Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the attached drawing in the present invention, to this Technical solution in invention is clearly and completely described.
Embodiment one, as shown in Figure 1 to Figure 2, a kind of yaw brake disc of wind power generating set, including brake disc pedestal 1 With brake actuator 2,1 upper surface of brake disc pedestal is fixedly connected with upper end brake disc, and 1 lower surface of brake disc pedestal is fixedly connected There is a lower end brake disc, be provided with tower flanges 3 below the brake disc of lower end, bolt is flexibly connected by screw thread below tower flanges 3 4 one end, the other end of bolt 4 sequentially pass through tower flanges 3, lower end brake disc, brake disc pedestal 1 and upper end brake disc and spiral shell Line is connected with nut 6;Brake actuator 2 is fixedly mounted on 7 lower surface of generating set bed board, the clamping end point of brake actuator 2 It is not in contact with upper end brake disc and lower end brake disc.
Thus when the upper end brake disc or lower end brake disc that are in contact with brake actuator 2 are worn, it can be according to brake The abrasion condition selection disassembly upper end brake disc or lower end brake disc of hull, in disassembly, the effect being connected through a screw thread will Bolt 4 removes, that is, may be selected to replace with end brake disc or lower end brake disc, to save the replacement cost of brake disc.
Embodiment two, based on the further improvement of embodiment one, upper end brake disc includes upper end inner ring brake disc 8 and upper end Outer ring brake disc 9, upper end inner ring brake disc 8 and upper end outer ring brake disc 9 are arranged concentrically, and lower end brake disc includes that lower end inner ring is stopped Hull 10 and lower end outer ring brake disc 11, lower end inner ring brake disc 10 and lower end outer ring brake disc 11 are arranged concentrically;Fixing bolt 4 Sequentially pass through tower flanges 3, lower end outer ring brake disc 11, brake disc pedestal 1 and upper end outer ring brake disc 9 and with 6 spiral shell of nut Line connection, the clamping end of brake actuator 2 is in contact with upper end inner ring brake disc 8 and lower end inner ring brake disc 10 respectively.Upper end Inner ring brake disc 8 and 10 surface of lower end inner ring brake disc offer the first groove 12 and the second groove 13, the first groove 12 respectively Inside offer threaded hole, threaded hole runs through upper end inner ring brake disc 8, brake disc pedestal 1 and lower end inner ring brake disc 10, and with the Two grooves 13 are connected, and one end of installation fastening bolt 14 in the first groove 12,14 other end of fastening bolt passes through threaded hole, and It is threadedly coupled with the fastening nut 15 in the second groove 13.
It since the outer ring of brake disc is not in contact with brake actuator 2, therefore will not wear, therefore by by upper end Brake disc is divided into upper end inner ring brake disc 8 and upper end outer ring brake disc 9, and lower end brake disc is divided into 10 He of lower end inner ring brake disc Lower end outer ring brake disc 11, to by removing fastening bolt 14, that is, may be selected to replace with end when brake disc is worn Inner ring brake disc 8 or lower end inner ring brake disc 10 do not need replacement upper end outer ring brake disc 9 and lower end outer ring brake disc 11, To reach saving cost, simplify the purpose of maintenance;It is recessed by the way that fastening bolt 14 and fastening nut 15 are separately mounted to first In slot 12 and the second groove 13, so as to prevent fastening bolt 14 from impacting to brake actuator 2.
Embodiment three, based on the further improvement of embodiment two, upper end inner ring brake disc 8 and lower end inner ring brake disc 10 are set It is equipped with multiple, and uniform annular is distributed in the upper and lower surfaces of brake disc pedestal 1 respectively.By by upper end inner ring brake disc 8 and lower end inner ring brake disc 10 use segment design, can be targetedly to corresponding abrading section thus when wearing It is individually replaced, to greatly save replacement cost;And segment design is also convenient for the moving of component, upper tower and tears open Work is filled, the hoisting cost of component has been saved, the requirement for installation space reduces, and realizes convenient for operation.
Example IV, as shown in Fig. 2, the further improvement based on embodiment three, two neighboring 8 He of upper end inner ring brake disc The port that lower end inner ring brake disc 10 is in contact is S-type.To make brake actuator 2 pass through two neighboring inner ring brake disc When, can smooth transition, to can also achieve the effect that noise reduction;And two neighboring inner ring brake disc passes through S type interface Transition can be realized the self-locking function between inner ring brake disc, brake so as to avoid upper end inner ring brake disc 8 and lower end inner ring Hidden danger of the disk 10 to inner ring off-centring.
Embodiment five, as shown in figure 3, the further improvement based on embodiment three, upper end inner ring brake disc 8 and lower end inner ring 10 surface of brake disc offers crumb loading slot 16.There are four crumb loading slot 16 in the present embodiment is set, and it is evenly distributed in upper end 10 surface of ring brake disc 8 and lower end inner ring brake disc, so that the scraping by brake actuator 2 and the notch of crumb loading slot 16 is made With, can to upper end inner ring brake disc 8 because friction generate abrasive dust be collected cleaning;And then reduces foreign matter and brake to inner ring The influence of disk, then reduces the generation of yaw oscillation and noise, while also enhancing frictional behaviour, increases inner ring brake disc Service life.
Embodiment six, based on the further improvement of embodiment three, upper end outer ring brake disc 9 and lower end outer ring brake disc 11 are equal It is in unitary design with brake disc pedestal 1.So as to greatly improve upper end outer ring brake disc 9 and lower end outer ring brake disc 11 Stability and fastness.
Embodiment seven, based on the further improvement of embodiment three, outside upper end inner ring brake disc 8 and lower end inner ring brake disc 10 Surface is fixedly connected to quenching layer.To make upper end inner ring brake disc 8 and lower end inner ring brake disc 10 that there is high rigidity and height The surface of wearability, and then can further improve the service life of upper end inner ring brake disc 8 and lower end inner ring brake disc 10.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations;Although with reference to the foregoing embodiments Invention is explained in detail, those skilled in the art should understand that: it still can be to aforementioned each implementation Technical solution documented by example is modified or equivalent replacement of some of the technical features;And these modification or Replacement, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
