Description

Technical Field

[0001] This utility model relates to the field of gear technology, specifically to a gear assembly with adjustable gear meshing pitch. Background Technology

[0002] Gears are mechanical components with teeth on their rims that can continuously mesh to transmit motion and power. Gears have been used in transmission for a long time. With the emergence of the principle of gear generating and cutting and the special machine tools and cutting tools that use this principle for gear cutting, the smoothness of gear operation has become a focus as production has developed.

[0003] According to a gear assembly with adjustable gear meshing clearance disclosed in the above application (Announcement No.: CN219994366 U), adjusting the meshing clearance between the driving gear and the driven gear can effectively fine-tune the meshing clearance between the gears according to actual needs.

[0004] However, in actual use, the meshing clearance of some gears is relatively fixed after they are fixed, which leads to inaccurate meshing and defects in gear transmission efficiency, affecting the transmission between gears. In view of this, we propose a gear assembly with adjustable gear meshing distance. Summary of the Invention

[0005] The purpose of this invention is to provide a gear assembly with adjustable gear meshing distance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gear assembly with adjustable gear meshing distance, comprising a mounting platform, a mounting seat disposed on the outer side of the mounting platform, a motor fixedly mounted on the inner wall of the mounting seat, the output end of the motor being fixedly connected to a main gear via a round rod, a driven gear disposed on the outer side of the main gear, an adjustment mechanism disposed on the outer side of the mounting platform, and a facilitating mechanism disposed on the outer side of the mounting platform, the adjustment mechanism comprising:

[0007] A sliding groove is formed on the side wall of the mounting platform. A fixing block is detachably connected to the side wall of the mounting platform by bolts. A lead screw is rotatably connected to the side wall of the fixing block. A worm gear is fixedly installed at the end of the lead screw.

[0008] A fixing plate is fixedly installed on the side wall of the mounting platform. A worm gear is rotatably connected to the side wall of the fixing plate. A sliding block is fixedly installed on the side of the mounting base away from the main gear.

[0009] Preferably, the promoting mechanism includes a moving groove, which is formed on the side wall of the mounting platform. A connecting seat is fixedly installed on the lower surface of the mounting base, and a connecting rod is rotatably connected to the arc surface of the connecting seat. A moving block is provided inside the moving groove.

[0010] Preferably, there are two movable blocks, which are connected by a connecting rod, thereby supporting the mounting base.

[0011] Preferably, the shape of the moving groove is adapted to the shape of the moving block, and the shape of the sliding groove is adapted to the shape of the sliding block, so that the moving block can move inside the moving groove, and the sliding block can move inside the sliding groove.

[0012] Preferably, there are two fixed plates, and the worm gear passes through one of the fixed plates and is rotatably connected to the side wall of the other fixed plate, thereby enabling the worm gear to rotate stably.

[0013] Preferably, a rotating disk is fixedly installed at the end of the worm gear, and the rotating disk facilitates the adjustment of the worm gear's rotation.

[0014] Preferably, the side wall of the mounting base is provided with a groove, which facilitates the placement of the motor and thus ensures the stability of the main gear rotation.

[0015] Compared with the prior art, the present invention provides a gear assembly with adjustable gear meshing pitch, which has the following advantages:

[0016] 1. This adjustable gear meshing distance gear assembly is equipped with an adjustment mechanism. Adjusting the worm gear causes the worm wheel to rotate, which in turn causes the lead screw to rotate, driving the mounting base to move horizontally and thus moving the main gear. This adjusts the distance between the main gear and the driven gear. The self-locking characteristic of the worm wheel and worm gear ensures the stability of the mounting base. The sliding block and sliding groove further stabilize the mounting base, ensuring the stability of the distance between the main gear and the driven gear after adjustment.

[0017] 2. The adjustable gear meshing pitch gear assembly is equipped with a facilitating mechanism. The connecting seat on the mounting base, together with the connecting rod, allows the moving block to slide inside the moving groove, thereby ensuring the support of the connecting rod for the mounting base, further promoting the stability of the mounting base, reducing the impact of gear transmission vibration on the mounting base, and ensuring the stability of the gear transmission after adjustment.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a gear assembly with adjustable gear meshing distance, including a mounting platform 1, a mounting seat 2 on the outer side of the mounting platform 1, a motor 5 fixedly mounted on the inner wall of the mounting seat 2, the output end of the motor 5 being fixedly connected to a main gear 6 via a round rod, a driven gear 7 on the outer side of the main gear 6, an adjustment mechanism 3 on the outer side of the mounting platform 1, and a facilitating mechanism 4 on the outer side of the mounting platform 1. The adjustment mechanism 3 includes a sliding groove 301, a fixing block 302, a lead screw 303, a worm gear 304, a fixing plate 305, a worm 306, and a sliding block 307.

[0024] In one embodiment of this utility model, a sliding groove 301 is formed on the side wall of the mounting platform 1. A fixing block 302 is detachably connected to the side wall of the mounting platform 1 by bolts. A lead screw 303 is rotatably connected to the side wall of the fixing block 302. A worm gear 304 is fixedly installed at the end of the lead screw 303. A fixing plate 305 is fixedly installed on the side wall of the mounting platform 1. A worm gear 306 is rotatably connected to the side wall of the fixing plate 305. A sliding block 307 is fixedly installed on the side of the mounting seat 2 away from the main gear 6.

[0025] Additionally, the facilitating mechanism 4 includes a moving groove 401, which is formed on the side wall of the mounting platform 1. A connecting seat 403 is fixedly installed on the lower surface of the mounting base 2. A connecting rod 404 is rotatably connected to the arc surface of the connecting seat 403. A moving block 402 is provided inside the moving groove 401. There are two moving blocks 402, which are connected by the connecting rod 404. The connecting rod 404 supports the mounting base 2. The shape of the moving groove 401 is adapted to the shape of the moving block 402. The shape of the sliding groove 301 is adapted to the shape of the sliding block 307. Thus, the moving block 402 can move inside the moving groove 401, and the sliding block 307 can move inside the sliding groove 301. There are two connecting seats 403. One connecting seat 403 is fixedly installed on the lower surface of the mounting base 2, and the other connecting seat 403 is fixedly installed on the side wall of the moving block 402.

[0026] In this embodiment of the invention, two fixing plates 305 are provided. A worm gear 306 passes through one of the fixing plates 305 and is rotatably connected to the side wall of the other fixing plate 305, thereby enabling the worm gear 306 to rotate stably. Similarly, two fixing blocks 302 are provided. A lead screw 303 passes through one of the fixing blocks 302 and is rotatably connected to the side wall of the other fixing block 302, ensuring the stable rotation of the lead screw 303. A rotating disk is fixedly installed at the end of the worm gear 306. The rotating disk facilitates the adjustment of the rotation of the worm gear 306. A groove is provided on the side wall of the mounting base 2. The groove facilitates the placement of the motor 5, thereby ensuring the stability of the rotation of the main gear 6. The arc surface of the lead screw 303 is slidably connected to the mounting base 2. The mounting base 2 can slide on the surface of the lead screw 303. The transmission between the lead screw 303 and the mounting base 2 is achieved through the meshing of threads. The lead screw 303 has external threads, and the sliding mounting base 2 has matching internal threads. When the lead screw 303 rotates, another component moves along the axial direction of the lead screw 303. This transmission method is similar to the fit of a nut and a bolt. The arc-shaped thread of the lead screw 303 is connected to the inner wall of the mounting base 2. The sliding block 307 is fixedly installed on the side wall of the mounting base 2. The shaft of the gear 7 is fixed to the corresponding outer structure to ensure the overall transmission of the gear.

[0027] In this invention, during use, adjusting the worm 306 causes the worm wheel 304 to rotate, which in turn causes the lead screw 303 to rotate, driving the mounting base 2 to move horizontally and thus the main gear 6 to move. Adjusting the distance between the main gear 6 and the driven gear 7, combined with the self-locking characteristics of the worm wheel 304 and worm 306, ensures the stability of the mounting base 2. The sliding block 307 and sliding groove 301 further stabilize the mounting base 2, ensuring the stability of the distance between the main gear 6 and the driven gear 7 after adjustment.

[0028] Furthermore, the connecting seat 403 on the mounting base 2, in conjunction with the connecting rod 404, allows the moving block 402 to slide inside the moving groove 401, thereby ensuring the support of the connecting rod 404 for the mounting base 2, further promoting the stability of the mounting base 2, reducing the impact of gear transmission vibration on the mounting base 2, and ensuring the stability of the gear transmission after adjustment.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
