Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] In this embodiment, refer to Figure 1 - Figure 5 The specific implementation of the planetary carrier output shaft includes a shaft body 1 and several gears 2. One end of the shaft body 1 is provided with several through slots 11 around the axis. Several gears 2 are detachably installed in several through slots 11 through quick-release components 3. The other end of the shaft body 1 is provided with a connecting rod 12.

[0018] In this embodiment, there are three gears 2 and three through slots 11. The three gears 2 are evenly distributed along the circumference of the shaft 1, and the three gears 2 are evenly spaced. This makes the force on the planetary carrier output shaft more uniform during operation, reducing vibration and wear, and improving transmission efficiency and service life. The three gears 2 are respectively engaged with the through slots 11 on the shaft 1 through quick-release components 3, thereby realizing quick assembly and disassembly of the gears 2, improving assembly efficiency and maintenance convenience.

[0019] The quick-release assembly 3 includes a fixing rod 31, a fixing sleeve 32, and a sliding sleeve 33. The fixing sleeve 32 is provided with a fixing block 34 that cooperates with the fixing rod 31 and the sliding sleeve 33. The fixing rod 31 is provided with a fixing groove 311 that cooperates with the fixing block 34. One end of the sliding sleeve 33 is provided with a return spring 35 that cooperates with the fixing sleeve 32.

[0020] The fixing sleeve 32 is fixedly installed on one side of the through groove 11 by a threaded fit. One end of the fixing sleeve 32 has several locking holes. During use, the fixing sleeve 32 is firmly fixed to the shaft 1 by engaging the locking holes with a tool, preventing it from loosening or falling off during operation. The fixing rod 31 passes through the gear 2 from the other side of the through groove 11 and engages with the fixing block 34 inside the fixing sleeve 32. The fixing block 34 is slidably installed inside the fixing sleeve 32. The sliding sleeve 33 is located on the outside of the fixing sleeve 32 and is elastically connected to the fixing sleeve 32 by a return spring 35, thereby pressing the fixing block 34 to achieve a locking function.

[0021] When gear 2 needs to be installed, place gear 2 into the through slot 11. Then, push the sliding sleeve 33 to release the fixing block 34, and pass the fixing rod 31 through gear 2 and insert it into the fixing sleeve 32. Then release the sliding sleeve 33, causing the return spring 35 to push the sliding sleeve 33 back to its original position. During the back-reset process, the sliding sleeve 33 presses the fixing block 34, causing it to engage in the fixing groove 311 on the fixing rod 31, thereby locking the fixing rod 31 and achieving quick fixing of gear 2. When gear 2 needs to be disassembled, simply push the sliding sleeve 33 again to disengage the fixing block 34 from the fixing groove 311, and the fixing rod 31 can be pulled out, thereby releasing gear 2 and achieving quick disassembly of gear 2.

[0022] The sliding sleeve 33 is provided with a guide portion 331 that cooperates with the fixed block 34. The guide portion 331 allows the sliding sleeve 33 to smoothly push the fixed block 34 to slide. The fixed block 34 has a spherical or rounded-end rectangular cross-section. The shape of the fixing groove 311 matches the spherical surface of the fixed block 34, ensuring that the fixed block 34 can be stably embedded in the fixing groove 311 in the locked state and smoothly disengage from the fixing groove 311 in the released state, thus avoiding jamming. Both the spherical and rounded-end rectangular structures can reduce the frictional resistance between the fixed groove 311 and the sliding sleeve 33, making the locking and unlocking operations smoother. In this embodiment, the fixed block 34 adopts a spherical structure with a smooth surface to further reduce the coefficient of friction and improve the smoothness of operation.

[0023] One end of the shaft 1 is provided with an open groove 13, and a lever 36 that cooperates with the sliding sleeve 33 is slidably installed in the open groove 13. One end of the lever 36 is inserted into the open groove 13 and connected to the sliding sleeve 33, so that the sliding lever 36 can drive the sliding sleeve 33 to slide, thereby realizing the unlocking and locking operation of the fixed block 34.

[0024] In this embodiment, the cross-section of the toggle block 36 is a Z-shaped structure. The Z-shaped structure has good bending resistance, which can effectively prevent the toggle block 36 from bending and deforming during operation, thereby ensuring the stability and reliability of the unlocking and locking actions.

[0025] Gear 2 has a sleeve 21 that mates with quick-release assembly 3. A bearing 22 is located between sleeve 21 and gear 2. One end of sleeve 21 has a locking block 23 for fixing bearing 22. Sleeve 21 and fixing rod 31 are fitted with a clearance fit, which ensures that gear 2 maintains good coaxiality and stability when rotating, while allowing fixing rod 31 to be smoothly inserted into or removed from sleeve 21, thereby realizing quick assembly and disassembly of gear 2. Bearing 22 is fixed between gear 2 and sleeve 21 through the cooperation of locking block 23 and sleeve 21.

[0026] When gear 2 becomes worn or needs replacement, push the sliding sleeve 33 to disengage the fixing block 34 from the fixing groove 311 and pull out the fixing rod 31. Then, remove gear 2 and the sleeve 21, and insert the pre-prepared replacement gear 2 and sleeve 21 assembly into the through groove 11. The replacement gear 2 is then quickly secured using the cooperation of the fixing rod 31 and the fixing block 34. This achieves efficient replacement of gear 2. The entire disassembly and assembly process requires no additional tools and can be completed manually, improving maintenance efficiency, reducing operational difficulty, and minimizing equipment downtime.

[0027] Subsequently, maintenance personnel can repair or replace the disassembled old gear 2 and related components, storing them as spare parts or recycling them, thereby improving resource utilization. This, in turn, saves resources, reduces waste, and lowers operating costs.

[0028] The connecting rod 12 is provided with a keyway 14 for external connection. During use, different sized key blocks are installed on the keyway 14 according to the application requirements. When high torque transmission is required, spline or tangential key blocks are selected to increase transmission stability and load-bearing capacity; when lower torque requirements are required, flat or semi-circular keys can be used to simplify the structure and reduce costs. Through the selection and combination of various key blocks, the transmission needs under different working conditions can be flexibly adapted, thereby improving the overall applicability and economy of the equipment.

[0029] The beneficial effects of this utility model are as follows: The quick-release assembly 3 allows the gear 2 to be installed in the through slot 11 on the shaft 1, thus enabling rapid assembly and disassembly of the gear 2, improving assembly efficiency and maintenance convenience, thereby reducing maintenance time and improving equipment operating efficiency. Furthermore, the connecting rod 12, in conjunction with an external drive component, achieves efficient power transmission and stable output.
