1434691 Mounting parts on shafts; cams BORG-WARNER CORP 17 Jan 1974 [9 Feb 1973] 02307/74 Headings F2U and F2K A cylindrical member 16, such as a bearing race, pulley or gear part, is locked on to a shaft 10 by one or two tapered sleeves 36 which wedge between conical surfaces 20 and the shaft, an outwardly turned edge 44 on each sleeve being received in a groove 22. Each sleeve may be split or slotted as shown and provided with an outwardly-turned edge in the form of a flange or ears 44 for retention during transport. Upon assembly the sleeves are moved axially. In another embodiment, Fig. 11, the sleeve 56 is rotated during assembly to cause ears 54 to ride in a serpentine camming groove 52 and exert axial pressure. In Fig. 15 (not shown) the sleeve is constructed from sheet metal or tubing. In a further embodiment, Figs. 16 and 17 (not shown), the ears 84 are helically and spirally formed to cause axial and wedging movement when rotated during assembly. |
