We are a leading gear motor manufacturer
Zhejiang Donghai Reducer is a leading manufacturer of gear motors and gearboxes.
Since 1991, we have specialized in manufacturing a wide range of gear motors and gearboxes including:
- helical gear motor (D series)
- helical bevel gear motor (T series)
- parallel shaft helical gear motor (P series)
- helical worm gear motor (E series)
- hoist drive (DQ series)
- heavy-duty helical gearbox (QYJH series)
- heavy-duty helical bevel gearbox (QYJB series)
- gear motor for the car parking system (DHTC series)
- spiral bevel gearbox (HD series)
HD series spiral bevel gear unit, the following is a trait
- the box is hexahedron, which can fit different direction mounting
- long-lift using and big load, smooth transmission, low noise, and transmission efficiency can up to 94-98%.
- Spiral bevel gears are made of low carbon alloy steel, and through quenching and whetting, come to high precision rigidity tooth transmission.
- HD series has seven specs, a big choosing range, and multi-output shaft mode which meets various situation
- Enhancing and reducing speed.
Application area
