Description
Technical field
The utility model relates to technical field of wind power generating equipment, especially relates to a kind of Large-scale Wind Turbines dependent hydraulic vane change actuator.
Background technique
The large medium size wind generator major part that the whole world is put into commercial operation have employed feather technology, and blade pitch device ripe at present mainly contains electric variable pitch and on-electric becomes two kinds, oar.Electric variable pitch complex structure, needs the change oar drive motor be routed to from the cabin power supply of geo-stationary by cable inside the wheel hub of rotation, therefore needs the parts slip ring of a cost intensive.On-electric becomes oar and generally adopts ball screw form, this structural type drives ball screw by the motor being positioned at cabin, be straight line motion by converting rotary motion, being converted to circular movement by linkage mechanism again drives pitch variable bearings to rotate, structure is more complicated, transmission efficiency is lower, there is the shortcomings such as rollers wear is stuck, lubrication is not smooth.
Summary of the invention
Problem to be solved in the utility model is: effectively improve mechanism reliability and transmission efficiency while of reducing pitch-controlled system cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is a kind of Large-scale Wind Turbines dependent hydraulic vane change actuator, and it, by a kind of space four bar linkage mechanism, realizes object straight line motion being converted to circular movement.The utility model critical piece comprises rocking arm, bearing inner race, bearing outer ring, expansion sleeve, tri-claw disk, push rod, block, bearing pin, sliding bearing A, connecting rod, sliding bearing B and other accessories, such as bolt, snap ring, packing ring etc., this programme number of components is 3 covers except push rod, expansion sleeve, tri-claw disk, connects 3 blades (only showing 1 cover for expressing clear diagram herein) respectively.Push rod is connected with tri-claw disk by expansion sleeve, tri-claw disk to be connected with connecting rod by bearing pin and sliding bearing A and to use block to adjust connecting rod both sides joint gap, connecting rod is connected with rocking arm with sliding bearing B by bearing pin, and sliding bearing has self-lubricating effect, without the need to the manual application of lubricant; Rocking arm is bolted to bearing inner race, and bearing outer ring is fixed on wheel hub, and wherein rocking arm, connecting rod, tri-claw disk, push rod composition space four bar linkage mechanism, convert the circumgyration campaign of bearing to by the straight reciprocating motion of push rod.
Push rod by and hydraulic jack (or other Power Drive Units) drive, do straight reciprocating motion, drive simultaneously with it by expansion sleeve be connected tri-claw disk do straight reciprocating motion; Tri-claw disk to be connected with connecting rod by bearing pin and sliding bearing A and to use block to adjust joint gap, rotates while connecting rod does straight line motion around bearing pin; Connecting rod is connected with rocking arm with sliding bearing B by bearing pin, and drives rocking arm to rotate around bearing pin; Rocking arm is bolted to bearing inner race, and bearing outer ring is fixed on wheel hub (fixed frame), and the rotating band moving axis of rocking arm makes circumgyration campaign.Straight line motion is converted to circular movement by whole mechanism.
The advantage that the utility model has and good effect are: rocking arm, connecting rod, tri-claw disk, push rod composition space four bar linkage mechanism, converts the circumgyration campaign of bearing to by the straight reciprocating motion of push rod.Expansion sleeve connects push rod and tri-claw disk, connects reliable and can adjust push rod length, reducing processing and build-up tolerance requirement; All rod members all move in single plane, and parts connecting rod becomes the simplest two power bars, and simply stressed, structure is reliable; Self-lubricating plain bearing is reliable, unmanned.
