HB series; M, MC series helical bevel gear speed reducer:

1. After special heat treatment of gears, it has high torque, high efficiency and long life.

2. Realize parallel axis, orthogonal axis, vertical and horizontal universal cabinets, with fewer parts and more specifications.

3. Adopt the suction box structure, the cabinet area is large, the cylindrical gear, spiral bevel gear adopts advanced grinding technology, which improves the temperature rise, reduces the noise, and improves the reliability of the whole machine. The power increases.

4. Input mode: motor coupling flange, shaft input.

5. 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.

6. Installation method: horizontal, vertical, swing base, torsion arm.

7. H, B series products have 3 to 26 specifications, the reduction transmission stage is 1 to 4, and the speed ratio is 1.25 to 450;


helical gear reducer

Technical Parameters:

1.Speed ratio range: 1.25-450

2.Torque range: 2.6-900kN

3.Power range: 4-5000kW


Main features:

1. The gear is ground by a high-precision gear grinding machine, with stable transmission, low noise, and 98% inter-stage efficiency;

2. Integral casting for base 12 and below, and split casting for base 13 and above. The shell is compact in size, high carrying capacity, stable transmission and low noise.

3. Good anti-leakage performance and good airtightness, which can be widely used in industrial production. Energy efficient.

4. After precision machining, ensure shaft parallelism and positioning bearing requirements.

5. Select high-quality forged steel materials, rigid cast iron box, and the gear surface is carburized, quenched and heat treated.
