Description
Technical field
The invention belongs to encoder techniques field, particularly relate to the double-deck coding of a kind of wind-driven generator pitching and driftage use
Device.
Background technology
Driftage on blower fan or change oar all can use encoder, in order to grasp driftage constantly and become paddle state, and according to instead
The information of feedback makes next step driftage and the instruction becoming oar.But for convenience of installing between current encoder device and gear, generally exist
The gap of 1.5-2.0mm, as it is shown in fig. 7, when changing driftage or becoming oar direction, this gap can cause driftage and become oar error,
Cause 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 driftage and change oar, improve wind energy utilization, therefore
The technical scheme of double-layer gear encoder is proposed.
Content of the invention
Instant invention overcomes the deficiency of above-mentioned technology, provide the double-deck volume of a kind of wind-driven generator pitching and driftage use
Code device, by increasing by one layer of gear, inside and outside two-layer gear is slightly misaligned, and can cause to solve encoder and Bearing gear gap
Driftage and the problem becoming oar error.
For achieving the above object, the present invention uses following technical proposals: a kind of wind-driven generator pitching and driftage use
Double-deck encoder, it is characterised in that: including inboard gear and outboard gears, the circle that described inboard gear is left large and right small is convex
Mesa-shaped, is provided with through hole, and matches with encoder axle, be provided with pin shaft hole, bearing pin on the periphery of right-hand member small boss at axle center
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 and fixes
Bar, described outboard gears is round pie, is provided with through hole, and matches with encoder axle at axle center, and outboard gears is on end face
Being arranged with two fixing bars and two waist-shaped holes with the center of circle respectively, the fixing bar of two on described inboard gear piece is from outboard gears
On two waist-shaped holes pass through, be connected with stretching spring, described volume between described inboard gear and the fixing bar of outboard gears
It is respectively provided with one for preventing axial motion on the axle of both sides end face after inboard gear and outboard gears assemble for the code device axle
Jump ring.
Compared with prior art, beneficial effects of the present invention has:
1st, pass through inboard gear and outboard gears and constitute double-layer gear design, eliminate in former design between individual layer gear and encoder
Gap, can accurately go off course and become oar, improve wind energy utilization.
2nd, by stretching spring, the fixing bar of inboard gear is connected with the fixing bar of outboard gears, not only ensure that and disappear
Except the feature of encoder and gear clearance, also making encoder still easily fill, workable, the design of snap ring limits inner side
Gear and the axial motion of outboard gears, so that encoder can be installed at any angle, applicability is strong.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the present invention is further illustrated, but is not limited to embodiment.
Embodiment 1
As shown in Figures 1 to 6, the double-deck encoder that a kind of wind-driven generator pitching and driftage use, including inboard gear 1 and outside
Gear 4.Described inboard gear 1, in round boss shape left large and right small, is provided with through hole, and matches with encoder axle 7 at axle center
Closing, being provided with pin shaft hole 3 on the periphery of right-hand member small boss, pin shaft hole 3 is connected with encoder axle 7 by bearing pin 9, inner tines
Wheel 1 is arranged with two fixing bars 2 with the center of circle on the right end face of the big round platform of left end.
Described outboard gears 4, in round pie, is provided with through hole, and matches with encoder axle 7 at axle center, outboard gears 4
Being arranged with two fixing bars 2 and two waist-shaped holes 5 with the center of circle respectively on end face, two on described inboard gear 1 fix
Two waist-shaped holes 5 from outboard gears 4 for the bar 2 pass through, and connect between described inboard gear 1 and the fixing bar 2 of outboard gears 4
There is stretching spring 6, the axle of both sides end face after inboard gear 1 and outboard gears 4 assemble for the described encoder axle 7 is respectively provided with
One jump ring 8, and prevent inboard gear 1 and axial motion on encoder axle 7 for the outboard gears 4 by jump ring 8
The present invention is passed through with one heart by two-layer gear and can relatively rotate between encoder axle, and two side gears, wherein inboard gear
Having boss, making it fix with encoder axle with bearing pin, therefore the anglec of rotation of inboard gear is driftage or becomes the accurate angle of oar
Degree, inboard gear passes through mounting hole with outboard gears and spring is radially connected, and spring uses stretching spring, both ensure that interior outside
Gear can adjust position during assembling, when in turn ensure that change driftage and become oar direction, can eliminate gap error, essence
True feedback angle information.
Because of encoder need according to position of bearings adjust installation direction, such as hub bearing encoder, installation direction not level,
And with the rotation of 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, affects result precision.
