Description

Technical Field

[0001] The present invention relates to the technical field of gear transmission, in particular to a multi-stage transmission compound gear. Background Art

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

[0003] The patent application with application number CN202320781176.X discloses a compound gear, including a gear body and a connecting plate detachably connected to the gear body. At least four open grooves are opened on one side of the connecting plate. The interior of the open groove is vertically slidably connected to a moving rod. The upper end of the moving rod is fixedly connected to a connecting and fixing block through a connecting column. The connecting column extends through the connecting plate to its outside and is connected to a fixed groove through the connecting and fixing block. The fixed groove is opened on the inner wall of the gear body.

[0004] In summary, when two gears of the same diameter need to rotate in the same direction but at different speeds, the gear ratio of the internal transmission gear must be changed, which requires frequent replacement of the internal transmission gears. This operation is cumbersome and reduces the working efficiency of the multi-stage transmission gears.

[0005] To this end, we proposed a multi-stage transmission compound gear. Summary of the Invention

[0037] Example 2: Please refer to Figure 6-Figure 9 , based on the first embodiment, 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, and the sliding block 6071 is fixedly connected to the outer surface of the second connecting shaft 605 with a threaded sliding connection, and the outer wall of the sliding block 6071 close to the rotating frame 601 is fixedly connected to a spring 6072, and the end of the spring 6072 away from the sliding block 6071 is fixedly connected to the rotating frame 601, and the second connecting shaft 605 is used to limit the sliding range of the sliding block 6071, and the limit block 606 adjusts the sliding position of the sliding block 6071 through a thread. When the position of the tooth block 6074 in the second through hole 602 needs to be adjusted, the limit 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 spacing of the tooth block 6074, and then changing the number of contacts between the tooth block 6074 and the inner wall teeth of the first slave gear 1, thereby adjusting the transmission ratio between the tooth block 6074 and the first slave gear 1.

The inner wall of the support frame 501 on the side close to the second groove 6075 is rotatably connected to the second auxiliary wheel 505 via 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 slave gear 506, the rotating frame 601 and the tooth block 6074 are driven to rotate synchronously through the first connecting shaft 603. At the same time, the second auxiliary wheel 505 guides the tooth block 6074 to move along the second groove 6075, ensuring that the tooth block 6074 is always in meshing state with the inside of the first slave gear 1.
