Protrude on the surface that the same quiet disk 102 of platform 108 is relative.Moving plate 103 is installed on the outside of convex frame 109 and turbulence blades 105 are arranged at
In convex frame 109.Top and the surface (figure of Moving plate 103 of the turbulence blades 105 preferably in the axial direction of rotating shaft 104 with convex frame 109
Upper surface in 2) highly flush.Because the gap between quiet disk 102 and Moving plate 103 is generally smaller, so above-mentioned three
Flush and just in the gap can form air-flow on the premise of small gap is kept as far as possible.
In addition, Moving plate 103 and convex frame 109 can be annular in shape, and the annular inner race of Moving plate 103 and the annular of convex frame 109
Outer ring offsets, as depicted in figs. 1 and 2.
Turbulence blades 105 can include being in the radial multiple blades in center.It is used as a preferred embodiment, multiple blades
In each perpendicular to carrying platform 108.As shown in figure 1, rotating shaft 104 is connected with motor, it is set operationally may be used
To be turned clockwise or rotate counterclockwise under the driving of motor.Therefore, perpendicular to the blade of carrying platform 107
Equal air-flow can be all produced turning to any of clockwise and anticlockwise.
In the embodiment shown in Fig. 1 and Fig. 2, the center of turbulence blades 105 is provided with perforation, and carrying platform 108
Center be provided with screw.The structure allows turbulence blades 105 to be removably installed in carrying platform 108 by screw 112.
Certainly, the utility model is it is also possible that turbulence blades 105, axostylus axostyle 107, carrying platform 108 and convex frame 109 are integrally formed,
Such as integrated injection molding or integrally casting.
Further, encoder 100 may further include supporting member 110.Supporting member 110 with housing 101 coordinate with
Form the space for accommodating quiet disk 102 and Moving plate 103.Rotating shaft 104 runs through to be set between supporting member 110 and rotating shaft 104 and supporting member 110
It is equipped with bearing 111.
To form more preferable air-flow in the space that the housing 101 and supporting member 110 of encoder 100 are formed, preferably exist
It is provided with least one passage 106 offered on the quiet disk 102 of circuit module 113 through quiet disk 102.Shown in Fig. 3
In embodiment, the passage 106 is the round vent for being arranged at the quiet center of disk 102, and the radius of the round vent is ibid
The length of blade for stating turbulence blades 105 is suitable.Or, in another embodiment shown in Fig. 4, the passage 106 can also be by
Multiple less passages are constituted, and the shape of these passages is not particularly limited.Compared with the embodiment shown in Fig. 3, Fig. 4's
Many ventilation well formats allow quiet disk 102 to have bigger surface area, so as to set more components on quiet disk 102
(such as more circuit modules 113).It therefore, it can the embodiment in Fig. 3 and Fig. 4 according to the circuit design requirements of quiet disk 102
Between selected.
At least one passage 106 with turbulence blades 105 in the axial direction of rotating shaft 104 it is positioned opposite to each other.In other words,
Preferably so that passage 106 is located at the top of turbulence blades 105, so that air-flow is in the form shown in Fig. 1.That is, quiet disk 102
The air-flow in gap between Moving plate 103 under edge flowing from the drive of turbulence blades 105 to encoder 100, passed through after
The top for being blocked in quiet disk 102 of housing 101 is again to the center flow of quiet disk 102, finally by positioned at the center of quiet disk 102
