Technical Field
[0001] This utility model relates to the field of gear transmission components technology, specifically to a modular transmission frame with quick gear replacement. Background Technology
[0002] In mechanical transmission systems, a large number of gears are required for transmission. As the equipment operates, the gears gradually wear down due to meshing, friction, and collisions, requiring periodic replacement. However, existing transmission frame installation methods mostly use multi-bolt installation or one-time riveting installation. After riveting installation, the gears cannot be directly replaced; the entire gear frame and gear set must be replaced, which is costly. Alternatively, the connecting rod can be cut, the gears replaced, and then welded together, which is cumbersome and inefficient. Bolt installation requires loosening and tightening the bolts sequentially during disassembly and assembly, which is also quite cumbersome. Utility Model Content

Frame 1 is also provided with multiple connecting support seats, each of which is provided with a connecting support rod. Frame 2 is provided with multiple connecting female seats below, each of which has a groove. The front end of the connecting support rod matches the shape of the groove and is inserted into the groove. Frame 2 has a through hole, and the connecting support seats have holes with the same shape as the through hole. The front end of each connecting support rod is connected to a connector, which passes through the through hole. Frame 2 is provided with a rotary snap-fit assembly for positioning the connector. Frame 2 is also provided with a cover plate.
[0005] Preferably, the rotary snap-fit assembly includes a rotary groove opening above the second frame body, an annular movable snap ring is provided in the rotary groove, multiple snap grooves are opened in the movable snap ring, the connector passes through the through hole and the snap grooves, and a snap-fit groove with the same shape as one end of the snap groove is opened on one side of the connector.
[0006] Preferably, one end of the slot is a semi-circle that matches the shape of the connector, and the other end is a right-angled side.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figures 1 to 2 As shown, the device consists of two main annular components, namely frame 1 and frame 2. Frame 1 is provided with multiple gear shafts 4, while frame 2 is provided with multiple gear shafts 6. The front end of gear shaft 4 is provided with alignment hole 5, and the front end of gear shaft 6 is connected to alignment head 7. By inserting alignment head 7 into alignment hole 5, a gear shaft for installing gears is formed. The frame 1 is provided with multiple connecting support seats 8, and each connecting support seat 8 is provided with a connecting support rod 9; the frame 2 is provided with multiple connecting female seats 21 below, and each connecting female seat 21 has a groove. The front end of the connecting support rod 9 matches the shape of these grooves and can be smoothly inserted into them. The second frame 2 also has a through hole 13, and the connecting support base 8 has a hole with the same hole as the through hole 13. The front end of the connecting support rod 9 is connected to a connector 10, which passes through the through hole 13. A rotary snap-fit assembly is provided on the top of the second frame 2 to position the connector 10. A cover plate 3 is also installed on the top of the second frame 2. Multiple annular magnetic rings 17 are embedded on the upper side of the second frame 2, while multiple magnetic rings 18 are embedded on the lower side of the cover plate 3. The two are fixed to the second frame 2 by magnetic attraction.
[0018] See Figures 1 to 6 The rotary snap-fit assembly includes a rotary groove 12 opened on the upper part of the frame 2; a circular movable snap ring 14 is provided in the rotary groove 12, the surface of the snap ring 14 is provided with multiple sets of anti-slip textures 16, and multiple snap grooves 15 are opened in the snap ring 14; the connector 10 is provided through the through hole 13 and the snap groove 15, and one side of the connector 10 is provided with a snap-fit groove 11 with the same shape as one end of the snap groove 15; One end of the slot 15 is a semi-circle that matches the side shape of the connector 10, and the other end is a right-angled side. The snap-fit groove 11 has the same shape as one side of the right-angled side. The cover plate 3 has multiple limiting protrusions 19 on its lower side. When the movable snap ring 14 rotates, the end of the slot 15 is inserted into the snap-fit groove 11 and fits tightly against its inner wall. At this time, the shape of the limiting protrusion 19 matches the exposed part of the slot 15, and the limiting protrusion 19 is inserted into the slot 15 for positioning. On the cover plate 3, a limiting slot 20 is also provided on the side of each limiting protrusion 19; when the limiting protrusion 19 is inserted into the slot 15, the top of the connector 10 will be inserted into the limiting slot 20 for further auxiliary positioning.
[0019] During installation, align frame 1 and frame 2, place the gears, and then assemble them. At this time, the end of connector 10 extends out of through hole 13. Place movable retaining ring 14 into rotating groove 12, then press down on anti-slip texture 16 and rotate movable retaining ring 14 so that it is inserted into snap-fit groove 11 through slot 15, axially positioning connector 10 and connecting the two frames. Then, align the limiting protrusion 19 below cover plate 3 with slot 15 and cover it. Under magnetic force, it will automatically be attracted and installed. Limiting protrusion 19 is inserted into slot 15, and connector 10 is inserted into limiting slot 20, thereby angularly positioning movable retaining ring 14 and preventing accidental rotation. When the gear needs to be replaced, lift the cover plate 3 upwards, then rotate the movable retaining ring 14 in the opposite direction, and then the frame body 1 and frame body 2 can be separated to replace the gear.
