  • Patent number: 8449245
    Abstract: A vertically mountable shaft and bearing assembly includes a thermally insulated housing that protects the shaft, bearing(s), and lubricant from overheating due to a surrounding process fluid that is above 65° C. This allows a bearing to be located near the shaft's distal end, thereby reducing shaft and bearing size requirements. The housing also serves as a reservoir for bearing lubricant that can be cooled by a lubricant cooling system normally used for processes at much lower temperatures. The lubricant can be circulated by an impeller that is actuated by the shaft or driven separately. The thermal insulation, can include vacuum, air, and/or a thermally insulating material. Additional rolling element and/or journal bearings can be included. Lubricant within the shaft housing can be pressurized, for example by pressurized gas or by filling the lubricant above the surrounding process fluid level. The shaft can operate a process fluid pump impeller.

  • Patent number: 6502666
    Abstract: An engine lubrication system is provided which has an oil pump for supplying lubricating oil from an oil pan to an area that is to be lubricated, the oil pump being positioned outside-the-oil pan and driven by a camshaft. An oil passage formation member fitted to the lower face of an engine block so as to be housed in the oil pan, comprises an oil inlet passage for taking in oil from the oil pan to the oil pump and a relief valve for discharging excess oil discharged by the oil pump via an oil supply passage. When the relief valve opens, the excess oil is not directly discharged to the oil pan but is returned to the oil inlet passage from the oil supply passage via a connecting path. The space required for housing a vertical engine, and in particular in the vertical direction, can thus be reduced and the formation of bubbles in the oil inside the oil pan due to the oil discharged by the relief valve through the oil supply passage, can be prevented.

  • Patent number: 6371246
    Abstract: An oil pump for a lubricating system of an outboard motor is disclosed. The motor has a cowling defining an engine compartment, a water propulsion device, and a guide member having an upper surface and a lower surface, the guide member positioned in the cowling and generally dividing the engine compartment into an upper part and a lower part. An engine is positioned in the upper part of the engine compartment within the cowling and has an output shaft arranged to drive the water propulsion device. The lubricating system includes an oil pan positioned below the guide member and an oil passage leading from the pan through the guide member. The oil pump is positioned in the upper part of the engine compartment, but below the engine, and is driven by a lower end of the output shaft of the engine which extends below the engine, the oil pump having an oil inlet in communication with the oil passage through the guide member.

  • Patent number: 6363981
    Abstract: In the operation of wood cutting machines such as delimbing machines which use chain saw cutting devices, it is common to either position the lubricating oil reservoir above the chain saw cutting device to create a gravity-fed system or couple a pump apparatus to the chain saw cutting device. Both arrangements may limit the flexibility of placement of the components comprising the lubrication system. The present invention provides a lubrication system for a wood cutting machine in which a receptacle receives lubricating fluid from the reservoir by use of a source of supply pressure within the receptacle. A source of discharge pressure operates on the receptacle to transport the lubrication fluid to the cutting chain device.
