Provided is a bicycle chain that enables easy maintenance. A bicycle chain 10 includes outer link parts 12 having a pair of outer plate parts 12a disposed opposing and spaced at a predetermined interval, inner link parts 14 having a pair of inner plate parts 14a provided inward of the pair of outer plate parts and disposed partially overlapping the pair of outer plate parts, connection pin parts 18 that penetrate through-hole sections 13 formed in a portion where the outer plate parts 12a and the inner plate parts 14a overlap for connecting the outer plate parts 12a and the inner plate parts 14a, and roller parts 16 disposed inward of the pair of inner plate parts 14a and rotatably axially about the connection pin parts 18. The connection pin parts 18 have a first pin part 20 including a recess 24 formed with a spiral thread, and a second pin part 22 including a protuberance 28 to screw into the recess in the first pin part 20.

A method for forming a laser-marked chain assembly. The method includes: coupling a plurality of chain links to one another for form a length of chain having a first and a second end; marking an outer plate of at least one of the plurality of chain links with a laser; and coupling the first and second ends to one another to form the laser-marked chain assembly.

A chain belt for a continuously variable transmission which has a plurality of links and a plurality of coupling members connecting the plurality of links together. Each of the coupling members has an outer perimeter, a first end with a first prepared surface, and a second end with a second prepared surface. The prepared surfaces extend a depth from the outer perimeter of the coupling member. A first retaining member is fastened to the first prepared surface of the coupling members and a second retaining member is fastened to the second prepared surface of the coupling members. The first and second retaining members retain the plurality of links on the coupling members.

A link unit includes two first chain plates and an assembling rod. Each of the first chain plates has a first inner end section, a first outer end section offset from the first inner end section, an inner surface facing the other one of the first plates, and an outer surface opposite to the inner surface. The first outer end section of each of the first chain plates is formed with a connecting hole that has a first hole portion, a second hole portion, and a neck portion located between the first and second hole portions. The assembling rod is inserted through the connecting hole of each of the first chain plates, and is prevented from moving past the neck portions of the first chain plates so as to be positioned in the second hole portions of the first chain plates.

An intermediate chain for drawing assemblies of drawing machines provided with at least one track having a plurality of contiguous links configured to act on a product being worked in order to draw it, is interposed between the corresponding track and support means of the track and comprises a plurality of contiguous links. Each of said links comprises an idle roll equipped with a through axial hole, a join pin and a connection element provided with a plurality of through holes configured to house at least said join pin. The connection element comprises two lateral support portions positioned in correspondence to axially opposite longitudinal ends of said idle roll, and a central connection portion, interposed transversely between the two lateral support portions and joined to both in order to reciprocally connect them, keeping them at a fixed and constant reciprocal distance and in a fixed and constant reciprocal position.

A drive system for a vehicle includes a chain ring and a drive chain. The chain ring has a plurality of teeth serially arranged and joined to one another. A first subset of teeth has a first outer face that applies a lateral pressure to a link of a drive chain in a first direction. A second subset of teeth has a second outer face that applies a lateral pressure to another link of a drive chain in a second direction. The teeth all have substantially the same width. The top surfaces of the teeth are offset from the centerline of the drive chain. The centerlines of the top surfaces of the teeth are arranged asymmetrically on one side of the centerline of the drive chain.

The invention relates to a bicycle chain (100) comprising an alternate succession of outer links (120) and inner links (130), connected to each other at respective end portions (120a, 130a) thereof. Each outer link (120) and inner link (130) comprises two respective plates (121, 131) arranged parallel and spaced apart from one another to define a housing space (120c, 130c) for a tooth of a sprocket or toothed wheel. Each plate (121) of each outer link (120) has, at a central portion (120b) thereof, a first thickness. Each plate (131) of each inner link (130) has, at a central portion (130b) thereof, a second thickness. Each plate of each outer link (120) and inner link (130) has, at said respective end portions (120a, 130a), a third thickness. Said third thickness is smaller than the sum of said first thickness and second thickness.

L'invention se rapporte au domaine technique des chaînes et, plus particulièrement, au domaine des chaînes de sciage. Elle concerne un élément modulaire présentant plusieurs variantes, puis la chaîne que l'on peut obtenir par montage itératif d'une pluralité de ces éléments. L'élément modulaire de chaîne (10) comporte un tourillon (13, 23, 33) et deux demi-maillons (11, 15) s'articulant sur ledit tourillon, par une extrémité intérieure (12) pour l'un des demi-maillons et par une extrémité extérieure (14) pour l'autre, caractérisé en ce que : - le tourillon (13, 23) est effectivement libre en rotation vis-à-vis du demi-maillon amont et du demi- maillon aval, - les zones de frottement (1, 2) sont dimensionnées pour rendre sensiblement égales les intégrales des pressions de frottement sur les surfaces de contact entre le tourillon (13, 23, 33) et chacun des demi-maillons qui s'y articulent, et - il comporte des moyens annexes aptes à éviter le glissement axial des tourillons lors du fonctionnement.
