Abstract
1,248,048. Resilient bearing mountings. LICENTIA PATENT - VERWALTUNGS G.m.b.H. 8 Oct., 1968 [11 Oct., 1967], No. 47600/68. Headings F2A and F2S. [Also in Division H2] An electric motor is installed in an appliance (not shown) by means of a vibration-inhibiting element, Fig. 1, which consists of a centrally apertured body in which the portion 2 surrounding the aperture effects greater dissipation of vibrational energy, e.g. as heat, than other portions 3, 4. The portion 2 may be integral with a frame-like strip 19 surrounding the parts 3 and 4. The parts 2 and 19 may be of hard elastomeric material and the parts 3 and 4 of softer elastomer. The element of Fig. 1 is fitted over the outer race 2 of the motor shaft's ball bearing, Fig. 3, and projections 17, 18 from the bearing housing are fitted in apertures 5, 6 in the parts 3, 4 of the element. A frame (Fig. 2, not shown), including the parts 8, 9 shown in Fig. 3, fits around the element and is secured to the appliance in which the motor is mounted. The part 2 of the element restrains and heavily damps radial vibrations of the shaft and the parts 3, 4 resiliently isolate (but without substantially damping) tangential vibrations of the bearing housing.
