DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0033] Referring to Figure 1 And Figure 2 An embodiment provided by the utility model: a sun gear dismounting tool, comprising shell one 1 and shell two 2, shell two 2 is internally provided with a dismounting assembly, and the dismounting assembly is used for quickly dismounting the sun gear.

[0034] The dismounting assembly comprises a rotating rod 3, the rotating rod 3 is slidably arranged in the shell two 2, the rotating rod 3 is movably arranged in the shell two 2 through a sliding support device, a rotating shaft 4 is threadedly connected to the outer wall of the rotating rod 3, so that the rotating rod 3 can stably slide during dismounting, the rotating rod 3 has high design precision, so that it can smoothly make necessary adjustment and positioning during dismounting operation, an anti-skid groove 5 is formed in the rotating shaft 4, so as to facilitate operation of an operator, a limiting groove 6 is formed in the rotating shaft 4, a limiting block 7 is fixedly connected to the upper surface of the shell one 1, the limiting block 7 is matched with the limiting groove 6, so that the movement range of the rotating shaft 4 in the shell is effectively limited, thereby avoiding structural damage or unnecessary wear caused by excessive rotation, a fixed shaft 8 is fixedly connected to one end of the rotating rod 3, a support rod 9 is rotatably connected to the inside of the fixed shaft 8, the support rod 9 is used for providing necessary supporting force during dismounting, thereby helping the operator to apply greater torque to the sun gear, an elastic washer 10 is fixedly connected to the inside of the fixed shaft 8, one end of the elastic washer 10 is fixedly connected to one side of the support rod 9, and the shell two 2 is provided with a dismounting assembly, so as to facilitate the operator to maintain the equipment.

[0035] Specifically, when there is a large interference between the sun gear and the cooperating components such as the shaft and the planet carrier, it means that the connection between them is very tight, and it needs to overcome a large friction and binding force to disassemble the sun gear. After the operator fits the device with the sun gear, the operator rotates the rotating shaft 4. At this time, the rotating action of the rotating shaft 4 is limited by the cooperation with the limiting block 7 and the limiting groove 6, so that the rotation of the rotating shaft 4 drives the rotating rod 3 to move up and down. When the rotating rod 3 goes down, it further drives the fixed shaft 8 and the support rod 9 to move synchronously. When the support rod 9 contacts the inner wall of the sun gear, it begins to generate a pressing action, pushing one side of the support rod 9 to rotate in the fixed shaft 8, so that the elastic gasket 10 deforms elastically. Due to its structural characteristics, the elastic gasket 10 will deform when subjected to pressure, so that the other side of the elastic gasket 10 deviates. When the rotating rod 3 continues to go down, the support rod 9 continuously applies pressure to the inner wall of the sun gear until the deformation of the elastic gasket 10 reaches the limit and pushes the support rod 9 to be clamped into the outer wall at the bottom end of the sun gear. At this time, since there is no extrusion force from the inner wall of the sun gear, the elastic gasket 10 will release its stored elastic potential energy, thereby pushing the support rod 9 to quickly clamp into the fixed position of the outer wall at the bottom end of the sun gear, completing the clamping action. Once the support rod 9 is completely clamped into the outer wall at the bottom end of the sun gear, the operator can continue to rotate the rotating shaft 4 to gradually lift the support rod 9, completing the process of disassembling the sun gear.

[0036] With reference to Figure 3 and Figure 4 , the disassembly assembly includes a fixed block one 11 and a fixed block two 12. The fixed block one 11 is fixedly connected to the outer wall of the shell two 2 on one side, serving to stabilize the entire assembly. The fixed block two 12 is fixedly connected to the outer wall of the shell one 1 on one side. The fixed block one 11 has a sliding column 13 slidingly connected inside, which can slide in the inner cavity of the fixed block one 11. This sliding connection allows the sliding column 13 to slide along the longitudinal direction of the fixed block one 11 during disassembly, thereby adjusting the position of the components to complete the disassembly action. The sliding column 13 has a limiting ring 14 slidingly connected to the outer wall, forming a stable constraint structure. The main function of the limiting ring 14 is to limit the sliding range of the sliding column 13 to prevent it from sliding excessively during operation, thereby ensuring the precision and safety of the assembly. The limiting ring 14 is fixedly connected to the inside of the fixed block one 11 on the outer wall. The sliding column 13 has a clamping block 16 fixedly connected to one end. The sliding column 13 has a spring one 15 sleeved on the outer wall. The spring one 15 provides a certain pushing force for the clamping block 16 to ensure that it can quickly return to the original position during disassembly, avoiding jamming caused by improper assembly. The spring one 15 is fixedly connected to one side of the limiting ring 14 on one end and to the upper surface of the clamping block 16 on the other end.

[0037] Specifically, in order to ensure the stable performance and service life of the inner support type dismounting tool, regular maintenance work needs to be carried out, which involves cleaning, lubricating, precision detection and other operations of each component inside the tool. During the operation of the device, the operator pushes the pull ring 18 to apply a certain pushing force. The pushing force of the pull ring 18 acts through the transmission column 17, so that it slides inside the fixed block two 12. This sliding action will cause the spring two 20 inside the fixed block two 12 to be elastically deformed, thereby storing a certain amount of energy to provide the necessary elastic force for the subsequent action. At the same time, the sliding of the fixed block two 12 not only affects the spring two 20, but also drives the curved ring 21 to move synchronously.

[0038] With reference to Figure 3 and Figure 4 , the transmission column 17 is slidably connected inside the fixed block two 12, which ensures that it can move freely within a certain range during operation. One end of the transmission column 17 is fixedly connected with the pull ring 18, which can be used for external operation so that the movement of the transmission column 17 can be transmitted to other mechanical systems. The outer wall of the transmission column 17 is slidably connected with the limiting shaft 19, which functions to limit the sliding range of the transmission column 17 to avoid exceeding the predetermined stroke. The limiting shaft 19 is sleeved with the spring two 20 outside the wall, which can provide certain elastic support for the limiting shaft 19 to ensure that the transmission column 17 is uniformly stressed during sliding to avoid violent impact or unnecessary vibration. One end of the spring two 20 is fixedly connected with one side of the limiting shaft 19, and the other end is in contact with the inner wall of the fixed block two 12. The outer wall of the transmission column 17 is slidably connected with the curved ring 21, which is tightly matched with the outer wall of the transmission column 17 but does not produce excessive friction, thereby reducing energy loss. The outer wall of the transmission column 17 is provided with the spring three 22, one end of which is in contact with the curved ring 21, and the other end is fixedly connected with the limiting ball 23.

[0039] Specifically, the curved surface ring 21 has a unique smooth curved surface structure, which can stably contact the clamping block 16. When the curved surface ring 21 contacts the clamping block 16, due to the smooth curved surface effect on both sides of the curved surface ring 21, the friction between the contact surfaces is small, reducing the resistance in motion. At this time, the interaction between the curved surface ring 21 and the clamping block 16 further promotes the elastic deformation of the spring three 22. The deformation of the spring three 22 plays a limiting and guiding role, making the subsequent action more accurate and controllable. As the curved surface ring 21 continues to slide to the other side of the clamping block 16, the extrusion force of the curved surface ring 21 gradually increases. This force pushes the clamping block 16 upwards. The upward movement of the clamping block 16 drives the sliding column 13 to slide slightly inside the limiting ring 14. The limiting ring 14 provides position limitation to ensure that the sliding column 13 maintains the appropriate position during operation, preventing excessive movement or misalignment. Finally, the cooperation between the curved surface ring 21 and the clamping block 16 drives the displacement of the sliding column 13, achieving the purpose of quick disassembly and maintenance, allowing the operator to conveniently and quickly complete the disassembly and maintenance of the equipment, ensuring the normal operation and service life of the equipment.

[0040] Working principle: When using the device, the operator makes the device fit with the sun gear, then rotates the rotating shaft 4. When the rotating shaft 4 rotates, the limiting block 7 and the limiting groove 6 cooperate to limit the rotation of the rotating shaft 4, which drives the rotating rod 3 to move downward and upward. When the rotating rod 3 moves downward, it further drives the fixed shaft 8 and the support rod 9 to move synchronously. When the support rod 9 contacts the inner wall of the sun gear, it will generate a pressing force to drive one side of the support rod 9 to rotate inside the fixed shaft 8, causing the elastic gasket 10 to elastically deform, thereby causing the other side to deviate. When reaching the bottom end of the sun gear, the elastic gasket 10 releases its elastic potential energy to push the support rod 9 to be clamped into the outer wall of the bottom end of the sun gear. The operator rotates the rotating shaft 4 to drive the support rod 9 to rise, thereby achieving the effect of disassembling the sun gear. When the equipment needs to be disassembled and maintained, the operator pushes the pull ring 18, which further drives the transmission column 17 to slide inside the fixed block two 12. The sliding of the fixed block two 12 drives the spring two 20 to elastically deform, and at the same time, the curved surface ring 21 moves synchronously. When the curved surface ring 21 contacts the clamping block 16, due to the smooth curved surface on both sides of the curved surface ring 21, the contact with the clamping block 16 further drives the spring three 22 to elastically deform. When the curved surface ring 21 slides to the other side of the clamping block 16, the extrusion force of the curved surface ring 21 drives the clamping block 16 to move upward, thereby further driving the sliding column 13 to slide slightly inside the limiting ring 14, thereby achieving the effect of quick disassembly and maintenance.

[0041] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, the made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
