  • Patent number: 10323690
    Abstract: A lubricating oil passage portion that constitutes a cooling portion is exposed to the outside from a casing. Lubricating oil having absorbed heat of a thrust bearing portion and a journal bearing portion is cooled in the cooling portion, when the lubricating oil moves from an upper oil chamber to a lower oil chamber while circulating by use of gravity. Thus, the circulating lubricating oil prompts cooling of the heated thrust bearing portion and journal bearing portion. Additionally, the lubricating oil passage portion of the cooling portion is provided integrally with the casing, on the radially outer side of the casing.

  • Patent number: 8230835
    Abstract: Emergency lubrication systems and methods for an engine are provided. One system includes a primary lubrication system including a de-aeration oil tank configured to store de-aerated oil until the oil is de-aerated, a first oil supply line configured to provide de-aerated oil to the engine, and a first valve configured to control the flow of oil through the primary lubrication system. The system further includes a secondary lubrication system including a second valve coupled to the de-aeration oil tank and configured to control the flow of oil through the secondary lubrication system, and a second oil supply line coupled to the engine and to the de-aeration oil tank via the second valve. One method includes the steps of detecting a predetermined event in the engine, preventing the aerated oil from entering the primary lubrication system, and using the aerated oil in the secondary lubrication system to lubricate the engine.

  • Patent number: 7997385
    Abstract: The present invention is to provide a machine tool in which appropriate warm-up operation can be performed. Unnecessary warm-up operation before machining is not carried out and damage of bearings caused by the warm-up operation is prevented. A controlling unit stores data of a supply amount of lubricant to bearings and a rotation speed of a main spindle in a memory unit as time-series data. When rotation of the main spindle is started, the time-series data stored in the memory unit is used to calculate an amount of remaining lubricant in the bearings and determination of necessity of warm-up operation is made based upon the stored data. A rotation speed at a start-up time of the main spindle is controlled according to the determination result.

  • Patent number: 7975805
    Abstract: A system for lubricating a lubrication target located within a refrigerated atmosphere. The system includes a lubricant source, a pressurized air source, and at least one pneumatically-activated pump in connection with the lubricant and air sources. The pump output is connected to a conduit that terminates at a spray nozzle for delivering the lubricant to the target in a controlled fashion. Pressurized air may be used to better control the lubricant delivery. The temperature of the lubricant and air flowing through the conduits is regulated so that the fluids will flow predictably at very cold temperatures.

  • Patent number: 7703577
    Abstract: A door hinge lubricator includes a tube, a wicking material and at least one attachment device. At least one lubrication opening is formed through a wall of the tube. Each lubrication opening could be a hole or a slot. The wicking material is inserted into an inner perimeter of the tube. The wicking material is saturated with a lubricant, such as oil. Each end of the tube is sealed with an end plug or the like. The at least one attachment device is preferably attached substantially in-line with the at least one lubrication opening. It is preferable to place the single attachment device on each end of the tube. The door hinge lubricator is attached to one of the hinge plates, adjacent the hinge pin. Lubricant will be wicked into the joints between the opposing hinge plates. After a door hinge stops squeaking, the door hinge lubricator may be removed.

  • Patent number: 7665513
    Abstract: A heat exchanger structure of an automatic transmission stabilizing a temperature of oil is provided. A heat exchanger structure of an automatic transmission includes an automatic transmission, a first heat exchanger provided on an upstream side and a second heat exchanger provided on a downstream side, each capable of cooling oil ejected from the automatic transmission, and a thermo valve capable of supplying oil subject to heat exchange by at least one of first and second heat exchangers to the automatic transmission. When a temperature of the oil is relatively low, the thermo valve supplies oil passed through the first heat exchanger to the automatic transmission and shuts off a flow of oil from the second heat exchanger to the automatic transmission. When a temperature of the oil is relatively high, the thermo valve supplies oil passed through first and second heat exchangers to the automatic transmission.

  • Publication number: 20080314572
    Abstract: An oil cooler for an engine or other lubricated mechanism includes a connector through which the oil cooler is connected to an oil supply passage and a return oil passage in an engine crankcase or other supply source. The connector includes a seal face to which inlet and outlet passages from the cooler are connected with oil supply and return passages in a connected mechanism. A continually open oil bypass is provided by forming a groove or slot in the seal face of the oil cooler extending between the inlet and outlet passages of the oil cooler and forming the cooler oil bypass. Alternatively, a bypass may be formed by a slot in a mating engine or mechanism connector connecting with the supply and return oil passages. Using a perimeter gasket between mating connectors can increase the bypass oil flow by the area of the clearance within the gasket opening created by the thickness of the gasket.

  • Publication number: 20080109129
    Abstract: The start control of the invention repeatedly performs a start-up process for a start of an oil pump, which pressure feeds the flow of oil in a motor cooling system, at the timings of rise in either of motor temperatures by every 10° C. from a preset initial starting temperature. This arrangement heightens the potential for a successful start-up of the oil pump even when the oil flow has a high viscosity due to a relatively low outside air temperature Tout. In the event of a failed start-up of the oil pump by repetition of the start-up process, the start control specifies the occurrence of an abnormality in the oil pump or in the power supply to the oil pump at the outside air temperature of not lower than a preset reference temperature, while not specifying the occurrence of an abnormality in the oil pump or in the power supply to the oil pump at the outside air temperature of lower than the preset reference temperature.
