[0002] The gear machine spindle refers to the main bearing component used to transmit power and rotational motion. The gear hobbing machine spindle plays a key role in the work of the gear hobbing machine. The spindle is usually supported by bearings to ensure its stable rotational motion. In the gear hobbing machine, the rotation speed and accuracy of the spindle are crucial to the quality and accuracy of the processed gears.

[0003] In the existing technology, as time goes by, the spindle will be worn out after continuous use. However, when replacing it, because there are many bolts fixing the spindle, these bolts need to be removed and installed one by one. This will increase the workload and time of replacing the spindle, especially when the bolt position is narrow or difficult to access. Each removal and installation of the bolts has potential risks, such as misoperation, damage to the thread or tightening errors, etc., and it will increase the complexity of the system and increase the troubleshooting and debugging time during the replacement process.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1 - Figure 5As shown, the utility model provides a technical solution: a direct-connected spindle of a gear hobbing machine, comprising: a replacement mechanism 1, an auxiliary mechanism 2 is arranged on the outside of the replacement mechanism 1, the replacement mechanism 1 comprises a motor 11, a connecting frame 12 is arranged at one end of the motor 11, a spindle body 112 is arranged on the inner surface of the connecting frame 12, a semicircular rod 13 is arranged on the bottom side of the spindle body 112, a flower-shaped ring 15 is arranged on the outside of one end of the semicircular rod 13, an embedded frame 16 is arranged on the outside of the flower-shaped ring 15, a side plate 18 is arranged on the outside of the embedded frame 16, a slide plate 19 is arranged at one end of the top of the side plate 18, a sleeve 110 is arranged inside the slide plate 19, a bolt 111 is arranged inside the sleeve 110, a connecting frame 12 is arranged at one end of the sleeve 110, one end of the motor 11 is fixedly connected to one side of the connecting frame 12, and the inner surface of the connecting frame 12 is connected to the outer side of the spindle body 112 The bottom side of the main shaft body 112 and the outer side of the semicircular rod 13 are mutually clamped, the outer side of one end of the semicircular rod 13 is fixedly connected to the inner ring of the bearing 14, the outer ring of the bearing 14 is fixedly connected to the inner wall of one side of the connecting frame 12, the outer side of one end of the bearing 14 is fixedly connected to the inner wall of the flower-shaped ring 15, the outer side of the flower-shaped ring 15 and the inner surface of the embedded frame 16 are mutually clamped, the outer side of the embedded frame 16 is rotatably connected to the inner wall of the side plate 18, one side of the embedded frame 16 is fixedly connected to one end of the connecting rod 17, the outer side of the connecting rod 17 is in contact with the inner wall of the side plate 18, the top inner part of the side plate 18 is slidably connected to the outer side of the sleeve 110, the inner part of the sleeve 110 is slidably connected to the inner part of the slide plate 19, the inner part of the sleeve 110 is in contact with the outer side of the bolt 111, the outer side of the bolt 111 is threadedly connected to the inner part of the slide plate 19, and one side of the slide plate 19 is in contact with one side of the side plate 18.

[0027] In this embodiment, when the staff is using the spindle, the spindle will be worn due to long-term use. Therefore, when replacing it, the bolt 111 is removed from the slide plate 19 and separated from the sleeve 110, so that the side plate 18 is released, and then the side plate 18 is pulled to one side, so that the embedded frame 16 gradually separates from the flower ring 15, and the corresponding fixation is released by several different components, so that the semicircular rod 13 is no longer restricted. At this time, the semicircular rod 13 is rotated 180 degrees, so that the semicircular rod 13 is no longer clamped to the spindle body 112, and the original fixed state connected with the spindle body 112 is released, so that the spindle body 112 can move freely. By releasing the fixation, the original spindle can be replaced. The replacement of the spindle is to repair wear or failure, or upgrade to a spindle with higher performance;

[0028] Secondly, during installation, the main shaft body 112 is placed in the connecting frame 12, and then the semicircular rod 13 is rotated 180 degrees to fix it again. Currently, only preliminary fixation is required. At this time, the embedded frame 16 in the side panel 18 is adjusted to correspond to the groove of the flower-shaped ring 15, and then the two are engaged along the corresponding points to fix the flower-shaped ring 15 on the semicircular rod 13 to ensure the stable installation of the main shaft body 112. Finally, the slide plate 19 is moved on the sleeve 110 to make it close to the side panel 18, and then the bolt 111 is extended into the sleeve 110 and rotated to make the slide plate 19 threadedly connected. The side panel 18 is clamped with the cooperation of the bolt 111 and the slide plate 19, thereby avoiding accidents when the main shaft body 112 is in use.

[0029] Example 2

[0030] like Figure 1 - Figure 2 As shown, the auxiliary mechanism 2 includes a protective shell 21, the upper and lower sides of the protective shell 21 are mutually engaged with one end of two plug plates 22, and one end of the two plug plates 22 is slidingly connected to one end of the motor 11, and one end of the motor 11 is in contact with one end of the protective shell 21.

[0031] In this embodiment, the installed protective shell 21 is outside the connection frame 12. Since there are many components on the connection frame 12, the protective shell 21 can provide physical isolation and protection to prevent people from accidentally touching or accidentally contacting components on the connection frame 12, which helps to ensure the safety of operators and reduce potential risks and the possibility of accidents. It can also provide an additional layer of protection to protect the connection frame 12 from damage or pollution from the external environment, which can extend the service life of the connection frame 12 and reduce maintenance requirements. Finally, the plug board 22 is moved down so that one end of it is clamped on the protective shell 21, and the protective shell 21 is preliminarily fixed. The two are finally fixed by screws, which reduces the movement and vibration of the internal components of the connection frame 12, which helps to reduce damage to the connection frame 12 caused by vibration and impact, and improves the durability of the connection frame 12.

[0032] Working principle:

[0033] like Figure 1 - Figure 5As shown, when the utility model is used, according to the needs of the user, the bolt 111 is removed from the slide plate 19 and separated from the sleeve 110, so that the side plate 18 is released, and then the side plate 18 is pulled to one side, so that the embedded frame 16 is gradually separated from the flower-shaped ring 15, and the corresponding fixation is released by several different components, so that the semicircular rod 13 is no longer restricted. At this time, the semicircular rod 13 is rotated 180 degrees, so that the semicircular rod 13 is no longer clamped to the main shaft body 112, and the original fixed state connected with the main shaft body 112 is released, so that the main shaft body 112 can move freely. By releasing the fixation, the original main shaft can be replaced;

[0034] The protective shell 21 is installed on the outside of the connection frame 12 to prevent people from accidentally touching or contacting components on the connection frame 12, reduce potential risks and the possibility of accidents, and provide an additional layer of protection to protect the connection frame 12 from damage or contamination from the external environment.
