Description

Technical Field

[0001] The utility model belongs to the field of output gears, and more specifically, it is an output gear for a wind power gearbox. Background Art

[0002] The output gear of a wind power gearbox is one of the key mechanical components in a wind power generation unit. It is responsible for converting the low-speed rotation generated by the wind turbine through the gear transmission system into the high-speed rotation required by the generator. This process is crucial for the efficiency and reliability of the wind power system.

[0003] When the output gear in the wind power gearbox is in use, it is first connected to the motor through the output gear. The motor drives the output gear to rotate, and the output gear transmits the output force to the driven gear, thereby realizing multi-gear transmission and facilitating the conversion of the rotational force. However, when the existing output gear is in use, it will output power to the meshing gear. Due to the friction generated during its transmission, the output gear is prone to deformation under long-term friction, thus affecting the effect of power output.

[0004] In summary, the utility model provides an output gear for a wind power gearbox to solve the above problems. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] An output gear for a wind power gearbox includes an annular seat. Teeth are fixedly connected to the surface of the annular seat. A connecting shaft is arranged in the inner cavity of the annular seat. A support plate is fixedly connected to the surface of the connecting shaft, and a stress plate is fixedly connected to the end of the support plate away from the connecting shaft. An oil injection hole is opened on the left side of the annular seat. A sealing cover is arranged on the left side of the annular seat. An oil outlet hole is opened on the surface of the annular seat and on one side of the teeth.

[0007] Further, in the utility model, a clamping groove is opened on one side of the connecting shaft. The external output shaft extends into the inner cavity of the clamping groove and is movably connected to the inner cavity of the clamping groove. The inner wall of the oil injection hole is provided with threads.

[0008] Further, in the utility model, the number of the support plates is four, and they are evenly distributed on the surface of the connecting shaft. The end of the stress plate away from the support plate is fixedly connected to the inner wall of the annular seat. An arc-shaped plate is fixedly connected between every two support plates, and the number of the arc-shaped plates is four.

[0009] Further, in the utility model, a connecting block is fixedly connected to the right side of the sealing cover. Threads are provided on the surface of the connecting block. The end of the connecting block away from the sealing cover penetrates into the inner cavity of the oil injection hole and is threadedly connected to the inner cavity of the oil injection hole.

[0010] Furthermore, in the present utility model, a sealing ring is fixedly connected to the right side of the cover and on the surface of the connecting block. One side of the sealing ring away from the cover contacts the ring seat and blocks the oil injection hole.

[0011] Furthermore, in the present utility model, a gasket is fixedly connected to the end of the tooth away from the ring seat. The gasket is made of polyurethane material. The support plate, stress plate, and arc plate are all made of superalloy. The ring seat and teeth are both made of cobalt-based alloy.

[0012] Beneficial effects: The present utility model has the following beneficial effects:

[0013] In the present utility model, the external output shaft drives the connecting shaft to rotate, causing the connecting shaft to drive the support plate and stress plate to rotate.

[0020] To better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows. In this disclosure, aspects of the present utility model are described with reference to the drawings, and many illustrative embodiments are shown in the drawings. The embodiments of this disclosure do not necessarily define all aspects of the present utility model. It should be understood that the various concepts and embodiments introduced above, as well as those concepts and implementation manners described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in the present utility model are not limited to any implementation manner. Additionally, some aspects disclosed in the present utility model can be used alone, or in any suitable combination with other aspects disclosed in the present utility model.

[0021] Embodiment 1

[0022] As Figures 1-4 shown, this is the first embodiment of the present utility model. This embodiment provides an output gear for a wind power gearbox, which includes a ring seat 1. Teeth 2 are fixedly connected to the surface of the ring seat 1. A connecting shaft 3 is arranged in the inner cavity of the ring seat 1. A support plate 4 is fixedly connected to the surface of the connecting shaft 3, and a stress plate 5 is fixedly connected to one end of the support plate 4 away from the connecting shaft 3. An oil injection hole 6 is opened on the left side of the ring seat 1. A sealing cover 7 is arranged on the left side of the ring seat 1. An oil outlet hole 8 is opened on the surface of the ring seat 1 and on one side of the teeth 2.

[0023] As Figures 1-4 shown, the external output shaft drives the connecting shaft 3 to rotate, so that the connecting shaft 3 drives the support plate 4 and the stress plate 5 to rotate. The stress plate 5 drives the ring seat 1 and the teeth 2 to rotate, so that the teeth 2 transmit the power outward, thereby facilitating the conversion of the rotational force. By using the support plate 4 and the stress plate 5 to support the ring seat 1 and the teeth 2, the overall weight can be reduced, the load during rotation can be reduced, and the friction during force transmission can be initially reduced. At the same time, lubricating oil is injected into the interior of the ring seat 1 through the oil injection hole 6, and the sealing cover 7 seals the oil injection hole 6 to prevent the leakage of the lubricating oil. Furthermore, when rotating and transmitting force, the centrifugal force will cause the lubricating oil inside the ring seat 1 to flow to the surface of the teeth 2 through the oil outlet hole 8, increasing the lubricity of the teeth 2, thereby reducing the friction of force transmission and effectively preventing the deformation and wear caused by friction.

[0024] Embodiment 2

[0025] Referring to Figures 1-3 , this is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0026] In this embodiment, a card slot 9 is opened on one side of the connecting shaft 3. The external output shaft extends into the inner cavity of the card slot 9 and is movably connected to the inner cavity of the card slot 9. The inner wall of the oil injection hole 6 is provided with threads.

[0027] There are four support plates 4, which are evenly distributed on the surface of the connecting shaft 3. The end of the stress plate 5 away from the support plate 4 is fixedly connected to the inner wall of the ring seat 1. An arc plate 10 is fixedly connected between every two support plates 4, and there are four arc plates 10.

[0028] like Figures 1-3 As shown, the card slot 9 facilitates connection with the external output shaft, thereby facilitating the external output shaft to transmit the rotational force to the connecting shaft 3. By setting four support plates 4, the stability of the support plate 4 supporting the ring seat 1 can be improved. The stress plate 5 contacts the ring seat 1, thereby increasing the supporting area of ​​the ring seat 1. By setting the arc plate 10, the pressure on the support plate 4 can be dispersed, thereby improving its bearing capacity.

[0029] Example 3

[0030] Reference Figures 1-4 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0031] In this embodiment, a connecting block 11 is fixedly connected to the right side of the cover 7. The surface of the connecting block 11 is provided with threads. The end of the connecting block 11 away from the cover 7 passes through the inner cavity of the oil filling hole 6 and is threadedly connected to the inner cavity of the oil filling hole 6.

[0032] A sealing ring 12 is fixedly connected to the right side of the sealing cover 7 and on the surface of the connecting block 11 . The side of the sealing ring 12 away from the sealing cover 7 contacts the ring seat 1 and shields the oil filling hole 6 .

[0033] The end of the tooth 2 away from the ring seat 1 is fixedly connected with a gasket 13, the gasket 13 is made of polyurethane material, the support plate 4, the stress plate 5 and the arc plate 10 are all made of high-temperature alloy, and the ring seat 1 and the tooth 2 are all made of cobalt-based alloy.

[0034] like Figures 1-4 As shown, the connection block 11 is driven to rotate by the cover 7, so that the connection block 11 gradually enters the interior of the oil filling hole 6 and closes the oil filling hole 6. At the same time, the sealing ring 12 will contact the ring seat 1 to prevent the leakage of lubricating oil. The gasket 13 is made of polyurethane material, which has excellent elasticity and wear resistance, and can buffer the collision force generated when the tooth 2 contacts the driven gear. The support plate 4, the stress plate 5 and the arc plate 10 are made of high-temperature alloy, so that the support plate 4, the stress plate 5 and the arc plate 10 have good thermal conductivity and hardness, and can stably support the ring seat 1 and the tooth 2 while conducting away the heat on the surface of the ring seat 1 and the tooth 2 to achieve heat dissipation. The ring seat 1 and the tooth 2 are made of cobalt-based alloy, so that the ring seat 1 and the tooth 2 have extremely high hardness and wear resistance, and can maintain stable performance in a high temperature environment.

[0035] During use, first inject lubricating oil into the interior of the ring seat 1 through the oil injection hole 6. After the injection is completed, the cover 7 can be taken to align the connecting block 11 driven by the cover 7 with the oil injection hole 6. Then, rotate the cover 7. The cover 7 drives the connecting block 11 to rotate, causing the connecting block 11 to gradually enter the interior of the oil injection hole 6 and close the oil injection hole 6. At the same time, the sealing ring 12 will contact the ring seat 1 to prevent the leakage of lubricating oil. When operating, the external output shaft drives the connecting shaft 3 to rotate. While the connecting shaft 3 rotates, it drives the rotation. The support plate 4 transmits the force to the stress plate 5, causing the stress plate 5 to rotate. And the stress plate 5 drives the ring seat 1 and the tooth 2 to rotate, enabling the tooth 2 to transmit the rotational power outward to the driven gear, thus facilitating the conversion of the rotational force. During the process of rotating and transmitting the force, the support plate 4 and the stress plate 5 are used to support the ring seat 1 and the tooth 2. This can not only reduce the overall weight and the load generated by the weight during rotation, but also initially reduce the friction during force transmission. At the same time, during the process of rotating and transmitting the force, the centrifugal force generated by the rotation will cause the lubricating oil inside the ring seat 1 to flow through the oil outlet hole 8 to the surface of the tooth 2, increasing the lubricity of the tooth 2, thereby reducing the friction of force transmission. And when the tooth 2 is in meshing contact with the external gear, the gasket 13 can buffer the collision force generated by the contact, thus effectively preventing the deformation and wear caused by friction.
