Static and Dynamic Balancing Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-FMAHLE-7333
Jlab Export is a leading Static and Dynamic Balancing Apparatus Manufacturer,and suppliers in India
Static and Dynamic Balancing Apparatus (code EL-FMAHLE-7333) is a rotating-mass rig in which four clamped blocks on a steel shaft, fixed in a rectangular frame, are first balanced statically and then dynamically. Angular and longitudinal scales locate each block, and a motor spins the shaft so the result can be checked while it runs. JLab manufactures the frame, shaft and block set in Ambala, India.

Measuring Each Block
For the static stage, each block is clamped on the shaft by itself and its relative weight is found with the cord and container system, counted as the number of steel balls needed. This figure stands for the block’s out-of-balance effect, the product of its mass and the radius of its centre of mass.
From Static to Dynamic Balance
Static balance needs the out-of-balance effects of all blocks to cancel, so the shaft rests at any angle. That alone does not stop a rocking couple when blocks sit at different points along the shaft. For dynamic balance their moments about a reference plane must cancel too: a moment polygon drawn from the relative weights gives the angular and axial position of each block. The blocks are set to those positions on the scales, the frame is hung from its chains, and the motor spins the shaft. A balanced shaft runs without shaking the frame, while a misplaced block shows the effect of unbalance clearly.
