Description
Technical field
The present invention relates to wind-driven generator technical group field, in particular to a kind of brake system and outer rotor type direct drive wind-force
Generating set.
Background technique
Wind power generating set can be divided into two types by transmission chain pattern: gear box-typed wind power generating set and direct-driving type
Wind power generating set.So-called gear box-typed wind power generating set is exactly that step-up gear is arranged between wind wheel and generator,
Generator is driven to generate electricity by step-up gear.So-called direct-driving type wind power generation unit is exactly that wind wheel and generator directly connect
It connects.
Direct wind-driven generator group can be divided into outer rotor type direct drive wind power generating set and the straight wind dispelling of inner-rotor-type again
Two kinds of power generator group.A kind of typical outer rotor type direct drive wind power generating set generally includes wind wheel, rotor and stator, rotor
Under the drive of wind wheel, make rotating motion around stator.Rotor generally comprises rotor room, and permanent magnet, rotor is arranged in rotor within doors
Room and permanent magnet follow rotor to make rotating motion together.In general, stator includes stator coil, stator coil cuts rotary motion
The magnetic field that permanent magnet generates, and then complete power generation.
Occur for the ease of maintenance, or reply fortuitous event, outer rotor type direct drive wind power generating set is usually additionally provided with
Wind wheel locking and brake system, wind wheel locking and brake system are generally locked by brake disc (can also be known as revolving part), wind wheel
The components such as pin and brake (can also be known as non-rotating part) are constituted.Brake disc is generally arranged on rotor room, for the ease of with
Brake disc matches, and wind wheel locking pin and brake are both needed on setting supporting element.
When outer rotor type direct drive wind power generating set is when braking or locking wind wheel, brake load and wind wheel locking load will
It is acted directly on rotor room by brake disc, above-mentioned load will lead to rotor room and bear biggish stress, which will lead to
The structure of outer rotor type direct drive wind power generating set deforms, and particularly results in rotor room and deforms.It is above-mentioned in order to overcome
Load influences rotor room bring, and the rotor room of outer rotor type direct drive generating set is in design it has to be ensured that having enough
Strength and stiffness, therefore, the material cost for resulting in rotor room greatly increase.
In addition, since the outer diameter in rotor room is bigger, brake disc is for mount on rotor room, the outer diameter of brake disc
Size must also accordingly increase.Therefore, cause brake disc overall dimensions excessive, increase brake disc weight and manufacture at
This.
Meanwhile in order to be matched with brake disc, when installing wind wheel locking pin and brake, the securing supports of the two
It must be close to the internal diameter of wind wheel brake disc, the size for also resulting in the securing supports of the two as a result, is also bigger, increases outer
The weight and manufacturing cost of rotator type direct wind-driven generator group.
In conclusion current outer rotor type direct drive wind power generating set has the disadvantage that the brake due to brake system
It is larger that hull (namely revolving part) needs to be mounted on the stress for causing rotor room to bear on rotor room, so that rotor room be made to hold
Easily deform.Meanwhile the ruler of the securing supports of the wind wheel locking pin and brake (namely non-rotating part) of brake system
Very little larger, manufacturing cost is higher.
