Description
Technical field
This utility model belongs to encoder techniques field, and it is double that more particularly, to a kind of wind-driven generator pitching and driftage use
Layer coder.
Background technology
Driftage on blower fan or change oar all can use encoder, constantly to grasp driftage and to become paddle state, and according to anti-
The information of feedback makes next step driftage and the instruction becoming oar.But for convenience of installation, generally existing between current encoder device and gear
The gap of 1.5-2.0mm, as shown in fig. 7, when changing driftage or becoming oar direction, this gap can cause to go off course and become oar error,
Lead to impeller Windward angle or vane propeller-changing angular error, affect wind energy utilization.
Therefore, in order to solve the gap error of encoder and gear, accurately go off course and become oar, improve wind energy utilization, therefore
The technical scheme of double-layer gear encoder is proposed.
Utility model content
This utility model overcomes the deficiency of above-mentioned technology, there is provided it is double that a kind of wind-driven generator pitching and driftage use
Layer coder, by increasing by one layer of gear, inside and outside two-layer gear is slightly misaligned, to solve encoder and the meeting of Bearing gear gap
Cause the problem going off course and becoming oar error.
For achieving the above object, this utility model adopts following technical proposals：A kind of wind-driven generator pitching and driftage make
Double-deck encoder it is characterised in that：Including inboard gear and outboard gears, described inboard gear is in circle left large and right small
Shape boss-shaped, is provided with through hole at axle center, and matches with encoder axle, is provided with pin shaft hole on the periphery of right-hand member small boss,
Pin shaft hole is connected with encoder axle by bearing pin, and inboard gear is arranged with two with the center of circle on the end face of the big round platform of left end
Fix bar, described outboard gears are in round pie, be provided with through hole, and match with encoder axle at axle center, and outboard gears are at end
Respectively two fix bars and two waist-shaped holes are arranged with the center of circle on face, two on described inboard gear piece fix bar is from outside
Two waist-shaped holes on gear pass through, and are connected with extension spring between described inboard gear and the fix bar of outboard gears, described
Encoder axle inboard gear and outboard gears assembling after both sides end face axle on be respectively provided with one for preventing axial string
Dynamic jump ring.
Compared with prior art, the beneficial effects of the utility model have：
1st, pass through inboard gear and outboard gears constitute double-layer gear design, eliminate original design middle monolayer gear and encoder
Between gap, can accurately go off course and become oar, improve wind energy utilization.
2nd, by extension spring, the fix bar of inboard gear is connected with the fix bar of outboard gears, not only ensure that and disappear
Except the feature of encoder and gear clearance, encoder is also made still easily to fill, workable, the design limit of snap ring inner side
Gear and the axial motion of outboard gears, so that encoder can be installed at any angle, strong applicability.

Specific embodiment
With reference to the accompanying drawings and examples, this utility model is further described, but is not limited to embodiment.
Embodiment 1
As shown in Figures 1 to 6, the double-deck encoder of a kind of wind-driven generator pitching and driftage use, including inboard gear 1 He
Outboard gears 4.Described inboard gear 1 is in round boss shape left large and right small, is provided with through hole at axle center, and with encoder axle 7
Match, pin shaft hole 3 is provided with the periphery of right-hand member small boss, pin shaft hole 3 is connected with encoder axle 7 by bearing pin 9, interior
Side gear 1 is arranged with two fix bars 2 with the center of circle on the right end face of the big round platform of left end.
Described outboard gears 4 are in round pie, be provided with through hole, and match with encoder axle 7 at axle center, outboard gears 4
End face is arranged with two fix bars 2 and two waist-shaped holes 5 with the center of circle respectively, two fixations on described inboard gear 1
Two waist-shaped holes 5 from outboard gears 4 for the bar 2 pass through, and connect between described inboard gear 1 and the fix bar 2 of outboard gears 4
There is extension spring 6, described encoder axle 7 is respectively provided with the axle of the both sides end face after inboard gear 1 and outboard gears 4 assembling
One jump ring 8, and inboard gear 1 and outboard gears 4 axial motion on encoder axle 7 is prevented by jump ring 8.
This utility model is passed through with one heart by two-layer gear and can relatively rotate between encoder axle, and two side gears, wherein
Inboard gear has boss, so that it is fixed with encoder axle with bearing pin, and therefore the anglec of rotation of inboard gear is and goes off course or become oar
Accurate angle, inboard gear and outboard gears pass through mounting hole and spring is radially connected, and spring uses extension spring, both ensures
Interior outboard gears can in assembling process adjustment position, when in turn ensure that change driftage and becoming oar direction, between can eliminating
Gap error, accurate feedback angle information.
Because encoder needs to adjust installation direction according to position of bearings, such as hub bearing encoder, installation direction not level,
And the rotation with wheel hub, encoder gear is also by centrifugal force.So inboard gear and outboard gears carry out axle by jump ring
To spacing, as shown in Figure 6, it is to avoid it occurs axial motion, affect result precision.
