Abstract

Abstract 1,010,137. Bearings. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE, and HYDROMECANIQUE ET FROTTEMENT S.A.R.L. Sept. 4, 1963 [Oct. 2, 1962; Jan. 17, 1963], No. 35004/63. Heading F2A. To facilitate self-alignment between two members one of which carries a bearing, at least one cushion device is interposed between said members. The device comprises a closure ring, grease and seals. In an embodiment, a shaft 6, Fig. 3, is carried by a halfbush 9 in a bearing body 7 having a cap 8 thereon. The body 7 is supported from a base 10 by cushion devices 11, each having grease in cavities 12 of the body 7, closure rings 13 and seal 14, 15, an enlarged view of the rings and seals being shown in Fig. 5; sufficient clearance being allowed between the rings 13 and the cavities 12 so as to allow the cushion device to swivel. The distance between the body 7 and the base 10 can be varied by means of adjusting-screws 18, one of which is provided for each cushion device so that grease may be supplied thereto from reservoirs 16. The cavities 12 may be of circular shape. In a further embodiment, belt and abutment rollers of a rotary furnace are mounted on cushion devices 11.
