Abstract
A “splash” lubrication system having an oil slinger capable of providing an increased flow rate of lubricating and cooling oil to lubricated components of the system compared to conventional dip stick oil slingers while reducing oil atomization and oil loss through the crankcase vent is disclosed. In embodiments of the invention, the oil slinger is comprised of a disk coupled to the crankshaft assembly of the device being lubricated (e.g., an engine, pump, compressor, or the like) so that rotation of the crankshaft assembly rotates the disk for splashing lubricating oil from the crankcase's oil sump onto the moving parts of the device being lubricated by the lubricating system.
Claims41
A lubrication system for a device having a crankcase housing a crankshaft assembly capable of rotation, comprising:
- an oil sump suitable for containing lubricating oil for lubricating moving components within the crankcase;
- and
- an oil slinger coupled to the crankshaft assembly so that rotation of the crankshaft assembly rotates the oil slinger for splashing lubricating oil from the oil sump,
- wherein at least a portion of the oil slinger is continuously submerged in the lubricating oil contained in the oil sump as it is rotated by the crankshaft assembly.
A lubrication system, comprising:
- an oil sump suitable for containing lubricating oil for lubricating moving components within a crankcase housing a crankshaft assembly so the crankshaft assembly is capable of rotation;
- and
- a disk coaxially coupled to the crankshaft assembly so that rotation of the crankshaft assembly rotates the disk for splashing lubricating oil from the oil sump,
- wherein at least a portion of the disk is continuously submerged in the lubricating oil contained in the oil sump as it is rotated by the crankshaft assembly.
A lubrication system for a device having a crankcase housing a crankshaft assembly capable of rotation, comprising:
- means for containing lubricating oil;
- and
- means, coupled to the crankshaft assembly, for splashing lubricating oil from the containing means,
- wherein at least a portion of the splashing means is continuously submerged in the lubricating oil contained in the containing means.
An oil slinger for a lubrication system, comprising:
- a disk suitable for being coupled to a crankshaft assembly so that rotation of the crankshaft assembly rotates the disk for splashing lubricating oil from an oil sump suitable for containing lubricating oil,
- wherein at least a portion of the disk is continuously submerged in the lubricating oil contained in the oil sump as it is rotated by the crankshaft assembly.
A device, comprising:
- a crankcase housing a crankshaft assembly capable of rotation;
- an oil sump suitable for containing lubricating oil for lubricating moving components within the crankcase;
- and
- an oil slinger coupled to the crankshaft assembly so that rotation of the crankshaft assembly rotates the oil slinger for splashing lubricating oil from the oil sump,
- wherein at least a portion of the oil slinger is continuously submerged in the lubricating oil contained in the oil sump as it is rotated by the crankshaft assembly.
A lubrication system, comprising:
- an oil slinger suitable for being coupled to a crankshaft assembly so that rotation of the crankshaft assembly rotates the oil slinger for splashing lubricating oil from an oil sump suitable for containing lubricating oil,
- wherein flow of the lubricating oil over the oil slinger as it passes through the oil sump is substantially laminar for inhibiting atomization of the lubricating oil.
