Description

Technical Field

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

[0002] In some linkage structures, gears are needed as transmission components to achieve the transmission effect on the target structural parts, and gears are generally mounted on gear shafts to perform the operation.

[0003] A search revealed CN222910705U, which discloses a synchronous gear shaft. The shaft comprises a gear shaft body with stripes on its outer side wall. Two symmetrical bearings are fitted onto the outer side wall of the gear shaft body. A synchronous pulley is installed between the two bearings and on the outer side wall of the gear shaft body. Baffles are installed on both sides of the synchronous pulley and on the outer side wall of the gear shaft body. This structure solves the slippage problem that occurs after the bearings and synchronous pulley are installed on the gear shaft. Furthermore, it limits the movement of the synchronous pulley to prevent it from deviating.

[0004] The aforementioned patents still have shortcomings in practical use. In the operation of existing technology, the gears can only work in a fixed position and cannot be used for the engagement and meshing of external gears in some offset positions, which limits the working range of the gears. In addition, after a long period of operation, the gears will inevitably suffer wear and tear, and usually the gears and gear shafts are replaced at the same time, which increases the replacement cost.

[0005] Based on this, this utility model discloses a novel gear shaft structure. Utility Model Content

[0006] To address the limitations of existing technologies, where gears can only operate in fixed positions and cannot engage with external gears at offset locations, thus restricting their operating range and causing inevitable wear after prolonged use (typically requiring replacement of both gears and gear shafts, increasing replacement costs), this invention provides a novel gear shaft structure. This structure includes a gear shaft body, with an adjustment component mounted at one end and a replacement component mounted at the other end. The adjustment component includes a moving groove. The moving grooves are symmetrically formed at one end of the gear shaft body, with one side of the moving groove located near the center of the gear shaft body. A rotating groove is provided at the position, and a screw is rotatably installed inside the rotating groove. One end of the screw is rotatably connected to the vertical inner wall of the rotating groove. A limiting shaft is fixedly connected inside the moving groove on the other side. A moving sleeve is fitted outside the cross-section of the gear shaft. A gear is fixedly connected outside the cross-section of the moving sleeve. Limiting blocks are symmetrically fixed on the arc surface of the inner wall of the moving sleeve. The two limiting blocks can move along the moving groove respectively. One limiting block is fitted outside the cross-section of the limiting shaft through a sliding hole, and the other limiting block is fitted outside the cross-section of the screw through a screw hole. A dial is installed inside the rotating groove, and the dial is fixedly fitted outside the cross-section of the screw.

[0007] As a further improvement to this technical solution, a first thread is provided around the end arc surface of the gear shaft with the moving groove, and an insertion hole is provided at the center of the vertical structural surface of the end of the gear shaft with the first thread. A locking cap is screwed to the outside of the gear shaft section at the location where the first thread is provided, and an insertion rod is fixed to the end of the locking cap away from the gear shaft. The insertion rod can be inserted into the interior of the insertion hole.

[0008] As a further improvement to this technical solution, the rotation trajectory of the actuating disc exceeds the cross-sectional range of the gear shaft, the working range of the locking cap can cover the opening range of the first thread, and when the locking cap completely covers the first thread, the ends of the limiting shaft and the moving sleeve are both inserted into the structural hole inside the moving groove.

[0009] As a further improvement to this technical solution, the replacement component includes an installation groove. The end of the gear shaft away from the moving groove is provided with an installation groove around the shaft body. An installation sleeve can be fitted on the arc surface of the installation groove. A second gear is fixedly fitted on the outside of the cross section of the installation sleeve.

[0010] As a further improvement to this technical solution, a limiting rod is fixed at an equal angle to the vertical inner wall surface of the opening end of the mounting groove, and limiting holes are opened at equal intervals on the cylindrical body of the mounting sleeve. The cross-sectional dimension of the limiting hole is slightly larger than the cross-sectional dimension of the limiting rod, and the length of the limiting rod is the same as the opening depth of the limiting hole.

[0011] As a further improvement to this technical solution, a second thread is provided on the arc surface of the mounting groove away from the gear shaft. A limiting sleeve is screwed into the mounting groove where the second thread is provided. When the limiting sleeve moves the farthest distance on the second thread, the limiting sleeve contacts the mounting sleeve, and the limiting rod is fully inserted into the limiting hole.

[0012] Compared with existing technologies, the beneficial effects of this utility model are:

[0013] 1. In this new gear shaft structure, the working position of the first gear can be adjusted by adjusting the working components, ensuring that the first gear can be adjusted according to the position of the external gear, ensuring that the first gear and the external gear always maintain sufficient contact area, expanding the working range of the gear transmission, and meeting the need for replacement.

[0014] 2. In this new gear shaft structure, the installation of the second gear is more stable through the cooperative operation of replacing components. At the same time, it is convenient to quickly replace the damaged second gear without having to replace the entire gear shaft, thus saving costs. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Therefore, this utility model provides a novel gear shaft structure, see [link to utility model]. Figures 1-4 As shown, it includes a gear shaft 1, an adjustment component installed at one end of the gear shaft 1, and a replacement component installed at the other end of the gear shaft 1. The adjustment component includes a moving groove 2. The moving groove 2 is symmetrically opened at one end of the shaft of the gear shaft 1. A rotating groove 3 is opened near the middle of the gear shaft 1 on one side of the moving groove 2. A screw 4 is rotatably installed inside the rotating groove 3 of the moving groove 2. One end of the screw 4 is rotatably connected to the vertical surface of the inner wall of the rotating groove 3. A limiting shaft 5 is fixedly connected inside the moving groove 2 on the other side. A moving sleeve 6 is fitted outside the cross section of the gear shaft 1. A first gear 7 is fixedly connected outside the cross section of the moving sleeve 6. Limiting blocks 8 are symmetrically fixed on the arc surface of the inner wall of the moving sleeve 6. The two limiting blocks 8 can move along the moving groove 2 respectively. One limiting block 8 is fitted outside the cross section of the limiting shaft 5 through a sliding hole. The other limiting block 8 is fitted outside the cross section of the screw 4 through a screw hole. A dial 9 is installed inside the rotating groove 3. The dial 9 is fixedly fitted outside the cross section of the screw 4. The inner arc surface of the movable sleeve 6 moves in contact with the outer arc surface of the gear shaft 1, applying a turning force to the dial 9. The screw 4 can rotate with the dial 9. The surface of the limiting block 8 is in contact with the inner wall of the movable groove 2, avoiding a large gap between the movable groove 2 and the limiting block 8, which would cause the limiting block 8 to deform during the rotation of the movable sleeve 6. This reduces the frequency of deformation of the limiting block 8 during the rotation of the first gear 7, and extends the service life of the first gear 7. The limiting block 8 drives the movable sleeve 6 and the first gear 7 to move, which can adjust the working position of the first gear 7.

[0023] A first thread 11 is formed around the arc surface of the end of the gear shaft 1 where the moving groove 2 is located. An insertion hole 10 is formed at the center of the vertical structural surface of the end of the gear shaft 1 where the first thread 11 is located. A locking cap 12 is screwed onto the outside of the gear shaft 1 at the location where the first thread 11 is located. An insertion rod 13 is fixed to the end of the locking cap 12 away from the gear shaft 1. The insertion rod 13 can be inserted into the insertion hole 10. The limiting effect of the insertion hole 10 and the insertion rod 13 ensures that the locking cap 12 gradually covers the first thread 11 along the axial direction of the gear shaft 1, making the rotation of the locking cap 12 smoother. At the same time, the first gear 7 can be replaced by removing the locking cap 12.

[0024] The rotation trajectory of the actuating disc 9 exceeds the cross-sectional area of ​​the gear shaft 1. The working range of the locking cap 12 can cover the opening range of the first thread 11. When the locking cap 12 completely covers the first thread 11, the ends of the screw 4 and the limiting shaft 5 are inserted into the structural holes inside the locking cap 12. The insertion of the screw 4 and the limiting shaft 5 into the structural holes of the locking cap 12 fixes the working position of the screw 4 and the limiting shaft 5, ensuring that the screw 4 and the limiting shaft 5 are not prone to bending or breaking when the gear shaft 1 transmits large torque for a long time.

[0025] During operation, by adjusting the structural design of the components, the limiting block 8 can be aligned with the opening of the moving slot 2. A pushing force is applied to the first gear 7, causing the moving sleeve 6 to be fitted onto the outside of the gear shaft 1. When the limiting block 8 moves the moving sleeve 6 and the first gear 7 to the threaded position of the screw 4, the locking cap 12 is rotatably installed on the first thread 11 using the limiting effect of the insertion hole 10 and the insertion rod 13. Subsequently, according to the position of the external gear, a rotational force is applied to the actuating disc 9. The actuating disc 9, under this force, causes the screw 4 to rotate. With the cooperation of the limiting shaft 5, the limiting block 8... The movable sleeve 6 and the first gear 7 move along the movable groove 2 to a suitable distance, thereby adjusting the working position of the first gear 7 and ensuring that the first gear 7 and the external gear always maintain sufficient contact area, thus improving the working range of the gear transmission. If the first gear 7, which has been in operation for a long time, needs to be replaced, a reverse turning force can be applied to the actuating disc 9 to move the limiting block 8 to move the movable sleeve 6 and the first gear 7 to the position of the locking cap 12. The locking cap 12 can then be removed by rotation, allowing the limiting block 8 to smoothly disengage from the inside of the movable groove 2, thus meeting the replacement requirement.

[0026] Further, see Figures 1-4 As shown, the replacement component includes a mounting groove 14. The end of the gear shaft 1 furthest from the moving groove 2 has a mounting groove 14 circumferentially formed around the shaft. A mounting sleeve 16 can be fitted onto the arc surface of the mounting groove 14. A second gear 17 is fixedly fitted onto the outer surface of the mounting sleeve 16. The length of the mounting groove 14 is greater than the length of the mounting sleeve 16, and the outer diameter of the mounting sleeve 16 is greater than the diameter of the gear shaft 1, facilitating the installation and fixation of the second gear 17.

[0027] Limiting rods 15 are fixed at equal angles to the vertical inner wall surface of the end of the mounting groove 14. Limiting holes 18 are equally spaced on the cylindrical body of the mounting sleeve 16. The cross-sectional dimensions of the limiting holes 18 are slightly larger than those of the limiting rods 15, and the length of the limiting rods 15 is the same as the opening depth of the limiting holes 18. The limiting effect of the limiting rods 15 and the limiting holes 18 ensures greater stability during the operation of the second gear 17.

[0028] A second thread 19 is formed on the arc surface of the mounting groove 14 away from the gear shaft 1. A limiting sleeve 20 is screwed to the position where the second thread 19 is formed in the mounting groove 14. When the limiting sleeve 20 moves the farthest distance on the second thread 19, the limiting sleeve 20 contacts the mounting sleeve 16, and the limiting rod 15 is fully inserted into the limiting hole 18. The limiting sleeve 20 can restrict the working position of the second gear 17 and also facilitates the subsequent individual replacement of the second gear 17.

[0029] During operation, by coordinating the replacement of components, when replacing the damaged No. 2 gear 17, a rotational force is applied to the limiting sleeve 20, causing the limiting sleeve 20 to disengage from the opening range of the mounting groove 14 through the second thread 19, thus removing the restriction on the mounting sleeve 16. Then, a pushing force is applied to the No. 2 gear 17, which drives the mounting sleeve 16 to move along the opening arc surface of the mounting groove 14. The limiting rod 15 gradually disengages from the limiting hole 18. After the limiting rod 15 is completely disengaged from the limiting hole 18, the mounting sleeve 16 and the No. 2 gear 17 can be removed from the shaft of the gear shaft 1, enabling quick replacement of the No. 2 gear 17. At the same time, it avoids replacing the undamaged gear shaft 1, saving costs.

[0030] In summary, this effectively solves the problems of existing technologies where gears can only operate in fixed positions and cannot be used to engage with external gears at offset positions, thus limiting the operating range of the gears. Furthermore, after prolonged operation, gears inevitably suffer wear and tear, usually requiring the replacement of both the gears and gear shafts, which increases replacement costs.
