Grundfos Hydronic Valve Enclosure Assembly · 模型 256103
The solution to the task mentioned has been achieved using a set of 3 planetary gears with a fixed 50 teeth Inner ring, 18 teeth planet and 14 teeth sun gears, providing a step down ratio of 4.57. The sun of one stage of the planetary is connected to carriage connected to planets of the second stage. Further reduction is achieved using spur gears of 63, 18 and 10 teeth. Total Ratio achieved = 3*4.57*63/18*18/10 = 601.3 Input motor speed assumed is 600 RPM. Assuming efficiency of each stage to be 96% and the motor efficiency of 98%, the output torque will be 20.5 Nm at 1 RPM. Design Excellence: 1) All the parts like gears, carriages and the gearbox cover can be manufactured from MD FILLED NYLON 6. 2) All gears are Spur gears with 1mm module for each. 3) Assembly of the entire system in Z-direction. 4) All gears are mounted on bearings and bushings providing alignment and to prevent frictional losses and ensure long service life. 5) MD FILLED NYLON 6 gears ensure lubricant free operational status with moisture absorption and dimensional changes less than 0.05%. 6) All shafts are fixed to respective parts using set screws and retaining rings. 7) The gearbox can be replaced with a new one in case of failure with ease (if failure occurs). 8) Parts overhauling or replacement is easy and hassle free. 8) The system is compact, present inside the design envelope with space remaining for electronic boards, other accessories to be incorporated within.
