Abstract
The utility model discloses a novel friction plate for a yawing brake of a wind turbine generator, which comprises a steel backing and a friction block, wherein a chip room is arranged on the friction block, the projecting plane of the chip room is V-shaped, and the direction of an opening is consistent with the centrifugal direction of rotation of a yawing brake disk of the wind turbine generator. The novel friction plate has the advantages that as the projecting plane of the chip room is V-shaped, the novel friction plate is conductive to enhancing the capability of accommodating chips of the cuttings chute; simultaneously, the direction of the opening is consistent with the centrifugal direction of the rotation of the yawing brake disk of the wind turbine generator, thereby being easier to guide the discharge of the chips, and leading the discharge of the chips to be easier under the action of centrifugal force. Furthermore, as the friction block is trapezoidal, the novel friction plate is conductive to discharging the chips produced on two sides of the friction block.
Description
Technical field
The utility model relates to a kind of braking device, especially relates to the novel friction plate of a kind of wind driven generator yaw break.
Background technique
The structure of existing friction plate is rectangular profile as shown in Figure 3 and Figure 4, comprises steel backing 21 and brake pad 22, has the twice straight trough as groove 23 on brake pad 22.
This straight trough structure of existing friction plate groove is easy to generate chip removal difficulty and the bigger phenomenon of noise, and owing to abrasive dust can't in time be discharged, be deposited between friction plate and the brake disc, easily generation rolls hardening phenomenon once more under the interaction extruding of friction plate and brake disc, form extremely hard lump and high point, make the excessive wear herein of brake pad and brake disc, cutting, thereby produce annular groove, the influence driftage operates steadily and send sharp-pointed noise.
The model utility content
The utility model has overcome shortcoming of the prior art, provide a kind of wind driven generator yaw break novel friction plate, in use obviously improved abrasive dust and discharged not smooth problem, the bits that rub that cause because of the abrasive dust eliminating is difficult are piled into piece and are caused the excessive problem of sharp-pointed noise also to obtain solution effectively.
The technical solution of the utility model is: the novel friction plate of a kind of wind driven generator yaw break, comprise: steel backing and brake pad, have groove on brake pad, the projection plane of described groove is a V-arrangement, and opening direction is consistent with the centrifugal direction that the wind driven generator yaw brake disc rotates.
Being shaped as of described brake pad is trapezoidal, is shorter than another base towards the base of groove V-arrangement opening direction.
Compared with prior art, the utility model has the advantages that:, help strengthening the appearance bits ability of groove like this because the projection plane of groove is a V-arrangement; Simultaneously, because opening direction is consistent with the centrifugal direction that the wind driven generator yaw brake disc rotates, therefore the discharge of easier guiding abrasive dust makes abrasive dust chip removal under action of centrifugal force be more prone to.And, because being shaped as of brake pad is trapezoidal, also help the discharge of the abrasive dust of brake pad both sides generation.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a plan view of the present utility model;
Fig. 3 is the front view of existing wearing piece;
Fig. 4 is the plan view of existing wearing piece.
Embodiment
The novel friction plate of a kind of wind driven generator yaw break as depicted in figs. 1 and 2, comprising: steel backing 1 and brake pad 2 have groove 3 on brake pad 2.
The projection plane of described groove is complete V-arrangement, and opening direction is consistent with the centrifugal direction that the wind driven generator yaw brake disc rotates.For the ease of the discharge of the abrasive dust of brake pad both sides of the edge, being shaped as of described brake pad is trapezoidal, and two sides of brake pad are trapezoidal waist, are shorter than another base towards the base of groove V-arrangement opening direction.
Claims (2)
1. novel friction plate of wind driven generator yaw break, comprise: steel backing and brake pad, have groove on brake pad, it is characterized in that: the projection plane of described groove is a V-arrangement, and opening direction is consistent with the centrifugal direction that the wind driven generator yaw brake disc rotates.
2. the novel friction plate of wind driven generator yaw break according to claim 1, it is characterized in that: being shaped as of described brake pad is trapezoidal, is shorter than another base towards the base of groove V-arrangement opening direction.
