Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art and provide a kind of and utilize rubber elastic element to replace metal spring to reach vibration damping, eliminate different sound, reduce the reject ratio of radiation fan in making, transportation process, prolong element working life, promote the brush DC radiation fan of radiation fan quality.
The purpose of this utility model can reach by following measure:
This brush DC radiation fan, comprise the supporting base that has the hollow type drum shape body, position, the tubbiness center of circle bearing set of supporting base, motor stator is sleeved on the tubbiness external peripheral surface of supporting base, the heat radiation rotor cover that has a rotating shaft is packed in the bearing centre hole, tail end in rotating shaft fastens the clasp that plays the role of positioning, and it is characterized in that: several rubber elastic elements of suit in the rotating shaft.
The purpose of this utility model can reach by following measure:
Rubber elastic element is installed between flabellum rotor and the ball bearing.
Rubber elastic element is installed between clasp and the ball bearing.
Rubber elastic element is the structure that hollow, excircle are the indent parabolic shape.
Rubber elastic element is a hollow columnar structures.
Rubber elastic element is a circular ring.
Rubber elastic element is hollow and is E type structure by cross section, the center of circle.
The utility model has following advantage compared to existing technology:
1, reduce to make and transportation process in reject ratio, improved the up-to-standard rate of product.
2, effectiveness in vibration suppression is remarkable.
