Description
Technical field
This utility model belongs to a kind of wind turbine component, and a kind of wind electricity change paddle for connecting gear-box is sliding
Ring.
Background technology
In wind-driven generator field, wind turbine gearbox afterbody is commonly connected directly to wind electricity change paddle slip ring, gear-box band wind symptom
The flange of electric slip ring rotates, and power is further delivered on output shaft through flange.
Traditional power delivery mode is that flange and output shaft connect, due to complete blower height by lock-screw is fixing
All more than 70 meters, working environment is with slosh and random oscilation, and output shaft is all mounted on bearing block use, passes through
Investigation, finds that a lot of wind-power slip ring occurs in that circuit eccentric wear even off-axis phenomenon, and analysis result shows, these faults and accident are all
Due to rotating shaft with flange coaxiality is inconsistent causes, being connected fixing to rotating shaft and flange by screw, direct rigidity connects
Touch, under this severe operating mode of blower fan, between output shaft and flange, there is the distortion that different spindle guide causes.Cause circuit eccentric wear,
Wind-power slip ring is substantially reduced service life, even off-axis, and slip ring is scrapped, and blower fan is stopped transport.
Utility model content
The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that a kind of wind pitch gear box
Slip ring, this wind pitch gear box slip ring makes flange be connected with gear-box semi-flexible, strong to the adaptivity of axiality, prevents
Significantly shock and vibration are delivered on output shaft.
The purpose of this utility model can be realized by following technical proposal: a kind of wind pitch gear box slip ring, including
The output shaft of gear-box, wind-power slip ring flange, the axle head of described output shaft is connected by driving lever with the flange of wind-power slip ring, i.e. exists
The axle head of output shaft is provided with several driving lever, is provided with and the driving lever hole of described driving lever matched in clearance, output shaft at flange end
With flange by driving lever stir transmission energy.It is provided with spring bearing, bearing pair between flange and the gear-box of wind-power slip ring
Flange plays main supporting function.
Ensureing between flange and output shaft on the premise of power normal delivery, the lock-screw of flange and output shaft is solid
Even mode, is improved to big shaft strength, and flange stirs output shaft rotation by stirring screw rod, solves due to flange or defeated
The problems such as shaft working axiality is poor, bearing clearance causes bias, assembling cumulative errors cause flange and output shaft is the most coaxial.
In above-mentioned wind pitch gear box slip ring, described driving lever one end has the axle head of screw thread, driving lever and output shaft
It is threaded connection.
In above-mentioned wind pitch gear box slip ring, the axle head of described output shaft is also equipped with driving lever hole, driving lever one
In the driving lever hole that end is slidably inserted on axle head, the other end of corresponding driving lever, in flange, it is provided with sliding electromagnet, driving lever
It is connected with the push-pull bar of sliding electromagnet.Sliding electromagnet realizes driving lever insertion in axle head driving lever hole or pull-out, with limit root
According to needing the power cutting off between flange and axle to transmit, Accident prevention occurs.
In above-mentioned wind pitch gear box slip ring, described flange is provided with spring bearing sealing ring.
Compared with prior art, this wind pitch gear box slip ring has the advantage that
This utility model is ensureing between flange and shaft core on the premise of power normal delivery, by flange and the locking of shaft core
Screw attachment, is improved to big shaft strength, and flange stirs shaft core rotation by stirring screw rod, completely solves due to method
Blue or shaft core working axiality is poor, bearing clearance causes bias, assemble cumulative errors causes flange and shaft core is the most coaxial etc. asks
Topic.
