AI Technical Summary
Existing new energy harvester drive axles are susceptible to mud and moisture ingress in humid and dusty environments, leading to wear of transmission components and lubricant leakage, which affects equipment lifespan and transmission efficiency.
The gear transmission box is covered by symmetrically distributed sealing protective covers A and B. The symmetrical structure achieves full-coverage protection. The sealing design of the protective covers prevents impurities from entering and ensures the sealing effect. They are fixed to the positioning seat with bolts to form an all-round seal.
It effectively prevents impurities such as mud, sand, and moisture from entering the gear transmission box, avoids wear and deterioration of lubricating oil, improves equipment transmission efficiency and service life, ensures long-term reliability and stability of the sealing effect, and facilitates inspection and maintenance.
