As the core transmission components, precision reducer gears feature narrow and complex tooth roots, tooth grooves and meshing gaps. A large amount of lapping compound, fine metal debris, cutting oil and polishing residue remain after grinding. Conventional manual wiping and ordinary spray cleaning can only clean the outer surface of gears, while contaminants hidden in dead zones of tooth gaps are hard to remove. Once tiny particles stay in meshing areas after assembly, they will aggravate tooth surface wear, increase operating noise, reduce transmission accuracy and directly shorten the service life of precision reducers. Developed specifically for precision reducer gears, Buck ultrasonic cleaning equipment relies on the ultrasonic cavitation effect to deeply remove debris and oil from dead corners of tooth gaps without damaging precision tooth surfaces. It stably controls assembly cleanliness and extends the service life of reducers.

Buck adopts a high-frequency ultrasonic system adapted to gear materials. The ultrasonic power and frequency can be flexibly adjusted according to gear module, material and precision class. During cleaning, micro-jets and shockwaves generated by the collapse of cavitation bubbles in liquid fully penetrate tiny gaps such as tooth root fillets, relief grooves and keyways that are inaccessible to conventional cleaning. The lapping compound, micron-sized metal debris and cured oil embedded inside tooth grooves are stripped layer by layer. After separation from workpieces, contaminants suspend in the cleaning medium, so there will be scratches or impact damage on hardened tooth surfaces and precision meshing profiles. The original geometric accuracy and surface roughness of gears are fully preserved.

The machine adopts an integrated multi-tank process design, integrating main ultrasonic washing, multi-stage rinsing, precision filtration, air cutting and hot air drying functions. Circulation filtration and magnetic chip removal devices are installed inside the cleaning tank to continuously capture stripped fine metal particles and prevent secondary adhesion of contaminants on gear surfaces, ensuring highly consistent cleaning results for batches of workpieces. Hot air drying after cleaning eliminates residual water in tooth grooves and micro gaps to avoid gear rusting. It meets the cleanliness inspection standards before assembly of precision reducers and is suitable for mass production of various high-end precision reducer gears such as harmonic, planetary and robot joint reducers.

The whole machine adopts a 316L stainless steel tank, equipped with a fully automatic PLC control system. Multiple sets of cleaning processes can be preset. Processes can be switched with one click when replacing gears of different specifications to reduce changeover time. It can be matched with automatic loading and unloading tooling and connected to automated production lines to realize continuous batch cleaning, greatly reduce manual intervention and improve production efficiency. The equipment is equipped with liquid level, temperature, ultrasonic overload protection and consumable early warning functions for stable, safe operation and convenient maintenance.

It is widely used for gear cleaning of humanoid robot joint reducers, new energy transmission reducers, planetary reducers for automation equipment and servo precision reducers, meeting the strict cleanliness control requirements of OEMs. Stable and controllable cleaning processes reduce assembly failures such as abnormal noise, stalling and premature wear of reducers, and improve transmission stability and product reliability of reducers. Buck supports sample cleaning tests for customers. Cleaning effects of gears can be verified on-site with customized exclusive cleaning processes, providing reliable cleaning solutions for the manufacturing of precision transmission parts.
