Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a waterproof and dustproof precision reducer. Background Art

[0002] As a commonly used transmission component in modern times, the main function of the reducer is that when the rotational force is transmitted to the inside of the reducer through the external transmission component, the reducer transmits the rotational force to the inside of the transmission component and adjusts the output speed of the reducer through the difference in gear module. However, the existing reducer lacks waterproof and drying components. When water vapor enters the interior of the reducer, the reducer cannot absorb the water vapor to prevent rust inside the reducer, thereby affecting the service life of the reducer.

[0003] Compared with the existing reducer, the utility model adds a waterproof drying component. When water vapor enters the interior of the reducer, the reducer can absorb the water vapor to prevent rust from occurring inside the reducer, thereby extending the service life of the reducer.
