The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so as to make the technical solutions of the present invention easier to understand and grasp.

As shown in fig. 1 to 3, a spinning gear shaft includes a main shaft body 1, a gear portion 2, a mounting portion 3, and a bearing 4. The spindle body 1 is used for mounting the gear portion 2 and the mounting portion 3. The gear part 2 is disposed on the spindle body 1 for meshing with gears of other mechanisms to realize transmission, and in the present embodiment, the gear part 2 is preferably disposed at one end of the spindle body 1. The mounting portion 3 is provided at the end of the other end of the main shaft body 1. The bearing 4 is mounted on the mounting portion 3. Thereby, the gear part 2 of the spinning gear shaft realizes the transmission function of the spinning gear shaft, and the rotation of the spinning gear shaft is more stable through the installation part 3.

With reference to fig. 2 and 3, the bearing 4 for a spinning gear shaft includes an inner housing 41, a mounting sleeve 42 and an outer housing 43. The inner housing 41 is fitted over one end of the spinning gear shaft, i.e. the above-mentioned mounting portion 3. The mounting sleeve 42 is sleeved on the inner shell 41. And the outer shell 43 is sleeved on the mounting sleeve 42. A plurality of groups of ball sets 44 are arranged in the mounting sleeve 42 along the axial direction thereof, the ball sets 44 include a plurality of balls 441, and the plurality of balls 441 surround the inner housing 41.

The bearings 4 mounted on the mounting portion 3 of the conventional spinning gear shaft normally provide a plurality of bearings 4 directly in the outer housing 43 for stable rotation of the spinning gear shaft. However, since the main shaft body 1, the mounting portion 3, and the bearings 4 have a certain machining error, a certain error may occur in the concentricity of the bearings 4 on the mounting portion 3, that is, the axes of the bearings 4 may not be on the same straight line, and the stable rotation of the spinning gear shaft may be affected.

In the bearing 4 of the present embodiment, the plurality of sets of ball groups 44 are disposed in the same mounting sleeve 42, so that one bearing 4 can also achieve the effect of a plurality of bearings 4, and one set of balls 44 can function as a common bearing 4. Meanwhile, because the plurality of ball groups 44 are all located in the same mounting sleeve 42, the variation of the machining error is reduced, and the concentricity between the plurality of ball groups 44 can be ensured only by keeping the machining error of the mounting sleeve 42 within a certain range, so that the axes of the plurality of ball groups 44 are located on the same straight line. Finally, the stable effect of the bearing 4 on the rotation of the main shaft body 1 is ensured.

As shown in fig. 3, the number of the ball sets 44 in this embodiment is preferably two, and the two ball sets are respectively located at the inner end and the outer end of the mounting sleeve 42, so as to simplify the structure of the bearing 4 while ensuring the stabilizing effect of the bearing 4 on the spindle body 1.

Further, as shown in fig. 3, the plurality of balls 441 in the ball group 44 are all located in the same radial plane of the mounting sleeve 42, and the planes of the plurality of ball groups 44 are parallel to each other. Thereby ensuring that the ball sets 44 are all perpendicular to the mounting portion 3 and the spindle body 1. Meanwhile, the plurality of ball groups 44 can be kept parallel, so that the positions of the ball groups 44 on the spindle body 1 can be uniformly stressed, and the stability of the rotation of the spindle body 1 is ensured.

Further, the balls 441 in each ball group 44 may be arranged in the mounting sleeve 42 in a circumferential array around the rotation axis of the main shaft body 1.

As shown in fig. 3, the balls 441 in the plurality of ball groups 44 are disposed correspondingly, and the plurality of balls 441 are linearly disposed on the axial section of the mounting sleeve 42. Thereby, the direction of the urging force of each ball 441 is further made uniform, and the stability of the bearing 4 is further improved.

As shown in fig. 3, a stop hoop 5 is disposed on the outer side of the inner housing 41, the stop hoop 5 is sleeved on the spinning gear shaft and abuts against the outer end face of the inner housing 41 for limiting the movement of the inner housing 41, and the bearing 4 is placed to be separated from the spindle body 1.

As shown in fig. 3, a first outer edge portion 431 is formed by extending the outer end of the outer shell 43, and a cap 6 is disposed on the first outer edge portion 431, and the cap 6 closes the outer end of the mounting portion 3, so as to protect the inner wall of the outer shell 43, the mounting sleeve 42 in the outer shell 43, the inner shell 41, the above-mentioned collar 5, and the like.

Further, with reference to fig. 2 and 3, the outer end of the spindle body 1 is provided with a step 11, the bearing 4 is disposed on the outer end face of the step 11, and the inner end of the inner housing 41 of the bearing 4 abuts against the outer end face of the step 11. The movement of the bearing 4 is thereby restricted by the interaction of the step 11 and the stop collar 5, so that the bearing 4 can only rotate on the mounting portion 3.

As shown in fig. 3, the inner end of the outer housing 43 extends outward to form a second outer edge portion 432, and a gap 7 exists between the second outer edge portion 432 and the peripheral surface of the spinning gear shaft, and in this embodiment, a gap 7 exists between the second outer edge portion 432 and the step portion 11, and the gap 7 may be provided with a gasket or other parts to protect the bearing 4, or may be empty to maintain the distance between the inner end of the bearing 4 and the step portion 11. Thereby, the inner end of the bearing 4 is not contacted with the main shaft body 1 of the spinning gear shaft, and the bearing 4 is prevented from being damaged by the rotation of the main shaft body 1.

In the present embodiment, it is preferable that the spindle body 1, the gear portion 2, and the mounting portion 3 are integrally molded.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
