Typical application scenarios and cases of planetary reducers

1. Industrial robot field:
Application locations: J1-J6 joints of 6-axis robots, among which J2-J5 joints (with larger load) use precision helical gear planetary reducers (reversal gap ≤ 1 arc minute, rated torque 50-500 N·m), and J1/J6 joints use high rigidity type (reversal gap ≤ 0.5 arc minute); 
Case: An automotive welding robot, using 4 precision planetary reducers, operated for 5 years without failure, the repeat positioning accuracy remained at ±0.02mm, meeting the welding accuracy requirements (±0.05mm). 
2. CNC machine tool field:
Application locations: spindle drive (high-speed planetary reducers, input speed 3000-6000 r/min, transmission efficiency over 98%), feed axis (precision type, reversal gap ≤ 1 arc minute); 
Case: A vertical machining center, the spindle uses high-speed planetary reducers, the maximum speed is 6000 r/min, when processing aluminum alloy parts, the surface roughness reaches Ra0.8μm, meeting the precision processing requirements. 
3. New energy field:
Application locations: wind power equipment yaw drive (explosion-proof planetary reducers, rated torque 1000-5000 N·m, protection grade IP65), photovoltaic tracking system drive (small precision type, reversal gap ≤ 3 arc minutes); 
Case: A 2.5MW wind turbine at a wind farm, yaw drive uses 3 explosion-proof planetary reducers, operating for 8 years, only replaced 2 times the oil seals, with low failure rate, meeting the high reliability requirements of wind power equipment.
