XNUMX. Specification, model, transmission type, transmission ratio and output torque.
XNUMX. Main features
1重量轻、体积小、在相目条件下比硬齿面渐开线圆柱齿轮减速器重量减轻1/2以上，体职缩小1/2-1/3
2 High transmission efficiency: single-stage planetary speed reducer n=0.98
Two slow planetary reducer n=0.96
Three-stage planetary reducer n=0.94
3 The transmission power range is large, from less than 1 kilowatt to tens of thousands of kilowatts, and the greater the power, the more prominent the advantages and the higher the economic benefits.
Various assembly types, multi-sided installation, wide applicability, balanced operation and low noise under given manufacturing conditions.
5Using high-quality low-carbon Taiwan gold steel for carburizing and quenching, the external gear is grade 6 fine
Enter the level of similar products in industrialized countries.
