Conveyor Belt Tensioning Techniques

(Temperature affects belt length – if a belt goes through an oven or fryer, its length is extended). Manual or ‘screw’ take ups provide easy tensioning adjustment for short conveyors. For long conveyors, with appropriate drive arrangements, ‘spring’, ‘hydraulic’ or ‘pneumatic’ type tension adjustment are sometimes used.

Belt Tensioning Methods for Small ... - Dorner Conveyors

The mechanical advantage of this pinion gear is much less than a jack-screw. The pinion can be sized so that when it reaches the desired belt tension, it becomes difficult to turn. This minimizes the desire to over-tension the belt, lengthening conveyor belt and bearing life. Compact design. Only the end of the pinion needs to be accessed by ...

How to Choose a Mechanical Fastener for Your Conveyor Belt

02/07/2019  Each belt comes with a tension rating from the belt manufacturer, which is a measurement of the tension required to overcome the friction of the conveyor components. The conveyor components considered in this rating consist of the weight of the material being conveyed; the angle of the belt; and resistance from idlers, skirt board, and other system components. When it comes to belt ratings ...

Conveyor Belt Mechanical Splicing vs Vulcanizing Agg

‘Mechanical fasteners cannot be used with higher-tension belts’ (ie more than 800 PIW). Synthetic belts and improved fastener designs have resulted in mechanical fasteners that are compatible with belt tension ratings of up to 350kN/m (2,000 PIW). ‘With mechanical fasteners, sift-through of carried materials is a problem’. To prevent ...

What is the Ideal Conveyor Tension Control System?

10/02/2015  Note: power to move TUP is 2 x belt tension x belt velocity. Most TUP powered winches fall in the 10-20 kW range. Therefore, the transient wave passes through the TUP station and other pulley locations with forces many times their steady-state design rating. We have measured and published transient (shock) waves 10 x or more than their steady-state condition. A gravity TUP self relieves this ...

Belt Conveyor Splicing 101: Mechanical Fasteners Or ...

Mechanical belt splices also carry an advantage when it comes to splicing used belts. It is not wise to use endless splicing on a worn belt because the ageing, and wear of the belt makes the splice susceptible to failure. With mechanical belt splicing, fastener splice strength is maintained without having to worry about contaminants such as oils and dirt making their way into the splice.
