Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
See Fig. 1 to Fig. 6, a kind of fan blade angle quick position regulating mechanism described in a preferred embodiment of the present invention, comprises angular positioning regulator 1, fan blade 2 and wheel hub 3; Described angular positioning regulator 1 comprises the positioning cylinder 11 being arranged on its end face and the plane of orientation 12 being arranged on its other end forms; Described fan blade 2 comprises a root connecting head 21, and described root connecting head 21 is provided with center positioning hole 22, and described positioning cylinder 11 is suitable with described center positioning hole 22; Described wheel hub 3 comprises the attachment hole 31 be arranged on outside it, and described attachment hole 31 is provided with circular groove 32, is provided with positioning groove 33 in described attachment hole 31 one end, and described plane of orientation 12 to be placed on described positioning groove 33 and suitable with it.Described plane of orientation 12 is set with plane of orientation 12 center line as symmetrical line and the some radial direction through hole 13 be evenly arranged.Described root connecting head 21 end-face diameter is to the some radial holes 23 of non-uniform Distribution.Described radial hole 23 and described radial direction through hole 13 form positioning hole, and described radial hole 23 and described radial direction through hole 13 shift to install, and are inserted with alignment pin 4 in described positioning hole.Described wheel hub 3 comprises the first half wheel hub 3-1 and the second half wheel hub 3-2, described the first half wheel hub 3-1 are provided with some first grooves of annular spread, described the second half wheel hub 3-2 are provided with some second grooves of annular spread, and described circular groove 32 is made up of described first groove and the second groove.
During concrete installation, described positioning cylinder 11 inserts in the center hole of root connecting head 21 end face of fan blade 2, and described radial direction through hole 13 determines fan blade 2 and angular positioning regulator 1 relative angle with the radial hole 22 of the non-uniform Distribution of fan blade 2 root connecting head 21 end face; Described plane of orientation 12 attachment hole 31 be placed in outside wheel hub 3 is positioned on groove determines angular positioning regulator 1 and wheel hub 3 fixed position; Described angular positioning regulator 1 inserts in the angle also finally determining fan blade 2 and wheel hub 3 in the attachment hole 31 outside wheel hub 3 after being combined with fan blade 2 root connecting head 21; The positioning cylinder 11 of described center positioning hole 22 size and the degree of depth and described angle adjuster 1 end face adapts; To distribute some radial holes 23 according to angle demand Radial Rotation Error at described fan blade 2 root connecting head 21 end face, and be numbered.In the center hole that the positioning cylinder 11 of described angular positioning regulator 1 end face inserts root connecting head 21 end face of fan blade 2,22 ensure that angular positioning regulators 1 are concentric with the root connecting head 21 of fan blade 2; When the root connecting head 21 end face radial hole 23 of any one fan blade 2 is opposed with the radial direction through hole 13 of angular positioning regulator 1 and when synthesizing positioning hole, all the other radial holes 23 on root connecting head 21 shift to install respectively with the radial direction through hole 13 of angular positioning regulator 1; Alignment pin 4 is inserted with in described positioning hole; Described angular positioning regulator 1 inserts in after being combined with fan blade 2 root connecting head 21 in the circular groove 32 in the attachment hole 31 outside wheel hub 3.
