ПОДШИПНИК И СПОСОБ ЕГО ИЗГОТОВЛЕНИЯ

FIELD: machine building. ^ SUBSTANCE: invention refers to rolling and sliding bearings of various mechanisms and machines, and also to separate components of machines - beads, rollers, bushings, axles and other components. The bearing consists of components made out of fibre material. Also as fibre material there are used multi-layer band or wire. Metal band or wire are in compacted and thermally toughened condition, while fibres are pressed between them by cold plastic deformation. Also here is disclosed the procedure for bearing fabrication consisting in forming components by means of winding rolled metal in several layers. Rolled metal is in thermally toughened and brittle-ductile condition. Plastic bend of rolled metal is performed before winding. Winding is carried out with tension of tensile stresses near elastic limit of rolled material. Upon or in process of winding the formed component is subject to expansion facilitating required density of fibres, specified shape and dimensions. ^ EFFECT: increased rigidity and durability of bearing components. ^ 2 cl, 6 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 391 568 (13) C1 (51) МПК F16C F16C F16C F16C B23K 19/02 33/58 33/61 33/64 20/00 (2006.01) (2006.01) (2006.01) (2006.01) (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21), (22) Заявка: 2009110865/11, 24.03.2009 (24) Дата начала отсчета срока действия патента: 24.03.2009 (45) Опубликовано: 10.06.2010 Бюл. № 16 (73) Патентообладатель(и): Королев Альберт Викторович (RU), Королев Александр Альбертович (RU), Королев Андрей Альбертович (RU) заключающийся в формировании деталей путем навивки в несколько слоев металлического проката.

Thermally isolated mechanical coupling - roller bearing is disposed between relatively non-rotatable components secured by setscrews

A thermally isolated mechanical connection between two machine parts comprises an angular contact roller bearing captive between two flanges raised on the machine parts and secured by a number of peripherally arranged bolts. The bolts are isolated from the flanges by thermally insulating inserts and little heat is transmitted across the bearing by virtue of the small contact area of the rollers. The bearing also serves to mechanically align the machine parts.

SOLIDS DIVERTER FOR A DOWNHOLE DRILLING MOTOR

SOLIDS DIVERTER FOR A DOWNHOLE DRILLING MOTOR A downhole drilling motor located near the end of a rotary drill string is operated by the drilling mud for driving a rotary drill bit to drill an oil or gas well or the like. Fluid lubricated bearings are employed and a portion of the drilling fluid is diverted through the bearings of the downhole motor with the balance of the drilling fluid being discharged through ports of the drill bit. The diverted portion of the drilling fluid is transmitted along a flow path that results in an abrupt change of direction of flow. The flow path will purge a portion of the drilling fluid of unwanted solids by diverting the solid along with the main portion of the drilling fluid through the motor and through and out of the drill bit. The entry of large contaminating solids or high-density and abrasive solids to the bearings is restricted. This prevents plugging of flow through the bearings and reduces wear in the bearings by reducing the volume of abrasive ...

Thrust distribution levers for extruder screw bearings - to minimise sepn. or maximise thrust for multiscren machines

In the support of a series thrust bearing mounted along a rotating shaft and riding on stationary bearing tracks mounted on a corresp. series of support plates, the mutual alignment and load-sharing of the support plates is ensured by pairs of rods mounted on a stack of balanced levers supported on opposite sides of an ancillary thrust plate. The plates are keyed against rotation by an adjacent rod. Alternatively, the thrust is transmitted down the root of the shaft via a series of split collars, each of which divides the thrust between the adjacent rotary bearing and the next stage of the shaft root by a ratio depending on the relative differences in the radial spacing of bearing rods on support faces of the collars from road acting as a fulcrum on the thrust faces of the collars. Used for supporting the thrust of screws for e.g. extrusion of plastics or rubber materials, esp. of multi screw machines with limited space between adjacent screw axes. Automatic thrust equalisation prevents ...

Wheel hub

The assembly comprises a hub and a homokinetic joint comprising a first tripod element connected to the hub and defining three trunnions on which are mounted three part-spherical rollers and a second element connected to a transmission shaft and defining three raceways in which the rollers carried by the tripod element are received. The hub defines a cavity in which is received at least partly this tripod element which constitutes a distinct part and is connected to the wall of this cavity by an auxiliary homokinetic coupling. The latter is capable of operating at a given angle which is added to the normal pivoting or break angle of the joint and consequently increases the maximum break angle of the joint.

METHOD FOR UNLOADING THE RINGS OF THE BEARING BEARING FROM ACTION OF CENTRIFUGAL FORCES (OPTIONS) AND THE ROLLING BEARING (OPTIONS)

1. Способ разгрузки колец подшипника качения от действия центробежных сил, заключающийся в создании сил, действующих на тела качения в направлении к оси вращения подшипника, в котором наружное кольцо выполняют из двух кольцевых частей, установленных с зазором между их боковыми внутренними поверхностями, а указанные силы создают механическим воздействием посредством давления на тела качения в стационарном режиме работы указанными двумя частями наружного кольца путем их поджатия к телам качения и контактирования их наружных дорожек качения с телами качения при установке подшипника в рабочее положение, что приводит к уменьшению максимального напряжения в кольцах подшипника, возникающего под воздействием центробежных сил тел качения, при больших частотах вращения вала. ! 2. Способ разгрузки колец подшипника по п.1, при котором углы контакта тел качения с указанными обеими частями наружного кольца приблизительно равны между собой. ! 3. Способ разгрузки колец подшипника по п.1, при котором углы контакта тел качения с указанными обеими частями наружного кольца не равны между собой. ! 4. Способ разгрузки колец подшипника качения от действия центробежных сил, заключающийся в создании сил, действующих на тела качения в направлении к оси вращения подшипника, в котором указанные силы создают механическим воздействием посредством давления на тела качения в стационарном режиме работы, по меньшей мере, двумя кольцами подшипника и контактирования их наружных дорожек качения с телами качения, по меньшей мере, одно из указанных колец действует путем поджатия к телам качения при установке подшипника в рабочее положение, РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2009 117 746 (13) A (51) МПК F16C 19/00 F16C 33/58 F16C 33/60 (2006.01) (2006.01) (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ЗАЯВКА НА ИЗОБРЕТЕНИЕ (21), (22) Заявка: 2009117746/11, 13.05.2009 A 2 0 0 9 1 1 7 7 4 6 R U Ñòð.: 1 ru A (57) Формула изобретения 1.
