A feed system for feeding lubricating oil to members of a turbine engine including a reduction gearbox, the feed system including a nonpositive-displacement pump device for connecting upstream to an oil tank and driven in rotation at a speed that is not correlated with an operating speed of the turbine engine; a separator node connected to the outlet of the nonpositive-displacement pump device; a first delivery branch for lubricating the RGB connected to the nonpositive-displacement pump device via the separator node; a second delivery branch for lubricating other members connected to the nonpositive-displacement pump device via the separator node, the second delivery branch including a positive-displacement pump; and at least one fluid metering device having a metering slot fed by the nonpositive-displacement pump device via the separator node for the purpose of feeding the RGB.

A method for determining lubricant consumption by a transmission mechanism disposed on a machine tool includes steps of: a) estimating, based on an operational speed and a predetermined first predictive model, a total operational physical quantity; b) estimating, based on an individual operational physical quantity and the total operational physical quantity, a total operational count; c) receiving actuation information from the machine tool, and calculating a partial operational count based on the actuation information; and d) calculating, based on the partial operational count and the total operational count, a ratio between an amount of lubricant consumption within a time period and a total amount of lubricant.

An axle assembly having an axle housing with a center portion defining a sump and one or more axle shaft housings extending from the center portion. Each of the axle shaft housings receives an axle half shaft. The axle housing includes a differential assembly having a ring gear; and a lubrication directing assembly disposed directly adjacent to the ring gear. The axle assembly also includes a pump mounted in one or more of the axle shaft housings and is drivingly coupled to a pump gear. The pump gear is drivingly coupled to the axle half shaft. The axle assembly also includes an axle housing cover surrounding the axle housing. A fluid storage tank is attached to the housing cover, wherein the fluid storage tank includes a fill channel directly attached to the housing cover.

An improved, lightweight gear drive having a rim gear mounted on a shaft, the shaft formed of one or more shaft segments, each of the shaft segments supporting a segregated arc. The segregated arcs forming a circumferential portion of a bearing surface of the shaft.

The lubrication system includes a hydraulic cylinder pump which receives oil from the pile driver gearbox and an actuating mechanism connected to the pump to move oil therein through an exit line to a spray mechanism in the gearbox housing, providing lubrication to the gearbox bearings before the gearbox elements begin to operate.

A mixing machine includes a head extending over a bowl receiving location, the head including a downwardly extending rotatable output shaft for receiving a mixer tool. A drive train including a motor having an output operatively connected to drive a planetary gear system that effects rotation of the rotatable output shaft about its axis and orbiting of the shaft axis about another axis. A control system includes a master control unit and a slave control unit, the master control unit connected with a first sensor located along the drive train between the motor and the planetary gear system, the slave control unit connected with a second sensor, wherein both the slave control unit and the second sensor rotate with a part of the planetary gear system, wherein the master control unit and the slave control unit are configured for wireless communication with each other.

A filling and draining device for filling lubricant into and draining lubricant out of a housing (1), having a lubricant line (2, 21, 22) through which the lubricant passes into the housing (1), during filling, and through which the lubricant passes when the lubricant is drained from the housing (1). The housing (1) has a valve (6) through which the lubricant flows during filling and draining such that, for filling, the valve (6) adopts a first aperture width for the lubricant and, for draining, the valve (6) adopts a second aperture width for the lubricant.

A lubricating system includes a machine configured to operate in a first operating state and a second operating state; and a heat activated polymer material applied to at least a part of the machine and to remain solid during the first operating state and to soften upon being heated in the second operating state to lubricate the machine. The heat activated polymer material may soften due to increased friction incurred by the machine in the second operating state. A heating element may be operatively connected to any of the machine and the heat activated polymer material. The heat activated polymer material may soften due to being heated by the heating element in the second operating state. An injector may apply the heat activated polymer material to the machine. A channel may direct a flow of the heat activated polymer material as it softens in the second operating state.
