Abstract:
A gearwheel pair for a gear unit, comprising a first gear and a second gear, which can be meshed with one another, wherein the first gear consists entirely or partially of metal or plastic and the second spur gear comprises an outer part having a gear rim made of a first plastic and having a number of injection-molded portions, an inlay part made of metal, and a connecting part, which is arranged between the inlay part and the outer part and is made of a second plastic for the interlocked and/or materially-bonded connection of the inlay part and the outer part and further relates to the second spur gear per se, a gear unit having such a gearwheel pair, and a method for producing a second gear, which is used for such a gear unit.
Abstract:
A torque transmitting gear includes a steel toothed annular flange having gear teeth defined on a periphery of the steel toothed annular flange. A steel hub is coaxially aligned with the steel toothed annular flange. A web is formed from a web material having a density less than or equal to 3.0 grams per cubic centimeter. The web is fixedly attached to the toothed annular flange and to the hub for rotation together with the toothed annular flange and the hub. The gear is to operatively transmit a torque of at least 500 Newton Meters for at least 6 million revolutions of the gear. An overall mass of the gear is less than two-thirds of an overall mass of a same-sized all steel gear having a solid steel web with a solid steel web thickness at least one-third of a face width of the toothed annular flange.
Abstract:
A lock-up device for a torque converter transmits a torque from a front cover to an input shaft of a transmission. The lock-up device includes a clutch portion, a piston and hydraulic oil leading-out portion. The clutch portion is disposed between the front cover and a turbine, and includes at least one clutch plate. The piston is disposed to be axially movable and presses the at least one clutch plate toward the front cover so as to turn the clutch portion into a torque transmitting state. The hydraulic oil leading-out portion is mounted to a piston-side lateral surface of the front cover, and leads a hydraulic oil residing between the front cover and the piston to an oil discharge channel provided in the input shaft of the transmission by utilizing rotation of the front cover.
Abstract:
A belt conveyor comprising a foraminous conveyor belt wrapped around sprockets and a method for helping release products adhering to the conveyor belt. The belt has openings through its thickness and across its length and width that admit sprocket teeth. The whole depth of the teeth is greater than the thickness of the belt so that the teeth protrude past the conveying side of the belt and help release the products off the end of the belt by pushing the products away from, and breaking their adherence to, the conveying side.
Abstract:
In a method for producing a spur-cut gear wheel, a plurality of individual components are provided with at least one hub, a disk wheel and a ring gear. The individual components are subjected to at least partial mechanical soft machining and joined by using a welding method. At least the ring gear is hardened and hard machined. Before carrying out a grinding burn test by using the nital etching process, gaps present on the rear side in the area of the welds produced during welding are sealed by using a sealing material that is resistant to nitric acid.
Abstract:
A drive gear for a generally cylindrical imaging component. The drive gear includes a body for engaging the generally cylindrical imaging component; a cylindrical shaft attached to the body, the cylindrical shaft having an end surface; and three prongs extending longitudinally outward from the end surface.
Abstract:
In a method for manufacturing a multi-stage gear in which no gap is formed between a small-diameter gear and a large-diameter gear, there are included a first step of forming the small-diameter gear on an outer peripheral surface of a workpiece, a second step of forming a large-diameter gear part by plastically deforming an end portion of the workpiece to increase the diameter thereof, and a third step of forming the large-diameter gear by cutting the large-diameter gear part.

Abstract:
A welded hollow gear ring (160, 260, 360, 460, 560) with an outer (140, 240, 340) and an inner (155, 255, 355) periphery, which exhibits a gear structure (131-138, 231-238, 331-338, 331′-338′) on at least one periphery, as well as exhibiting at least one welding joint (151, 251, 351, 451, 551) which has been formed by flash butt welding. The gear structure is formed by rolling, machining, or by a combination of machining and rolling. The gear structure can comprise cogs or helical gears.
