Abstract:
This invention provides a pin assembly that is self-lubricating and includes a pin, a pin insert that is received within the pin and a quantity of lubricating agent. The present invention also provides an insert for a pin that may be used in a pin joint that contains an automatic lubrication dispensing mechanism.
Abstract:
A lubrication system comprises an elevated reservoir with a gravity-operated lubrication distribution system that achieves economy, reliability and improved thermal capacity.
Abstract:
An oil supply system supplies oil under pressure to a bearing or journal enclosure during normal positive gravity conditions as well as negative gravity and zero gravity conditions. A closed oil storage tank containing a volume of oil below a gas filled headspace with primary drain in a bottom portion normally supplies a pressure pump which passes a pressure control valve before entering an inlet of the enclosure. In negative gravity or zero gravity conditions oil is absent from the tank bottom and the primary pressure pump is starved of oil. The invention solves this problem with an auxiliary tank outlet disposed above the bottom drain (at the top and/or sides of the tank) and the oil-air separator separates the air before pumping the oil under pressure to the bearing or journal enclosure past a directional switch. The directional control switch (1) connects the switch oil inlet to the switch oil return outlet and oil tank when oil pressure delivered by the pressure pump exceeds a predetermined minimum threshold pressure; and (2) connects the switch inlet to the oil supply outlet and enclosure when oil pressure delivered by the pressure pump is less than the threshold pressure.
Abstract:
The invention relates to a device with components concentrically disposed and rotational in relation to each other, wherein a rotational insert disposed in an external component having at least one seal with a sealed area acting upon an inner component is provided between said components. A lubricant reservoir connected by bores (13a, 13b, 13c), channels or the like to the sealed area is mounted in the area of at least one inner component (3, 4).
Abstract:
A turbomolecular pump has a housing (120), a rotor shaft (24) supported by a plurality of bearings (32, 34) for rotation relative to the housing about an axis of rotation (26), a deflector (40), a lubricant supply system (36) and a lubricant transfer device (38) provided on the rotor shaft. The bearings include a rolling bearing (32) that receives lubricant from the lubricant supply system to via the lubricant transfer device. The rolling bearing is disposed intermediate the lubricant transfer device and the deflector and the deflector is configured to deflect lubricant that passes through the rolling bearing outwardly with respect to the rotor shaft.
