What is the relation between the tight side and slack side for a flat belt?

Slack side tension is created on the section of belt approaching the driveN pulley. These tensions are illustrated as follows: Tight side tension plus slack side tension is equal to to total tension (TT). This can be stated as T1 + T2 = TT.

Why the tension differs from slack to tight side of the belt conveyor?

what causes slack side and tight side is the difference in tension induced due to friction between the pulley and belt. If pulleys are rotating in clockwise direction, relative motion is anticlockwise for belt. hence friction will be in clockwise direction where ever is considered on belt.

Why tight side of the belt should be at bottom side of the pulley?

When we keep the tight side as the lower side then more area of belt makes contact with the pulley which is less likely to slip because of friction. So it is mostly arranged in such a way that the lower side of the belt (especially in case of flat belts) is the tight side.

What is tight side and slack side?

When rotating around the pulleys, the belt is exposed to different loads. The section of the belt in which the belt is strongly pulled towards the driving pulley and is thus exposed to a large tensile load is referred to as the tight side. … This belt section is called slack side.

How do you calculate maximum belt tension?

To conclude, the total belt tension as calculated above is usually expressed as a unit tension for reference against various information tables. This is done by dividing the total calculated tension by the belt width. Therefore Unit Tension = Belt tension (N) / Belt width (mm) giving units of N/mm width.

What is tension ratio in belt drive?

The tension in the “Tight Side” can be called “T1”. … This is the effective tension ratio between the tight and loose sides of the belt. For a belt drive between pulleys of different diameters, the angle of contact of the smaller pulley should be used.

Which side of the belt is to be kept as tight side?

Generally, the lower side is kept “Tight side” and upper side is kept as “Slack side” with the belt drives having small driving pulley and big driven pulley. Why ? Answer: Power transmission in belt drive depends on angle of lap and frictional grip between belt and pulley.

When the two pulleys are stationary the tension in the belt is called tension?

Initial tension (To):

When a belt is first fitted to a pair of pulleys, an initial tension To is given to the belt when the system is stationary. When transmitting power, the tension on the tight side increases to T1 and that on the slack side decreases to T2.
