Overview:
DSW series high-torque gearbox is a hard-toothed gear transmission designed for single-screw extruders with reference to the design concepts and methods of German counterparts. The series of products are novel and beautiful in appearance, compact in structure, low in noise index, strong in carrying capacity and high in transmission efficiency. They can meet long-term trouble-free operation, leakage rate less than 1‰, main component life is more than 50,000 hours, and its bearing capacity. It is equivalent to the German E3HA series and is about 60% higher than the ZSYJ gearbox of the same specification.
Cabinet:
The design of the cabinet structure takes into account the function of absorbing noise. The material is made of high-quality cast iron, and it is fully aged and applied with advanced processing technology to ensure the high precision and maintainability of the cabinet.
Gear:
Gears and shaft materials are made of high-quality alloy steel 20CrMnTi, 20CrMnMo, 20CrNi2MoA. After carburizing and quenching, the hardness of the tooth surface reaches HRC58-62. After precision grinding, the grinding precision can reach 5 or above (GB/T10095-2001). At the same time, the profile and the spiral are modified to ensure the perfect meshing of the gear under load, thereby achieving low noise and high efficiency.
Bearing:
Bearings are generally selected from well-known Asian brands, such as ZWZ, DYZV, HRB, etc.
Oil seal:
Oil seals are generally selected from imported brands, such as SIMRIT in Germany and SOG in Taiwan.
