R series cylinder gear reducer has hard teeth face cylinder helical geartransmission; it can realize the same axis (double - stage and three ) andparallel axis transmission. Its characteristic is:Features:a) Compact construction, saves space for mounting, large load - bearing capacityand long lifeb) Little difference between transmission ratio ratec) High transmission efficiency and low noised) Block design, several rates can be combinated togethere) Specification: 17 - 167 thirteen type totallyf) Input power: 0.12 - 160kW (Four - stage )g) Output torque: 50 - 18,000Nmh) Transmission ratio: 1.3 - 280i) By two mounting form: feet form and flange form.
