This gets rid of oil blade and can be thrown on rear axle shaft gear bearing and through shaft bearing by the lubricating oil under axle housing, thus can make rear semiaxis
Gear-bearing and through shaft bearing obtain sufficient lubrication.
2. bearing premature wear, ablation and through shaft can be avoided to rupture:
Owing to lubricating oil can be thrown on through shaft bearing by the present invention by getting rid of oil blade, through shaft bearing can be made fully to be moistened
Sliding, thus bearing premature wear, ablation can be avoided, through shaft also can be avoided to rupture.
3. can avoid beat the fault such as tooth, spring tooth:
Owing to lubricating oil can be thrown on rear axle shaft gear bearing by the present invention by getting rid of oil blade, rear axle shaft gear bearing can be made to obtain
To sufficient lubrication, thus can avoid beating a series of faults such as tooth, spring tooth.
4. reduce noise, reduce fault, the purpose that increases the service life:
Owing to the present invention can make rear axle shaft gear bearing and through shaft bearing obtain sufficient lubrication, reduction noise, minimizing are reached
Fault, the purpose increased the service life.
5. simple in construction, holistic cost is low:
The overall structure of the present invention is fairly simple, and holistic cost is low, it is easy to promote the use of.
Below, the technology of the integral type main gearbox assembly that band to the present invention gets rid of oil blade is special in conjunction with the accompanying drawings and embodiments
Levy and be further described.
