581,541. Resilient mountings. THIRY, L. F. Sept. 8, 1944, No. 17180. Convention date, Aug. 12, 1943. [Class 108 (iii)] In a resilient mounting consisting of inner and outer members connected together by a resilient member placed under axial compression by thrust members at the outer ends of the bearing, the resilient member is formed of a pair of cylindrical bushings each having at one end a number of circumferentially spaced radial projections. In Fig. 1, the resilient member which is mounted between the inner and outer members 10, 11 is made up of two bushings 15, Fig. 4, provided with radial projections 17 to locate the bushings in the outer member 11. The use of radial projections instead of flanges reduces the pressure required to distort the ends of the resilient member when it is placed under axial compression with a consequent increase in the pressure forcing the bushings together at the centre of the mounting. To prevent binding of the bushings on the outer member 11, the whole or part 18, Fig. 4 of the outer surface may be treated so that the coefficient of friction between the metal and rubber is reduced. A number of ways of doing this are described, and among others, the use of a thin film of methocrylate resin or the use of a varnish or drying oil such as tongue oil, perilla oil are mentioned. |
