1,038,110. Bearings; seals. J. KLEIN, E. BACH, and E. BACH, [trading as KUPFERASBEST-CO., GUSTAV BACH]. Oct. 22, 1964 [Oct. 23, 1963], No. 43086/64. Headings F2A and F2B. A combined bearing and seal of resilient material has a series of axial or helical ribs which support a shaft and at least one integral lip which seals said shaft. In an embodiment the ribs 2a, Figs. 1 and 2 (not shown), are parallel to the axis, portions 1 and 6 serve as seals and a portion extends around a housing 4. A cylindrical section 3 and a reservoir 13 are provided, the latter and grooves 5 between the ribs 2a being supplied with lubricant. The diameter of the shaft is greater than the internal diameter of the ribs 2a to prevent play therebetween, and the cylindrical section 3 limits radial displacement of the shaft. In other embodiments, the cylindrical section 3 is omitted; the ribs are helical-shaped; and a bearing-section 12, Fig. 5 (not shown), is separated from a sealing-section 6 by an oilchamber 14. |
