Description

Technical Field

[0001] This utility model relates to the field of gear shaft technology, specifically a combined gear shaft. Background Technology

[0002] A gear shaft is a mechanical component primarily used to support rotating parts and rotate with them to transmit motion, torque, or bending moment. It is typically a round metal rod, with different diameters for each section. Gear shafts play a crucial role in mechanical transmission systems, especially when it is necessary to transmit power and adjust rotational speed.

[0003] In the prior art, gear shafts are usually one piece. When the gear and shaft are made as one piece, the problem of insufficient strength caused by key connection can be avoided. However, this design increases manufacturing costs. In particular, when one tooth of the gear is damaged, the entire gear shaft needs to be replaced instead of just the gear, which further increases maintenance costs.

[0004] Therefore, a combined gear shaft is provided to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a combined gear shaft to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a combined gear shaft, including a drive shaft body, a positioning plate installed on the outer surface of the drive shaft body, a gear installed on the outer surface of the drive shaft body, one side of the gear abutting against the positioning plate, a receiving groove opened at one end of the drive shaft body, a sliding groove opened inside the receiving groove, the number of the sliding grooves is fixed to four, a fixing mechanism is installed inside the receiving groove, and a limiting mechanism is installed inside the receiving groove.

[0008] Furthermore, the surface of the gear is provided with fixing grooves, and the number of fixing grooves is fixed at four.

[0009] Furthermore, the fixing mechanism includes movable rods and auxiliary insert rods, and the number of movable rods is fixed at four sets, with the four sets of movable rods slidably connected to the slide groove.

[0010] Furthermore, each of the four sets of movable rods has an auxiliary insert rod installed at one end, and the four sets of auxiliary insert rods penetrate the drive shaft body and are inserted into the fixing groove.

[0011] Furthermore, the limiting mechanism includes a fixing screw, a limiting threaded sleeve, and a hexagonal disassembly hole, and the fixing screw is installed inside the receiving groove.

[0012] Furthermore, the outer surface of the fixing screw is threadedly connected to a limiting threaded sleeve, the circumferential side of the limiting threaded sleeve abuts against one end of the four sets of auxiliary inserts, and the outer surface of the limiting threaded sleeve is provided with a hexagonal disassembly hole.

[0013] This utility model has the following beneficial effects:

[0014] (1) By inserting a hexagonal tool into the hexagonal disassembly hole and loosening the limiting threaded sleeve, the limiting of the auxiliary rod is released. Then the auxiliary rod is pulled out from the fixing groove, and the gear can be removed from the drive shaft body for individual replacement. This avoids the situation where the entire gear shaft needs to be replaced if the gear is damaged individually, thus reducing maintenance costs.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 As shown, this utility model is a combined gear shaft, including a drive shaft body 1, a positioning plate 2 installed on the outer surface of the drive shaft body 1, a gear 3 installed on the outer surface of the drive shaft body 1, one side of the gear 3 abutting against the positioning plate 2, a receiving groove 101 opened at one end of the drive shaft body 1, a sliding groove 102 opened inside the receiving groove 101, the number of sliding grooves 102 is fixed to four, a fixing mechanism is installed inside the receiving groove 101, and a limiting mechanism is installed inside the receiving groove 101.

[0025] The surface of gear 3 is provided with a fixing groove 301, and the number of fixing grooves 301 is fixed to four.

[0026] The fixing mechanism includes movable rod 4 and auxiliary insertion rod 5. The number of movable rod 4 is fixed at four sets, and the four sets of movable rod 4 are slidably connected to the slide groove 102.

[0027] Each of the four sets of movable rods 4 has an auxiliary rod 5 installed at one end. The four sets of auxiliary rods 5 pass through the drive shaft body 1 and are inserted into the fixed groove 301.

[0028] The limiting mechanism includes a fixing screw 6, a limiting threaded sleeve 7, and a hexagonal disassembly hole 701. The fixing screw 6 is installed inside the receiving groove 101.

[0029] The outer surface of the fixing screw 6 is threadedly connected to the limiting thread sleeve 7. The peripheral side of the limiting thread sleeve 7 abuts against one end of the four sets of auxiliary insert rods 5. The outer surface of the limiting thread sleeve 7 is provided with a hexagonal disassembly hole 701.

[0030] When assembling the gear shaft, the gear 3 is fitted onto the drive shaft body 1, with one side of the gear 3 abutting against the positioning plate 2. The positioning plate 2 serves to initially position the gear 3, determining its axial position on the drive shaft body 1. The four sets of movable rods 4 can slide in the sliding grooves 102 within the receiving grooves 101 of the drive shaft body 1. After the gear 3 is installed in place, the four sets of movable rods 4 are pushed, causing the auxiliary inserts 5 at one end of each set of movable rods 4 to pass through the drive shaft body 1 and insert into the fixing grooves 301 on the inner surface of the gear 3. Through the insertion of the auxiliary inserts 5 into the fixing grooves 301, the gear 3 is fixed radially, preventing radial rotation of the gear 3 on the drive shaft body 1. Then, the limiting threaded sleeve 7 is threaded onto... The outer surface of the fixing screw 6 is connected to one end of the four sets of auxiliary rods 5 by the peripheral side of the limiting threaded sleeve 7. When the limiting threaded sleeve 7 is tightened, it will limit the four sets of auxiliary rods 5, making the auxiliary rods 5 more securely inserted into the fixing groove 301. This completes the installation and use of the gear 3. When the gear 3 is damaged, a hexagonal tool can be inserted into the hexagonal disassembly hole 701 to loosen the limiting threaded sleeve 7, release the limitation on the auxiliary rods 5, and then pull the auxiliary rods 5 out of the fixing groove 301. This allows the gear 3 to be removed from the drive shaft body 1 for individual replacement, avoiding the need to replace the entire gear shaft when the gear 3 is damaged alone, thus reducing maintenance costs.

[0031] In use, when assembling the gear shaft, first, place the gear 3 onto the drive shaft body 1, so that one side of the gear 3 abuts against the positioning plate 2. The positioning plate 2 serves to initially position the gear 3, determining its axial position on the drive shaft body 1. The four sets of movable rods 4 can slide in the sliding grooves 102 within the receiving grooves 101 of the drive shaft body 1. After the gear 3 is installed in place, push the four sets of movable rods 4 so that the auxiliary inserts 5 at one end of the four sets of movable rods 4 pass through the drive shaft body 1 and are inserted into the fixing grooves 301 on the inner surface of the gear 3. Through the insertion of the auxiliary inserts 5 into the fixing grooves 301, the gear 3 is fixed radially, preventing the gear 3 from rotating radially on the drive shaft body 1. Then, thread the limiting threaded sleeve 7. Connected to the outer surface of the fixing screw 6, the peripheral side of the limiting threaded sleeve 7 abuts against one end of the four sets of auxiliary rods 5. When the limiting threaded sleeve 7 is tightened, it will limit the four sets of auxiliary rods 5, making the auxiliary rods 5 more securely inserted into the fixing groove 301, thus completing the installation and use of the gear 3. When the gear 3 is damaged, a hexagonal tool can be inserted into the hexagonal disassembly hole 701 to loosen the limiting threaded sleeve 7, release the limitation on the auxiliary rods 5, and then pull the auxiliary rods 5 out of the fixing groove 301. The gear 3 can then be removed from the drive shaft body 1 for individual replacement, avoiding the need to replace the entire gear shaft when the gear 3 is damaged alone, thus reducing maintenance costs.
