Conveyor Tension and Take-Up Systems - Iptron Tech

Conveyor and T2, the Take-Up Tension, of a Conveyor Belt. This ratio is of the order of 10 for a single drive pulley. This is defined by the formula: T1/T2 = eµα Where: T1 = Incoming Tension T2 = Take-Up Tension e = 2.718 (natural logarithm) µ = Coefficient of Friction on the Pulley α = Wrap Angle of the Belt on the Pulley in Radians

Once T2 has been determined, maximum belt tension may be calculated using this equation: T1 = Te + T2 This value is required to select a belt. As shown in this video, T1 will occur in the immediate vicinity of the drive pulley in the case of an inclined conveyor with a conveyor drive in the head pulley position.

or justify the allowance of a tension take-up reserve. Generally, depending on the load, an elongation at fitting in the range of approx. 0.1 – 1% is adequate; a tension take-up range x of 1% of the belt length is therefore sufficient. When assessing shaft loads please take into account the differing belt pulls in stationary and operational modes.

Conveyor Overview - SAIMH

A troughed belt conveyor comprises an endless, rubberized flat belt (a) suspended between pulleys at either end and supported along its length by a number of rotating idler rollers (b). The belt is driven via one of the pulleys (usually the head pulley (c)) and the tension in the belt is maintained by using a sliding pulley (d) which is tied to a gravity take-up unit (e).

conveyor and processing belts - ttechnik

In weight-loaded take-up systems, the tension weight must generate the mini-mum belt pull F 2 to achieve perfect grip of the belt on the drive drum (spring, pneumatic and hydraulic take-up systems work on a similar principle). The tension weight must be able to move freely. The take-up system must be installed behind the drive section.

The screw take-up is normally used on short conveyors up to a length of 50 meters. Over 50 meter an automatic take-up system should be used to ensure constant pre-tension. The length of the take-up depends on the both the center distance of the conveyor and the type of belt. The screw take-up on shorter belts is normally located at the tail end.
