Some tension devices will make this adjustment by increasing or decreasing the distance between the terminal pulleys (i.e., head and tail pulleys in Figure 1) on the conveyor. Other systems will employ additional pulleys along the conveyor

More DetailsTransferring from power to gravity sections. When transferring a package from a power conveyor to a gravity curve, a straight section of gravity conveyor at least as long as the longest package to be conveyed should precede the curve. This is recommended because the force of the belt may be greater than the force of the curve, resulting in the package overshooting the curve.

Here we consider a rubber belt moving between two cylinders, see Fig. 1.One cylinder (pulley) is forced to rotate with the constant rotation speed ν R = ωR (where ω is the angular velocity and R the cylinder radius). If T 1 and T 2 are the tension (here defined as the force divided by the (lateral) width w of the ...
More DetailsTension in a conveyor belt is fundamental to its very operation in terms of supporting the load between rollers and enabling the drive to impart motion to it. For a conveyor on the verge of slipping, there is a direct ratio between T1, the traction force imparted to the Conveyor and T2, the Take-Up Tension, of a Conveyor Belt. This ratio is of the

More DetailsAs shown in the figure below (Figure A), the tension on the belt is accomplished by turning the screw at the end of a conveyor. This pushes the bearing block towards the end of the conveyor, which adds tension to the belt. There is another, identical jack-screw located on the opposite side of the roller.
