Embodiment
Characteristic on above-mentioned purpose of the present invention and structure and fuction thereof, is explained the preferred embodiment according to institute's accompanying drawings.
Below in conjunction with concrete drawings and Examples, the invention will be further described.
Characteristic on above-mentioned purpose of the present invention and structure and fuction thereof, is explained the preferred embodiment according to institute's accompanying drawings.
Refer to Fig. 1,2, for the decomposition of the first embodiment of fan shock absorption structure of the present invention is analysed and observe and assembled sectional view, as shown in the figure, described fan shock absorption structure 1, comprising: beam barrel 11, clutch shaft bearing 12,1 second bearing 13, the 3rd bearing 14, elastic element 15 and at least one oil sealing 16 and the viscid several grease 17 of height;
There is in described beam barrel 11 containing space 111 and an axis hole 112, described axis hole 112 is connected with aforementioned containing space 111, and this clutch shaft bearing 12 and second and third bearing 13,14 and elastic element 15 and oil sealing 16 are installed with in the inner, and in this containing space 111, be filled with high viscid several grease 17.And in the containing space 111 of described beam barrel 11, radial projection one stopper 113, this stopper 113 has the function of axial limiting.
