[0002] In a mechanical transmission system, a gear shaft is a common rotating component used to transmit torque and rotational speed. To ensure the stability and reliability of the transmission system, it is necessary to prevent the bearings and synchronous pulleys on the gear shaft from slipping during operation. At the same time, it is also necessary to limit the synchronous pulley to prevent it from running off track. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a synchronous gear shaft, which solves the problem of slipping of the bearings and synchronous pulleys after they are installed on the gear shaft. In addition, the synchronous pulley is limited to prevent it from running off track.

[0004] The utility model also provides a synchronous gear shaft as described above, including: a gear shaft body, wherein the outer side wall of the gear shaft body is provided with stripes, two symmetrically arranged bearings are sleeved on the outer side wall of the gear shaft body, a synchronous pulley is installed on the outer side wall of the gear shaft body between the two bearings, and baffles are installed on the outer side wall of the gear shaft body on both sides of the synchronous pulley.

[0005] According to the synchronous gear shaft described above, the number of the stripes is six, and the six stripes are symmetrically distributed along the axial direction of the gear shaft body on the outer side wall of the gear shaft body.

[0006] According to the synchronous gear shaft described above, the baffles and the bearings have the same radius size, and the baffles are located between the two bearings.

[0007] According to the synchronous gear shaft described above, the inner walls of the bearings, the synchronous pulley and the baffles are all adapted to the stripes.

[0008] The utility model has the following beneficial effects:

[0009] 1. In the utility model, the stripes effectively prevent the bearings and the synchronous pulley from slipping, ensuring the stability and reliability of the transmission system.

[0010] 2. In the utility model, the baffles prevent the synchronous pulley from running off track during operation, ensuring the normal operation of the transmission system and the transmission efficiency of the synchronous pulley.

[0018] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The role of the accompanying drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0019] Refer to Figures 1-3 , an embodiment of a synchronous gear shaft of the present utility model includes: a gear shaft body 1, a stripe 2 is provided on the outer side wall of the gear shaft body 1, the number of the stripes 2 is six, and the six stripes 2 are symmetrically distributed along the axial direction of the gear shaft body 1 on the outer side wall of the gear shaft body 1. The inner walls of the bearing 3, the synchronous pulley 4 and the baffle 5 are all adapted to the stripe 2. Two symmetrically arranged bearings 3 are sleeved on the outer side wall of the gear shaft body 1. A synchronous pulley 4 is installed on the outer side wall of the gear shaft body 1 between the two bearings 3. Baffles 5 are installed on the outer side wall of the gear shaft body 1 on both sides of the synchronous pulley 4. The baffle 5 and the bearing 3 have the same radius size, and the baffle 5 is located between the two bearings 3. Through the above structure, the problem of slipping after the bearing 3 and the synchronous pulley 4 are installed on the gear shaft is solved. In addition, the synchronous pulley 4 is limited to prevent the synchronous pulley 4 from running off.

[0020] Working principle: When the gear shaft body 1 rotates, the stripe 2 ensures sufficient friction between the bearing 3, the synchronous pulley 4 and the baffle 5 and the gear shaft body 1 to prevent slipping. The bearing 3 provides stable rotational support, while the baffle 5 ensures the correct position of the synchronous pulley 4 to prevent running off, so as to achieve precise power transmission and synchronous movement.
