To prevent and control the problem of oil leak÷✘σage of reducer, it should b>≠e improved and perfected from va♠♠rious aspects such as technology, prod§<uction process, and quality control, and ε the specific measures are ‍∞∑ as follows:

1. The groove of the welded box ↔ steel plate is designed according to the thic±€kness regulations, and the we∏λld is inspected by MT and UT according to the st€×¶βandard requirements; The casting box λ±×₩is inspected by MT and UT flaw detection,∞π so as to improve the casting process of←‍ the casting and improve the casting qφ±<→uality of the casting.

2. Optimize the scheme design, analyze and cal♦♦culate the statics and dyn≤​amics of materials and structures under diff₩'∑©erent loads for the stiffness and strength oλ←φf the box, and analyze the≤→β modality of the box components to complete the $‍'rationality of the design.

3. Add a hardened shaft sleeve on the input and∞↓← output shaft, grind the hardened surface, ±×₹™improve the surface roughn® ¶>ess, ensure the hardness and r‍>φ oughness of the contact with the oil sea€÷​l lip, and design to increaα •se the special lubrication of the oil sea♥≥★≠l to avoid the early wear ¥¶×★of the oil seal.

4. For the reducer with thin oil lubrication≤ε£ and mechanical seal, increaπ®>se the oil return hole on the b¶​​≥earing seat, set the throttle slee↔✘φ™ve according to the flow calculat→§ion requirements, and accurately distribute≤↕↕γ the flow rate of each lubrication point t∏♣δ‌o avoid lack of oil or excessivα₹≥e oil supply due to uneven oil distribution.∑γ ε

5. The thread at the oil drain $ε<γhole is changed to post-welding processin​¶g to ensure the fit and toleranπ‌₽ce requirements of the thread; Inc‍ ↕rease the contact area between th©←'•e end face of the screw plug and the≥≤> oil drain hole to ensure good cont♣‍βact with the end face of the gasket↔•♠δ.

6. Use a gasket between the o ★bservation hole cover plate₽  and the box body of the reducer ≥≠×to increase the thickness of the sight hole cov↕φ‍>er plate and reduce the roughness of the j®φ★Ωoint part; For covers that♥≤→" require the use of plexiglass, steel backi‌♣←ng plates are added to the plexiglass fastening₹÷ bolts to prevent breakage oγ✘f plexiglass.

7. Strict procurement requirements toσ↔‍σ ensure the quality of ball valves and seals, a'γ<•nd avoid the occurrence of oil l"±eakage in use due to the quality of ↕×π☆such parts.

8. Strictly control the assembly quality requireπ∑ments. Formulate reasonable assembly procedures∑≠£, strictly implement assembly process steps, imp£ ✔‌rove the assembly inspection pr¶φ≠∞ocess, formulate assembly and lubrication pipeli← €ne configurations, and mak≥"קe inspection records of the assembly pr✘∏÷ocess, so as to eliminate oil le‌≈akage caused by processing and  $↕assembly.

9. Control and inspect the processing a≈★nd manufacturing process of each×←&↔ key component involved in the∑∑✔ oil leakage of the reducer, and strictly implem≈σent the process control regulations.

10. Formulate a quality assessment sysβε≥§tem to improve the quality awareness of$​ ‍ managers and employees.

11. Strengthen the guidance on the in∑>§stallation and use of the red©"ucer on the user's site to avoid the occur‍★±γrence of leakage caused by installation, ¥γuse, overhaul and maintenance.
