A wind turbine drive train component (22) comprising a rotating shaft (61) with a radial seal (50) is provided. The radial seal (50) comprises a stationary part and a rotating part. The stationary part comprises a ring (51) with an inner edge and an outer edge, the inner edge being configured for contactlessly surrounding the shaft (61). The rotary part comprising a disc (52), coaxially connected to the shaft (61) for rotation therewith and comprising a flange (53) that wraps around the outer edge of the ring (51). The radial seal (50) further comprises an annular air lock gap (55) for containing an amount of lubrication fluid (64) and thereby closing off the air lock gap (55) when the rotary part rotates at a rotational speed above a predetermined threshold speed, the annular air lock gap (55) being formed by an inner surface of the flange (53), an outer part of the opposing parallel surface of the disc (52) and the outer edge of the ring (51).

An arrangement includes a shaft, a bearing, and a structure fixed to a housing. The shaft is rotatably mounted in the structure fixed to the housing by the bearing, and a first gap extends between the shaft and the structure fixed to the housing. The bearing and the first gap are connected to each other in a lubricant-conducting manner via a cavity. The structure fixed to the housing forms a first sump for lubricant, and the first sump is configured to collect lubricant dripping from the first gap.

A proactive, prophylactic vehicle fluid capture system that embodies an inflatable air-diaper disposed under the engine. The inflatable air-diaper is deployed upon an indication of a sufficient crash event, wherein the deployed inflatable air-diaper catches the above-mentioned vehicular fluid prior to contact with the surrounding ground, thereby lessening the negative environmental impact and clean-up time resulting from the crash event. The inflatable air-diaper may deploy with peripheral sidewalls to facilitate the retention of the hazardous fluid on the inflatable air-diaper. The inflatable air-diaper is made of material adapted to absorb these hazardous vehicular fluids

The present disclosure discloses an oil-retaining mechanism, a valve structure, and a water outflow device. The oil-retaining mechanism comprises a valve body, a valve shaft, and a sealing member. The valve body comprises a motion cavity. The valve shaft is disposed in the motion cavity and configured to move axially. The sealing member is disposed between a cavity wall of the motion cavity and the valve shaft. At least one of the cavity wall of the motion cavity, the sealing member, or a connection portion of the motion cavity, the sealing member, and the valve shaft extends inward to define an oil storage groove. The oil storage groove comprises an opening. An inner side of the opening stores lubricating oil. The opening cooperates with and contacts the outer circumferential surface of the valve shaft. When the valve shaft moves in the motion cavity, the lubricating oil lubricates the valve shaft.

A relief unit that is attached to an attachment hole penetrating through a wall of a housing accommodating a power transmission mechanism of a robot together with lubricating oil in a sealed state, which includes a body that is provided with an attachment section attachable to the attachment hole and that forms a communication passage disposed at a position where an internal space of the housing and an external space are connected when the attachment section is attached to the attachment hole. An opening and closing mechanism that is provided in the communication passage, closes the communication passage in a sealed state when the opening and closing mechanism is closed, and that opens the communication passage when the opening and closing mechanism is opened. a catching part is disposed at an intermediate position of the communication passage that catches the lubricating oil.
