Description

Technical Field

[0001] This utility model relates to the field of helical gear shaft technology, specifically to a stable clamping and adjusting cylindrical helical gear shaft. Background Technology

[0002] In the field of mechanical transmission, cylindrical helical gear shafts are widely used in various mechanical equipment, playing a key role in transmitting power and motion.

[0003] However, traditional cylindrical helical gear shafts have many shortcomings. In the existing technology, cylindrical helical gear shafts are mostly integral structures with a fixed number of gear teeth, making it difficult to flexibly adjust according to actual working conditions. If a different transmission ratio is required, the entire gear shaft assembly often needs to be replaced, which is costly and cumbersome.

[0004] Meanwhile, during the power transmission process, integral gear shafts usually require additional adapters to connect with external structures. This not only increases the power transmission path and leads to increased power loss, but also occupies more equipment space and reduces space utilization.

[0005] In addition, the fixed length of traditional gear shafts cannot adapt to the needs of different installation environments. On-site installation often requires adaptation modifications to other parts of the equipment, resulting in low installation efficiency and poor flexibility. Utility Model Content

[0006] Technical problems to be solved

[0007] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a stable clamping and adjusting cylindrical helical gear shaft, which can effectively solve the problems in the existing technology.

[0008] Technical solution

[0009] This utility model provides a stable clamping and adjusting cylindrical helical gear shaft, including a helical gear, with protruding teeth fixed inside the helical gear and an inner shaft fixed inside the helical gear. The inner shaft and the helical gear are connected by a connecting ring, and a connecting shaft is sleeved inside the inner shaft. An outer mating groove is concentrically formed on the outer wall of the helical gear. The inner shaft includes an inner ring and an outer protrusion fixed to the outer side of the inner ring. The outer protrusion has an inner mating groove formed inward. The connecting ring includes a retaining ring and two sets of protruding rings set on the inner side wall of the retaining ring.

[0010] Furthermore, multiple sets of the outer protrusions are equidistantly arranged, and the grooves and teeth between the outer protrusions are engaged and fixed.

[0011] Furthermore, threaded structures are provided on the outer sidewalls, outer mating grooves, and inner sidewalls of the two sets of convex rings, and the two sets of convex rings are engaged and fixed with the outer mating grooves and inner mating grooves.

[0012] Furthermore, the inner shaft has a notch inside, and the connecting shaft has a connecting tooth fixed on the outside, with the outer side of the connecting tooth engaging with the notch.

[0013] Furthermore, the buckle is a hollow ring structure.

[0014] Furthermore, two sets of helical gear structures are fitted on both sides of the inner shaft.

[0015] Beneficial effects

[0016] This invention features an inner shaft structure located in the middle of two sets of helical gears. Users can attach helical gears with different numbers of teeth to the outer side of the inner shaft as needed. The gears engage with the outer protrusions on the outer side of the inner ring, enabling coordinated transmission. Then, the protruding ring in the retaining ring meshes with the outer and inner mating grooves, thus combining the two helical gears and the inner shaft in the middle to form a unified whole. Finally, the connecting shaft is assembled by connecting the connecting teeth to the notch. Therefore, in use, this device simplifies power transmission by dividing the inner shaft in two and engaging it with helical gears of different numbers of teeth, eliminating the need for external power transfer. This reduces power loss and space occupation, improving space utilization. The two are connected and fixed by a connecting ring. Users can adjust the length of the inner shaft as needed for easy on-site installation and docking.

[0017] In this device, multiple sets of notched structures are opened in the inner shaft, which can be connected to the connecting teeth on the outside of the connecting shaft. The outside is fixed by threads. During use, the helical gears move in the same direction, effectively avoiding slippage and transmission failure. Attached Figure Description
