Description

Technical Field

[0003] As a transmission component, in order to reduce the friction between the screw rod and the transmission nut to a greater extent and increase its service life, lubricating grease needs to be applied to its surface. However, during the long-term use of the screw rod, waste grease will accumulate between the threads, and it is necessary to clean it regularly and then reapply the lubricating grease.

[0004] For the screw rods of small-scale mechanical equipment with a screw rod diameter less than 60 mm and a length less than 3000 mm, they can be directly cleaned manually or disassembled and then cleaned with special machinery. However, for large-scale mechanical equipment with a screw rod diameter of more than 60 mm and a length of more than 3000 mm, the disassembly and cleaning are difficult. At present, the large-scale mechanical equipment adopts the method of manual cleaning, that is, scraping the grease in the screw rod groove with a scraper and then repeatedly wiping it with a rag coated with a cleaning agent. This cleaning method for the screw rods of large-scale mechanical equipment is time-consuming and laborious, easily damages the screw rod, and generates a large amount of waste such as oil cloths.
