A chainsaw, a lubrication system for a chainsaw, and a lubricant for a chainsaw are provided. The chainsaw includes a lubrication system and guide bar extending from a housing. The lubrication system includes a reservoir at which a lubricant is contained. The reservoir is releasably attachable to a machine drive device. The machine drive device includes a body at which a pump apparatus is positioned. The machine drive device forms an inlet opening in fluid communication with the reservoir. The machine drive device forms an outlet opening at which a conduit is fluidly coupled to receive the lubricant. The conduit forms a conduit outlet through which the lubricant is provided to the guide bar.

A lubricating system has a pump to force a viscous lubricant from a supply of lubricant to a lubricator at which the lubricant is to be dispensed onto a cable, wire, or the like that is being pulled through a conduit. A sensor, associated with a spool from which the cable is being dispensed, is be used to automatically control the amount of lubricant that is to be dispensed onto the cable. A second described system comprises a custom bucket or bucket insert which allow a cable to pass through the bucket whereupon lubricant will be automatically applied to the cable and the container includes a profiled base to ensure proper passage of the cable through the lubricant and ensure the maximum usage of any lubricant.

A pump system for supplying lubricant to components of a wind turbine comprises: a pump for pumping lubricant through a fluid circuit of the wind turbine; a drive means for driving the pump; and, a gearbox arrangement arranged to couple the drive means to the pump. The gearbox arrangement comprises a rotatable input shaft configured to be driven by the drive means and a rotatable output shaft configured to drive the pump. The input shaft is rotatable in a first direction of rotation and a second direction of rotation when driven by the drive means. The output shaft is rotatable in the first direction of rotation, and the speed of rotation of the output shaft is determined by an operational mode of the gearbox arrangement. In a first mode of operation, when the input shaft rotates in the first direction of rotation at a first speed of rotation, the gearbox arrangement is configured to drive the output shaft to rotate also in the first direction of rotation at the first speed of rotation. In a second mode of operation, when the input shaft rotates in the second direction of rotation at the first speed of rotation, the gearbox arrangement is configured to drive the output shaft to rotate in the first direction of rotation at a second speed of rotation.

An oil supply system for supplying oil to a lubricating cavity of a gas turbine engine, the oil supply system has: a de-oiler having a de-oiler air-oil inlet, a de-oiler oil outlet hydraulically connected to the lubricating cavity, and a de-oiler air outlet in fluid flow communication with an environment outside of the oil supply system; and a closed-loop oil circuit including a main pump having a main pump inlet and a main pump outlet, the main pump outlet hydraulically connected to the lubricating cavity, a de-aerator having a de-aerator inlet hydraulically connected to a scavenge outlet of the lubricating cavity, a de-aerator air-oil outlet in fluid flow communication with the de-oiler inlet, and a de-aerator oil outlet hydraulically connected to the main pump inlet.

A lubrication system includes a lubricator. A detecting unit includes an oil introducing part, multiple chambers, multiple blockage detectors and a processor. The oil introducing part is connected between the detecting unit and the lubricator. The oil introducing part communicates with the chambers. The blockage detectors are electrically connected to the processor and monitor transportation status of lubrication oil of the chambers. The processor judges the transportation status of the lubricating oil of the chambers by results from the blockage detectors. The lubrication system finds out blockage in the oil paths immediately so as to remove the blockage timely.
