Description

Technical Field

[0001] The utility model relates to the field of gear boxes, in particular to a built-in planetary gear box. Background Art

[0002] Planetary gears refer to a gear system that, in addition to being able to rotate around its own axis like fixed-axis gears, also has its axis rotate around the axes of other gears along with the planetary carrier. The rotation around its own axis is called "rotation", and the rotation around the axes of other gears is called "revolution", which is used to make planetary gears.

[0003] A planetary gearbox is a planetary reduction box. A built-in planetary gearbox is a planetary gearbox in which the planetary gears are hidden inside the gearbox. A planetary gearbox is also called a gearbox. Its structure is a mechanism in which multiple planetary gears rotate around a sun gear. It is also a mechanism that reduces the transmission speed ratio and proportionally increases the motor torque.

[0004] However, when the existing planetary gearbox is used, it is not conducive to injecting lubricating oil between the planetary gears in the planetary gearbox. After the planetary gears are used for a long time, if the lubricating oil is not injected between the planetary gears in time, it is easy to cause wear between the planetary gears, which is not conducive to the use of the planetary gears.

[0005] Therefore, we propose an internal planetary gearbox. Utility Model Content
