Description

Technical Field

[0001] This utility model relates to the field of transmission components technology, and in particular to a high-efficiency interchangeable gear. Background Technology

[0002] A gear is a mechanical component used to transmit power and change the speed and direction of motion, and is widely used in various mechanical devices. It transmits and converts power through the meshing of teeth. Gears are typically made of steel, cast iron, or plastic, and their design and manufacturing precision directly affect their performance and service life. Gears play a crucial role in mechanical design, ensuring the efficient and stable operation of equipment.

[0003] The current gears do not have a disassembly mechanism for the teeth, which means that the teeth cannot be replaced when they are worn, and the entire compound gear must be replaced when replacement is needed.

[0004] Therefore, it is necessary to add replaceable teeth to reduce the cost incurred when the teeth of the current gears wear out. For example, a composite gear with easy replacement of worn parts is proposed in application number CN202421624398.1. Its technical features include a mounting plate and a connecting shaft. A sliding groove is evenly opened on one side of the mounting plate. A slider is slidably connected inside the sliding groove. A tooth block is fixedly installed on the side of the slider away from the sliding groove. A connecting sleeve is threaded inside the mounting plate. A limiting plate is fixedly installed on the outer wall of the connecting sleeve. A fixing plate is symmetrically fixedly installed on the side of the limiting plate away from the connecting sleeve.

[0005] The above technical solution, by setting up a slide groove, a slider, a connecting sleeve, a limiting plate, and a fixing plate, allows the fixing plate to rotate, causing the limiting plate to rotate. During the rotation of the limiting plate, the connecting sleeve rotates inside the mounting plate. After rotating a certain number of times, the connecting sleeve and the limiting plate can be removed. After removal, the worn tooth block is pushed, causing it to slide inside the slide groove. After sliding a certain distance, the worn tooth block and the slider can be removed and replaced. This effectively avoids the need to replace the entire compound gear after the tooth block wears out.

[0006] However, since the connecting sleeve and the mounting plate are connected by threads, the gear must rotate in the opposite direction to the threads of the connecting sleeve and the mounting plate after it is connected to the gear shaft. Otherwise, the connecting sleeve and the mounting plate may separate. Therefore, the structure of the gear needs to be improved to avoid the problem of the connecting sleeve and the mounting plate separating.

[0007] Therefore, a highly efficient gear replacement method is proposed to solve or alleviate the above problems. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient gear replacement method.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A high-efficiency gear replacement includes a gear disk, several gear blocks, and a limiting disk. The outer ring of one side of the gear disk has several narrowed grooves, and the gear blocks are slidably connected in the narrowed grooves. The inner ring of the limiting disk is fixedly connected to a connecting cylinder that can be embedded into the inner ring of the gear disk. The end of the connecting cylinder away from the limiting disk is fixedly connected to a limiting cylinder that can be embedded into the inner ring of the gear disk. A limiting structure is provided between the limiting cylinder and the gear disk, and the limiting structure restricts relative rotation between the limiting cylinder and the gear disk.

[0011] Preferably, one side of the inner ring of the gear disc is recessed inward to form a groove, and the other side of the gear disc has a through groove coaxially connected to the groove. The connecting cylinder is embedded in the groove, and the limiting cylinder is embedded in the through groove.

[0012] Preferably, the inner ring of the through groove has a plurality of obliquely inserted grooves arranged in a ring array and inclined toward the opening of the through groove, the inner ring of the limiting cylinder has an oblique through hole communicating with the obliquely inserted grooves, the limiting structure is embedded in the obliquely inserted grooves and the oblique through hole, and the limiting cylinder has a limiting post detachably connected to prevent the limiting structure from leaving the oblique through hole.

[0013] Preferably, the inner ring of the limiting cylinder has an internal thread, the outer ring of the limiting post has an external thread, and the oblique through hole and the limiting post are connected by the internal thread and the external thread.

[0014] Preferably, the limiting structure includes an insert post that can be embedded in the oblique groove, and a connecting post fixedly connected to the end of the insert post, wherein the length of the connecting post and the insert post is less than the sum of the groove depths of the oblique groove and the oblique through hole.

[0015] Preferably, the outer ring of the connecting post has a connecting hole through which it passes.

[0016] Preferably, the end of the limiting post away from the groove has a polygonal groove.

[0017] This utility model has the following beneficial effects:

[0018] During assembly, the toothed block is embedded in the constricted groove, and the connecting cylinder and limiting cylinder are inserted into the inner ring of the gear disc, so that the limiting cylinder is embedded in the through groove and the connecting cylinder is embedded in the recess, with the oblique through hole aligned with the oblique groove. An inclined insert is inserted into the oblique groove, and the connecting cylinder is embedded in the oblique through hole. The limiting cylinder, connected by a thread, restricts reverse displacement, pushing the limiting cylinder against the limiting cylinder. The gear shaft is then inserted to complete the assembly. If the toothed block is damaged, the gear shaft is disassembled, the polygonal groove is tapped to retract the insert and connecting cylinder, and the limiting cylinder is removed before replacing the toothed block. The gear rotation direction does not affect the structure, preventing the limiting disc from detaching from the gear disc. Attached Figure Description

[0031] A high-efficiency interchangeable gear, such as Figures 1 to 4 As shown, the device includes a gear disk 1, several gear blocks 3, and a limiting disk 4. Several constricted grooves 2 are provided on the outer ring of one side of the gear disk 1. The gear blocks 3 are slidably connected in the constricted grooves 2. A connecting cylinder 5 that can be embedded into the inner ring of the gear disk 1 is fixedly connected to the inner ring of the limiting disk 4. A limiting cylinder 6 that can be embedded into the inner ring of the gear disk 1 is fixedly connected to the end of the connecting cylinder 5 away from the limiting disk 4. A limiting structure is provided between the limiting cylinder 6 and the gear disk 1. The limiting structure restricts the relative rotation between the limiting cylinder 6 and the gear disk 1.

[0032] One side of the inner ring of the gear disk 1 is recessed to form a groove 8. The other side of the gear disk 1 has a through groove 9 that is coaxially connected with the groove 8. The connecting cylinder 5 is embedded in the groove 8, and the limiting cylinder 6 is embedded in the through groove 9. The inner ring of the through groove 9 has several obliquely inserted grooves 10 arranged in a ring array and inclined towards the opening of the through groove 9. The inner ring of the limiting cylinder 6 has an oblique through hole 7 that is connected to the obliquely inserted groove 10. The limiting structure is embedded in the obliquely inserted groove 10 and the oblique through hole 7. The limiting cylinder 6 has a detachable limiting post 14 that prevents the limiting structure from leaving the oblique through hole 7. The inner ring of the limiting cylinder 6 has an internal thread, and the outer ring of the limiting post 14 has an external thread. The oblique through hole 7 and the limiting post 14 are connected by the internal thread and the external thread.

[0033] The limiting structure includes a post 11 that can be embedded in the oblique groove 10, and a connecting post 12 fixedly connected to the end of the post 11. The length of the connecting post 12 and the post 11 is less than the sum of the groove depths of the oblique groove 10 and the oblique through hole 7. The outer ring of the connecting post 12 is provided with a connecting hole 13 that passes through it. The end of the limiting post 14 away from the groove 8 is provided with a polygonal groove 15.

[0034] In actual assembly, this invention requires several toothed blocks 3 to be embedded into various constricted grooves 2. Then, connecting cylinders 5 and limiting cylinders 6 are inserted into the inner ring of the toothed disc 1, allowing the limiting cylinder 6 to embed into the through groove 9 and the connecting cylinder 5 into the recess 8. The oblique through hole 7 on the limiting cylinder 6 must be aligned with the oblique insertion groove 10 on the inner ring of the through groove 9. Next, the insert post 11 is tilted and aligned with the oblique through hole 7, allowing it to be inserted into the oblique insertion groove 10, and the connecting post 12 to be embedded into the oblique through hole 7. Finally, the limiting post 14 is connected to the inner thread of the inner ring of the limiting cylinder 6 via an external thread, thereby limiting the reverse displacement of the connecting post 12 and the insert post 11. This also allows the connecting post 12 to push the external thread of the limiting post 14 to abut against the internal thread of the inner ring of the limiting cylinder 6, making them difficult to separate. Then, simply insert the gear shaft into the connecting cylinder 5 for connection to complete the gear assembly. If a single tooth block 3 is damaged, simply remove the gear shaft and then use a hammer to strike the inner wall of the polygonal groove 15 so that the insert post 11 and the connecting post 12 can return to the oblique insert groove 10 and oblique through groove 9. Then, disassemble the limiting post 14 through the polygonal groove 15 and then perform the assembly action in reverse to complete the disassembly and replacement of the tooth block 3, ultimately obtaining a complete gear. The rotation direction of the gear will not affect its structure, preventing the limiting plate 4 from detaching from the tooth plate 1.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
