ENGINE COMPONENT STACK AND ASSEMBLY THEREOF
Aspects of the disclosure are directed to components of an engine and one or more methods for assembling the components. A first component is positioned adjacent to a second component such that a first surface of the first component abuts the second component. A cooling plate is coupled to the first component such that a first surface of the cooling plate abuts a second surface of the first component. A loading ram is coupled to the cooling plate such that a second surface of the cooling plate abuts the loading ram.
BALL BEARING CAM FOLLOWER FOR AN ADJUSTABLE AIRCRAFT SEAT
A cam follower assembly includes a ball bearing having an outer ring and an inner assembly which includes two or more segments. The inner assembly is disposed in the outer ring with a full complement of balls disposed therebetween. The outer ring and inner assembly each include a race having a gothic arch cross sectional configuration that causes the balls to roll on two portions of each race.
METHOD FOR PRODUCING A PLAIN BEARING BUSH
The invention relates to a method for producing a plain bearing bush (4) whereby a flat supporting metal layer (8) is provided, an anti-friction layer (9) is provided on this supporting metal layer (8) to produce a flat composite material, and the flat composite material is then rolled into the shape of the plain bearing bush (4) in such a way that the supporting metal layer (8) in the plain bearing bush (4) is disposed radially underneath the anti-friction layer (9). The invention further relates to a plain bearing bush (4) produced by this method.
INDUCTION HEATING PLATE
An induction heating device providing a support plate with an upper surface for receiving a side face of a bearing. A plurality of concentrically arranged induction coils provided at an underside of the support plate, and connected to and selectively powered by a generator. Temperature sensors arranged on the upper surface of the support plate at different radial distances from a center axis of the concentric coils. A control unit receives and monitors a temperature signal from each of the temperature sensors, which receives and processes a signal indicative of a load on each coil, when selectively powered, to identify a first coil that is electromagnetically coupled to an inner ring and a second coil that is electromagnetically coupled to an outer ring. The control unit configured to select a first and a second temperature sensor associated with the first and second coils respectively, and to execute a heating cycle.
BEARING THERMAL RELIEF FAN DRIVE GEAR SYSTEM ASSEMBLY METHOD
A method of assembling mating components includes the steps of heating an inner surface of a first cavity of a first part to generate a first expansion, heating an outer surface of a component surrounding an outer periphery of the first part to generate a second expansion of the component that corresponds to the first expansion of the first part, inserting a second part into the first cavity while the first part is in an expanded condition, and cooling the first part to contract around the second part.
INDUCTION HEATING DEVICE
An induction heating device comprising at least one induction coil mounted to a support frame. The support frame is adapted to travel on a surface of an annular metal article to be heated and comprises a wheel set having one or more driven wheels. The support frame is adapted to travel on a side face of the annular metal article and is provided with first guide and second guide elements, which are respectively configured to engage with an outer circumferential surface and an inner circumferential surface of the annular metal article to ensure that the support frame travels on a circular path during use of the device.
Bearing thermal relief fan drive gear system assembly method
A method of assembling mating components includes the steps of heating an inner surface of a first cavity of a first part to generate a first expansion, heating an outer surface of a component surrounding an outer periphery of the first part to generate a second expansion of the component that corresponds to the first expansion of the first part, inserting a second part into the first cavity while the first part is in an expanded condition, and cooling the first part to contract around the second part.
ESP Motor Radial Bearing Anti-Rotation Tab Retention
Rotor bearings for ESP motors can include anti-rotation tabs configured to engage with a stator during assembly of the ESP motor. Prior to insertion of the rotor bearing within the stator, the anti-rotation tabs may be held in place within axial slots in the outer surface of a bearing bushing of the rotor bearing using retention rings. The retention rings and the bearing bushing may be configured to allow for interference fit, as disclosed herein, which may be particularly useful for ceramic bearing bushings.
Bearing liners for use within light alloy housings
A device with a rotating element includes a housing body formed from a light alloy, wherein the housing body has a housing body thermal expansion coefficient, a bearing liner formed from a liner material disposed within the housing body, wherein the bearing liner has a bearing liner thermal expansion coefficient, and a bearing to support the rotating element with an outer race, wherein the bearing has a bearing thermal expansion coefficient, the outer race is press fit within the bearing liner, and the bearing liner thermal expansion coefficient is lower than the bearing thermal expansion coefficient.
Press-fit bearing locking system, apparatus and method
A press-fit bearing locking system, apparatus and method is described. A press-fit bearing locking system includes a diffuser having a diffuser groove on an inner diameter (ID), a bushing comprising an outer diameter (OD) press-fit into the grooved ID of the diffuser, the OD of the bushing having a bushing groove tracing a path of the diffuser groove, and a high thermal expansion material (HTEM) key seated within the bushing groove. A press-fit bearing locking method includes seating a HTEM key inside a groove on an OD of a bushing, press-fitting the bushing with HTEM key into a diffuser such that the bushing groove is opposite a groove on an ID of the diffuser, operating an electric submersible pump assembly including the diffuser during a temperature rise, and allowing the HTEM key to expand into the diffuser groove during the temperature rise to lock the bushing against the diffuser.
