The YQW-100is a special balancer for dynamically balancing crank shafts with end coupling drive.It couples rotor end to coupling,the coupling has a very velocity of movable fastening part and easy operation.This balancer has a specially designed measuring unit of balancing crank shafts.The balancing crank shafts measuring unit can easy changes a-b-c dimension for the convenience of adoptable correcting planes.It features hard bearing,very velocity end coupling drive,high efficiency and easy operation.The amount of unbalance of workpieces in unit of grams and phace angle are correctly indicated in a single running.It is ideal for crank shaft rotors and crank shaft flywheel clutch are composed in part of different types in small serial production.It is a necessary ideal equipment of crank shaft factory.

       The indication unit adopts spotlight-vector which provides a direct reading.Digital-analog IC is mainly used in the measuring system with"double channel","holding","static","couple"and "test"functions thus of fering a good balancing result.
