What precautions should be taken for cleaning the QJRS-D710 soft tooth surface reducer
The core of cleaning treatment for QJRS-D710 soft tooth surface reducer is to prevent dust from entering the lubrication system and to prevent cleaning agents from corroding the seals. Especially in high temperature and high humidity environments, it is necessary to prioritize cleaning the ventilation plug and heat dissipation structure to prevent water vapor from mixing with dust to form abrasives that accelerate gear wear.1、 Safety and preparation before cleaning
Before starting to clean, it is essential to take the following protective measures to ensure personal safety and equipment integrity:
Shutdown cooling: The power must be cut off and locked with a tag, waiting for the gearbox to cool down to room temperature (or at least below 40 ℃) to prevent high temperature burns or rapid evaporation of cleaning agents.
Protective equipment: Operators should wear dust masks, goggles, and oil resistant gloves to avoid inhaling dust or cleaning agents coming into contact with the skin.

Tool preparation: Prepare a soft bristled brush (made of nylon material), dust-free cloth, neutral cleaning agent, high-pressure air gun (with controllable pressure), and a dedicated oil pan.
2、 External cleaning: dust removal and decontamination
The focus of external cleaning is to remove surface dust and oil stains, while protecting the paint surface and markings:
Dry dust removal: First, use a soft bristled brush to gently sweep away the floating dust on the shell, heat sink groove, and bolt head, avoiding direct blowing that may cause dust to fly into the respirator.
Wet wiping: For stubborn oil stains, a dust-free cloth dipped in a small amount of kerosene or specialized cleaning agent can be used to wipe the shell, flange surface, and shaft end. It is strictly prohibited to directly spray high-pressure water guns to prevent moisture from seeping into the interior of the box.
Key parts cleaning: Focus on inspecting and cleaning the ventilation plug (respirator). If blockage is found, immediately clear or replace the filter element. This is the key to preventing internal negative pressure from inhaling dust.
3、 Internal cleaning: lubrication system protection (core link)
If the lubricating oil has been contaminated with dust (blackening, containing particles), internal flushing must be carried out, which is a decisive step in extending the service life of the equipment:
Drain old oil: Open the oil drain plug and drain the deteriorated lubricating oil into a dedicated container. It is strictly prohibited to dump it at will, which may cause environmental pollution.
Circulating flushing: Inject about 1/3 of the capacity of diesel or specialized gearbox cleaning agent into the box, start the gearbox and run it without load for 5-10 minutes, use gear agitation to dissolve the oil sludge and dust in the cleaning agent, and then drain it. If the discharged liquid is still turbid, rinse again 1-2 times.
Component inspection: If disassembly is possible, use a soft brush to clean the attachments on the gear tooth surface and bearing raceway; Apply anti rust grease to the corroded areas.
Add new oil: After cleaning, add suitable anti-wear and anti-corrosion gear oil to the center line of the oil window, and manually rotate several times to ensure even lubrication.
