Provided is an apparatus for supplying lubricant to a timing chain installed in an engine, the apparatus including an injection hole configured for injecting lubricant from an oil pump, and an inner cover having a guide groove configured to receive lubricant injected from the injection hole and guide the lubricant toward a engagement place between the timing chain and a sprocket, wherein the inner cover has a guide groove provided at a position facing an injection hole of a counter surface portion that is spaced apart from a cylinder block and faces the guide groove.

A harmonic reducer includes a shaft having a first through hole extending from a first end to a second end of the shaft; a wave generator arranged on the shaft and being rotatable along with the shaft; a flexible spline arranged around the wave generator; a circular spline arranged around the flexible spline; a first flange coupled to the shaft via a first bearing and coupled to the flexible spline; and a second flange coupled to the shaft via a second bearing and coupled to the circular spline. One of the flanges is arranged near to the first end of the shaft. A cavity is provided between the one of the flanges and the first end of the shaft, such that it is in fluid communication with an external environment via the first through hole.

An axle assembly having an axle housing, a dam, and a fastener. The dam is disposed in the axle housing and retains lubricant in an arm portion of the axle housing. The fastener that extends from the axle housing and engages a dam mounting feature of the dam to secure the dam to the axle housing.

Disclosed is a drive unit (10) with a housing (12), an electric motor (14) arranged in the housing with a rotor shaft (26). At least two oil chambers (30) are arranged in the housing (12). In each case the oil chambers include an oil zone (38) and an air zone (40) with an oil capture pocket (46). The oil chambers are flow-connected to one another via an overflow channel (42). Axial end areas of the rotor shaft (26) project into the oil chambers (30), and the rotor shaft defines a connecting channel (34) which flow-connects the oil chambers (30) to one another. A transmission is coupled to one axial end area or the rotor shaft (26) and an impulse disk (32) is coupled to the opposite axial end area, where each axial end area conveys oil to the respective oil capture pocket (46).

A transmission for an agricultural or heavy load vehicle is provided, and includes a central drive shaft, at least one planetary gearset comprising a planet carrier, at least one output drive element, and one brake device. The drive shaft is connected to the output drive element via the planetary gearset. The brake device is located between the planet carrier and the output drive element in the form of a ring gear, such that the output drive element can be coupled to the planet carrier via the brake device.

Embodiments are directed to solid lubricant assemblies for providing over temperature protection for bearings and gears in rotorcraft systems. A solid lubricant enters a fluid state above a certain temperature and is positioned so that fluid lubricant is applied to the bearings or gears.

A lubricating liquid manifold for a crankpin of an epicyclic gear train. The epicyclic gear train is lubricated by a lubrication system conveying a first flow of a lubricating liquid towards the manifold and a second flow of the lubricating liquid towards a member to be lubricated. The manifold comprises a hollow body provided with an inlet port intended to receive the first flow and an outlet port designed such that the first flow is conveyed towards a guide device connected to the crankpin. The manifold comprises a barrier comprising a shoulder connected to the body and a deflector protruding radially outwards from the body so as to form, with the shoulder, a diversion space for diverting the second flow and preventing it from penetrating into the manifold.

Example illustrations are directed to a differential, e.g., a disconnecting differential, and associated methods. A disconnecting differential may include two side gears configured to deliver torque from an output gear or differential casing to respective vehicle wheels when the differential is in a connected state. Each of the side gears may be configured to receive the torque from the output gear while permitting a differential speed between the side gears. The disconnecting differential may also include a disconnect device configured to disconnect the output gear from the two side gears such that the differential is in a disconnected state. The disconnecting differential may also include a position sensor configured to determine a rotational position of the output gear.

A vehicle drive-force transmitting apparatus including: a casing provided with an oil supply hole; a pump for pumping out an oil stored in the casing; and a pipe for delivering the oil pumped out by the pump, such that the oil discharged from the pipe is supplied to the oil supply hole. The oil is to be discharged from the pipe collides with an oil collision portion which is a portion of the casing and which is located on an upper side of the oil supply hole. The casing includes a guide portion and a block portion. The guide portion is located on a lower side of the oil collision portion, so as to guide the oil discharged from the pipe toward the oil supply hole. The block portion is located to surround the oil collision portion, so as to block the oil splashing from the oil collision portion.

A power transmission device for a work vehicle includes: a transmission case; a gear transmission contained in the transmission case and configured to receive motive power from a power source; a differential mechanism contained in the transmission case and configured to receive motive power from the gear transmission and transmit the motive power to a left wheel and a right wheel; and a gear cover covering a lower portion of a ring gear of the differential mechanism.
