Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary supporting of a yaw system, in particular to a highly stable yaw lubricating gear fixing plate. Background Technique

[0002] The yaw system of a wind turbine generator is a key system, and its main function is to make the wind turbine face the main wind direction, so as to make full use of wind energy and improve the power generation efficiency of the wind turbine generator. The yaw system can be divided into two main types: passive yaw and active yaw. Passive yaw relies on the wind force to complete the windward action of the wind turbine through relevant mechanisms. Therefore, the design and operation of the yaw system are crucial for ensuring the safety and efficiency of the wind turbine generator.

[0003] In the prior art, due to the particularity of the structure and certain followability of the passive yaw system of a wind turbine generator, large displacement friction is inevitable between the inner ring gear of the yaw frame and the transmission gear set. Even with the auxiliary cooperation of a lubricating pump, poor friction still occurs between the transmission gear and the inner ring gear. The force brought by strong extrusion may cause poor wear or even micro-deformation to the structure of the gear fixing plate, thereby affecting the stable transmission and good operation of the gear set. Content of the Utility Model

[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Simplifications or omissions may be made in this part, as well as in the abstract of the specification and the title of the utility model of this application, to avoid obscuring the purpose of this part, the abstract of the specification and the title of the utility model. Such simplifications or omissions shall not be used to limit the scope of the utility model.

[0005] Therefore, the purpose of the utility model is to provide a highly stable yaw lubricating gear fixing plate to solve the problem that in the prior art, during the use of the yaw lubricating gear fixing plate, poor friction may occur between the transmission gear and the inner ring gear, and the force brought by strong extrusion may cause wear or even micro-deformation to the structure of the gear fixing plate, thereby affecting the stable transmission and good operation of the gear set as described in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a highly stable yaw lubricating gear fixing plate, which includes a fixed bottom plate. Adjacent to the fixed bottom plate are a gear shaft sleeve one and a gear shaft sleeve two. The fixed bottom plate also has an adjustment groove near the gear shaft sleeve one. A sliding seat slides inside the adjustment groove. The sliding seat slides along the direction of the adjustment groove and forms a relative or opposite movement with the gear shaft sleeve one. In the middle of the upper part of the sliding seat, there is also a gear shaft sleeve three that cooperates with the gear shaft sleeve one. At one end in the movement direction of the sliding seat, there is a first pressing adjustment part, and at the other end in the movement direction of the sliding seat, there is a second pressing adjustment part.

[0007] As a preferred solution of a highly stable yaw lubricating gear fixing plate according to the present utility model, strip-shaped sliders are provided on both sides of the sliding seat, and sliding grooves that are slidably matched with the strip-shaped sliders are provided inside the adjusting groove.

[0008] As a preferred solution of a highly stable yaw lubricating gear fixing plate according to the present utility model, the first pressing and adjusting member and the second pressing and adjusting member are hydraulic rods, and the output shafts of the hydraulic rods abut against the sliding seat;

[0009] An installation groove for installing the first pressing and adjusting member and the second pressing and adjusting member and communicating with the adjusting groove is further provided on the fixed bottom plate.

[0010] As a preferred solution of a highly stable yaw lubricating gear fixing plate according to the present utility model, pressure sensors are further provided at the connection between the first pressing and adjusting member and the second pressing and adjusting member and the sliding seat.

[0011] As a preferred solution of a highly stable yaw lubricating gear fixing plate according to the present utility model, a plurality of stud feet are provided in the inner circumferential direction of the fixed bottom plate, a protective cover is further matched at the upper end of the fixed bottom plate, and a plurality of screw holes corresponding to the stud feet are provided in the circumferential direction of the protective cover.

[0012] As a preferred solution of a highly stable yaw lubricating gear fixing plate according to the present utility model, an avoidance hole corresponding to the gear shaft sleeve three is further provided at the top of the protective cover.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this highly stable yaw lubricating gear fixing plate, when a sudden abnormal swing occurs in the yaw frame, the driven gear inside the gear shaft sleeve three will have displacement friction with the inner ring teeth of the yaw frame. When this displacement amplitude is greater than the positive and negative difference of the normal range, the pressure sensors on both sides of the sliding seat will timely sense and detect the pressure value corresponding to the positive and negative difference and the deviation value calculated by the system. Subsequently, the system will control the first pressing and adjusting member and the second pressing and adjusting member to finely adjust the positions of the sliding seat and the driven gear accordingly, so that a certain avoidance distance is maintained between the driven gear and the inner ring teeth, which can effectively prevent the adverse wear and damage deformation caused by sudden strong extrusion to the driven gear and the fixed bottom plate, thereby ensuring the stable transmission and good operation of the gear set.

Specific embodiments

[0018] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings.

[0019] Secondly, the present utility model will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model here. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0020] In order to make the purpose, technical solution, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0021] Figures 1 - 3 Shown is a schematic diagram of the entire structure of a highly stable yaw lubricating gear fixing plate of the present utility model. Please refer to Figures 1 - 3 , A highly stable yaw lubricating gear fixing plate of this embodiment includes a fixed base plate 100. A first gear shaft sleeve 110 and a second gear shaft sleeve 120 are adjacently arranged on the fixed base plate 100. The fixed base plate 100 also has an adjustment groove 130 near the first gear shaft sleeve 110. A sliding seat 200 slides inside the adjustment groove 130. The sliding seat 200 slides along the direction of the adjustment groove 130 and forms a relative or opposite movement with the first gear shaft sleeve 110. A third gear shaft sleeve 210 that cooperates with the first gear shaft sleeve 110 is also arranged at the center of the upper part of the sliding seat 200. A first pressing adjustment member 300 is arranged at one end of the sliding seat 200 in the movement direction, and a second pressing adjustment member 310 is arranged at the other end of the sliding seat 200 in the movement direction.

[0022] On both sides of the sliding seat 200, there are strip-shaped sliders 220. Inside the adjustment groove 130, there is a sliding groove 131 that slidably matches the strip-shaped sliders 220. By the cooperation of the strip-shaped sliders 220 and the sliding groove 131, the sliding seat 200 can be linearly positioned, making the sliding seat 200 move more linearly and stably back and forth. The first pressing adjustment member 300 and the second pressing adjustment member 310 are hydraulic rods, and the output shafts of the hydraulic rods abut against the sliding seat 200. Among them, on the fixed bottom plate 100, there is also an installation groove 140 for installing the first pressing adjustment member 300 and the second pressing adjustment member 310 and communicating with the adjustment groove 130. It can be understood that the hydraulic rod has excellent bearing capacity, high output precision and good durability, and is suitable for the relative fine adjustment of the position of the sliding seat 200 in this device. Specifically, in this embodiment, the gear shaft sleeve three 210 is used to install the wheel shaft of the passive gear meshing and linking with the yaw system, the gear shaft sleeve one 110 is used to install the wheel shaft of the intermediate transmission gear, and this transmission gear meshes with the passive gear, while the gear shaft sleeve two 120 is used to install the wheel shaft of the end gear linked with the generator set, and the end gear meshes with the transmission gear. More specifically, at the connection between the first pressing adjustment member 300 and the second pressing adjustment member 310 and the sliding seat 200, there is also a pressure sensor 400. During use, when the yaw frame has a sudden abnormal swing, the passive gear inside the gear shaft sleeve three 210 will have displacement friction with the inner ring teeth of the yaw frame. When this displacement amplitude is greater than the good positive and negative difference, the pressure sensors 400 on both sides of the sliding seat 200 will timely sense and detect the pressure value corresponding to the positive and negative difference and the deviation value calculated by the system. Subsequently, the system will control the first pressing adjustment member 300 and the second pressing adjustment member 310 and make corresponding fine adjustments to the positions of the sliding seat 200 and the passive gear, so that a certain avoidance distance is maintained between the passive gear and the inner ring teeth, which can effectively prevent the adverse wear and deformation caused by sudden strong extrusion to the passive gear and the fixed bottom plate 100, thereby ensuring the stable transmission and good operation of the gear set. It should be noted that after each adjustment is completed and when the yaw frame tends to be in a stable state, the system will control the first pressing adjustment member 300 and the second pressing adjustment member 310 to restore the original output stroke, that is, restore the sliding seat 200 to its original position.

[0023] Furthermore, on the inner peripheral side direction of the fixed bottom plate 100, there are a plurality of stud feet 150. On the upper end of the fixed bottom plate 100, there is also a matching cover 500, and on the peripheral side direction of the cover 500, there are a plurality of screw holes 510 corresponding to the stud feet 150. It can be understood that by setting the cover 500, the upper part of the fixed bottom plate 100 where the gear set and the stable adjustment unit are installed can be externally protected, and through the cooperation of the stud feet 150, the screw holes 510 and bolts, it is convenient to disassemble and maintain between the cover 500 and the fixed bottom plate 100.

[0024] Further, an avoidance hole 520 corresponding to the third gear shaft sleeve 210 is also formed in the top of the protective cover 500. Since the passive gear inside the third gear shaft sleeve 210 will contact the yaw frame, the passive gear can perform normal operations through the avoidance hole 520.

[0025] In summary, for a highly stable yaw lubricating gear fixing plate according to this embodiment, when the yaw frame has sudden abnormal swinging, the passive gear inside the third gear shaft sleeve 210 will have displacement friction with the inner ring teeth of the yaw frame. When this displacement amplitude is greater than the positive and negative difference of the normal range, the pressure sensors 400 on both sides of the sliding seat 200 will timely sense and detect the pressure value corresponding to the positive and negative difference and the deviation value calculated by the system. Subsequently, the system will control the first top pressure adjusting member 300 and the second top pressure adjusting member 310 to finely adjust the positions of the sliding seat 200 and the passive gear accordingly, so that a certain avoidance distance is maintained between the passive gear and the inner ring teeth, effectively preventing the adverse wear and damage deformation caused by sudden strong extrusion to the passive gear and the fixed bottom plate 100, thereby ensuring the stable transmission and good operation of the gear set. After each adjustment is completed and when the yaw frame tends to be in a stable state, the system will control the first top pressure adjusting member 300 and the second top pressure adjusting member 310 to restore to the original output stroke.

[0026] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources.
