Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
The design initial stage of double pitch drives, the technology path that can choose are divided into three classes nothing more than: (1), two it is independent
Single pitch drive is engaged in same pitch variable bearings simultaneously, realizes double pitch drive controls；(2), in box body of speed reducer after single input
It is interior to realize dual output through shunting；(3), dual input converges defeated into collaborating in the variable pitch speed reducer cabinet of an entirety after shunting
Out.
It is not need the novel speed reducer of development structure using two independent single pitch drive advantages, but pitch motor
Asynchronism can generate uneven load in output end of reducer, start initial stage once meeting with and carrying coupling variable pitch outside the limit, will cause one
A single driving undertakes two and drives the density of load that should bear, and there are biggish risks.
Using dual output is realized through shunting in decelerating chassis body after single input, but dual output does not solve input terminal power
Flow reduced effect and output end unevenness carry property and becomes apparent from, instead result in the output end two small teeth of output engaged with pitch variable bearings and
The problems such as installation, therefore the technology path is temporarily without new breakthrough.
Dual input converges after shunting into interflow output in the variable pitch speed reducer cabinet of an entirety, can solve lightweight
While power flow is shunted in input terminal, reduce asynchronism bring risk.
It includes: pitch variable bearings, pitch motor, pitch control system that dual input according to the present invention, which shunts pitch drive system,
The variable pitch speed reducer of system and dual input diverter function, core apparatus of the present invention are the variable pitch speed reducer of dual input diverter function.
As shown in Figure 1 and Figure 2, two pitch motors 1 connect with the connecting flange bolt of variable pitch speed reducer main body odd-side 2 respectively
It connects, realizes two independent power flow inputs.Speed reducer main body includes main tank 5 and 2 two parts of odd-side, wherein odd-side major part
Including two input gears 3, output gear shaft 4 and bearing etc..Wherein spline connects between input gear 3 and pitch motor 1.Output
4 bearings at both ends of gear support, and output gear shaft 4 from 2 extension of odd-side be spline.The spline is for completing odd-side and main tank
Between power transmission.
It being bolted between main tank 5 and odd-side 2 by flange, main tank uses two-stage NGW planetary gear transmission mechanism,
Secondary center wheel 6 is connect by spline with odd-side gear shaft 4 in middle main tank, and bearings at both ends support, the power as main tank inputs.
Second level gear ring 7 is bolted with main tank cabinet.Secondary planet frame 8 floats, and fixes three groups of planetary gears thereon.Secondary planet frame
8 are connect with secondary center wheel 9 by spline, and secondary center wheel floats.Three-level gear ring 10 is bolted with main tank cabinet, and three
Grade planet carrier 11 floats, and fixes four groups of planetary gears thereon.Power is reached variable pitch by spline and exports small tooth by third-level planetary frame 11
At 12, by bearing support between the small tooth of variable pitch and cabinet, it is finally completed from bi-motor to the power transmission of the small tooth of variable pitch.
As shown in Figure 1, Figure 3, pitch motor and speed reducer main body connection structure, odd-side structure and the first dual input point
Stream (planetary gear train) structure is identical, and main difference is embodied in the gear-driven driven Design of main tank.
Its main tank is designed using centre drive: secondary center wheel 13 passes through spline and odd-side output gear shaft in main tank
4 are connected, and odd-side power are reached main tank, secondary center wheel 13 in main tank, by nibbling with the canine tooth of three dead axle transmission gears 14
It closes, realizes decelerating effect.Dead axle transmission gear is connect by the support of dead axle bearing 15 with main tank cabinet.Dead axle transmission gear simultaneously
14 small tooth is engaged with main tank output gear 16, realizes power interflow.Output gear 16 is fixed by bearing and cabinet, passes through flower
Power is reached variable pitch and exported at small tooth 12 by key.It is finally completed from bi-motor to the power transmission of the small tooth of variable pitch.
The single pitch drive of comparison tradition and the double electric pitch-controlled systems constituted using two independent electric pitch drives, the present invention
The dual input of proposition shunts pitch drive transmission system and has the advantage that
1, dual input shunting pitch drive system space is compact, is suitble to big megawatt of machine unit hub space layout condition.Although
Dual input shunts than one electric pitch drive volume of tradition of pitch drive and increases, but with two independent tradition electricity pitch drives
It is obvious that amplitude is reduced compared to still volume and weight.
2, dual input shunts pitch drive system and effectively prevents what two independent electric pitch drive asynchronisms generated
Risk.Even if two motors also have 1 since two independent pitch motors are run under very outstanding pitch control strategy
The synchronous error of~2 electric signal pulses, this generates the uneven influence carried to traditional output end of reducer strength of gear teeth.It uses
At the time of double pitch motor drive forms must calculate ultimate load in detail and occur: if variable pitch instruction is possible to meet with during issuing
Carry outside the limit, then occur before variable pitch movement at the time of the limit must be avoided to occur, according to this guaranteeing double variable pitch speed reducers because
It is asynchronous and make wherein speed reducer export small tooth and individually bear whole ultimate loads in variable pitch starting moment.And this dual input
It shunts pitch drive system and only generates the asynchronism of two pitch motors in speed reducer first order input terminal, it is contemplated that slow down
Though machine input terminal revolving speed is big but input stage load is small, operating condition is carried outside the limit even if meeting with, by asynchronism when being transmitted to the first order
It engages one of input terminal parallel gears first with first order centre wheel, catastrophe failure will not be generated.
3, it is convenient to shunt variable pitch speed reducer breakdown maintenance processing for dual input.It is located at speed reducer due to shunting deceleration parallel stage
Input unit dress, even if asynchronism occur generates parallel stage gear wear or broken teeth failure, maintenance replacement operation facilitates easy
Row；If since asynchronism causes to export small tooth generation and pitch variable bearings canine tooth generation abrasion or broken teeth failure, later period failure dimension
Shield processing will bring numerous difficulties.
4, dual input shunts variable pitch speed reducer processing and manufacturing precision and is relatively easy to control.Two independent single electric pitch drives are defeated
Required at small tooth with the cooperation of the pitch variable bearings ring gear Gear Processing accuracy of manufacture out it is not easy to control (gear of output end modulus compared with
Greatly)；And it is designed to that dual input shunts form in input terminal, since input end gear modulus is smaller, Gear Processing precision is relatively easy
It controls, the uneven of generation carries property also relation control.
5, simple as double pitch drive structures of main box design form using planetary gear train, easy to produce and installation.
The second level and the third level use traditional gear for two stage planetary gear train structure, can reduce on the basis of meeting the density of load and requiring total
Body weight.
6, double pitch drives using center driving train as main box design form can improve while loss of weight
The torque density of speed reducer, and bearing lubrication efficiency can be improved using fixing bearing design form.Main box is passed using center
Dynamic structure design, can save two-stage gear ring, save planetary gear pin shaft and planet carrier, and relative weight mitigation, which can also be promoted, entirely to be subtracted
The bearing capacity of fast machine；The thinking designed using fixing bearing, can allow the lubrication of bearing more thorough.
7, two yaw motors are switched equipped with limiting steering, prevent two motors from rotation function not in the same direction occur.In variable pitch
Increase limiting steering exploitation in motor power supply control strategy, can be effectively prevented because the reasons such as maloperation lead to two variable pitch electricity
Machine work rotation direction is inconsistent and then brings the failures such as speed reducer broken teeth.
