- H, B high-power gear reducer adopts universal design scheme, which can be transformed into industry-specific gearbox according to customer requirements.
- Realize parallel shaft, orthogonal shaft, vertical and horizontal general-purpose cabinets, with fewer types of parts and more specifications.
- Adopting the structure of the suction box body, large cabinet surface area and large fan, improved the temperature rise, noise reduction and reliability of the whole machine.
- Input mode: motor coupling flange, shaft input.
- Output mode: solid shaft with flat key, hollow shaft with flat key, hollow shaft with expansion joint, hollow shaft with spline joint, solid shaft with spline joint and solid shaft with flange joint.
- Installation method: horizontal, vertical, swing base type, torsion arm type.
- Speed ratio range 1.25-450, Torque range 2.6-900kN, Power range 4-5000kW
