Description

Technical Field

[0001] The utility model relates to the technical field of production and processing equipment for wind power gearboxes, and particularly relates to a precision processing device for wind power gearboxes. Background Technique

[0002] The wind power gearbox is a key mechanical component in a wind power generation unit. Its main function is to transmit the low-speed rotational power generated by the wind turbine under the action of wind through the speed-increasing effect of the gear pair to the generator and make it reach the corresponding speed to meet the power generation requirements. The design of the wind power gearbox takes into account multiple factors such as the rotational speed range of the wind turbine, wind force changes, and load requirements. It usually consists of multiple stages of gears to provide a high transmission ratio and torque amplification. It is an indispensable part of the wind power generation system and has an important impact on the performance and reliability of the generator.

[0003] Inside the wind power gearbox, the speed increase mainly relies on the meshing between the planetary gears and the other gears. During the production of the wind power gearbox, it is necessary to mill the tooth grooves of the gears so that the gears can mesh with each other, which will not affect the rotational speed. However, when milling the gears, the dropped iron powder cannot be utilized. If the iron powder generated during gear processing can be collected, the accumulation of small amounts can also achieve the effect of reuse. Content of the Utility Model

[0004] The purpose of the utility model is to provide a precision processing device for wind power gearboxes to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A precision processing device for wind power gearboxes includes a machine body. On one side of the inner wall of the machine body, a motor is installed. The output end of the motor is installed with a rotating rod through a coupling. One end of the rotating rod is connected with a fixing screw. A fixing bolt is movably arranged on the outer wall of the fixing screw. One end of the fixing screw is installed with a gear for gearbox processing. The outer wall of the rotating rod is installed with a driving wheel through a coupling. The bottom of the rotating rod is movably installed with an adsorption rod. A driven wheel is movably installed on the outer wall of the adsorption rod. A collecting block is arranged on one side of the driven wheel.

[0006] Further, a lead screw is movably installed at the bottom of the adsorption rod. A linkage wheel is installed on the outer wall of the lead screw through a coupling. A moving block is installed at the bottom of the outer wall of the collecting block. One end of the adsorption rod is installed with a driving bevel gear through a coupling.

[0007] Further, a driven bevel gear is movably installed at the top of the driving bevel gear. A top wheel is installed on the inner wall of the driven bevel gear through a coupling. A tooth groove is movably installed on the outer wall of the top wheel. A milling cutter is installed at one end of the tooth groove.

[0008] Furthermore, the adsorption rod is cylindrical, and magnets are arranged on the outer wall of the adsorption rod.

[0009] Furthermore, a cavity is arranged on the inner wall of the moving block, and the cavity of the moving block is adapted to the thread on the outer wall of the lead screw.

[0010] Furthermore, the milling cutter is semi-circular, and the shape of the outer wall of the milling cutter is adapted to the tooth groove of the gear used for machining the gearbox.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: This precision machining device for a wind power gearbox is reasonable and has the following advantages:

[0012] Through the magnets arranged on the outer wall of the adsorption rod, the generated iron filings can be effectively collected, avoiding environmental pollution or resource waste caused by the scattering of iron filings. At the same time, the present utility model also designs a collection system, enabling the adsorbed iron filings to be accurately moved under the drive of the moving block and the collection block and finally fall to the bottom of the inner wall of the machine body for collection. This not only facilitates the cleaning of iron filings but also enables the collected iron filings to be further reused, such as remelting in a furnace, etc., thereby realizing the recycling of resources, reducing production costs, and improving economic benefits;

[0013] The adsorption rod drives the milling cutter to automatically polish the tooth groove of the gear used for machining the gearbox without manual operation, greatly improving the production efficiency. Its unique design enables the milling cutter to accurately insert into the tooth groove of the gear used for machining the gearbox and polish the tooth groove evenly and meticulously through reciprocating motion. This not only ensures the accuracy of the shape and size of the tooth groove of the gear used for machining the gearbox but also makes the gears inside the gearbox mesh more tightly and smoothly, improving the use effect and service life of the gearbox.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-6 , the technical solution provided by the present invention:

[0023] Embodiment 1:

[0024] In this embodiment, a precision machining device for a wind power gearbox includes a body 1. One side of the inner wall of the body 1 is provided with a motor 2. The output end of the motor 2 is installed with a rotating rod 3 through a coupling. One end of the rotating rod 3 is connected with a fixing screw 4. The outer wall of the fixing screw 4 is movably provided with a fixing bolt 5. One end of the fixing screw 4 is installed with a gear 6 for gearbox processing. The outer wall of the rotating rod 3 is installed with a driving wheel 7 through a coupling. The bottom of the rotating rod 3 is movably installed with an adsorption rod 8. The outer wall of the adsorption rod 8 is movably installed with a driven wheel 9. One side of the driven wheel 9 is provided with a collecting block 10.

[0025] In this embodiment, the bottom of the adsorption rod 8 is movably installed with a lead screw 11. The outer wall of the lead screw 11 is installed with a linkage wheel 12 through a coupling. The bottom of the outer wall of the collecting block 10 is installed with a moving block 13. One end of the adsorption rod 8 is installed with a driving bevel gear 14 through a coupling.

[0026] In this embodiment, the top of the driving bevel gear 14 is movably installed with a driven bevel gear 15. The inner wall of the driven bevel gear 15 is installed with a top wheel 17 through a coupling. The outer wall of the top wheel 17 is movably installed with a tooth groove 16. One end of the tooth groove 16 is installed with a milling and grinding device 18.

[0027] In this embodiment, the adsorption rod 8 is cylindrical. A magnet is provided on the outer wall of the adsorption rod 8. The magnet provided on the outer wall of the adsorption rod 8 can adsorb iron filings.

[0028] In this embodiment, a cavity is provided on the inner wall of the moving block 13. The cavity of the moving block 13 is adapted to the thread on the outer wall of the lead screw 11. The lead screw 11 can drive the moving block 13 to move on its outer wall. When the moving block 13 moves, it will drive the collecting block 10 to move.

[0029] In this embodiment, the milling cutter 18 is semicircular. The outer wall shape of the milling cutter 18 is adapted to the tooth groove of the gear 6 for gearbox processing. The outer wall of the milling cutter 18 can polish the tooth groove of the gear 6 for gearbox processing.

[0030] Working principle: When in use, first the user removes the fixing bolt 5, then inserts the gear 6 for gearbox processing onto the outer wall of the fixing screw 4, and then rotates the fixing bolt 5 back onto the fixing screw 4 until the fixing bolt 5 abuts against the outer wall of the gear 6 for gearbox processing to complete the installation. At this time, the user can start the motor 2. After the motor 2 starts, it will drive the rotating rod 3 to rotate. When the rotating rod 3 rotates, it will drive the fixing screw 4 to rotate. When the fixing screw 4 rotates, it will drive the gear 6 for gearbox processing to rotate. At the same time, when the rotating rod 3 rotates, it will also drive the driving wheel 7 to rotate. When the driving wheel 7 rotates, it will drive the driven wheel 9 to rotate. When the driven wheel 9 rotates, it will drive the adsorption rod 8 to rotate. When the adsorption rod 8 rotates, one end of it will drive the driving bevel gear 14 to rotate;

[0031] Secondly, when the driving bevel gear 14 rotates, it will drive the driven bevel gear 15 to rotate. When the driven bevel gear 15 rotates, it will drive the top wheel 17 to rotate. When the top wheel 17 rotates, it will drive the tooth groove 16 to slide. When the tooth groove 16 slides, it will drive the milling cutter 18 to move reciprocally, so that the outer wall of the milling cutter 18 is inserted into the tooth groove of the gear 6 for gearbox processing, and the outer wall of the milling cutter 18 polishes the tooth groove of the gear 6 for gearbox processing. Then, through the rotation of the gear 6 for gearbox processing, the tooth groove of the gear 6 for gearbox processing can be evenly polished;

[0032] Finally, when the gear 6 for gearbox processing is being polished by the milling cutter 18, some iron filings will fall off. At this time, the magnet provided on the outer wall of the adsorption rod 8 will adsorb the iron filings. When the driven wheel 9 rotates, it will synchronously drive the linkage wheel 12 to rotate. When the linkage wheel 12 rotates, it will drive the lead screw 11 to rotate, and the lead screw 11 will drive the moving block 13 to move on its outer wall. When the moving block 13 moves, it will drive the collecting block 10 to move. When the collecting block 10 moves, it will drive the iron filings adsorbed on the magnet of the adsorption rod 8 to move until the iron filings break away from the magnet and are no longer adsorbed, and thus fall to the bottom inside the machine body 1 for collection.

[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
