Abstract: Since an oil level of oil in a first space housing a transmission mechanism is lower than an oil level of the oil in a second space housing a differential gear, not only is it possible to lubricate a drive pinion and a ring gear housed in the second space with a sufficient amount of oil while cutting the total amount of oil compared with a case in which the oil levels of the first space and the second space are both high, but it is also possible to reduce the resistance of oil to stirring in the second space by discharging excess oil building up in the second space to the first space via a second oil passage formed along an axial center of a pinion shaft, and to prevent the oil level of the first space from decreasing excessively, thus avoiding aeration of an oil pump.

Abstract: The machine tool lubrication device comprises connection means grippable automatically by a manipulator of the machine tool, lubricant dispensing means, and dispensing control means operable by the machine tool.

Abstract: A lubrication assembly is provided for lubricating a surface with a lubricant. The lubrication assembly includes a tube adapted to be coupled to the surface. The tube defines a reservoir for storing the lubricant thereon. The lubrication assembly also includes a wiper that is coupled to the tube. The wiper includes a first portion in fluid communication with the lubricant and a second portion disposed for continuous contact with the surface for automatically transferring and supplying the lubricant from the reservoir to the surface. The lubricant reduces frictional properties of the surface.

Abstract: A lubricator (28) is provided to lubricate tab stock (82) prior to forming the tab stock (82) into pull tabs. The lubricator (28) comprises felt pads (36-38) for removing contaminants from the tab stock (82) prior to lubrication thereof. A hydrostatic chamber (40) receives and disperses lube (42) from a source (44). As the tab stock (82) passes through the chamber (40) the lube (42) coats the tab stock (82). Subsequently, the tab stock (82) passes through wipers (50-52) and metering rollers (58-60) to remove all but a predetermined quantity of the lube (42). A collector (70) is provided to collect any excess lube (42) and return same to the source (44) through a return line (72) thus allowing recycling of the lube (42).
