    Jul 09, 2013 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. so belt above pulleys will have higher tension, hence belt below pulleys form slack side

    Launch the conveyor belt in the reverse run, to the tail pulley. The belt must be empty. Check it during three entire revolutions. Re-launch the conveyor in the current direction and wait another three revolutions. Rectify the tension to center of the belt: if you tighten on the left side, the belt must moves to the right (See figures B & C)

    All conveyors require an additional belt tension in order to allow the pulley to drive forward an effective tension without slipping. In a case of a simple horizontal conveyor T1 is the sum of the effective tension Te and the slack side, the tension T2. T 1 = T e + T 2 = For the inclined conveyor, additional tensions are induced due

    Mar 23, 2021 The slack side is the side where tension on a belt is low compared to the other side. In a flat belt drive, driver pulley pulls the belt through the bottom side and deliver it on the opposite side (upper side), so the top side is always loose. One of the reasons for doing so is to increase the angle of contact

    The Average belt tension remains constant at the preset setting so when the conveyor runs and the drive tension increases on the tight side, there is a corresponding drop in tensions on the return side belt. This drop in T2 tension means that an additional tension is required in the system to ensure that there is sufficient drive traction

    The belt has one area in the belt drive where the tension is more than the other side. That side is called the tight side. The other area where tension is less is called the slack side. On the tight side, due to tension, the belt length increases, and on the slack side, due to compression, the belt size decreases
