Technical Field

[0001] This utility model is a gearbox cover with a quick-release inspection window, belonging to the field of gearbox technology. Background Technology

[0002] Gearboxes have a wide range of applications, such as in wind turbine generators. They are a crucial mechanical component widely used in wind turbine generators. Their main function is to transmit the power generated by the wind turbine under wind force to the generator, enabling it to achieve the required rotational speed. Typically, the wind turbine's rotational speed is very low, far below the speed required for generator operation. This speed increase is achieved through the speed-increasing action of the gearbox's gear pairs; hence, gearboxes are also called speed increasers.

[0003] In the existing technology, when the internal parts of the gearbox body need maintenance, the user needs to remove the screws on the surface of the gearbox cover with tools. This is inconvenient and increases the maintenance time for workers. There is an urgent need for a gearbox cover with a quick-release inspection window to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gearbox cover with a quick-release maintenance window to solve the problems mentioned in the background art. This utility model has good practicality. When the gearbox body needs to be repaired, the gearbox cover can be opened by disassembling the components without affecting the sealing between the gearbox cover and the gearbox body, thereby reducing the maintenance time of workers.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a gearbox cover with a quick-release maintenance window, comprising a gearbox body and a gearbox cover, wherein multiple fixing ribs are fixedly connected to the front and rear ends of the gearbox body, and two fixing blocks are fixedly connected to the front and rear ends of the gearbox cover, and a downward pressing clip is fixedly connected to the lower end of each of the multiple fixing blocks.

[0006] The gearbox body has two sets of disassembly and assembly components at both its front and rear ends. One set of disassembly and assembly components includes a mounting square shell, a sliding chuck, a spring, a connector, a limiting sleeve, a sliding fixing rod, and a threaded layer. The mounting square shell is fixedly connected to the front end of the gearbox body. The sliding chuck is slidably connected inside the mounting square shell. The spring is fixedly connected to the left end of the sliding chuck. The connector is fixedly connected to the front end of the sliding chuck. The limiting sleeve is fixedly connected to the front end of the mounting square shell. The sliding fixing rod is slidably connected inside the limiting sleeve.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1-9This utility model provides a technical solution: a gearbox cover with a quick-release inspection window, comprising a gearbox body 1 and a gearbox cover 2. Multiple fixing ribs 5 are fixedly connected to the front and rear ends of the gearbox body 1. Two fixing blocks 7 are fixedly connected to the front and rear ends of the gearbox cover 2. A pressing clamp 10 is fixedly connected to the lower end of each fixing block 7. Two sets of disassembly and assembly components are provided at the front and rear ends of the gearbox body 1. One set of disassembly and assembly components includes a mounting square shell 6, a sliding clamp 11, a spring 16, a connector 15, a limiting sleeve 20, a sliding fixing rod 12, and a threaded layer 14. The mounting square shell 6 is fixedly connected to... At the front end of the gearbox body 1, the sliding chuck 11 is slidably connected to the mounting square shell 6, the spring 16 is fixedly connected to the left end of the sliding chuck 11, the connector 15 is fixedly connected to the front end of the sliding chuck 11, the limiting sleeve 20 is fixedly connected to the front end of the mounting square shell 6, the sliding fixing rod 12 is slidably connected to the limiting sleeve 20, and the threaded layer 14 is formed on the circumferential surface of the sliding fixing rod 12. This design solves the problem that when the gearbox body 1 of the original device needs maintenance, the user needs to remove the screws on the surface of the gearbox cover 2 with tools, which is not convenient during operation and increases the maintenance time of the workers.

[0026] As the first embodiment of this utility model: Both ends of the sliding clamp 11 are fixedly connected to double-sided feather plates 18. Two rectangular slide grooves 17 are opened inside the gearbox body 1, and support slide rods 19 are fixedly connected to each of the two rectangular slide grooves 17. The two support slide rods 19 cooperate with the two double-sided feather plates 18 respectively. The double-sided feather plates 18 installed at both ends of the sliding clamp 11 can support the sliding clamp 11 to slide stably within the gearbox body 1, allowing the sliding clamp 11 to lock onto the pressing clamp 10 under the elastic force of the spring 16. Two sliding strips 9 are fixedly connected to the front ends of multiple mounting square shells 6. A protective shell 8 is provided between each set of sliding strips 9. The sliding strips 9 installed at the front ends of the mounting square shells 6 can be used to place the protective shell 8, thereby protecting the disassembly and assembly components and preventing external water from entering the disassembly and assembly components when the gearbox body 1 is idle. Two pull rings 3 are rotatably connected to the upper end of the gearbox cover 2. A gearbox support 4 is fixedly connected to the lower end of the gearbox body 1. The pull rings 3 installed on the gearbox cover 2 allow the user to lift the gearbox cover 2 by passing a tool through the pull rings 3. The gearbox support 4 installed at the bottom of the gearbox body 1 can effectively support the gearbox body 1 and protect the bottom of the gearbox body 1. Multiple sliding fixing rods 12 are rotatably connected to multiple connectors 15. When it is necessary to release the sliding clamp 11 from the pressing clamp 10, the sliding fixing rod 12 needs to be pulled to the left, and then the sliding fixing rod 12 is rotated to connect the threaded layer 14 and the limiting support 13, thereby fixing the sliding clamp 11 to one side of the pressing clamp 10. Multiple sliding clips 11 and multiple pressing clips 10 cooperate with each other. When it is necessary to connect the gearbox cover 2 to the gearbox body 1, the pressing clips 10 at the bottom of the fixing block 7 need to be slid into the mounting square shell 6. The sliding clips 11 are locked by the elastic force of the spring 16, so that the gearbox cover 2 and the gearbox body 1 can be fixedly connected.

[0027] As a second embodiment of this utility model: When it is necessary to repair the gear set inside the gearbox body 1, first pinch the sliding fixing rod 12 and pull the sliding chuck 11 to the left to release the pressing chuck 10. Then pull the sliding fixing rod 12 to make the threaded layer 14 fit with the limiting support seat 13. Rotating the sliding fixing rod 12 can drive the threaded layer 14 to rotate inside the limiting support seat 13, so that the sliding chuck 11 is fixed in the mounting square shell 6. After releasing the pressing chuck 10 from the four sets of sliding chucks 11 respectively, the user can remove the gearbox cover 2 to access the gearbox. When the gear set inside the main body 1 is being repaired, and it is necessary to seal the gearbox cover 2 to the gearbox body 1, the gearbox cover 2 needs to be placed on the gearbox body 1. After aligning the four pressing heads 10 with the four mounting square shells 6, the pressing heads 10 are slid into the mounting square shells 6. The pressing heads 10 will push against the sliding heads 11 and move to the left. When the sliding heads 11 are aligned with the square groove at the left end of the pressing heads 10, the sliding heads 11 will lock the pressing heads 10 under the elastic force of the spring 16, thereby fixing the gearbox cover 2 to the gearbox body 1.
