Abstract: A lubricant scavenging system for a turbine engine having a pair of concentric, counter-rotating shafts. The system comprises a lubricant sump housing having a radially inner surface, a pair of pedestal mounts each adapted to receive a bearing assembly from a respective shaft, a lubricant collection point axially disposed between the pedestal mounts, and a pair of axial channels adapted to guide lubricant toward the lubricant collection point.

Abstract: A plug for restricting a flow of fluid within a passageway having an interior surface with a predetermined inner diameter is provided. The plug includes a plate member having an outer edge and a rim bounding the outer edge of the plate member. The rim extends generally normal from the plate member. The rim has a contact portion and an indented portion. The contact portion contacts the interior surface of the passageway to retain the position of the plug within the passageway. The indented portion is spaced apart from the interior surface on the passageway to allow fluid to bypass the plug when the plug is located within the passageway.

Abstract: A lubrication system for an electrodynamic machine including therein an internal oil sump and at least one oil ring hydrodynamic bearing, wherein the oil ring is in fluid communication with oil, in the sump and replenishes oil in the bearing. The lubrication system includes an electrically powered oil sump pump that is oriented within the sump. An of intake is coupled to the pump and is in fluid communication with oil in the internal sump. An oil discharge line is coupled to the pump discharge. The distal end of the discharge line is oriented proximal the motor bearing, so that oil discharged therefrom replenishes oil in the bearing and shaft journal interface. The lubrication system oil discharge parameters are independent, of the motor speed, load or physical orientation, and may be varied by a controller coupled to the oil sump pump.

Abstract: A bearing lubrication system in which a shaft is journaled for rotation in an integral bearing in a gear box, the bearing being primarily loaded through less than its full circumference, leaving an unloaded reach of the bearing, the bearing being interrupted through a substantial arc in at least a portion of the unloaded reach to define a gap in the bearing through which lubricant travels, is provided with a fixed scoop for channeling lubricant into the gap. The bearing is a solid bearing, of a piece with a gear box housing, as is the scoop.

Abstract: A housed bearing assembly suitable for use as a pillow block bearing unit or flanged bearing unit. The assembly includes a shaft sleeve and roller body secured to one another and enclosed by a housing. The roller body is adapted to roll against an inner peripheral surface of the housing. A supply of lubricant sufficient to lubricate the roller body is contained within the housing. The housing and rolling body are designed to direct lubricant toward fluid tight areas of the assembly and away from those areas where leakage might occur. A lubricant containment reservoir is formed in either the housing or the shaft such that lubricant will not reach the space or interface between the shaft and the housing. The roller body may be provided with a drip edge to further direct lubricant away from the interface between the housing and the shaft. The housing is constructed as a spherical segment seated in a spherical seat to allow pivoting of the inner housing portion to pivot to adjust for misalignment.

Abstract: A side channel pump is disposed on the same shaft as a combination friction bearing, each conveyor blade having a cutout at the height of the side channel equivalent to and corresponding with the cross section of the side channel.

Abstract: A rotary impeller pump having a permanent magnetic drive is disclosed. An impeller disposed on a rotating shaft which is supported by a bearing assembly within a housing assembly. The bearing assembly is supported by a fixed ring assembly having a channel disposed therethrough, with one open end of the channel terminating above and adjacent the bearing assembly. A scoop wheel is disposed to rotate with the impeller and shaft. The scoop wheel raises fluid from a location below the bearing assembly to a location above the bearing assembly and adjacent a second open end of the channel. During normal operation, the housing assembly is substantially filled with the fluid medium to be pumped, and the fluid medium provides lubrication and cooling for the bearing assembly.

Abstract: A bearing device for a horizontal shaft type rotating machine includes an oil tank formed at the lower portion of the bearing box for storing lubricant oil for the bearing, the oil tank being divided by a bearing support plate between an oil feeding chamber and an oil collecting chamber; an oil feeding apparatus which pumps up the lubricant oil in the oil feeding chamber and feeds the lubricant oil onto the bearing; and a pair of diffusion flow passages; each of the pair of diffusion flow passages being formed along the inner wall of the oil tank and connects the oil collecting chamber with the oil feeding chamber; each of the diffusion flow passages permitting diffusion and movement of the lubricant oil from the oil collecting chamber to the oil feeding chamber.

Abstract: A bearing apparatus for a rotary machine having a horizontal rotating shaft comprises a bearing for supporting the horizontal rotating shaft, a bearing box for supporting the bearing therein, a lubricating oil tank disposed in a lower portion of the bearing box for storing lubricating oil, a lubricating supply device for picking up the lubricating oil in the lubricating oil tank and supplying the lubricating oil to the bearing, and oil guide device disposed beneath the bearing and allowing the lubricating oil discharged from the bearing to flow along a side wall of the bearing box to be stored in the lubricating oil tank.

Abstract: A jet spray slinger is provided for lubricating moving parts within a housing. A trough is fixed to or frictionally driven by a rotating shaft. The trough has holes that allow lubricant to be sprayed radially outward as the shaft rotates the trough. Axial holes in the trough or a deflector accomplish axial distribution of the lubricant.

Abstract: A scoop device for dividing oil in metered quantity in both directions from the scoop, in which the intake scoop passages deliver oil to a circumferential channel, from which it is discharged laterally into opposed grooves, the latter having notches in the outer sidewall thereof for metering the flow of oil from these grooves to the devices to be lubricated.

Abstract: The rotor of a thrust bearing for the horizontal shaft of a centrifugal pump is installed in a housing which is mounted in an oil-containing vessel and has an inlet below and an outlet above the oil level. The peripheral surface of the rotor has a groove which receives a portion of an annular stator to form a suction channel which draws oil from the vessel through the inlet when the shaft is driven. The oil fills the housing and is returned into the supply of oil in the vessel by way of the outlet, a cooling unit and a filtering cartridge.

Abstract: A device for transporting lubricant to the mechanical sealds in a submersible machine includes a funnel shaped guide means arranged on a rotating shaft in an oil room. Oil will be sucked in at the small end of the guide means and flow out at its big end thus obtaining a transport of oil.

Abstract: A pump has a rotating shaft supported by a pair of bearings. An oil sump is located below the shaft and contains oil for lubrication of the bearings. Roll pins are inserted into respective holes in the shaft to extend into the oil sump during rotation of the shaft to thereby throw oil for lubrication onto the bearings.

Abstract: A bearing, particularly a heavy duty bearing, in which lubrication is effected by lubricant being picked up on a disc (27,28) mounted on the bearing shaft (21), the disc having, at its periphery, an axially extending ring (35) on the inner and outer surface of which the lubricant forms a film. During start-up, lubricant on the outer surface is scraped off by an external scraper (57) and falls under gravity onto the bearing surface and as the speed increases, lubricant on the inner surface is picked up by a scoop (38,39) to produce a pressure head sufficient to pump the lubricant to a reservoir from which it flows to the bearing surface under gravity. The lubricant is pumped to the reservoir through an external cooler (62) and an external filter (66).
