Abstract
The utility model discloses a kind of device for the finishing of wind driven generator yaw bearing face, comprise the emery wheel body, connecting rod, push rod and the stationary cylinder that connect successively from the bottom up, the bottom surface of stationary cylinder is provided with the gathering sill of indent, the upper end of push rod is connected in gathering sill, the two ends of connecting rod respectively with push rod and emery wheel body by there being the hinge of lock function, stationary cylinder is connected with the dial gauge for recording yaw axis socket end surface jitter.The cabin of stationary cylinder and wind-driven generator is bolted fixing.The radial and axial movement of emery wheel body along driftage bearing can be controlled by connecting rod and push rod, thus control the upper-lower position of emery wheel body and grinding depth is repaired driftage bearing face, ensure that it reaches designing requirement by the flatness of centimeter check finishing rear end face and roughness.Be conducive to ensureing that brakes has stable pressure, wind power generating set is run reliably and with long-term.Driftage bearing face is repaired more convenient, without the need to dismantling cabin, simply easy to maintenance.
Description
Technical field
The utility model relates to a kind of wheel dresser, especially relates to a kind of device for the finishing of wind driven generator yaw bearing face.
Background technology
MW class wind turbine all adopts active yawing system, provides braking moment by off-course brake, guarantees that blower fan is accurate in power generation process, steady to wind.In During yaw, off-course brake provides yaw damping, and therefore off-course brake friction plate needs after using a period of time to change.Sometimes, field maintenance person does not change in time, and cause friction plate steel back directly to wear and tear with driftage bearing face, bearing face flatness and roughness are difficult to reach requirement.Once bearing face damages, need to repair it, otherwise friction disc wear can be caused to aggravate, make yaw system cannot obtain enough yaw dampings, make blower fan there is potential safety hazard.But, when not dismantling cabin, repair more difficult to driftage bearing face.
Utility model content
The purpose of this utility model is to provide a kind of without the need to dismantling the device that cabin just can easily be repaired driftage bearing face.
The utility model
the disclosed this device for the finishing of wind driven generator yaw bearing face, comprise the emery wheel body, connecting rod, push rod and the stationary cylinder that connect successively from the bottom up, the bottom surface of stationary cylinder is provided with the gathering sill of indent, the upper end of push rod is connected in gathering sill, the two ends of connecting rod respectively with push rod and emery wheel body by there being the hinge of lock function, stationary cylinder is connected with the dial gauge for recording yaw axis socket end surface jitter.The cabin of stationary cylinder and wind-driven generator is bolted fixing.
Described emery wheel body adopts emery wheel reconditioning head.
Described bearing pin adopts bulb locking pin.
The end face of described stationary cylinder has some through holes along its thickness direction, and there is screw thread the upper end of through hole, and the measuring staff of described dial gauge is fixed by locking nut through after one of them through hole.
Gathering sill on described stationary cylinder bottom surface and the arc protective cover be provided with between dial gauge measuring staff for preventing the chip damage dial gauge produced during described emery wheel body running.
The utility model is removably connected by the cabin of stationary cylinder and wind-driven generator, the radial and axial movement of emery wheel body along driftage bearing can be controlled by connecting rod and push rod, thus control the upper-lower position of emery wheel body and the end face of grinding depth to driftage bearing is repaired, ensure that it meets designing requirement by the flatness of centimeter check finishing rear end face and roughness.
Repaired the wearing and tearing end face of driftage bearing by this device in good time, to ensure that brakes has stable pressure, be conducive to wind power generating set and run reliably and with long-term.When carrying out the finishing of driftage bearing face, without the need to dismantling cabin, simply easy to maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
Detailed description of the invention
As shown in Figure 1, disclosed in the utility model, this device for the finishing of wind driven generator yaw bearing face, comprises emery wheel body 1, connecting rod 2, push rod 3, stationary cylinder 5, dial gauge 4.Emery wheel body 1 adopts emery wheel reconditioning head.The bottom surface of stationary cylinder 5 is provided with the gathering sill 51 of indent, the upper end of push rod 3 is connected in gathering sill 51, the two ends of connecting rod 2 are hinged by bulb locking pin 6 respectively and between push rod 3 and emery wheel body 1, the end face of stationary cylinder 5 is provided with some through holes 52 along its thickness direction, there is screw thread the upper end of through hole 52, the measuring staff of dial gauge 4 is fixed by locking nut 7 through after one of them through hole 52, to record the jitter values of driftage bearing face.The object that arranges of some through holes 52 is that when this device is repaired for different driftage bearing faces, dial gauge 4 can select suitable position to fix.
In order to prevent the chip damage dial gauge 4 produced during emery wheel body 1 grinding driftage bearing face, between the gathering sill 51 on stationary cylinder 5 bottom surface and the measuring staff of dial gauge 4, arc protective cover 8 is set.
During installation, dismantle the off-course brake that is positioned at cabin, on stationary cylinder 5, process corresponding screwed hole 53 according to off-course brake to the bolt hole position that cabin connects, by off-course brake installing hole and screwed hole 53, stationary cylinder 5 and cabin are fastened by bolts.Then dial gauge 4 is placed in the through hole 52 of correct position, fixing after regulating its upper-lower position by locking nut 7; The position of regulating pushing rod 4 in gathering sill 51, is made connecting rod 2 and emery wheel body 1 be positioned at suitable driftage bearing radial position, is controlled upper-lower position and the grinding depth of emery wheel body 1 by connecting rod 2.
When driftage bearing face is repaired, start manually driftage, make emery wheel body 1 carry out grinding work, move radially push rod 3 meanwhile along driftage bearing, and record the jitter values of dial gauge 4 at driftage bearing face, until centimeter check to end face run-out value meets design requirement.
