Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind power generation device that generates power by a main shaft driven generator that is rotated by a wind, and in particular relates to a yaw (YAW) rotary bearing structure of a wind power generation device. . [Prior Art] A "wind power generation device is a device in which a rotor head having a wind turbine blade is rotated by a wind force" to increase power by a speed increaser to drive a generator to generate electricity. In addition, the rotor head with the wind turbine wing is connected to the speed increaser and the generator in the engine room provided above the tower (pillar), so that the orientation of the rotor head matches the constantly changing wind direction. A tilting rotation device that rotates on the tower. Fig. 18 is a view showing an example of the configuration of the prior yaw rotation device. The yaw rotation device 10 shown in Fig. 18 is fixed between the inner rim 2a of the base member (cabin platen) 11 fixed to the nacelle side on the tower, and the outer wheel 12b fixed to the stationary tower side. A rolling bearing 12 in which a ball bearing nc 〇 or the like is interposed is used. That is, in the illustrated yaw rotation device 1 滚动, the rolling bearing 12 is employed as the yaw rotary bearing rolling bearing. The swaying rotation device 10 in this case includes a fixed gear 13 formed on the outer circumference of the outer ring 12b, and a drive gear 15 that is rotated by a biasing motor 14 fixed to the nacelle side. Further, since the drive gear 15 is meshed with the fixed gear 13, the drive gear 15 is rotationally moved around the fixed gear 13 in accordance with the rotational direction of the yaw motor ,, so that the base member u and the yaw motor 14 are driven The gear 15-body rotates in a clockwise or counterclockwise direction with respect to the stationary tower 141085.doc 201100633. In the frame, the symbol 16 is a brake disc, a 17-series brake pad, and an 18-series brake tray. In the wind power generator, the above-mentioned yaw rotation axis is present (4) β-axis. (For example, refer to Patent Document 1) The sliding bearing ′ in this case mainly receives a moment load on a plane αρ formed on the upper surface and the lower surface of the upper portion of the tower, and the sliding bearing member ' in contact with the flat portion is fixed to the nacelle side. Further, the flat portion in this case is formed only on one of the inner side or the outer side of the tower. [Patent Document] Japanese Patent Application Publication No. 2003-518594. SUMMARY OF THE INVENTION In the first year, the wind power generation device has a tendency to increase in size, and the following problems have been pointed out with the increase in size. That is, the enlargement of the wind power generation device inevitably leads to an increase in the size of the bearings connecting the tower and the nacelle. Therefore, in particular, in the case where a rolling bearing is used as the rolling bearing, the bearing diameter or the ball diameter of the bearing needs to be specially customized, so that the cost of the bearing increases. In addition, it is difficult to divide and transport the bearing itself by using the rolling bearing. Therefore, with the increase in the size of the bearing, there is a problem that the ground transportation cost is exceeded. The other side Φ ′ will cause alignment (biased wear) when the swaying bearing is a sliding bearing. In other words, since the wind power generator acts on the wind power generator to bias the wind power generator in the direction of the wind power generation device, the previous yaw rotation bearing using the sliding bearing may have partial wear due to the planar support. 'H' will produce a partial wear, which will cause the tower 141085.doc 201100633 to loosen the top of the roof and there is a problem that the top of the tower is unstable. Further, as the size of the wind power generation device increases, so does the problem of ease of assembly on site. In other words, as the tower becomes higher, the number of cranes generated by the increase in the size of the cranes used for the increase in the size of the cranes will increase. Further, in the state in which the crane is hoisted in the nacelle, since the tower side and the nacelle side are connected by bearings, it takes time to increase the construction cost. In addition, the bolts that are combined with the yaw bearing and the upper part of the tower, and the bolts that connect the yaw 旋转 rotary bearing to the nacelle are placed in the vertical direction to take up the tensile or compressive load due to the aforementioned direction of the tilting direction. In addition, the number of bolts is determined based on the strength of the bolt, and the number of bolts (arrangement) determines the upper portion of the tower. Therefore, if the wind power generator is increased in size, the size of the table is based on the upper portion of the tower. It is determined by the path, so as the diameter of the upper part of the tower increases, the weight of the cabin platen will also increase. Under such a background, it is desired to solve the problems associated with the bearing of the tower and the nacelle caused by the increase in the size of the wind power generator, and the increase in the size of the wind power generator is easy. The present invention has been completed in the foregoing case, and the object of the present invention is to provide a wind power generation device which solves many problems caused by the connection of the bearings of the tower and the nacelle, and which is easy to carry out.

Since the length (H) of the cymbal is set to be equal to the horizontal direction of the sliding bearing material and is twice as large as v, it can reliably withstand the tilting direction moment load of the tower which is greatly increased compared with its own weight. The wind turbine generator according to claim 2, wherein the nacelle provided in the tower f is rotatably supported by a swaying bearing that receives a moment load in a tilting direction through a plane portion above and below the main line, in the tower At least one of the inner circumferential side and the outer circumferential side is provided with a sliding bearing material of the slanting sliding bearing, and the sliding bearing material is fixed to the tower side. According to the wind power generation device of claim 2, the nacelle provided on the tower is rotatably supported by the slanting sliding bearing that is subjected to the tilting direction moment load in the plane portion above and below the main line, and the sliding bearing material is It is fixed to the tower side, so a sliding bearing structure with a separable structure can be used. In particular, since at least one of the inner circumferential side and the outer circumferential side of the tower is provided with a sliding bearing material of a slanting sliding bearing, and the sliding bearing material is fixed to the tower side, it can be assembled from the inner side of the tower to wind power generation. The device's biased sliding bearing provides good maintainability. The wind power generation device of the third aspect, wherein the nacelle provided on the tower is rotatably subjected to a tilting sliding bearing with a tilting direction torque of 141085.doc 201100633 through a plane portion above the main system The sliding bearing material of the above-described yaw bearing is provided on both the inner circumferential side and the outer circumferential side of the tower, and the sliding bearing material is fixed to the nacelle side.

The moving bearing material is fixed to the nacelle side, so a sliding bearing structure with a separable structure can be used to reduce the diameter of the upper portion of the tower. That is, if the upper part of the tower is T-shaped, the sliding bearing material is placed on both the inner circumference side and the outer m shape of the tower, and the upper part of the tower is connected with the biasing sliding bearing or the bolt of the nacelle and the sliding sliding bearing. The wall surface of the tower 2 can be clamped and arranged symmetrically on the inner circumferential side and the outer circumferential side of the tower. Therefore, the load acting on each bolt can be reduced. Therefore, the number of bolts around the inner circumference side and the outer circumference side of the tower can be reduced to reduce the diameter of the upper portion of the tower.

"Support, by this, a good bearing for the connecting tower and the nacelle can be obtained. The wind power generating device according to the present invention, which is accompanied by the large-scale, has a slidable sliding bearing with a detachable structure, 141085.doc 201100633 The problem of the large-scale wind power generator is easy to carry out by the problems of the rotary bearing. [Embodiment] An embodiment of the wind power S electric device according to the present invention will be described with reference to Figs. 1 to 4 under λ. The wind power generation device 具有 has a tower (also referred to as a "pillar" 2 erected on a foundation b; a nacelle 3 disposed at an upper end of the tower 2; supported to be rotatable about a substantially horizontal transverse direction The axis rotation is set on the rotor head 4 of the machine. A plurality of (for example, three) windmill % rotor blades 5 are radially mounted around the axis of rotation of the rotor head 4. Thereby, the wind force that hits the wind turbine rotating blade 5 from the direction of the winding of the rotor head 4 is converted into the power that rotates the rotor head 4 about the rotation axis. <First Embodiment> The wind power generator 丨 includes a yaw rotation device 20 that robs the machine provided at the upper end portion of the tower 2 in a three-way rotation so that the direction of the rotor head 4 is adjusted to match the wind direction. The yaw rotation device 20, & rotatably supports the nacelle 3' provided at the upper end portion of the tower 2, and the side portion having the main upper and lower directions is subjected to the tilting direction moment load of the tower 2 (hereinafter referred to as " The torque load ") is biased by the sliding bearing 30. As shown in FIG. 2, the yaw rotation device 20 of the above-described case includes a fixed gear 21 formed on the outer peripheral surface of the upper end portion of the tower 2, and a base member (cabin platen) fixed to the nacelle side. The driving of the yaw motor 23 of 22 is 141085.doc 201100633 gear 24. Further, by engaging the drive gear 24 with the fixed gear 21, the drive gear 24 is rotationally moved around the fixed gear η in accordance with the rotational direction of the yaw motor 23, so that the base member 22 and the yaw motor 23 are opposed to each other via the yaw The tower 2, which is supported by the sliding bearing 3G, rotates clockwise or counterclockwise. The swaying sliding bearing 3〇 of the above-described yaw rotating device 2〇, as shown in FIG. 2 and FIGS. 2A and 2B, is configured such that a fixed cymbal 31 formed at an upper end portion of the tower 2 and suspended from the pedestal Between the rotating portions 32 on the lower surface of the member 22, a vertical sliding bearing member (hereinafter referred to as "vertical bearing member") 33 that is opened in the vertical direction is disposed as a main sliding bearing member. Further, in the configuration example of the figure, a horizontal sliding bearing member (hereinafter referred to as "horizontal bearing member") 34 is provided between the upper end portion of the tower 2 and the lower surface of the base member ,, thereby forming a support vertical direction and The composition of two sides in the horizontal direction. The fixed portion 31 is fixed to the inner periphery of the cylindrical member at the upper end of the tower 2, and the fixed gear 21 is formed on the outer peripheral surface of the cylindrical member 2a. The cylindrical member 2a is not only finished to the surface where the inner peripheral surface is in contact with the sliding surface of the vertical bearing member 33, but also forms the fixed gear 21 on the outer peripheral surface, so that it is usually independent of the member of the lower tower body 2b. - The red rotating portion 32 is a member having a substantially L-shaped cross section fixed to the lower surface of the base member 22, and the circumferential direction of the fixing portion 31 is divided into plural and arranged at equal intervals. In the configuration example of the figure P, as shown in FIG. 2B, the twelve rotating portions 32 are arranged at a pitch of 30 degrees, and the vertical bearing members 33 in the vertical direction and the horizontal bearing members 34 in the left-right direction are fixed to the respective rotating portions 32. . 141085.doc 201100633 As described above, the wind turbine generator 1 of the present embodiment is provided in the nacelle 3 of the upper portion of the tower 2, and is mainly subjected to a moment load by the vertical bearing member 33 disposed on the side surface portion disposed in the vertical direction. The slanting sliding bearing is rotatably supported, and the vertical bearing member 33 of the sliding bearing 3 is biased and disposed on the inner peripheral side of the tower 2. Therefore, the sliding bearing structure which can divide the circumferential direction into a plurality of numbers can be inserted from the upper portion of the tower 2 to the rotating portion 32 which is a sliding portion on the nacelle 3 side by a crane or the like. It is assembled and assembled on the tower 2 in a smart manner. That is, the cylindrical member fixed to the upper end portion of the erected tower 2 is inserted from above by the hoisting of the nacelle 3 to which the rotating portion 32 is fixed. The inside of the vertical bearing member 33 and the horizontal bearing member 34 fixed to the rotating portion 32 are slidably coupled with respect to each other, so that the assembly of the slidable sliding bearing 30 and the assembly of the nacelle 3 are completed simultaneously. With such a sliding bearing 30, when the nacelle 3 is rotated, a frictional force larger than that of the previous structure using the rolling bearing is generated at the fixing portion 31 and the (four) faces of the vertical bearing member 33 and the horizontal bearing member 34. Therefore, since the rotational force necessary for the rotation of the nacelle 3 is increased by the sliding bearing 3, it is necessary to increase the output of the yaw motor 23. However, the sliding suction 30 can also be used as a (four) force for the load of the yaw motor 23 which increases the output of the motor and increases the output of the yaw motor 23. Therefore, in the yaw rotation device 2 of the second-stage biasing sliding bearing 30, there is no need for the brake mechanism necessary for stopping the rotation of the machine 3 (the brake disc and the brake m shown in Fig. 18 contribute to the weight reduction of the nacelle 3) And the cost is reduced. In addition, the hydraulic circuit that does not require the operation of the brake mechanism is required, so that the piping and valves of the hydraulic pump can be reduced and simplified. 141085.doc •10- 201100633 Moreover, if the aforementioned sliding bearing is used 3〇, it is possible to realize the division of the vertical bearing material 33 and the horizontal bearing material 34, the fly 4 brother blade bearing material, ^ 0 to suppress the increase in the bearing cost associated with the enlargement of the bearing, and the transfer restriction can be called In the case of the case where the size of the member is reduced in size, the swaying sliding bearing 3 of the present embodiment is not limited to the various modifications described above, and the following is also possible. The same portions as those in the above-described embodiments are denoted by the same reference numerals, and the detailed description thereof will be omitted.

The first modification shown in FIG. 4 is configured such that a sliding portion in the vertical direction is disposed between the fixing portion 31 formed on the upper portion of the tower 2 and the rotation (four) which is suspended from the lower surface of the base member 22. The vertical sliding bearing material of the surface is used as the main sliding bearing material. In this case, the (4) part (4) (4) is fixed to the outer peripheral surface of the cylindrical member ^ at the upper end of the tower 2, and the rotating portion 32 of the fixed vertical bearing (4) is disposed in the tower. The outer side of the frame 2. In the example of the illustration, the horizontal bearing member 34 is also provided between the upper end portion of the tower 2 and the lower surface of the base member 22, and is supported in the vertical direction as in the above-described embodiment. In the configuration of the first modification, the vertical bearing member 33 of the slanting sliding bearing 3 is fixed to the rotating portion 32 and disposed on the outer peripheral side of the tower 2, so that The same effect as the above-described embodiment. In this case, the biasing motor (not shown) is fixed to the appropriate position of the tower 2, for example, to rotate the drive gear (not shown) to the cylindrical member. Inner peripheral surface formed with the drive gear A fixed gear (not shown) is shown in Fig. 5. The second modification shown in Fig. 5 is formed on the end of the tower 2 at 141085.doc -11 - 201100633. The fixed portion 31 of the crucible is suspended from The vertical/moon bearing material 3 3 which is formed inside and outside the sliding surface of the lower surface of the base member 22 is disposed as a main sliding bearing member. The cylindrical member fixed to the upper end of the tower 2 has an inner circumferential surface and an outer circumferential surface, and the rotating portion 32 to which the vertical bearing member 33 is fixed is disposed inside and outside the tower 2. Further, in the configuration example of the drawing, The horizontal bearing member 34 is also provided between the upper end portion of the tower 2 and the lower surface of the base member 22, and is configured to support both the inner and outer surfaces in the vertical direction and the three surfaces in the horizontal direction, similarly to the above-described embodiment. In the configuration of the second modification, the vertical bearing member 33 of the slanting sliding bearing 3 is fixed to the rotating portion 32 and disposed on the inner peripheral side and the outer peripheral side of the tower 2, thereby achieving the above-described implementation. The same effect of the shape. Also, for the case of β Hai The yaw motor (not shown) may be provided in an appropriate place such as the inside of the tower 2. The third modification of Fig. 6 and the above-described embodiment in which the vertical bearing member 33 is fixed to the rotating portion 32 side may be employed. Unlike the modified example, the vertical bearing material is fixed to the side of the fixing portion 31. In the illustrated example, the cylindrical member 2a having a smaller diameter than the tower body 2b is fixedly attached to the upper end portion of the tower 2, and In the cylindrical member 固定, the vertical bearing member 33 is fixed to the outer peripheral surface as the fixing portion 3, that is, the vertical bearing member 33 of the slanting sliding bearing 3 is fixed to the fixing portion 31 and disposed on the inner peripheral side of the tower 2. In the case, the cylindrical member 2a is fixed to the upper end portion of the tower body 2b via the flange portion 2C formed at the lower end portion. 141085.doc -12- 201100633 Further, in the configuration example of the illustration, the vertical bearing except the aforementioned In addition to the material 33, a horizontal bearing member 34 is also provided between the upper end portion of the tower body 2 (specifically, the upper surface of the flange portion 2c) and the lower end surface of the rotating portion 32. Therefore, the third modification shown in FIG. 6 is the same as the embodiment of FIG. 1 and FIGS. 2A and 2B described above, and is configured to support the inner surface of the tower in the vertical direction and the two surfaces in the horizontal direction. The same effect is achieved in the embodiment. In the fourth modification shown in Fig. 7, the vertical bearing member 3 3 is fixed to the side of the fixing portion 31 as in the third modification described above. In the example of the illustration, the cylindrical member 2a which is larger than the tower main body 2b is fixedly attached to the upper end portion of the tower 2, and the vertical member 33 is fixed to the inner peripheral surface by using the cylindrical member 2a as the fixing portion 3'. In other words, the vertical bearing member 33' of the fourth modification is different from the third modification of the inner peripheral side of the tower 2, and is fixed to the fixing portion 31 and disposed on the outer peripheral side of the tower 2. In this case, the cylindrical member 2a is fixed to the upper end portion of the tower body via the flange portion 2 formed at the lower end portion. In the configuration example of the illustration, the above-mentioned vertical bearing member 33 is excluded. The horizontal bearing member 34 is also provided between the upper end portion of the tower body 2 (specifically, the upper surface of the flange portion 2C) and the lower end surface of the rotating portion 32. Therefore, the fourth modification shown in Fig. 7 is The first modification of Fig. 4 is the same as the configuration of the outer surface of the tower in the vertical direction and the two surfaces in the horizontal direction. Therefore, the same operational effects as those of the above-described embodiment can be obtained. In the same manner as the third modification and the fourth modification described above, the vertical bearing member 33 is fixed to the side of the fixed portion 31. 141085.doc -13- 201100633 In the illustrated configuration example, the upper end portion of the tower 2 is fixed. The double cylindrical member 2a having a smaller diameter and a larger diameter than the tower main body 2b is attached, and the double cylindrical member 2a' is used as the fixing portion 31 to fix the vertical bearing member 33 on the opposing surface of the double cylinder. The vertical bearing member 33 of the modified example is combined with the third change on the inner peripheral side of the tower 2 For example, the fourth modification is disposed on the outer peripheral side of the tower 2, and is fixed to the fixed portion 31 and disposed on the inner circumferential side and the outer circumferential side of the tower 2. In this case, the double cylindrical member 2a is via the double cylinder member 2a. The flange portion 2c formed at the lower end portion is fixed to the upper end portion of the tower body 2b.

Further, in the configuration example of the figure, in addition to the vertical bearing member 33 described above, a horizontal bearing is also provided between the upper end portion of the tower body 2 (specifically, the upper surface of the flange portion 2c) and the lower end surface of the rotating portion. Material 34. Therefore, the fifth modification shown in FIG. 8 is the same as the second modification of FIG. 5 described above, and is supported by the above-described embodiment because it supports both the inner and outer surfaces in the vertical direction and the three surfaces in the horizontal direction. The same effect.

As described above, in the nacelle 3 of the above-described embodiment, the nacelle 3 provided on the upper portion of the tower 2 is mainly subjected to a swaying sliding bearing which is subjected to a moment load by the vertical bearing member 33 disposed on the upper surface of the upper surface portion. 3〇 and rotatably supported, and at least one force on the inner circumference side and the outer circumference side of the tower 2 is provided with a vertical drawing material 33 of a slanting sliding bearing 3〇, so that it can be divided by construction (structural deviation) The sliding bearing 3G is rocked and the sliding portion is inserted into the upper portion of the tower 2 from the upper portion of the tower 2, and the sliding portion can be easily assembled. However, in the above-described embodiment and the sliding bearing 3 of each modification, the vertical bearing member 33 is provided. The length of the side portion (H) should be set to be at least twice the horizontal length (l) of the sliding bearing material which is mainly subjected to the moment load at the flat portion. 14l085.doc -14- 201100633 The length of the side portion of the case (Η 'The length of the vertical bearing material 33 that slides in contact with the surface of the fixed portion 3丨 (see Fig. 2A); the horizontal direction (L) of the sliding bearing material is shown in Fig. 2A and the second embodiment based on Fig. 12 Sliding bearing 3 0 A as described later In the horizontal direction of the horizontal bearing material 34, which is mainly subjected to a moment load in the flat portion (see Fig. 12), the sliding bearing 30 which sufficiently ensures the length (H) of the side portion of the vertical bearing member 33 can be surely received with the nacelle. The self-weight is significantly increased compared to the input torque load from the machine side 3, that is, the area of the sliding surface is increased by sufficiently ensuring the length (H) of the side portion of the vertical 轴承 bearing material 33, even from the machine test The torque load having a large lateral action on the 3 side can suppress the surface pressure and smoothly rotate. Further, in the above-described embodiment and its modifications, the sixth modification shown in FIG. 9 or the seventh modification shown in FIG. For example, the horizontal contact surface of the sliding bearing member is preferably an inclined surface or a curved surface. In the sixth modification shown in Fig. 9, a slanting bearing member 35 is provided at an upper end portion of the vertical bearing member 33. The inclined bearing surface 35 which is inclined from the outer peripheral side of the tower 2 toward the center of rotation of the nacelle 3 is an inclined surface of the above-mentioned horizontal bearing material 34. The inclined bearing material 35 having such an inclined surface is mainly used to bear the weight of the nacelle 3 Horizontal bearing In addition to the function of 34, the torque load can also be withstood. Therefore, the inclined bearing member 35 shown in this modification mainly serves as a function of the vertical bearing member 33 that receives the moment load. That is, the inclined bearing member 35 can withstand the inclined surface. The moment load can reduce the moment load entering the side portion of the tower 2. The inclined bearing material 3 5 described above has the rotation center of the remaining 3 141085.doc 15 201100633 and the axis center of the tower 2 For the soapiness, that is, under the force of moving the center of the nacelle 3 toward the center of the shaft of the tower 2 and moving in the middle, the nacelle 3 is reduced to the center of the center of the tower 2 and the tower 2 The square of the war is offset, and the backlash between the meshing and driving gears can be kept constant. Therefore, the force applied to the sliding bearing of the flat bearing is not easy to occur, and it can prevent the abrasion of the sliding bearing material. Therefore, since the upper portion of the tower 2 is not loosened, the rotation of the nacelle 3 provided at the upper end portion of the tower 2 is stabilized. Further, the upper end portion of the cylindrical member 2a connected to the inclined bearing surface 35 is of course also formed as an inclined surface in conjunction with the inclined bearing surface 35. Further, as shown in Fig. 10, the seventh deformation {column is used, and the (four) surface bearing member 36 is taken in place of the above-described inclined bearing member 35. In the curved bearing (four), the curved surface of the horizontal bearing member 34 is formed by forming a concave curved surface from the outer peripheral side of the tower 2 to the downward inclined surface of the shaft center side. The curved surface bearing material 36 having such a concave curved surface can withstand a moment load in addition to the force of the horizontal bearing material μ which mainly bears the weight of the nacelle 3. Therefore, the curved bearing material 36 is mainly used to assist the function of the vertical bearing member 33 which is subjected to the moment load. Further, the curved bearing material 36 described above has the same alignment as that of the inclined bearing member 35, and has the alignment of the rotating shaft with the shaft center of the tower 2. Therefore, it is possible to prevent or suppress the partial wear caused by the sliding bearing material. The rotation of the machine provided at the upper end of the tower 2 is stabilized. Further, the upper end portion of the cylindrical member 2a connected to the curved bearing surface 36 is, of course, also formed as an inclined surface (convex curved surface) in conjunction with the curved bearing surface 36. Further, the above-mentioned inclined bearing material 35 and curved bearing material 36 are both descending toward the center of the shaft of the tower 141085.doc -16 - 201100633, but if it is changed from the axial center side to the outer circumferential surface of the tower 2 The same effect can be obtained by the inclined surface or curved surface in the opposite direction of the side drop. Further, the curved bearing material 36 is not limited to the aforementioned concave curved surface, and may be, for example, a convex curved surface. : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : 弹性 弹性 弹性 弹性 弹性 弹性 弹性 弹性 弹性 弹性 弹性 弹性 弹性 弹性 弹性 弹性 弹性 弹性 弹性- The bomb of the chemical (four) _ example. In the base member of the (4) 33a type of the vertical wire bearing member, for example, the rotating portion of the fixed vertical bearing member 33 is provided with two portions 32a' and the vertical bearing material % and the elastic member η are disposed at the material position. The cover plate 38 having the convex portion is locked by bolts on the opening portion on the opposite side. Further, in the present invention, as shown in Fig. 11B, a plate-shaped holding member that supports the opposite end portions of the above-described elastic members 37 is provided, and a fulcrum portion 37b is formed with respect to the holding member 37a. As a result, the elastic member is held in a state in which the vertical bearing member 33 and the elastic member 37 are housed in a predetermined position in the recess 32a, and the retainer portion is supported by the projection portion. Again. Therefore, even if the amount of tilt of the nacelle 3 relative to the tower 2 is likely to exceed the absorbable range of the elastic member 37 and the vertical bearing member 33 is partially stressed, the vertical bearing member 33 can be adjusted by the fulcrum support. The resulting side P is made of dust to make the contact surface uniform. Therefore, it is possible to further reliably prevent the partial force of 141085.doc 201100633, and it is possible to prevent or suppress the partial wear caused by the sliding bearing material and to stabilize the rotation of the nacelle 3. <Second Embodiment> Next, a second embodiment of the wind power generator of the present invention will be described with reference to Figs. 12 to 14 .

The wind power generator 具备 having such a slanting sliding bearing 30B has a sliding bearing structure of a detachable structure and can reduce the diameter of the upper portion of the tower 2. In other words, the θ-shaped fixing portion 31B is provided on the upper portion of the tower 2, and the vertical bearing member 33 and the horizontal bearing member are fixed to the inner circumferential surface of the rotating portion 32B, and are disposed on the inner peripheral side and the outer peripheral side of the tower 2. On both sides, the bolt connecting the upper part of the tower 2 and the nacelle 3 can be arranged symmetrically. Therefore, the bending force can be reduced due to the bending moment of the bolt 1410S5.doc -21- 201100633, so the bolt root can be reduced. The fourth embodiment is described below with reference to Fig. 16. The same applies to the wind power generator of the present invention. In the embodiment, the nacelle 3 provided on the upper portion of the tower 2 is mainly rotatably supported by the yaw of the engine that receives the moment load from the upper and lower plane portions.

In the embodiment of the figure The fixing portion 31C and the horizontal bearing member 34 have a curved shape, and the yaw sliding bearing 30C has alignment. The curved surface shown is a concave curved surface that descends toward the center of the tower 2, but may be convex or inclined. The swaying sliding bearing 3〇c having such an alignment can prevent or suppress the partial wear caused by the partial force of the sliding bearing portion when the nacelle 3 rotates, so that the rotation of the nacelle 3 can be stabilized. In the fifth embodiment, the fifth embodiment will be described with reference to Fig. 17 and irB. The same portions as those of the above-described embodiments are denoted by the same reference numerals, and the detailed description thereof will be omitted.
