摘要： A chain drive mechanism includes a chain extending around a drive sprocket and a driven sprocket for transmitting torque therebetween. The chain drive mechanism also includes a snubber including one or more guide shoes, each having an engagement surface that contacts a side of the chain between the drive sprocket and the driven sprocket. The engagement surface of the guide shoe defines a recess with an opening therein, with the recess configured to convey lubricant fluid, such as oil, from the chain and through the opening by motion of the chain along the engagement surface. The recess has a wedge shape including two side walls converging toward the opening, and a floor that slopes downwardly away from the engagement surface and toward the opening. The snubber includes one or more guide shoes that are inside, outside, or some combination of inside and outside of the chain.

摘要： A lubricant cartridge container includes a cylindrical member, and a moving member moving inside the cylindrical member toward a lubricant inflow portion side as a fluid lubricant flows toward the lubricant inflow portion side when subjected to a suction force from a lubricating pump side. The moving member has a first moving main body portion moving inside the cylindrical member and contacting with a shoulder portion, and a second moving main body portion contacting with the lubricant inflow portion after the first moving main body portion comes in contact with the shoulder portion. The second moving main body portion has a center portion contacting with the lubricant inflow portion, and a step portion connecting the center portion and the first moving main body portion. The center portion has a recess recessed in a polygonal shape formed by connecting a plurality of apexes in a plan view.

摘要： A turbomolecular pump has a housing, a rotor shaft supported by a plurality of bearings for rotation relative to the housing about an axis of rotation, a deflector, a lubricant supply system and a lubricant transfer device provided on the rotor shaft. The bearings include a rolling bearing 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.

摘要： An example lubrication system for a rotating component has a primary lubrication system providing continuous lubrication during normal operation of the rotating component and secondary lubrication system with a reservoir co-rotating with the component. The reservoir is continuously replenished from the primary lubrication system during normal operation of the rotating system, with the lubricant being forced through a discharge orifice by the centrifugal force generated by the rotation toward, for example, a bearing or a gear. When the primary pressurized lubrication system fails, lubrication will continue to be provided by the lubricant in the supplemental lubricant reservoir while the rotation speed or power supplied to the shaft is controllably decreased in an emergency.

摘要： A bowl for supplying oil to at least two oil-distribution circuits which are connected to a planet carrier of an epicyclic reduction gearbox, the planet carrier rotating and the oil coming from a fixed oil ejector, the bowl being designed to be secured to the planet carrier and having a substantially cylindrical shape and being open radially towards the inside with respect to an axis. The bowl is divided into a circumferential succession of separate cups each designed to communicate with one of the oil distribution circuits A reduction gearbox with its supply device and a method of operation in a turbomachine are also disclosed.

摘要： Provided is a construction machine allowing a deck to be compact while facilitating water supply to a urea tank and access to a grease supply device. The construction machine includes a hose reel for grease supply disposed on a front-side portion of a deck of an upper slewing body, and a urea tank 30 disposed rearward of the hose reel on the deck and stores urea water for exhaust gas purification. The urea tank has a front surface provided with a water inlet for resupplying urea water. The hose reel is disposed deviated from the water inlet widthwise of the upper slewing body. The water inlet has a distal end located on the front side of a rear end of the hose reel.

摘要： A work vehicle having a joint, a joint sensor, a lubricant reservoir, a pump, and a controller. The joint has a first member connected to a second member by a bearing. The joint sensor is configured to provide a joint signal indicative of at least one of a position, velocity, and acceleration of the joint. The pump is configured to dispense lubricant from the lubricant reservoir to the bearing when actuated. The controller receives the joint signal, determines a cumulative bearing travel based on the joint signal, determines a bearing lubrication value based on the cumulative bearing travel, and actuates the pump based on the bearing lubrication value.
