    摘要： A rolling element bearing comprises an outer ring and an inner ring which enclose a bearing space containing rolling elements which are in rolling contact with the raceways of both rings. At least the contact surface layer of one of the rings and/or rolling elements consists of a zirconium material. At least one of the rings has a composite layered structure comprising an outer layer of steel facing away from the bearing space and an inner layer of a zirconium material.

    摘要： An improved immersible magnetically-coupled mixer has rollable bearings readily cleanable by flushing in place and easily removable and replaceable without damage to either the mixer impeller or the bearings. The rollable bearings are resistant to corrosion, capable of running without lubrication, and have low propensity for batch contamination through wear. The rolling and fixed elements of the bearings are impervious to attack by the process materials being mixed, the rollable elements, preferably balls, being formed of a hybrid ceramic such as silicon nitride, and the races being formed of either a nickel-beryllium or cobalt-chromium-tungsten alloy. A mixer impeller having a central bore is rotatably mounted on the rollable bearings on a fixed impeller shaft attached to the inner wall of a vessel at the bottom of the mixing space, which shaft extends through the impeller bore. The impeller contains magnets and is couplable in driving relationship to an external magnetic mixer drive. The impeller bore is larger in diameter than the fixed shaft, and two sets of rollable bearings are disposed between the impeller and the shaft. The bearings are exposed to the liquid in the vessel during agitation, and the impeller provides a continual flow of liquid across the bearing balls and races, preventing formation of stagnant areas of process materials within the mixer assembly and permitting cleaning of all mixer surfaces by flushing.

    摘要： A rotary vane compressor comprises a cylinder having two closed ends defining a cylinder chamber in which is rotatably mounted a rotor. The rotor carries a plurality of radially movable vanes which move radially into sliding contact with the inner surface of the cylinder chamber during rotation of the rotor to compress a refrigerant gas. The rotor is rotationally driven by a rotor shaft rotatably mounted by bearings in the cylinder ends. To prevent destruction of the ozone layer, a refrigerant containing no chlorine, such as HFC-134a (1,1,1,2-tetrafluoroethane; CH.sub.2 FCF.sub.3) is used, and to compensate for the inferior lubricating properties of the chlorine-free refrigerant, the bearings are provided with a manganese phosphate coating of 10 .mu.m-15 .mu.m thickness to prevent cohesion and seizure of the mutually contacting surfaces of the bearings and rotor shaft.

    摘要： A method of making a shaped part having members that are positively interconnected via thermal treatment. The shaped part includes a metallic member having a first flange that is delimited by an outer contour of the metallic member and projects essentially at right angles therefrom. The first flange defines a recess-like opening having a base in which is provided a circumferential groove that extends essentially parallel to the first flange. A second flange is formed between a base of the groove and a contiguous surface of the metallic member. Prior to creation of the positive interconnection between the metallic member and the ceramic member, at least the metallic member is heated up, and then the ceramic member is introduced into the recess-like opening of the metallic member.

    摘要： Improved structures in bearings operable to receive and support shafts or members which are supported for rotation on shafts or pins are disclosed. In one form, just the inner cylindrical surface of a solid bearing made of metal or hard ceramic material is coated with a synthetic diamond material deposited in situ therein as carbon atoms by means of high energy radiation, which also serves to form synthetic diamond structures of layers of such carbon atoms so deposited. In another form, the entire race of a multiple part bearing is coated with synthetic diamond material. In a third form, a rolling member type bearing, such as a ball or roller bearing, is provided containing an inner race, an outer race, and a plurality of balls, rollers, or other rolling members supported between the inner and outer race. In certain instances, the rolling members are retained by means of a cage supported therebetween. The rolling members, inner and outer races, and, when employed, the cage, are all coated with hard synthetic diamond material deposited in situ thereon as described. Alternatively, select portions of the components of the bearing may be coated to the exclusion of other portions thereof. In all forms, the synthetic diamond material coating may be overcoated with thin layers of chromium, chromium alloys, or similar materials.

    摘要： A rolling bearing has races and a rolling element. At least one of the races and the rolling element is made of a carburized or carbonitrided alloy steel. The content of a fine carbide present in the surface layer of the one element of the rolling bearing is 20-50 vol %. The content of retained austenite in the surface layer is 10-25 vol %. The rolling bearing provides a long-life rolling bearing suitable for use in a transmission and engine.
