Description

Technical Field

[0001] The utility model relates to the technical field of precision accessories, in particular to an assembly worm for a drone. Background Art

[0002] With the rapid development of drone technology, the power transmission systems within them are placing higher demands on precision and stability. Worm gears, as a common transmission element, are widely used in drone power transmission systems. Their high reduction ratios and smooth operation make them a key component, particularly in controlling rotation and positioning accuracy. However, in practical drone applications, worm gears not only need to achieve precise power transmission but also must work closely with other transmission elements, such as gears.

[0003] In traditional manufacturing processes, worms and gears are typically machined from a single piece. That is, the worm and gear are integrally formed and machined. While this approach ensures a certain level of structural strength and stability, it also has significant drawbacks. During this process, a significant amount of material waste is generated, especially for high-precision parts, where the waste ratio is even higher, significantly increasing manufacturing costs. Furthermore, this method limits the flexibility of the part within the manufacturing process. Any deviation in the machining process will result in the entire part being scrapped, further increasing costs.

[0004] In response to the above problems, we have introduced a worm gear for UAV assembly. Utility Model Content

[0005] The utility model discloses a worm gear for assembling a drone, aiming to solve the technical problems in the background technology.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A worm gear for assembling an unmanned aerial vehicle comprises a worm body, a bearing and a gear. The worm body consists of a welding end, a mounting end, a driving end and a worm thread. The worm thread is arranged on the driving end, the mounting ends are symmetrically arranged at both ends of the driving end, the welding end is symmetrically arranged at one end away from the two mounting ends, and the welding end, the mounting end and the driving end are arranged to have the same center.

[0008] The worm body is driven by the worm thread, driving the driving end, the mounting end and the welding end to rotate.

[0009] In a preferred solution, a mounting hole is provided on the bearing, and the bearing is used in conjunction with the mounting end through the mounting hole.

[0010] The bearing is installed on one of the mounting ends and tightly connected.

[0011] In a preferred solution, a welding hole is provided on the gear, and a protruding end is provided on one side of the gear, and the protruding end contacts the inner ring of the bearing.

[0012] The gear is mounted on one of the welding ends and contacts the inner ring of the bearing through the raised end to limit the bearing.

[0013] In a preferred solution, the gear is used in conjunction with the welding end through a welding hole, and a welding groove is provided on the gear.

[0014] The welding groove is used to weld the gear to the welding end.

[0015] In a preferred solution, an arc-shaped chamfer is provided on the welding end.

[0016] Arc chamfers can increase the welding area and improve welding quality.

[0017] In a preferred solution, the worm body and the gear are both made of metal or plastic.
