The prevention and control of reducer oil leakage should be improved and perfected from the aspects of technology, production process and quality control.The specific measures are as follows: 1. The groove of welded box-type steel plate is designed according to the thickness regulations, and the weld seam is inspected by MT and UT according to the standard requirements; the casting box is inspected by MT and UT to improve casting technology and improve casting quality. 2. Optimize the design of the scheme, conduct static and dynamic analysis and calculation of the material and structure of the box stiffness and strength under different loads, and complete the modal analysis of the box components to achieve a rational design. 3. Increase the surface hardened sleeve on the input and output shafts, grind the hardened surface, improve the surface roughness, ensure the hardness and roughness of the lip contact with the oil seal, design special lubrication to increase the oil seal, and avoid the oil seal Premature wear. 4. For the reducer with thin oil lubrication and mechanical seal, increase the oil return hole on the bearing seat, set the throttle valve sleeve according to the flow calculation requirements, accurately distribute the flow of each lubrication point, and avoid the uneven distribution of oil. Lack of oil or excessive oil supply. 5. Change the thread of the oil drain hole to post-welding processing to ensure thread matching and tolerance requirements; increase the contact area between the screw plug and the end face of the oil drain hole to ensure good contact between the end faces of the gasket. 6. A sealing gasket is used between the observation hole cover and the reducer box, which increases the thickness of the observation hole cover and reduces the roughness of the joint.For the cover plate that needs to be used in conjunction with plexiglass, a steel backing plate is added to the plexiglass fixing bolts to prevent the plexiglass from being damaged. 7. Strict procurement requirements to ensure the quality of ball valves and seals, and avoid oil leakage due to the quality of parts in use. 8. Strict assembly quality requirements.Establish a reasonable assembly process, strictly implement the assembly process steps, improve assembly inspection procedures, formulate assembly and lubrication pipeline configuration 'assembly process inspection records', to prevent oil leakage caused by processing and assembly. 9. Formulate the 'Parts Process Control Processing Inspection Records' for the manufacture of key parts for oil leakage of reducers, and strictly implement the 'Processing Control Regulations'. 10. Establish a quality evaluation system to improve the quality awareness of managers and employees. 11. Strengthen the installation and use guidance of the user's on-site reducer to avoid leakage caused by installation, use, maintenance and other links.
