Description

Technical Field

[0001] This utility model relates to the field of gear technology, and more specifically, to a sun gear that is not easily dislodged from its shaft. Background Technology

[0002] The sun gear is the basic component of a planetary gear system, and in a planetary gear system, the outer gear that serves as the central gear is called the sun gear.

[0003] For example, existing patent CN207726420U discloses a sun wheel for a paperboard line or printing press. The wheel body is securely fixed to the printing press shaft through a fixing groove on a hollow cylindrical surface, while a spiral groove axially penetrates the wheel body, effectively reducing its weight. The spiral groove is composed of a first arc edge, a second arc edge, a third arc edge, and a fourth arc edge, enhancing air convection and increasing the rubber content, making the sun wheel more wear-resistant and heat-resistant, ensuring long-term paper feeding and meeting production requirements. However, the fixing groove on the circumference of the hollow cylindrical surface prevents the sun wheel from detaching from the shaft during operation. This design requires a corresponding change to the shaft, fixing the shaft circumference with a locking block that matches the fixing groove to achieve the above effect. This necessitates replacing the entire existing shaft in the printing plant, increasing replacement costs.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a sun gear that is not easy to detach from the shaft, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A sun gear that is not easily detached from its axis includes a sun gear body one and a sun gear body two, as well as a connecting mechanism for connecting the sun gear body one and the sun gear body two;

[0008] The connecting mechanism includes a connecting column, one end of which is connected to one side of the sun gear body. The sun gear body has a through hole for the connecting column to pass through. The connecting column has a limiting hole at the through hole. A limiting block adapted to the limiting hole is movably connected inside the connecting column.

[0009] Preferably, a lead screw is rotatably connected inside the connecting column, and a matching sleeve is fitted on the lead screw. A connecting piece extending outside the connecting column is provided around the outer wall of the sleeve. An inclined movable rod is movably connected to the top of the connecting piece, and the other end of the movable rod is movably connected to the limiting block.

[0010] Preferably, the outer wall of the connecting column is surrounded by a fixing plate corresponding to the connecting piece. A second movable rod is movably connected to the fixing plate and is arranged to cross the first movable rod. A movable shaft is movably connected at the intersection of the second movable rod and the first movable rod. The other end of the second movable rod is slidably connected to the limiting block.

[0011] Preferably, the limiting block is provided with a limiting slide for the sliding shaft to move.

[0012] Preferably, one end of the lead screw extends to the outside of the connecting post and is provided with a knob.

[0013] Preferably, the connecting post has a travel hole for the connecting piece to move.

[0014] Preferably, a chamfer is provided at the intersection of the limiting hole and the first and second sun gear bodies.

[0015] The beneficial effects of this utility model are as follows: when the sun gear body one and the sun gear body two are installed on the rotating shaft, the connecting column on the sun gear body one passes through the through hole and the limiting hole in sequence. The position of the limiting block corresponds to the position of the limiting hole and moves outward to complete the limiting function, so that the sun gear body one and the sun gear body two rotate as a whole, and there will be no situation where a single sun gear body is detached from the shaft, which would cause the direction of paper conveying to deviate.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a sun gear that is not easily detached from its shaft is provided.

[0026] Example 1:

[0027] like Figure 1-5 As shown, the sun gear that is not easily detached from the shaft according to an embodiment of the present utility model includes a sun gear body 1 and a sun gear body 2, as well as a connecting mechanism for connecting the sun gear body 1 and the sun gear body 2.

[0028] The connecting mechanism includes a connecting post 3, one end of which is connected to the side of the sun gear body 1. The sun gear body 2 has a through hole 4 for the connecting post 3 to pass through. The connecting post 3 has a limiting hole 5 at the through hole 4. A limiting block 6 that matches the limiting hole 5 is movably connected inside the connecting post 3.

[0029] Example 2:

[0030] like Figure 1-5As shown, a lead screw 7 is rotatably connected inside the connecting column 3. A matching sleeve 8 is fitted on the lead screw 7. A connecting piece 9 extending outside the connecting column 3 is arranged around the outer wall of the sleeve 8. An inclined movable rod 10 is movably connected to the top of the connecting piece 9. The other end of the movable rod 10 is movably connected to the limiting block 6. A fixing piece 11 corresponding to the connecting piece 9 is arranged around the outer wall of the connecting column 3. A movable rod 2 12 arranged crosswise with the movable rod 10 is movably connected to the fixing piece 11. A movable shaft 13 is movably connected at the intersection of the movable rod 2 12 and the movable rod 10. The other end of the movable rod 2 12 is slidably connected to the limiting block 6.

[0031] Example 3:

[0032] like Figure 1-5 As shown, the limiting block 6 has a limiting slide for the sliding shaft 14 to move, one end of the lead screw 7 extends to the outside of the connecting post 3 and has a knob 15, the connecting post 3 has a stroke hole for the connecting piece 9 to move, and the limiting hole 5 has a chamfer at the intersection with the sun gear body 1 and the sun gear body 2.

[0033] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0034] In practical applications, when installing the sun gear body 1 and the sun gear body 2 onto the rotating shaft, the connecting post 3 on the sun gear body 1 passes through the through hole 4 and the limiting hole 5 in sequence. The position of the limiting block 6 corresponds to the position of the limiting hole 5. Then, the knob 15 is turned to drive the lead screw 7 to rotate. The sleeve 8 moves to the right as the lead screw 7 rotates. During the movement, the sleeve 8 presses the movable rod 10 through the connecting piece 9, causing the movable rod 10 and the movable rod 2 12 to rotate around the movable shaft 13 as the pivot point. This pushes the limiting block 6 to move outward and abut against the limiting hole 5, thus completing the limiting function. This ensures that the sun gear body 1 and the sun gear body 2 rotate as a whole, preventing a single sun gear body from detaching from the shaft and causing a deviation in the direction of paper transmission.

[0035] In summary, with the help of the above-mentioned technical solution of this utility model, when the sun gear body 1 and the sun gear body 2 are installed on the rotating shaft, the connecting post 3 on the sun gear body 1 passes through the through hole 4 and the limiting hole 5 in sequence. The position of the limiting block 6 corresponds to the position of the limiting hole 5 and moves outward to complete the limiting function. This makes the sun gear body 1 and the sun gear body 2 rotate as a whole, and prevents a single sun gear body from detaching from the shaft, which would cause a deviation in the direction of paper transmission.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
