When cleaning the inside of the GR137 - Y5.5 - 6P - 113.91 - M4 reducer, the following precautions are given:
Safety first
Be sure to cut off the power supply of the reducer before cleaning, and make sure that the power supply will not be turned on accidentally during cleaning. You can hang the warning sign 'Inspecting, please do not close the switch' at the power switch. If necessary, arrange a dedicated person to monitor it.
Wait until the reducer stops completely and cools before cleaning to prevent scalds and accidental start of equipment and causing personal injury
Keep records and mark
Before disassembling the reducer shell and internal parts, carefully observe and record the installation position and connection methods of each component. If necessary, take a photo or draw a simple diagram for subsequent correct installation.
For some important parts, such as gear shaft bearings, you can use marking pens or labels to avoid errors during installation
Correct disassembly
According to the removal procedures of the reducer, use appropriate tools to gradually remove components such as the shell end cover gear shaft during the disassembly process. Pay attention to avoid damage to the surface and threads of the parts. If the bolts are difficult to disassemble, do not forcefully twist them. You can use rust remover or heating to deal with them.
Properly keep the removed parts to prevent loss or damage. Small parts can be placed in a special part box and marked
Choose the right cleaning supplies
Use clean brush rags and special cleaners to clean the internal cleaners. Cleaners should be selected. Products that are non-corrosive to metals and can effectively remove oil and impurities. Avoid using too sharp or hard tools to avoid scratching the surface of parts.
For stubborn oil stains and impurities, you can use an appropriate amount of gasoline or kerosene to wipe it, but you should pay attention to fire and explosion protection. After use, you should use a clean rag to dry the residual oil in time, and ensure good ventilation so that the volatile oil and gas can be discharged as soon as possible after use.
Clean key parts
Focus on cleaning key parts such as the gear bearing journal, remove oil, iron filings, dust and other impurities on the surface. Check whether the gear teeth surface has defects such as wear, cracks, pitting, etc. If any discovery is found, record and evaluate it in time.
When cleaning the bearing, pay special attention to maintaining its cleanliness to avoid impurities entering the bearing and check whether the clearance of the bearing is normal and whether the rotation is flexible.
For the inside of the reducer box, clean the oil and debris, check whether there is any corrosion and deformation of the inner wall of the box, etc.
Prevent secondary pollution
During the cleaning process, pay attention to keeping the working environment clean and avoid surrounding dust and debris entering the reducer. Clean plastic cloth or canvas can be laid around the cleaning area to prevent dust from rising on the ground
Cleaned parts should be placed on a clean workbench or packaged in clean plastic bags to prevent recontamination.
Install and reset
After cleaning, according to the recorded and marked positions, the parts should be installed back to their original position. During the installation process, ensure that all parts are installed in place. Connect and tighten the bolts with a torque wrench according to the specified torque to avoid equipment failure due to loose bolts.
When installing seals, be careful to check whether they are intact and whether the installation position is correct to ensure that the seal is good and prevent oil leakage.
