A reduction gear includes a sun pinion and planet pinions driven by the sun pinion and rolling on a fixed ring gear. The device includes an oil tank, an oil supply duct and oil routing ducts. The device also includes an oil ejection device at the end of the fixed supply duct, the orientation of which includes a radial component directed away from a common axis of rotation, and a cylindrical device for recovering the oil that can move in rotation about the common axis of rotation. The oil ejection device is linked by at least one duct to a lubrication device for the gear formed by the cooperation of the teeth of at least one planet pinion with an adjacent pinion. This device feeds the ducts which supply the oil to the parts to be lubricated, by virtue of the action of the centrifugal field.

This invention provides a lubricating system for a gear train including: a lubricating oil supply port configured to supply a lubricating oil in a direction vertical to both axes of a pair of gears and toward a mesh point at which the pair of gears are meshed with each other; a shroud configured to cover at least teeth of the pair of gears so as to form a flow passage of the lubricating oil between the pair of gears and the shroud; and a pair of discharge ports respectively configured to discharge the lubricating oil from the flow passage. The pair of discharge ports are respectively positioned at two portions of the shroud respectively opposed to the mesh point across respective axes of the pair of gears.

A vehicle final drive includes a fixed spindle about which a wheel hub is mounted for rotation by wheel bearings, and within which a park and service brake assembly is mounted including a stack of Belleville springs carried by an input quill mounted within an inner end region, and a disc brake pack mounted within an outer end region. Located in the hub outboard of the spindle is a two-stage planetary reduction transmission. A reaction plate is fixed to an outer end face of the spindle cylindrical portion and holds the disc brake pack and a hub of a double ring gear of the transmission in place and preloads the wheel bearings. A fluid distribution manifold is defined by a passage in the spindle for distributing flow for cooling and/or lubricating an input thrust bearing, input drive shaft coupling splines, the brake disc pack, the wheel bearings, and the first stage planet gear bearings.

A cooling system for the gear case in the ranging arm of a longwall shearer, the ranging arm including a plurality of single gears mounted in a row within an elongated housing. The cooling system includes a coolant injection system in each of the single gears, each coolant injection system including a longitudinal opening in the gear axle, and a coolant injection tube mounted inside the longitudinal opening. The coolant injection tube has a diameter smaller than the diameter of the longitudinal opening. A coolant supply line is connected to and in communication with the coolant injection tube, and a coolant outlet is connected to and in communication with the longitudinal opening adjacent the one end of the longitudinal opening, so that coolant leaving the end of the coolant injection tube travels back along the coolant injection tube and then out of the gear axle thereby removing heat from the single gear.

A lubricating structure for a static hydraulic continuously variable transmission includes a central oil path axially formed at a center of a shaft of the transmission. A circumferential oil path is arranged at an inner circumferential part of a retainer between the retainer and an outer circumferential part of the transmission shaft. A diametrical oil path is in communication with the circumferential oil path and the central oil path of the shaft of said transmission. The diametrical oil path is provided with an orifice. A lubricant oil ejection hole is arranged at the retainer to eject lubricant oil from the circumferential oil path.

摘要:
The input rotational speed of a belt-driven conical-pulley transmission is determined by measuring a wheel rotational speed and the transmission ratio and by calculating the input rotational speed therefrom. In order to ascertain the slipping of a CVT transmission, the rate of change in the transmission ratio is drawn upon, or an acoustic parameter of the transmission is used. In the fluid control system, a valve is used whose opening cross-section is controlled according to the one differential pressure. In order to oil the conical discs, injection holes of an injection tube are used that passes through a slot provided in a slide rail resting against a strand of a flexible torque transmitting member of a conical disc flexible drive.

There is described a helicopter having a first member movable with respect to a second member; lubricated supporting means for supporting the first member with respect to the second member; and a primary lubricating circuit for lubricating the supporting means and in turn having primary storage means for accumulating a lubricating fluid, and primary fluid feed means for feeding the lubricating fluid to the supporting means; the helicopter also has an auxiliary lubricating circuit supplied continually by the primary storage means with a first lubricating fluid flow value, and itself continually supplying the supporting means with a second lubricating fluid flow value lower than the first value, so as to produce an auxiliary storage volume of lubricating fluid for use in the event of breakdown of the primary lubricating circuit.

The initial rotational speed of a conical disc flexible drive transmission is determined by measuring a wheel rotational speed and the gear ratio and by calculating the initial rotational speed therefrom. In order to ascertain the slipping of a CVT transmission, the rate of change in the ratio is drawn upon or an acoustic parameter of the transmission is used. In the fluid control system, a valve is used whose opening cross-section is controlled according to the one differential pressure. In order to oil the conical discs, injection holes of a injection tube are used that passes through a slot provided in a slide rail resting against a side of a flexible drive means of a conical disc flexible drive means.
