If they are not filtered out, the aging and damage of the worm gear will be accelerated, which will lead to frequent maintenance or low efficiency. For this reason, we provide a high-precision worm gear reducer to solve the above problems. Utility Model Content

[0032] Working principle: When in use, first connect the oil pump 305 electrically through the wire, then use the power provided by the oil pump 305 to extract the lubricating oil inside the reducer for circulation filtration, then use the oil pipe 306 to guide the lubricating oil extracted by the oil pump 305 to the inside of the filter box 301, and then use the large sponge 302 and the small sponge 303 to filter out the excess impurities in the lubricating oil, and enter the inside of the reducer from the bottom of the filter box 301, thereby forming a cycle, which can be intermittently and repeatedly circulated and filtered. At this time, if it is necessary to replace the two sponges, The filter element can be quickly replaced by removing the side cover 304, taking out the sponge and then filling it with a new sponge. The oil tank 307 can be used to reserve a certain amount of lubricating oil for the reducer, and the connecting pipe 310 can be used to automatically refuel the reducer.
