Technical field:
The utility model relates to the checkout equipment technical field, particularly the dynamic balancing measurement device.
Background technology:
Dynamic balance measuring instrument is an instrument of measuring rotating object amount of unbalance size and position.
Any rotating object is around its axis rotation the time, owing to the non-uniform mass with respect to axis produces centrifugal force.This uneven centrifugal action can cause vibration on the rotating object bearing, produce noise and quicken bearing wear, so that have a strong impact on the performance and the life-span of product.Rotation such as fan parts all need could steadily normally turn round through overbalance in manufacture process.
According to the data that dynamic balance measuring instrument is measured the amount of unbalance of rotating object is proofreaied and correct, can improve the mass distribution of rotating object with respect to axis, vibration that produces when making the rotating object rotation or the vibration force that acts on the bearing reduce within the scope of permission.Therefore, dynamic balance measuring instrument is to reduce the imperative equipment vibrating, improve performance and improve the quality.
For the demanding rotating object of balance, generally adopt centrifugal single or double dynamic balance measuring instrument.
The centrifugal balance tester is under the state of rotating object rotation, the supporting vibration that causes according to the rotating object imbalance, or the vibration force that acts on supporting is measured imbalance.It presses the difference of correcting plane quantity, can be divided into single face dynamic balance measuring instrument and two-sided dynamic balance measuring instrument.The single face dynamic balance measuring instrument can only be measured an imbalance (static unbalance) on the plane, though it is to measure when rotating object rotates, but still belongs to the static equilibrium tester.The unbalance dynamic of two-sided dynamic balance measuring instrument energy measurement also can be measured static unbalance and couple unbalance respectively, is commonly referred to as dynamic balance measuring instrument.
