Abstract
The utility model provides a yaw brake disc for a wind turbine generator. The brake disc comprises a fixing ring, a demountable brake disc and a fastener, wherein the fixing ring is fixedly connected with a cabin seat of the wind turbine generator, the demountable brake disc is connected with the fixing ring through the fastener, and the demountable brake disc can be formed by a plurality of split type brake discs. The brake disc provided by the utility model has a reasonable structural design, is convenient to use, install and disassemble, and can greatly lower the maintenance cost of the replacement of the brake disc in a wind power scene, guarantees the normal operation of the wind turbine generator, and more facilitates the maintenance.
Description
Technical field
The utility model relates to the driftage brake part, particularly a kind of wind-powered electricity generation unit yaw brake disc.
Background technique
Wind energy more and more is subject to the attention of countries in the world as a kind of renewable energy sources.From 2006, the MW class wind turbine group becomes the generator set of domestic main flow gradually, in order to make blower fan possess the larger wind efficient of catching, all Megawatt fans must possess the driftage ability, all the time towards certain direction, in blower fan, installed yaw system when making the blade working rotor of blower fan.Accurate instrument for wind measurement is transferred to the software of computer with testing signal, and the motor of rear driving yaw system and gear-box make blower fan reduce as much as possible the wind energy loss by analysis, increase the effective time.
Yaw system is comprised of slewing bearing, yaw brake disc, brake callipers and several motor-driven gear drives.Driftage brake part generally is comprised of two-part in general yaw system, a motor electromagnetic break that is mounted in the drive motor rear end, and a part is mounted near the hydraulic yawing the driftage bearing.When not going off course, brake callipers and brake disc are in " locking " state, and brake callipers is in half releasing state during driftage, and brake callipers is in full releasing state during automatic cable-releasing.Usually the driftage time of default is generally (10-15) minute, relies on the brake block friction that is installed on the brake callipers to produce braking effect between brake callipers and the brake disc; Operation very easily causes the excessive wear of brake block for a long time; Especially the brake block when brake callipers weares and teares totally, and does not in time change, and causes brake callipers body and brake disc direct friction, will cause serious harm to brake disc, the puzzlement that the normal operation and maintenance cost of fan brings.
Brake disc of the prior art is generally integrated type, and manufacturing is simple, and is easy for installation; But because the projected life of Megawatt fan is longer, brake block with the brake disc friction process in, the wear extent of brake disc builds up, if things go on like this, will when acquiring a certain degree, the brake disc wear extent carry out the replacing of brake disc, whole unit need to be hung oneself from blower fan, will cause and be maintained as greatly the discord workload.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and the wind driven generator yaw brake disc of a kind of structural design advantages of simple, easy accessibility is provided.
Technical problem to be solved in the utility model is to realize by following technological scheme.The utility model is a kind of wind-powered electricity generation unit yaw brake disc, and be characterized in: this brake disc comprises retaining ring, disassembling braking dish and fastening piece; Described retaining ring is fixedly connected with the cabin seat of blower fan, and the disassembling braking dish is connected with retaining ring by fastening piece.
In the wind-powered electricity generation unit yaw brake disc technological scheme described in the utility model, further preferred technological scheme or technical characteristics are:
1. described disassembling braking dish is comprised of some split type brake disc pieces.When brake disc and fixed tray are installed, but integral installation also can split typely be installed; Especially when changing brake disc, partial installation can greatly improve working efficiency and reduces the blower fan maintenance cost.
2. described disassembling braking dish is comprised of the split type brake disc piece of 2-4 piece.
3. connection is inlayed in the concavo-convex cooperation in joint of adjacent split type brake disc piece, for example the connection mouth of " Z " shape structure.Can guarantee like this to be connected firmly and the levelness of card.
4. described fastening piece is sunk screw.The fastening piece effect is that retaining ring and brake disc are fixed together, and usually selects sunk screw, guarantees not take narrow and small brake space.
5. retaining ring is provided with bolt hole, uses high-strength bolt by screw hole retaining ring to be installed on the cabin seat of blower fan.
Compared with prior art, the utility model reasonable in design is used easy installation and removal, greatly reduces the maintenance cost that the on-the-spot replacing of wind-powered electricity generation brake disc brings, and guarantees the normal operation of blower fan, makes maintenance more convenient.
