The capstan equation or belt friction equation, also known as Eytelwein''s formula, relates the holdforce to the loadforce if a flexible line is wound around a cylinder (a bollard, a winch or a capstan. Because of the interaction of frictional forces and tension, the tension on a line wrapped around a capstan may be different on either side of the capstan.

Force – Deflection Method of belt tensioning: Measure the belt span length and calculate the desired deflection distance (1/64" per inch of span length) Using a spring scale, press down on the belt in the approximate center of the span, and deflect the belt to the desired level.
The image above shows the formula we''re going to use to calculate this. It looks quite long but it''s not as complex as it might first seem. I''ve also colour coded the numbers, as many as possible, just to make it a little bit easier. And I''ve also split the calculations into metric and imperial. So whichever units of measurement you''re using, you can follow these through.

The minimum belt tensions for transmitting. the pulley peripheral forces are calculated as follows, where . Fu = minimum peripheral force. C = coefficient C. f = artificial friction coefficient. L = conveyor length (m) g = acceleration (m/s²) q Ro mass of revolving idler parts of top strand (kg/m), q Ru mass of revolving idler parts of bottom strand (kg/m), q B mass of the belt on top strand ...
BROWNING® Belt Tension Checker See Form 5453 for more detail. How to increase Belt Life Keep sheaves and belts clean. Abrasive dust, rust, oil and acids reduce service life. Give drives elbow room. Never let belts run against belt guards or other obstructions. Use large diameter sheaves and fewer belts. You save money and increase drive life. Never force belts. Move motor on adjustable base ...
· A Belt Tension Meter is a handheld device that has two elements: an optical sensor and a meter. It is designed to detect the vibration of a belt using an infrared invisible beam and a light that allows you to aim it. The first step is to load the belt''s span and mass data into the meter. Mass data can be obtained from any belt manufacturer and varies between them. Aim the sensor as close to ...
Next, the total tension To = Te + Ts To is the total operating tension, or commonly called Allowable Working Tension, and is expressed in PIW (pounds per inch of width). To is sometimes referred to as TL. Additional tension must be added to the Effective Belt Tension to .
If the centre distance (C) is known, belt length or pitch length can be determined as follows: So if you know the distance between the center points of the pulleys, and their diameters, you can calculate the length of belt you need using this formula.
VBelt Tension Ranges for Manual Tensioners Always use a belt tension gauge that indicates static tension, such as the Gates Krikit® Tension Gauge, to determine proper tension from the Installation Chart. Tension ranges below are for drives requiring single belts. If multiple belts are needed for a drive, divide tension by number of belts to give per belt tension to be measured. Position belt ...
To properly tension a synchronous belt, place belt on pulleys and adjust takeup until the belt teeth mesh securely with the pulley grooves. Measure belt span "T". Then tighten belt so that it deflects 1/64inch for every inch of belt span when a force as specified in the table below is applied to the top of the belt. For belts wider than two inches, a metal or wooden strip 3/4 to 1inch wide ...

Belt pretension (initial tension), T i, is the tension set by an adjustable idler pulley. Pretension prevents belt slackside sagging and ensures proper tooth meshing. In most cases, timing belts ...
· The tension required to move the materials on the belt horizontally, or TL, is the next step in calculating conveyor belt tension. You''ll need to know the material weight in pounds, or MW, and multiply it by the belt length and the typical friction factor needed to move a load horizontally, or F2. F2 is normally, and the formula for calculating TL is TL = MW x L x F2 or MW x L x
Effective Tension. Pull needed to move belt and load horizontally: E= F x (P+M) Tight Side Tension. Total tension to move belt and load horizontally: E 2 = E+E 1. Slack Side Tension. Additional tension required to prevent slippage on drive pulley: E 1 =E x K. Operating Tension. Determines the working strength of the belt to handle the job on per inch of width basis: T= E 2 /W. The Coefficient ...
Additional tension must be added to the effective Belt Tension (Te) to prevent slippage on the drive pulley. This is called Ts, or commonly referred to as T2. * Ts = D X Te * D = Drive factor (Table B in Engineering Handbook: Drive Factor) TC = F 1 x L x CW: F 1 = .035″ [Normal friction factor for average conditions (over 20°F) to move empty belt.]L = Belt length (ft.)CW = Weight of ...
· Belt tension can also be measured, or estimated, by causing the belt to deflect by a given amount (typically 1/64 inch per inch of belt span, or mm per 25 mm of belt span) with a specified force. Often referred to as the forcedeflection method, the minimum and maximum forces necessary to produce the specified deflection for a given tension are calculated via formulas. Note that this ...
Belt Tension Calculator First, the Effective Belt Tension (TE) must be calculated. TE is the sum of the tension required to move the empty belt (TC), the tension required to move the load horizontally (TL), and the tension required to lift the load (TH). Example 1. TE = TC + TL + TH TC = F1 x L x CW F1 = .035" [Normal friction factor for average conditions (over 20°F) to move empty belt.] L ...
Tension Formula Questions: 1) There is a 5 kg mass hanging from a rope. What is the tension in the rope if the acceleration of the mass is zero? Answer: The mass, m = 5 kg; the acceleration, a = 0; and g is defined. T = mg + ma. T= (5 kg) ( m/s 2) + (5 kg)(0) T = 49 kgm /s 2 = 49 N. 2) Now assume an acceleration of + 5 m/s 2 upwards. T = mg ...
