Key structures and materials

Structure of reducer

Gear system:

Material: Certified steel, with a tooth surface hardness of 58-62 Rockwell C after heat treatment, possessing infinite fatigue strength

Process: The gear tooth surface is ground or shaved to ensure low noise, low heat generation, and high mechanical efficiency

Bearings and shafts:

Bearing: Anti friction bearing, optimized load capacity and service life

Shaft design: Input/output shaft with fixed keys, output shaft with central threaded hole for easy installation of shaft components

Shell and seal:

Shell material: R37-R167 is SAE Grade 30 cast iron (or GG20 equivalent material); R27 is high-strength die cast aluminum

Sealing design: patented two-piece seal (double helix FKM inner seal+double lip NBR outer seal), providing 3 sealing surfaces to effectively resist pollutants

Leak proof design: The flange is equipped with an O-ring to prevent oil leakage when the installation surface is uneven

Structural features: high section modulus design, integral rigid structure, ensuring operational stability
