Description
Technical field
The invention belongs to wind driven generator yaw brake system field, be specifically related to a kind of mechanical brake.
Background technique
Hydraulic braking sytem is arranged on a fixed base, its relative brake disc is static, brake disc diameter is generally more than 2000mm, thickness is 30mm, upper and lower two parallel surface Roughness, more than 2mm, can produce brake disc axial runout during rotation, thereby rotate the serious unbalanced piston oil-cylinder that passes to of the stressed appearance of the upper and lower pincers casket of hydraulic brake while occurring beating when brake disc, finally cause piston heavy wear to cause oil cylinder leakage of oil, to causing serious oil pollution in cabin.Hydraulic brake is beated and will be caused the bolt strained complexity of break to occur the phenomenon of bolt fracture, piston detonation and shutdown because of floating bearing and brake disc horizontal plane, and other members in cabin are caused to corresponding damage.
Summary of the invention
The object of the present invention is to provide the mechanical type off-course brake of the above adverse effect that a kind of axial runout that can eliminate because of brake disc brings braking system.
For realizing above object, the invention discloses a kind of mechanical type off-course brake, be arranged on the mainframe of wind power generating set, comprise pincers casket and lower pincers casket, described upper pincers casket also comprises the movable latch through described upper pincers casket and described lower pincers casket together with being bolted to connection with described lower pincers casket; At least one group of the compression pin matching, withstanding tight block and dish spring are also installed in described upper pincers casket, and described compression pin and described withstanding tight block are supported respectively in the two ends of described dish spring; Above described compression pin, be provided with locking nut and adjusting bolt; Center at the upper end of described withstanding tight block, described compression pin and described locking nut is provided with matching hole, in described matching hole, mark rod is installed, one end of described mark rod is fixedly connected with described withstanding tight block, the other end is emerging in outside described locking nut, and described mark rod is provided with visual graticule near locking nut place.
Wherein, described visual graticule has two, and one is red, and one is green.
Wherein, described withstanding tight block near described lower pincers casket surface and/or described lower pincers casket near the surface of clamping casket on described, be embedded with friction plate.
Therefore wherein, described friction plate is thermostability engineering plastic or senior wearing composite material friction plate, and described friction plate iron containing substrates material not, rubs off the powder getting off and can not exert an influence to motor.
Beneficial effect of the present invention: simple in structure, without hydraulic oil, fundamentally solved Leakage; Only need indicate and make regular check on pretightening force by mark rod, easy to maintenance, long service life.

Embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of mechanical type off-course brake, comprises pincers casket 1 and lower pincers casket 10, and described upper and lower pincers casket is fixed together by 5 M24 * 160 bolts 3; Also comprise the movable latch 2 through described upper pincers casket and described lower pincers casket; Two groups of the compression pins 7 that match, withstanding tight block 9 and dish springs 8 are also installed in described upper pincers casket, and described compression pin 7 and described withstanding tight block 9 are supported respectively in the two ends of described dish spring 8; Above described compression pin 7, be provided with for regulating described compression to sell locking nut 4 and the adjusting bolt 5 of 7 impacting forces; Center at the upper end of described withstanding tight block 9, described compression pin 7 and described locking nut 4 is provided with matching hole, mark rod 6 is installed in described matching hole, one end of described mark rod 6 is fixedly connected with described withstanding tight block 9, the other end is emerging in outside described locking nut 4, described mark rod 6 is provided with red green two visual graticules near locking nut 4 places, and green visual graticule 12 is positioned at above red visual graticule 13.When only having green visual graticule 12 to reveal, represent safety; When hot Semu sighting target line 13 reveals, represent to need pretension dish spring pressure again.
At described withstanding tight block 9, near surface and the described lower pincers casket 10 of described lower pincers casket 10, near the surface of clamping casket 1 on described, be all embedded with friction plate 11, described friction plate 11 is thermostability engineering plastic or senior wearing composite material friction plate, because of described friction plate iron containing substrates material not, so can not exert an influence to motor because rubbing off the powder getting off.
According to practical application, withstanding tight block 9 can be set to integrated multidiameter shaft shape, also can be convenient for detachable maintaining, withstanding tight block 9 is set to two separate form up and down of tight fit connection, and at this, the concrete structure of withstanding tight block 9 is not done to concrete restriction.
Described mechanical type off-course brake is arranged on the mainframe of wind power generating set, during installation, described movable latch 2 is arranged on this mechanical type off-course brake on fixed support through described upper pincers casket 1, described mainframe and described lower pincers casket 10 successively, during work, upper and lower friction plate clamps brake disc by the clamping force of setting, when brake disc rotates, friction plate produces frictional force (braking force) a kind of and brake disc direction of rotation to brake disc, and break moves about along bolt axle along with brake disc axial runout up and down by movable latch 2.Now the clamping working state of break and brake disc does not change; the parallel surface Roughness being produced by brake disc is all eliminated in axial internal clearance simultaneously; braking device is not brought to any adverse effect; Ci Zhong mechanism is mechanical type non-hydraulic system sheerly; under the prerequisite of guaranteed performance, thoroughly avoid the phenomenons such as hydraulic oil leakage, bolt fracture, piston detonation and shutdown of hydraulic braking sytem, and reduced in a large number maintenance downtime.
Above a kind of mechanical type off-course brake provided by the present invention is described in detail, herein principle of the present invention and mode of execution is set forth, above embodiment's explanation is just for helping to understand method of the present invention and core concept thereof; , for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention meanwhile.
