measure and calculate the length correctly.

The length of the belt can usually be calculated according to the type of belt. Before calculating the length of the belt, it is necessary to understand the type of belt structure, because the calculation method may be different for different types of belts. For example, the V-belt is V-shaped.

The effective diameter calculation method is usually used to calculate the perimeter of this belt - by measuring the diameter of the V-belt, the effective radius of the V-belt is calculated, and then the effective radius is multiplied by 2 plus the diameter of the head tail end to obtain the length of the entire belt.

In addition, other belt shapes, such as chain belts, require different calculation methods to calculate the belt length. This requires measuring the circumference of the belt first, and then calculating the length of the belt with a simple formula. Regardless of the calculation method used, it is important to ensure that the standard for calculating the length of the belt is highly accurate.

To put it simply, the method of calculating the length of the belt needs to be considered in many aspects, some belts may need to be calculated using formulas, while others need to be measured with professional equipment. When carrying out related operations, it is recommended to use professional tools and methods to ensure the accuracy of the belt length, so as to ensure the operational stability of the machine. Of course, with the further advancement of science and technology, it is believed that there will be more efficient and accurate methods in the future.

The calculation method of the length of the belt, the length of the belt has a formula to calculate. The details are as follows:

<> Belt length calculation formula:

lb = df + dm) ) 2 lfm) where, lb = belt length, df = large pulley diameter, dm = small pulley diameter, lfm = distance between the center of the large pulley and the center of the small pulley.

Flame-off treatment in waterWhen the car is turned off in the water, it must not be started again, otherwise it will cause irreparable damage to the car engine. In the case of ensuring the safety of personnel, the vehicle should be immediately pushed out of the deep water area to ensure that the engine intake does not inhale water again if the car intake is closed, and park in a safe place. Remove the distributor cover, dry the cover with a paper towel, and reinstall the slag store.

If water enters the inlet duct, the air filter must be replaced, and the spark plug must be removed to drain the water from the combustion chamber.

Generally, according to the speed of the driving wheel * the diameter of the driving wheel = from the speed of the stool resistant wheel * the diameter of the driven wheel, the relationship between each other is calculated, therefore, when the diameter of the driving wheel in the problem is r, 3200 * r = 1000 * 230 so r=, considering the belt slippage and other factors, the diameter of the driving wheel should be increased a little more, and the increase is related to the type of belt, load (transmission power), you can consider choosing a diameter of 75mm; However, the small diameter belt rate is easy to slip, causing the transmission power to decrease, you can consider the appropriate jujube Peichun when increasing its diameter, that is, increasing the diameter of the driving wheel, while increasing the diameter of the driven wheel, after the change of the calculation formula is still calculated as above.

The formula for calculating the belt frequency is f=1 t.

Because the formula for calculating the frequency is: f=1 t. Frequency, is the number of times the periodic change is completed in time, is the quantity that describes the frequency of periodic motion, commonly used symbol f or deputy, the unit is one second and a minute, and the symbol is s-1, so the formula for calculating the frequency of the belt is f=1 t.

The calculation formula is an expression method that people find some connections between things in the natural comic boundary and express them in a certain way.
