The gear shaft is usually made of metal material and has a certain strength and wear resistance after processing and heat treatment. The gear shaft is usually manufactured by a forging process, which is called shaft forging.

[0003] The patent application with publication number CN204628245U discloses a gear shaft forging, aiming to provide a low-cost, high-strength, non-deformable gear shaft forging. The key points of its technical solution are that it includes a gear shaft body forged from 20CrMnTi material, and is characterized in that: the gear shaft body includes an integrally arranged flange portion, a left shaft portion and a right shaft portion, the left shaft portion and the right shaft portion are respectively located on the left and right sides of the flange portion, the left shaft portion includes a left large cylindrical section, a left middle cylindrical section, and a left small cylindrical section with an outer diameter that is decreasing, the right shaft portion includes a right large cylindrical section and a right small cylindrical section with an outer diameter that is decreasing, and the right large cylindrical section is provided with an annular groove.

[0004] In this public patent, the length of the gear shaft is fixed and cannot be flexibly adjusted according to different usage requirements. Each size of gear shaft can only be suitable for one usage requirement, resulting in low flexibility in the use of the gear shaft.

[0005] In summary, the utility model provides a gear shaft forging to solve the above problems. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the present utility model is to provide a gear shaft forging, which has the advantage that, through the threaded connection between the threaded sleeve and the mounting shaft section, the length of the gear shaft body can be flexibly adjusted according to the gear installation requirements, which is suitable for a variety of usage requirements and effectively improves the flexibility of use of the gear drawer.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A gear shaft forging comprises a main shaft body and an installation shaft section, wherein both ends of the main shaft body are provided with a receiving groove, the inner surface of the receiving groove is provided with two guide grooves, a guide seat is slidably installed between the two guide grooves, both ends of the main shaft body are provided with annular installation grooves, a threaded sleeve is rotatably installed inside the annular installation groove, and the outer surface of the installation shaft section is provided with a threaded groove.

[0009] By adopting the above technical solution, the guide groove is used to guide the sliding direction of the guide seat, thereby preventing the installation shaft section from driving the guide seat to rotate together when the threaded sleeve rotates.

[0010] The utility model is further configured as follows: the installation shaft section is arranged inside the threaded sleeve.

[0011] By adopting the above technical solution, the thread groove and the internal thread of the threaded sleeve are connected. When the threaded sleeve rotates, it is pulled and restricted by the guide seat and the guide groove, and the installation shaft section can realize telescopic movement in the receiving groove.

[0012] The utility model is further configured as follows: one end of the installation shaft section is fixedly connected to one side of the guide seat.

[0013] By adopting the above technical solution, the extension length of the mounting shaft section changes as the threaded sleeve rotates, thereby changing the overall length of the gear shaft body and increasing the scope of application.

[0014] The utility model is further configured as follows: two fixing rings are fixedly mounted on the outer surface of the main shaft body.

[0015] By adopting the above technical solution, the two fixing rings are close to the two ends of the main shaft body, and after being connected with the anti-shift screw, the threaded sleeve can be limited.

[0016] The utility model is further configured as follows: a plurality of stabilizing holes are provided inside the fixing ring.

[0017] By adopting the above technical solution, the stabilizing holes are evenly distributed on the fixing ring, and after the threaded sleeve is rotated, the anti-shifting screw will rotate to the corresponding positions of the stabilizing holes at different positions.

[0018] The utility model is further configured as follows: a support seat is fixedly installed on one side of the threaded sleeve.

[0019] By adopting the above technical solution, the outer surface of the threaded sleeve is provided with anti-skid grooves, which increase the friction with the hand and prevent slipping when rotating the threaded sleeve.

[0020] The utility model is further configured as follows: an anti-movement screw is installed on the inner thread of the support seat.

[0021] By adopting the above technical solution, the anti-movement screw is restricted in the position of the threaded sleeve by the stabilizing hole.

[0022] In summary, the beneficial technical effects of the utility model are:

[0023] By rotating the threaded sleeve, the installation shaft section can achieve telescopic movement under the guide limit of the guide seat and the guide groove. Moving the installation shaft section out increases the length of the gear shaft body, and moving the installation shaft section in reduces the length of the gear shaft body. The length of the gear shaft body can be flexibly adjusted according to the gear installation requirements. It is suitable for various usage requirements and effectively improves the flexibility of the gear extractor.
