Description

Technical Field

[0001] The utility model relates to the technical field of lubrication mechanisms, in particular to a lubrication mechanism for a parallel planetary reducer. Background Art

[0002] A parallel planetary reducer is a mechanical device that combines the principles of a parallel kinematic mechanism and planetary gear transmission. It uses multiple planetary gears to simultaneously transmit power, utilizing a parallel structure to improve the system's load capacity, rigidity, and power output accuracy.

[0003] For example, the patent publication number CN219866188 U describes a lubrication structure for a planetary reducer, which describes a solution that uses a worm-driven threaded structure to achieve active material discharge, combined with gravity-assisted material discharge. By controlling the material discharge mechanism, the adhesive lubricating oil can be pushed into the cavity of the planetary reducer to prevent the lubricating oil from adhering to the discharge nozzle, causing material discharge difficulties, or dust from contaminating the lubricating oil, which would hinder the operation of the planetary reducer.

[0004] The above technology only considers the injection function of lubricating oil, but does not consider the discharge of lubricating oil. After the lubricating oil is injected, it can only passively remain inside the reducer housing. The debris generated by the operation of mechanical parts is mixed in the lubricating oil and cannot be discharged. These debris will increase the wear of the parts and reduce the service life of the reducer. To address the above problems, we provide a parallel planetary reducer lubrication mechanism.

[0022] 1. The utility model introduces the lubricating oil inside the casing into the filter box for filtration through the circulation component provided. The clean lubricating oil after filtration enters the liquid inlet pipe again through the oil guide pipe. Since impurities in the oil are removed, the mechanical wear of the reducer can be reduced, and the service life of the reducer is effectively improved.

[0023] 2. The utility model places the fixed plate inside the filter box, so that the filter plate and the magnetic rod filter the lubricating oil, and the magnetic rod can absorb the iron filings inside the lubricating oil.
