Product Q&A

Q:What is the rated power and torque capacity of this gearbox?

Our gearbox manufacturing capabilities cover a power range of 0.15 kW to 40,000 kW and gear ratios from 1 to 450.

Q:What is the noise level at rated load and speed?

The measured sound pressure level is 78 dB(A) at one meter distance under rated load and 1,500 rpm input, tested per ISO 3746 in a semi-anechoic chamber. Low-noise variants with ground gears and optimized housing stiffness can reduce this to below 72 dB(A).

Q:What materials are used for the gears, shafts, and housing?

The gears are made from 20CrMnTiH (AISI 5120H equivalent) carburizing-grade alloy steel. Output shafts use 42CrMo4 (AISI 4140) forged alloy steel. The housing is cast from GG25 (ASTM A48 Class 30) grey cast iron, with ductile iron GGG40 available for high-vibration applications.

Q:What gear heat treatment process is used, and what are the hardness values?

All helical gears undergo vacuum carburizing followed by oil quenching and tempering. The tooth surface hardness reaches 58-62 HRC, with a case depth of 0.8-3.0 mm. The core hardness is maintained at 32-45 HRC to ensure toughness and resistance to tooth fracture.

Q:What quality management system is certified?

Our manufacturing facilities are certified to ISO 9001:2015 for quality management, ISO 14001:2015 for environmental management, and ISO 45001:2018 for occupational health and safety.
