Description
Technical field
The invention belongs to wind driven generator yaw brake system field, be specifically related to a kind of mechanical brake.
Background technology
Brake fluid system is arranged on a firm banking, and its relative brake dish is static, and brake disc diameter is general
At more than 2000mm, thickness is 30mm, and upper and lower two parallel surface unevenness, at more than 2mm, can produce brake disc and axially jump during rotation
Dynamic, when beating occurs in disc rotation, liquid braking device upper and lower pincers casket stress occurs the most unbalanced thus passes to piston
Oil cylinder, finally results in piston heavy wear and causes oil cylinder leakage of oil, contaminates causing serious greasy dirt in cabin.Liquid braking device is because returning
Rotating shaft is held and brake disc horizontal plane is beated will cause the bolt strained complexity of brake bolt fracture, piston detonation occur and stop
The phenomenon of machine, and other components in cabin are caused corresponding damage.
Summary of the invention
It is an object of the invention to provide a kind of can eliminate because of the axial runout of brake disc brakes is brought with
The mechanical yaw brake of upper adverse effect.
For realizing object above, the invention discloses a kind of mechanical yaw brake, be arranged on wind power generating set
On mainframe, including upper pincers casket and lower pincers casket, described upper pincers casket also wraps together with being bolted to connection with described lower pincers casket
Include through described upper pincers casket and the movable latch of described lower pincers casket；It is also equipped with, in described upper pincers casket, the pressure that least one set matches
Tight pin, withstanding tight block and disc spring, the two ends of described disc spring are supported described compression respectively and are sold and described withstanding tight block；At described compression pin
It is arranged over locking nut and regulation bolt；In the upper end of described withstanding tight block, described compression pin and the center of described locking nut
Being provided with mating holes, be provided with mark rod in described mating holes, one end of described mark rod is fixing with described withstanding tight block to be connected, another
End is emerging in outside described locking nut, and described mark rod is provided with visual graticule at locking nut.
Wherein, described visual graticule has two, and one is red, and one is green.
Wherein, on described, casket is clamped at described withstanding tight block near the surface of described lower pincers casket and/or described lower pincers casket
Surface is embedded with friction plate.
Wherein, described friction plate is thermostability engineering plastic or senior wearing composite material friction plate, therefore described in rub
Pad does not contains iron, rubs off the powder got off and motor will not be produced impact.
Beneficial effects of the present invention: simple in construction, it is not necessary to hydraulic oil, fundamentally solves Leakage；Only need to pass through
Mark rod indicates and makes regular check on pretightning force, and easy to maintenance, service life is long.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of mechanical yaw brake, including upper pincers casket 1 and lower pincers casket 10, institute
State upper and lower pincers casket to be fixed together by 5 M24 × 160 bolts 3；Also include through described upper pincers casket and described lower pincers
The movable latch 2 of casket；Two groups of compression pins 7 matched, withstanding tight block 9 and disc spring 8, described disc spring it is also equipped with in described upper pincers casket
The two ends of 8 support described compression pin 7 and described withstanding tight block 9 respectively；Being arranged over for regulating described pressure at described compression pin 7
The locking nut 4 of tight pin 7 thrust and regulation bolt 5；In the upper end of described withstanding tight block 9, described compression pin 7 and described locking screw
The center of female 4 is provided with mating holes, is provided with mark rod 6, one end of described mark rod 6 and described withstanding tight block 9 in described mating holes
Fixing connection, the other end is emerging in outside described locking nut 4, and described mark rod 6 is provided with red green two mesh at locking nut 4
Sighting target line, green visually graticule 12 is positioned at above red visually graticule 13.When the most green visual graticule 12 reveals, table
Show safety；When hot Semu sighting target line 13 reveals, represent and need pretension disc spring pressure again.
On described, the table of casket 1 is clamped near the surface of described lower pincers casket 10 and described lower pincers casket 10 at described withstanding tight block 9
Face is all embedded with friction plate 11, and described friction plate 11 is thermostability engineering plastic or senior wearing composite material friction plate, because of
Described friction plate does not contains iron, so motor will not be produced impact because rubbing off the powder got off.
Applying according to reality, withstanding tight block 9 could be arranged to integrated ladder shaft-like, it is also possible to for detachable maintaining side
Just, withstanding tight block 9 is set to two pieces of separate form up and down of tight fit connection, the concrete structure work of withstanding tight block 9 is not had at this
Body limits.
Described mechanical yaw brake is arranged on the mainframe of wind power generating set, and during installation, described activity is inserted
Pin 2 sequentially passes through described upper pincers casket 1, described mainframe and described lower pincers casket 10 and this mechanical yaw brake is arranged on solid
On fixed rack, during work, brake disc is clamped by upper and lower friction plate by the clamping force set, when disc rotation, and friction plate
Brake disc is produced a kind of frictional force (brake force) in opposite direction with disc rotation, and brake is then by movable latch 2
Along with brake disc axial runout along bolt axle to wander up and down.Now brake does not changes with the clamping duty of brake disc
Becoming, the parallel surface unevenness simultaneously produced by brake disc all eliminates in end-play, and it is any unfavorable not bring brake unit
Impact, this kind of mechanism's sheerly mechanical type non-hydraulic system, on the premise of ensureing performance, thoroughly avoid brake fluid system
The phenomenons such as hydraulic oil leakage, bolt fracture, piston detonation and shutdown, and substantially reduce the number maintenance downtime.
Above a kind of mechanical yaw brake provided by the present invention is described in detail, herein to the present invention
Principle and embodiment be set forth, the explanation of above example is only intended to help to understand method and the core thereof of the present invention
Thought is thought；Simultaneously for one of ordinary skill in the art, according to the thought of the present invention, at detailed description of the invention and application model
Placing and all will change, in sum, this specification content should not be construed as limitation of the present invention.
