POLYGON ROTOR ATTACHMENT DEVICE |
摘要 |
<p>A rotor and shaft assembly for turbomachinery has a polygon shaped drive collar interposed between corresponding polygonal mating surfaces of a drive shaft and a rotor hub. The mating surfaces of the polygon collar, the drive shaft and the rotor hub may be sized both axially and radially for required torque transmission without the need for hub inserts or oversized shafts. The polygon drive collar is manufacturable using standard machine tools such as lathes and end mills that remove metal in a tool path following not more than two axes of simultaneous movement. A shaft end assembly secures the rotor and drive collar to the shaft.</p> |
