Description

Technical Field

[0001] The utility model relates to the technical field of gear box assembly, in particular to an integrated shaft type gear box shaft system assembly tool. Background Art

[0002] Gearboxes are widely used, for example, in wind turbines. Gearboxes are an important mechanical component that is widely used in wind turbines. Their main function is to transfer the power generated by the wind rotor to the generator and make it reach the corresponding speed. Usually, the speed of the wind rotor is very low, far from the speed required by the generator. It must be achieved through the speed increase of the gear pair of the gearbox, so the gearbox is also called a speed increaser.

[0003] At present, the motor shaft gear input shaft has an integrated shaft structure. Before the gear shaft system is assembled, the motor rotor shaft has been assembled to the corresponding position. Therefore, the intermediate shaft and the output shaft system need to be meshed with the input shaft before they can fall smoothly. In this way, when the shaft system gear is installed as a whole, it is necessary to directly contact the corresponding gear on the motor rotor shaft. In the process of contact, it is inevitable that the gears will collide with each other, which may cause damage to the gears. Therefore, it is necessary to propose an integrated shaft gearbox shaft system assembly tool to solve the above problems. Utility Model Content

[0005] The utility model is achieved in this way:

[0006] The utility model provides an integrated shaft type gear box shaft system assembly tool, comprising a gear box structure and a shaft system gear structure installed on the gear box structure.

[0008] In an embodiment of the utility model, the motor rotor shaft is provided with a keyway, a positioning key matching the keyway is fixed on the inner side of the tooling gear, and the positioning key is clamped inside the keyway.

[0009] In an embodiment of the utility model, the tooth grooves on the tooling gear are matched with the tooth grooves on the driving gear, and the upper ends of the tooth grooves on the tooling gear are conical.

[0010] In an embodiment of the utility model, the first shaft system assembly includes a first rotating shaft, on which a first gear and a second gear are installed, the first rotating shaft is installed in a bearing groove inside the lower shell, and the second gear is meshed with the driving gear.

[0011] In an embodiment of the present invention, the second shaft system assembly includes a second rotating shaft, a third gear is mounted on the second rotating shaft, and the third gear is meshed with the first gear.

[0012] The beneficial effect of the utility model is that the utility model obtains an integrated shaft type gearbox shaft system assembly tooling through the above design. When in use, the tooling gear is clamped into the keyway of the motor rotor shaft by using the positioning key for positioning, and then the first shaft assembly and the second shaft system assembly are placed in the lower shell as a whole. At this time, the teeth on the second gear are clamped into the corresponding tooth grooves on the tooling gear, so that the second gear can slide into the tooth grooves of the driving gear along the tooth grooves on the tooling gear for meshing, and at the same time, the first rotating shaft and the second rotating shaft can be conformed to enter the bearing grooves inside the lower shell to complete the assembly.

[0021] Embodiment

[0022] Please refer to Figures 1-5 , the present utility model provides a technical solution: a gearbox structure 100 and a shafting gear structure 200 installed on the gearbox structure 100.

[0023] Please refer to Figures 1-5 , the gearbox structure 100 includes a lower housing 110, a motor rotor shaft 120 and a tooling gear 130. The motor rotor shaft 120 is installed on the lower housing 110. A driving gear 121 is key - connected to the motor rotor shaft 120. The tooling gear 130 is clamped on the motor rotor shaft 120. Here, the tooling gear 130 is made of high - strength plastic or high - strength rubber, so as to facilitate the protection of the gear and prevent damage to the driving gear 121 caused by collision.

[0024] The motor rotor shaft 120 is provided with a keyway 122. A positioning key 131 that matches the keyway 122 is fixed inside the tooling gear 130. The positioning key 131 is clamped inside the keyway 122. Here, through the settings of the keyway 122 and the positioning key 131, the tooling gear 130 can be positioned when placed, so that the tooth grooves on the tooling gear 130 can match and correspond to the tooth grooves on the driving gear 121. The tooth grooves on the tooling gear 130 and the tooth grooves on the driving gear 121 are set to match. The upper end of the tooth groove on the tooling gear 130 is tapered. This tapered setting can facilitate the rapid insertion of the teeth on the second gear 213 into the tooth grooves on the tooling gear 130.

[0025] Please refer to Figures 1-3 , the shaft system gear structure 200 includes a first shaft system assembly 210 and a second shaft system assembly 220. Both the first shaft system assembly 210 and the second shaft system assembly 220 are installed on the lower housing 110. The first shaft system assembly 210 meshes with the driving gear 121, and the second shaft system assembly 220 meshes with the first shaft system assembly 210.

[0026] The first shaft system assembly 210 includes a first rotating shaft 211. A first gear 212 and a second gear 213 are installed on the first rotating shaft 211. The first rotating shaft 211 is installed in the bearing groove inside the lower housing 110. The second gear 213 meshes with the driving gear 121. The second shaft system assembly 220 includes a second rotating shaft 221. A third gear 222 is installed on the second rotating shaft 221. The third gear 222 meshes with the first gear 212.

[0027] Specifically, the working principle of this integrated shaft-type gearbox shaft system assembly tooling: During use, the tooling gear 130 is clamped into the keyway 122 of the motor rotor shaft 120 using the positioning key 131 for positioning. Then, the first shaft assembly 210 and the second shaft system assembly 220 are integrally placed into the lower housing 110. At this time, the teeth on the second gear 213 are clamped into the corresponding tooth grooves on the tooling gear 130. In this way, the second gear 213 can slide along the tooth grooves on the tooling gear 130 into the tooth grooves of the driving gear 121 for meshing. At the same time, the first rotating shaft 211 and the second rotating shaft 221 can smoothly enter the bearing grooves inside the lower housing 110 to complete the assembly. After the assembly is completed, the tooling gear 130 can be directly removed. In this way, gear collisions can be avoided during assembly, ensuring the quality of the gears. At the same time, the assembly can be simpler and more convenient, and is more conducive to automated operation.

[0028] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
