Oil supply device for an epicyclic reduction gear set

A bowl for supplying oil to at least two oil-distribution circuits which are connected to a planet carrier of an epicyclic reduction gearbox, the planet carrier rotating and the oil coming from a fixed oil ejector, the bowl being designed to be secured to the planet carrier and having a substantially cylindrical shape and being open radially towards the inside with respect to an axis. The bowl is divided into a circumferential succession of separate cups each designed to communicate with one of the oil distribution circuits A reduction gearbox with its supply device and a method of operation in a turbomachine are also disclosed.

LUBRICATION OF BACKS OF CAMS BY OIL RECOVERY

A valve actuating device includes a camshaft, a cam, and a lubricant conducting device. The camshaft has an oil supply duct extending in a longitudinal direction of the camshaft and a discharge orifice extending in a radial direction of the camshaft and in fluid communication with the oil supply duct. The cam is fixedly mounted to the camshaft to rotate with the camshaft, the cam having a contact surface and a lateral wall facing in an axial direction of the camshaft towards the discharge orifice. The lubricant conducting device is arranged to direct oil over the lateral wall of the cam towards the contact surface.

CONSTRUCTION MACHINE

Provided is a construction machine allowing a deck to be compact while facilitating water supply to a urea tank and access to a grease supply device. The construction machine includes a hose reel for grease supply disposed on a front-side portion of a deck of an upper slewing body, and a urea tank 30 disposed rearward of the hose reel on the deck and stores urea water for exhaust gas purification. The urea tank has a front surface provided with a water inlet for resupplying urea water. The hose reel is disposed deviated from the water inlet widthwise of the upper slewing body. The water inlet has a distal end located on the front side of a rear end of the hose reel.
