Title: An improved method of producing supporting rings for ball bearings
IPC: B21K1/04
Filed: 1960-12-12
Abstract: 924,443. Ball-bearings. EISENWERK ROTHE ERDE G.m.b.H. Dec. 12, 1960 [Dec. 12, 1959], No. 42721/60. Class 12 (1). [Also in Group XXII] A method of producing light metal alloy supporting rings for ball-bearings provided with steel races is characterized in that a ring blank consisting of a ductile light metal alloy, having a uniform cross-section all round, is heated to above the solidus point of the alloy and, after quenching, is clamped in a device in which it is expanded all round uniformly to above a stress value at which it undergoes a permanent increase in diameter. A ring blank 7, Fig. 2, or 8, Fig. 3, of an alloy of Al, Zn, Mg and Cu having 0.5 to 1.5% Cu, is made by piercing a billet on a mandrel, and hot-rolling to form a seamless ring, then heating to 460‹ C., i.e. above the solidus, quenching in a salt bath for about twenty minutes and pre-turning to the desired cross-section. The blank 7 is then expanded by segments 11 urged outwardly by an expander cone 10 moved down by hydraulic or eccentric means. The blank 8 is expanded by hydraulic fluid under pressure supplied to an annular chamber 17 through bores 18. The expanded blank 7 or 8 is then heat-hardened and the blank 7 machined to form a supporting ring 2 or 3 and the blank 8 machined to form the supporting ring 1. The rings 2 and 3 are connected together and to a steel housing ring 23 by bolts 21 having a reduced shank portion 25 in the ring 3 so that in the event of heating, when the bearing expands more than the ring 23, the shank 25 may bend. The ring 1 is bolted to a steel housing ring 29 by a bolt 26 having a reduced shank portion 26a. The rings 1, 2 and 3 support balls running on wire race elements and guided in ball cages. In another embodiment, Fig. 5, a light metal alloy supporting ring 41 is bolted to a light metal alloy ring 42 in turn bolted to a light metal alloy ring 32. A steel housing ring 39 supports the ring 42 on a conical surface 45 so that when the bearing is heated differential expansion causes the conical surface of the ring 42 to slide against the action of springs 34. A supporting ring 30 bolted to a ring 32 has a conical face 44 bearing on a steel housing ring 36.

[Also in Division F4] A system for the illuminating of indicators comprises a closed light conducting circuit, a light source for introducing light into the circuit and indicia means associated with the circuit shielded from direct illuminations by the light source and rendered visible by the dispersion of light from the circuit. In its simplest form the system consists of a hollow sphere having light reflecting inner and outer surfaces mounted in an aperture in a panel and having a hole for the reception of a lamp bulb in the part behind the panel, the direct light being screened by an opaque panel inside the sphere. A diffusing coating bearing indicia is applied to the inner surface of the sphere in front of the panel. Fig. 5 shows a form in which a filament lamp 30 is mounted in an orifice in a rear panel 56 on both sides of which are electroluminescent elements 66, 68, the element 66 also serving as an opaque shield screening a first panel 58 bearing indicia 50 from direct light. The panels 56, 58 have bevelled edges 60, 62 to form reflecting surfaces and the surfaces of the panel 56 are provided with light-diffusing facets 70. Fig. 6 shows an embodiment having two front panels 82, 84, one behind the other, bearing different indicia and having different coloured filters 86, 88, e.g. red and blue at the edges. The rear panel is fitted with two lamps 72, 74, one lamp being tinted with red and the other with blue filter material so that selectively lighting one or other of the lamps causes the indicia on one or other panel to become visible. In further modifications: (1) the lamp or lamps may be mounted outside the panel; (2) the arrangement is combined with an edge lighted front panel by which additional indicia outside the area of the main panel may be illuminated; and (3) the front panel is surrounded by a crenellated cylindrical light shield, the enclosing casing carrying a castellated ring co-operating with this to form a dimming means.
