FAN BALANCING DEVICE AND FAN BALANCING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a fan balancing device capable of accurately and efficiently balancing a rotary fan. ;SOLUTION: A fan balancing device includes a dynamic balance tester 50 provided with a collet chuck 52a for measuring the unbalance amount of a cross flow fan 10, a controller 100 for calculating position data for a fin to mount a balance weight thereon in accordance with the unbalance amount and weight data for the balance weight mounted on the fin and a balance weight mount 60 for mounting the balance weight on the fin in accordance with the position data for the fin 14 obtained by the controller 100 and the weight data for the balance weight. Nine factors for performing highly precise measurement and maintenance by using the device are clarified and a mechanism and an algorithm are assembled in the device to meets these factors.;COPYRIGHT: (C)1999,JPO
