State the harmomegathus that split surface is used for periphery diameter.
Preferably, dismounting adjustment bolt is provided with the ringfeder.Described dismounting adjustment bolt is used for the dismounting of ringfeder；
Round nut is pulled down after the completion of dynamic balance calibration, then extracted from wheel bore ringfeder out by rotating dismounting adjustment bolt.
The utility model when in use, according to the suitable axially adjustable set of axial dimension selection of rotor hub, will couple
After key is assembled in main shaft, axially adjustable set, rotor hub, ringfeder and round nut in tandem successively.Fastening round nut is allowed to extruding and risen
Set, ringfeder move to the big end of circular cone, increase ringfeder external diameter；Finally, the endoporus of the cylindrical and rotor hub of ringfeder produces tight
Close fit, so as to ensure the assembly precision of rotor hub and main shaft.
The beneficial effects of the utility model are：
1. interchangeable expansion sleeve type dynamic balancing axle described in the utility model；Ringfeder diameter is adjustable, by changing rising for different-diameter
Set and axially adjustable set are applicable different diameter of bores and the fan rotor of axially different size, avoid fixed dynamic balancing
The existing frequent dismounting of axle correction causes dynamic balance calibration precise decreasing, influences the quality of Fan Product and asking for production cycle
Topic, and reduce the maintenance cost of dynamic balancing axle and process the expense of dynamic balancing axle corresponding to different diameter of bore rotors.
