Abstract

The embodiment of the invention relates to a ring-shaped sealing part and a robot. The ring-shaped sealing part (100) comprises a peripheral wall (100) and a ring-shaped part (200), wherein the peripheral wall (100) extends in the axial direction (A) of the ring-shaped sealing part (10); the ring-shaped part (200) extends towards the inner part of the peripheral wall (100) from one side of the peripheral wall (100) in a radial direction (R) of the ring-shaped sealing part; and while observed from the section cut in the radial direction (R), the ring-shaped part (200) and the peripheral wall (100) define an L shape. According to the embodiment disclosed by the invention, the ring-shaped sealing part is reasonable in structure, and improves sealing effect of the robot with lower cost.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the field of industrial robots, and more particularly relate to a robot using a labyrinth seal. Background technique [0002] Industrial robots have a wide range of applications and can be used, for example, to grip workpieces on production lines. The robot needs a lot of lubricating oil during operation to ensure its normal operation. Lubricating oil fills most of the space inside the robot and can cause leaks if not well controlled. A large amount of leakage not only leads to waste of lubricating oil, but also may bring safety hazards. Even if the amount of leakage is not large, it will pollute other components on the production line, which greatly affects the user experience. [0003] Therefore, the robot has a high demand for sealing reliability. How to improve the internal sealing of the robot under the premise of ensuring the normal operation of the robot, so as to prevent the leakage o...
