Description

Technical Field

[0001] This utility model relates to the field of planetary carrier technology, specifically a planetary carrier. Background Technology

[0002] Planetary gears are gear systems that, in addition to rotating around their own axis of rotation like top gears, also have their axis of rotation rotate around the axes of other gears along with the planet carrier. They mainly consist of a planet carrier, planet gears, a sun gear, and an internal ring gear. During assembly, multiple planet gears are mounted on the planet carrier, with the outer sides of the planet gears meshing with the internal ring gear and the inner sides of the planet gears meshing with the sun gear.

[0003] Patent application CN222864084U discloses a model-level planetary carrier, specifically relating to a model-level planetary carrier including a mounting base. A hollow ring is fixedly connected to the upper surface of the mounting base, and four planetary gears are rotatably connected to the inner wall of the hollow ring. The four planetary gears are meshed with each other. The upper surface of the hollow ring is provided with mounting holes, and the outer surface of the hollow ring is provided with a lubrication device. The lubrication device includes a storage section, a conveying section, a flow section, and a filtering section. The storage section includes a small oil tank and an oil filling hole. By setting up a lubrication device, the problem of inconvenience or inability to maintain the internal planetary gears of the planetary carrier is solved. By injecting lubricating oil into the small oil tank outside the planetary carrier, and starting a water pump to carry the lubricating oil into the interior of the planetary carrier, the lubricating oil flows directly to the planetary gears through the oil outlet hole inside the planetary carrier, thus maintaining the planetary gears, preventing rust, and affecting their service life.

[0004] However, the planetary carriers disclosed above are inconvenient to disassemble and assemble, lack a quick locking structure, and have limited freedom of movement, unable to adaptively adjust the distance between mounting brackets to meet the needs of gears of different thicknesses. Utility Model Content

[0005] The purpose of this utility model is to provide a planetary carrier that solves the problems of existing planetary carriers being inconvenient to disassemble and assemble, lacking a quick locking structure, having limited freedom of movement, and being unable to adaptively adjust the distance between mounting brackets to meet the needs of gears of different thicknesses.
