Reducer  Concrete mixer truck planetary gearbox

1. The gear adopts grinding technology, with high precision, smooth operation, and high reliability; The sun gear is made of military grade materials

2. The key geometric tolerances of structural components such as planetary carriers are guaranteed to be below level 4-5;

3. Finite element analysis of the shell, using ductile iron with strong impact resistance;

4. The weight of the whole machine is 167KG, making it the lightest product in its class;

5. The installation length of the whole machine is small;

6. The flange adopts forging technology, with a swing angle of up to ± 5. The oil seal joint is treated with special technology, greatly improving the smoothness; Ensure sealing;

7. Customized materials and processes for bearings from manufacturers;

8. The input shaft is designed with impact resistant materials;

9. Static torsional strength, fatigue life, temperature rise, dynamic sealing and other tests are all higher than the national standard;

10. The back cover has undergone CAE strength analysis based on the weight of the motor (90KG) and the center of mass position, with a stress of less than 3MPa. It can be directly connected to the power motor without the need for a separate motor bracket.
