INTERNAL SPUN HUB AND METHOD OF MAKING SAME |
摘要 |
<p>A hub having a bore, in accordance with the present invention, is spun-roll formed of a portion of an annular sheet metal disc (10). The hub is formed by radially displacing a portion of the annular sheet disc (10) outward from the bore. The so formed hub that is integral to the annular sheet metal disc (10) forms a web having a thickness equivalent to or not less than a thickness of the annular sheet metal disc (10) before formation of the hub. The web may be used to spun-roll form a rim having a belt receiving portion and as such a one-piece spun roll formed pulley. The web may also be used to interconnect to a rim having a belt receiving portion as a separate piece from the hub and web.</p> |
