[0002] The sun gear is the basic component of the epicyclic gear system. In the planetary gear system, the outer gear that serves as the central gear is called the sun gear. In the planetary gear transmission, the outer gear and the inner gear on the same axis as the planet carrier are called the sun gear. The sun gear transmission is the most widely used mechanical transmission in modern mechanical products because it can ensure a constant transmission ratio and has the advantages of a large transmission power range, high efficiency and long life.

[0023] See also Figure 1-Figure 4 , a sun gear processing tool, comprising: a fixed frame 1, a rotating rod 2 installed above the fixed frame 1 through a bearing, a driving motor 3 connected to one side of the rotating rod 2, a rolling gear 4, a first synchronous wheel 5, a meshing belt 6, a second synchronous wheel 7, a cross bar 8, a first bevel gear 9, a second bevel gear 10, a transmission rod 11, a synchronous pulley assembly 12, a vertical rod 13, a supporting plate 14, a threaded block 15, a limit plate 16, a gear plate 17, a rotating rod 18, a slide plate 19, a sleeve shaft 20 and a threaded rod 21, and further comprising: the rotating rod 2 is driven by the driving motor 3, so that the rotating rod 2 is convenient for rotating above the fixed frame 1, and at the same time, a rolling gear 4 is fixedly connected to one end of the rotating rod 2, so that the rotating rod 2 can synchronously drive the rolling gear 4 to rotate, and the other end of the rolling gear 4 is rotatably connected to the fixed frame 1 through a bearing, so that the stability of the rotation of the rolling gear 4 is achieved, and the rolling gear effect of the rolling gear 4 on the sun gear is ensured;

[0024] Further, considering the rotation effect of the sun gear during gear hobbing production, a cross bar 8 is transmission-connected below the rotating rod 2, and the cross bar 8 is distributed in parallel with the rotating rod 2. Specifically, a first synchronous wheel 5 is fixedly connected to the outer wall of the rotating rod 2, and a meshing belt 6 is meshedly connected to the outer wall of the first synchronous wheel 5, and a second synchronous wheel 7 is meshedly connected to the inner wall of the bottom end of the meshing belt 6. At the same time, the second synchronous wheel 7 is fixedly connected to the outer wall of the cross bar 8, and the cross bar 8 is installed below the fixed frame 1 through a bearing. Through such an arrangement, the rotating rod 2 can realize the stable transmission of the cross bar 8 below, ensuring the synchronization of the rotation of the cross bar 8.

[0025] In order to realize the transmission between the cross bar 8 and the sun gear, a transmission rod 11 is connected to one side of the cross bar 8 through a bevel gear set, and the transmission rod 11 is vertically distributed with the cross bar 8, which is convenient for changing direction transmission. Specifically, a first bevel gear 9 is fixedly connected to one end of the cross bar 8, and a second bevel gear 10 is meshed and connected to the top of the first bevel gear 9. The second bevel gear 10 is fixedly installed at the bottom end of the transmission rod 11, and the transmission rod 11 is rotatably arranged at the bottom of the fixed frame 1 through a bearing. Through such an arrangement, the transmission rod 11 can be realized when the rotating rod 2 rotates. At the same time, a vertical rod 13 is also connected to one side of the transmission rod 11, and the vertical rod 13 is distributed in parallel with the transmission rod 11. In order to achieve stable transmission of the parallel transmission rod 11 and the vertical rod 13, the outer wall of the transmission rod 11 is connected to the vertical rod 13 through the synchronous pulley assembly 12, which is convenient for stable transmission through the synchronous pulley assembly 12. The vertical rod 13 is arranged on one side of the central axis of the roller gear 4, and the vertical rod 13 is penetrated on the surface of the fixed frame 1 through the bearing, which ensures the rotation effect of the vertical rod 13 on the surface of the fixed frame 1.

[0026] See also Figure 1 In order to achieve stable limiting of the sun gear above the vertical rod 13, a support plate 14 is fixedly connected to the outer wall of the vertical rod 13, and the support plate 14 is arranged in a circular structure with the vertical rod 13 as the center, which is convenient for the sun gear to be placed on the surface of the support plate 14, and the sun gear is flexibly sleeved on the outer wall of the vertical rod 13, and a threaded block 15 is threadedly connected to the upper outer wall of the vertical rod 13, and a limiting plate 16 is fixedly connected to the outer wall of the threaded block 15, and the limiting plate 16 is distributed in parallel with the support plate 14. Through such an arrangement, the user can adjust the height of the limiting plate 16 through the threaded block 15, which is convenient for the limiting plate 16 to be pressed on the surface of the sun gear, and the limiting plate 16 and the upper and lower surfaces of the support plate 14 are clamped on the sun gear, so that the vertical rod 13 drives the sun gear to rotate stably;

[0027] See also Figure 1-Figure 4In order to accurately detect the red teeth of the sun gear after gear hobbing, a gear plate 17 is provided on the side of the support plate 14 away from the hobbing gear 4, so that the gear plate 17 is meshed with one side of the sun gear for rotation, and considering the rotation effect of the gear plate 17, the gear plate 17 is fixedly connected to the top of the rotating rod 18, and the rotating rod 18 is rotatably arranged on the surface of the slide plate 19 through the bearing, thereby ensuring the flexibility of the rotation of the gear plate 17, and in order to achieve the looseness adjustment of the meshing effect with the sun gear, the slide plate 19 is telescopically adjusted on the surface of the fixed frame 1. Specifically, the slide plate 19 is arranged in a horizontal "L"-shaped structure, and a threaded rod 21 is connected to the lower side of the slide plate 19 through a sleeve shaft 20, and the threaded rod 21 is threadedly connected to the fixed frame 1, so that the user can adjust the position of the slide plate 19 by rotating the threaded rod 21, and it is convenient to adjust the distance of the gear plate 17 on one side of the sun gear through the slide plate 19, which is conducive to improving the working range of the fixture and enhancing the applicability.

[0028] Working principle: When in use, the sun gear is sleeved on the outer wall of the vertical rod 13, so that the sun gear is placed on the surface of the supporting plate 14, and the threaded block 15 is rotated, so that the threaded block 15 drives the limit plate 16 to move downward, so that the limit plate 16 is pressed on the surface of the sun gear, and the sun gear is fixed on the outer wall of the vertical rod 13 through the supporting plate 14 and the limit plate 16. After the sun gear is fixed, it is driven by the driving motor 3, so that the rotating rod 2 drives the rolling gear 4 to rotate, so that the rolling gear 4 rotates the surface of the sun gear. At the same time, by arranging the first synchronous wheel 5 on the outer wall of the rotating rod 2, under the action of the meshing belt 6, the second synchronous wheel 7 synchronously drives the transverse The rod 8 rotates, and the first bevel gear 9 is fixedly connected to one end of the cross rod 8. Under the meshing action of the first bevel gear 9 and the second bevel gear 10, the transmission rod 11 rotates, and through the setting of the synchronous pulley assembly 12, the vertical rod 13 drives the sun gear on the surface to rotate, so that the sun gear rotates and opens teeth on one side of the rolling gear 4 in sequence, and by setting a gear plate 17 on one side of the sun gear, the teeth of the sun gear after opening can be meshed through the transmission detection effect of the gear plate 17, and by the movable setting of the slide plate 19 on the surface of the fixed frame 1, the user can flexibly adjust the position of the gear plate 17, thereby ensuring the accuracy of the sun gear tooth detection.
