Description

Technical Field

[0001] The present invention relates to the technical field of gear transmission, and specifically relates to a multi-stage transmission composite gear. Background Technique

[0002] A multi-stage transmission composite gear is an efficient and precise mechanical transmission device, which is composed of multiple gear segments. Through a composite structure, it realizes power transmission and speed change functions. Its design makes full use of the gear meshing principle and can achieve multiple transmission ratios in a compact space. It is widely used in industrial machinery, automobiles, aerospace and other fields. The remarkable features of the composite gear are high transmission efficiency, strong load-bearing capacity, stable operation and low noise, and it can also meet the power requirements under complex working conditions.

[0003] The patent application with the application number CN202320781176.X discloses a composite gear, which includes a gear body and a connection disk detachably connected to the gear body. At least four opening grooves are formed on one side of the connection disk. A moving rod is vertically slidably connected inside the opening groove. The upper end of the moving rod is fixedly connected with a connection fixing block through a connection column. The connection column penetrates through the connection disk and extends to the outside thereof, and is connected with a fixing groove through the connection fixing block in a clamping manner. The fixing groove is formed on the inner wall of the gear body.

[0004] To sum up, when it is necessary to make two gears with the same diameter rotate in the same direction but at different speeds, it is necessary to change the gear ratio of the internal transmission gears, and then it is necessary to frequently change the internal transmission gears. The operation is relatively cumbersome and will reduce the working efficiency of the multi-stage transmission gear.

[0005] Therefore, we propose a multi-stage transmission composite gear. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides a multi-stage transmission composite gear to solve the problems raised in the above background technique.

[0007] To achieve the above object, the present invention provides the following technical solution: A multi-stage transmission composite gear, including a support mechanism. The support mechanism includes a support frame. A first driven gear is arranged inside the support frame. A main gear is arranged on the inner wall of one end of the support frame away from the first driven gear. A second driven gear is rotatably connected to the inner wall of the support frame close to the main gear through a rotating shaft. A fixing frame is fixedly connected to the inner wall of the support frame. A first through hole is formed on the outer surface of the fixing frame close to the second driven gear. A third sliding groove is formed on the outer surface of the second driven gear close to the first through hole. The inner wall of the main gear is completely meshed and connected with the outer wall of the second driven gear. It also includes: Adjusting mechanism, including a rotating frame arranged inside the support frame. A second through hole is formed on the outer surface of the rotating frame. One side outer wall of the rotating frame close to the second driven gear is fixedly connected with a first connecting shaft. The first connecting shaft penetrates through the first through hole and is fixedly connected with a rotating wheel. The first connecting shaft is slidably connected to the inner wall of the first through hole. One end of the rotating wheel away from the first connecting shaft is rotatably connected to the inner wall of the third sliding groove. One side outer wall of the rotating frame away from the first connecting shaft is rotatably connected with a second connecting shaft. One end of the second connecting shaft away from the rotating frame is slidably connected with a limiting block. An auxiliary component is arranged outside the rotating frame. The rotating wheel makes the rotating directions and speeds of the rotating frame and the second driven gear the same through the first connecting shaft.

[0008] According to the above technical solution, the auxiliary component includes a sliding block movably sleeved on the outer surface of the second connecting shaft. One side outer wall of the sliding block close to the rotating frame is fixedly connected with a spring. One end of the spring away from the sliding block is fixedly connected with the rotating frame. The second connecting shaft is used to limit the sliding range of the sliding block. The limiting block adjusts the sliding position of the sliding block through threads.

[0009] According to the above technical solution, one outer wall of the sliding block is rotatably connected with an adjusting rod through a rotating shaft. One end of the adjusting rod away from the sliding block is rotatably connected with a tooth block through a rotating shaft. One inner wall of the tooth block is rotatably connected with a third sliding wheel through a rotating shaft. The third sliding wheel rolls along the inner wall of the second through hole. The tooth block is completely meshed and connected with the inner wall of the top of the first driven gear.

[0010] According to the above technical solution, one inner wall of the tooth block is rotatably connected with a first rotating rod through a rotating shaft. One end of the first rotating rod away from the tooth block is rotatably connected with a second rotating rod through a rotating shaft. One end of the second rotating rod away from the first rotating rod is rotatably connected with the rotating frame through a rotating shaft. The first rotating rod and the second rotating rod are used to improve the stability of the tooth block during the sliding process.

[0011] According to the above technical solution, a second groove is formed on the outer surface of the tooth block. One side inner wall of the support frame close to the second groove is rotatably connected with a second auxiliary wheel through a rotating shaft. The second auxiliary wheel rolls along the inner wall of the second groove. The second auxiliary wheel guides the movement of the tooth block through the second groove to maintain its meshing position with the first driven gear.

[0012] According to the above technical solution, a first groove is formed on the outer surface of the second driven gear away from the third sliding groove. One side outer wall of the support frame close to the first groove is rotatably connected with a second sliding wheel through a rotating shaft. One end of the second sliding wheel away from the support frame rolls along the inner wall of the first groove. The sliding of the second sliding wheel along the inner wall of the first groove is used to improve the stability of the second driven gear during the rotation process.

[0013] According to the above technical solution, a first sliding groove is provided on the outer surface of the first driven gear. One side outer wall of the support frame close to the first driven gear is rotatably connected with a first auxiliary wheel through a rotating shaft. The first auxiliary wheel rolls along the inner wall of the first sliding groove. The first auxiliary wheel rolls in the first sliding groove to prevent the radial displacement of the first driven gear.

[0014] According to the above technical solution, a second sliding groove is provided on the outer surface of the main gear. One side outer wall of the support frame close to the main gear is rotatably connected with a first sliding wheel through a rotating shaft. The first sliding wheel rolls along the inner wall of the second sliding groove. The main gear and the first driven gear have the same diameter and the same rotation direction.

[0015] Compared with the prior art, the present invention provides a multi-stage transmission compound gear, which has the following beneficial effects: 1. By setting a multi-stage transmission compound gear in the present invention, when it is necessary to keep two gears with the same diameter rotating in the same direction but at different speeds, the meshing ratio between the tooth blocks and the inside of the first driven gear can be adjusted by changing the distance between the tooth blocks through the adjusting mechanism, so that there is no need to replace the internal transmission gears, effectively improving the working efficiency of the multi-stage gear transmission.

[0016] 2. By setting a support mechanism in the present invention, the second sliding wheel slides along the inner wall of the first groove, enhancing the rotation stability of the second driven gear. At the same time, the first auxiliary wheel rolls in the first sliding groove to prevent the radial displacement of the first driven gear, thereby ensuring the stability of the first driven gear and the main gear during operation, and improving the working stability of the main gear and the second driven gear.

[0017] 3. By setting an adjusting mechanism in the present invention, the main gear drives the second driven gear to maintain the same rotation direction through meshing transmission. The rotating wheel is rotatably connected with the inner wall of the third sliding groove of the second driven gear, so that the second driven gear drives the rotating wheel to rotate synchronously. The rotating wheel ensures that the rotating frame and the second driven gear maintain the same rotation direction and speed through the first connecting shaft.

[0018] 4. By setting an auxiliary component in the present invention, when the rotating wheel rolls in the third sliding groove of the second driven gear, the rotating frame and the tooth blocks are driven to rotate synchronously through the first connecting shaft, and the second auxiliary wheel guides the movement of the tooth blocks along the second groove, ensuring that the tooth blocks continuously maintain a meshing state with the internal teeth of the first driven gear.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Embodiment 1: Refer to Figures 1 - 5 , the present invention provides a technical solution: a multi-stage transmission compound gear, including a support mechanism 5. The support mechanism 5 includes a support frame 501. Inside the support frame 501, there is a first driven gear 1. On the inner wall of one end of the support frame 501 away from the first driven gear 1, there is a main gear 3. On the inner wall of one side of the support frame 501 close to the main gear 3, there is a second driven gear 506 rotatably connected by a rotating shaft. On the inner wall of the support frame 501, there is a fixed frame 503 fixedly connected. On the outer surface of one side of the fixed frame 503 close to the second driven gear 506, there is a first through hole 504. On the outer surface of one side of the second driven gear 506 close to the first through hole 504, there is a third sliding groove 507. The inner wall of the main gear 3 and the outer wall of the second driven gear 506 are completely meshed and connected. It further includes: An adjustment mechanism 6, including a rotating frame 601 arranged inside the support frame 501. On the outer surface of the rotating frame 601, there is a second through hole 602. On the outer wall of one side of the rotating frame 601 close to the second driven gear 506, there is a first connecting shaft 603 fixedly connected. The first connecting shaft 603 passes through the first through hole 504 and is fixedly connected with a rotating wheel 604. The first connecting shaft 603 is slidably connected to the inner wall of the first through hole 504. One end of the rotating wheel 604 away from the first connecting shaft 603 is rotatably connected to the inner wall of the third sliding groove 507. On the outer wall of one side of the rotating frame 601 away from the first connecting shaft 603, there is a second connecting shaft 605 rotatably connected. One end of the second connecting shaft 605 away from the rotating frame 601 is slidably connected with a limiting block 606. On the outside of the rotating frame 601, there is an auxiliary component 607. When it is necessary to adjust the rotation speeds of two main gears 3 and the second driven gear 506 with the same diameter and the same rotation direction, an external power source drives the main gear 3 to rotate. The main gear 3 drives the second driven gear 506 to rotate in the same direction through meshing. The rotating wheel 604 is rotatably connected in the third sliding groove 507 of the second driven gear 506, so that the second driven gear 506 drives the rotating wheel 604 to rotate in the same direction. The rotating wheel 604 ensures that the rotating frame 601 and the second driven gear 506 maintain the same rotation direction and rotation speed through the first connecting shaft 603.

[0025] On the outer surface of the side of the second secondary gear 506 away from the third sliding groove 507, a first groove 508 is provided. On the outer wall of the side of the support frame 501 close to the first groove 508, a second sliding wheel 510 is rotatably connected through a rotating shaft. The end of the second sliding wheel 510 away from the support frame 501 rolls along the inner wall of the first groove 508. On the outer surface of the first secondary gear 1, a first sliding groove 2 is provided. The number of the first sliding grooves 2 is two, and the two first sliding grooves 2 are evenly provided on the outer surfaces of both sides of the first secondary gear 1. On the outer wall of the side of the support frame 501 close to the first secondary gear 1, a first auxiliary wheel 502 is rotatably connected through a rotating shaft. The first auxiliary wheel 502 rolls along the inner wall of the first sliding groove 2. On the outer surface of the main gear 3, a second sliding groove 4 is provided. The number of the second sliding grooves 4 is two, and the two second sliding grooves 4 are evenly provided on the outer surfaces of both sides of the main gear 3. On the outer wall of the side of the support frame 501 close to the main gear 3, a first sliding wheel 509 is rotatably connected through a rotating shaft. The first sliding wheel 509 rolls along the inner wall of the second sliding groove 4. The second sliding wheel 510 slides on the inner wall of the first groove 508, enhancing the rotational stability of the second secondary gear 506. At the same time, the first auxiliary wheel 502 rolls in the first sliding groove 2, preventing the radial displacement of the first secondary gear 1, ensuring the stability of the first secondary gear 1 and the main gear 3 during rotation, and avoiding radial deviation.

[0026] Embodiment 2: Please refer to Figures 6 - 9 , on the basis of Embodiment 1, the present invention provides a technical solution: The auxiliary component 607 includes a sliding block 6071 movably sleeved on the outer surface of the second connecting shaft 605. The sliding block 6071 is in threaded sliding connection with the outer surface of the second connecting shaft 605 where they are fixedly connected. On the outer wall of the side of the sliding block 6071 close to the rotating frame 601, a spring 6072 is fixedly connected. The end of the spring 6072 away from the sliding block 6071 is fixedly connected to the rotating frame 601. The second connecting shaft 605 is used to limit the sliding range of the sliding block 6071. The limiting block 606 adjusts the sliding position of the sliding block 6071 through threads. When it is necessary to adjust the position of the tooth block 6074 in the second through hole 602, the limiting block 606 drives the sliding block 6071 to slide along the outer surface of the shaft by rotating the second connecting shaft 605, thereby adjusting the distance between the tooth blocks 6074. Furthermore, the number of contacts between the tooth block 6074 and the teeth on the inner wall of the first secondary gear 1 can be changed, so as to adjust the transmission ratio between the tooth block 6074 and the first secondary gear 1.

[0027] The outer wall of the sliding block 6071 is rotatably connected to an adjusting rod 6073 through a rotating shaft. One end of the adjusting rod 6073 away from the sliding block 6071 is rotatably connected to a toothed block 6074 through a rotating shaft. The inner wall of the toothed block 6074 is rotatably connected to a third sliding wheel 6078 through a rotating shaft. The third sliding wheel 6078 rolls along the inner wall of the second through hole 602. The toothed block 6074 is completely meshed and connected with the inner wall of the top of the first driven gear 1. The inner wall of the toothed block 6074 is rotatably connected to a first rotating rod 6076 through a rotating shaft. One end of the first rotating rod 6076 away from the toothed block 6074 is rotatably connected to a second rotating rod 6077 through a rotating shaft. One end of the second rotating rod 6077 away from the first rotating rod 6076 is rotatably connected to the rotating frame 601 through a rotating shaft. When the adjusting rod 6073 pulls the sliding block 6071 to drive the toothed block 6074 to move, the third sliding wheel rolls on the inner wall of the second through hole 602 to assist the movement of the toothed block 6074. When the toothed block 6074 approaches the rotating frame 601, the first rotating rod 6076 and the second rotating rod 6077 act together to ensure the stable sliding process of the toothed block 6074.

[0028] A second groove 6075 is formed on the outer surface of the toothed block 6074. One side inner wall of the support frame 501 close to the second groove 6075 is rotatably connected to a second auxiliary wheel 505 through a rotating shaft. The second auxiliary wheel 505 rolls along the inner wall of the second groove 6075. When the rotating wheel 604 rolls on the inner wall of the third sliding groove 507 of the second driven gear 506, the rotating frame 601 and the toothed block 6074 are driven to rotate synchronously through the first connecting shaft 603. At the same time, the second auxiliary wheel 505 guides the movement of the toothed block 6074 along the second groove 6075 to ensure that the toothed block 6074 and the inside of the first driven gear 1 always remain in a meshed state.
