摘要:
Die Erfindung betrifft eine Gelenkkette (GK), insbesondere für Fahrtreppen oder Fahrsteige, mit mindestens einem Krafteinleitungskörper (BU, ZB) mit einer nichtzylindrischen Kontaktfläche (F), an welcher ein Antriebskettenrad (AKR) kraftübertragend angreifen kann. Vorzugsweise ist die Kontaktfläche (F) eben oder zumindest abschnittweise gekrümmt und senkrecht bzw. schräg zur Laufrichtung der Gelenkkette (GK). Das Antriebskettenrad (AKR) enthält vorzugsweise kreiszylindrische drehbewegliche Zwischen körper (ZK) als Zähne.
摘要:
A chain belt for a continuously variable transmission which has a plurality of links and a plurality of coupling members which connect the plurality of links together. Each of the coupling members has a first end with a first bore and a second end with a second bore. A first retaining pin is fastened within the first bore of each of the coupling members and a second retaining pin is fastened within the second bore of each of the coupling members. The first and second retaining pins retain the plurality of links on the coupling member.

摘要:
A roller chain sprocket includes a body with a hub and a row of teeth that extends circumferentially around the hub such that the hub extends axially outward on opposite first and second sides of the row of teeth. The teeth are separated from each other by tooth spaces, wherein each of said tooth spaces is bisected by a radial tooth space centerline. First and second elastomeric cushion rings are respectively bonded to the hub on the opposite first and second sides of the row of teeth, with cushion ring extending circumferentially about the hub and including a plurality of compression pads separated from each other by axially extending transverse grooves. Each of the compression pads includes a planar or otherwise flat outer surface that is connected to a respective preceding one of the grooves by a leading corner surface and connected to a respective trailing one of the grooves by a trailing corner surface. Each of the grooves is located radially inward from a respective associated one of the tooth spaces such that the tooth space centerline is circumferentially aligned with the trailing corner surface that connects the groove to a preceding one of the compression pads. The compression pads provide both primary compression for a meshing chain link row and secondary compression for the next-meshing, upstream chain link row.

A bicycle chainring for engaging a bicycle drive chain has a plurality of teeth formed around its periphery. The plurality of teeth includes a first group of teeth, and a second group of teeth. The teeth of the second group are arranged alternatingly between the teeth of the first group. A portion of each tooth of the first group extends outwardly on a first lateral side of the chainring, and a portion of each tooth of the second group extends outwardly on the second lateral side of the chainring. Thus, each tooth is arranged in a laterally staggered position relative to its neighboring teeth. A bicycle chain drive employs the chainring. This construction of the chain drive and chainring offer the retention advantages of Narrow-Wide chainrings, but also allow the chain to engage with the chainring at multiple orientations.
摘要:
A chain link comprises a first plate having a first hole in it, a second plate having a second hole in it, a pin which passes through the first hole and the second hole, and a plurality of rolling elements arranged circumferentially around the pin, wherein when the chain link is engaged with a tooth of a sprocket, the tooth directly contacts one or more of the plurality of rolling elements. The plurality of rolling elements may roll along a surface of the tooth as the chain link conveys, or is conveyed by, the tooth. One or more of the plurality of rolling elements may roll along a surface of the pin as the chain link conveys, or is conveyed by, the tooth.
摘要:
Пластинчатая цепь, содержит пластины (1, 2) и шарниры, при этом шарнир цепи содержит валик (3), втулку (4) и упругий элемент (5), соединяющий валик со втулкой. Возможны варианты исполнения цепи в которой упругий элемент (5) выполнен из пластика, или составным, или из резины. Пластинчатая цепь может быть выполнена в виде втулочно-роликовой цепи. Пластинчатая цепь с упругими элементами может быть выполнена без втулок. Пластинчатая цепь может быть выполнена в виде двурядной или многорядной цепи.
摘要:
A chain has inner and outer links pivotally interconnected by transverse pins. In a straight configuration the links are substantially aligned in a linear direction. At least one resilient elongate flexible member is threaded along at least part of the length of the chain between the pins in alternate directions so as to force adjacent links of the chain to articulate out of the straight configuration. A chain in this form may be proof loaded before service by applying a tensile load and the elongate flexible member may be removed. A chain assembly comprises a plurality of said chains running between first and second connection brackets.

A low friction joint apparatus for chain links is provided. The apparatus may include a first link pin rigidly coupled to a first chain link, a second link pin rigidly coupled to a second chain link, a sprocket roller coaxially and pivotally disposed about the second link pin, a plurality of radial bearings radially disposed between the second link pin and each of the first link pin and the sprocket roller, and a plurality of axial bearings axially disposed between the second link pin and the first chain link, and between the sprocket roller and the second chain link. The second link pin may be coaxially and pivotally disposed about the first link pin. The sprocket roller may be rotatable relative to each of the first and second chain links.
