A transverse bar for releasably connecting two side portions of a chain link of an energy guide chain, wherein at least at one or at both of its ends the transverse bar has a fixing region for releasably fastening to the respective side portion and wherein the fixing region of the transverse bar includes a locking element which is transferable into a locking position and an unlocking position, wherein in the locking position the transverse bar is non-releasably locked to the side portion and in the unlocking position the transverse bar is releasable from the side portion, wherein the locking element includes an actuating portion for selectively transferring same into its locking or its unlocking position, and a locking portion for locking engagement with the side portion. The locking element is in the form of a pivotal part and upon actuation of the locking element the locking portion is moved in a pivotal movement at least in a part of its movement from the locking position into its unlocking position or vice-versa.

A uniformly alloyed metallic member having an inertial amount of metallic alloy including at least one aperture, including an inertial amount visual indicator at least associated with the inertial amount of metallic alloy in terms of weight or mass, and including an alloy visual indicator at least associated with type of the metallic alloy.

A plurality of bistable compliant links are pivotally attached to one another, each of the links having a compliant section and first and second rigid sections extending from the compliant section. The links are pivotally attached to one another via the first and second rigid sections, such that when the links are pivoted with respect to each other past a threshold position toward a closed position, the links are biased toward the closed position by forces created by the compliant sections, and when the links are pivoted with respect to each other past the threshold position toward an open position, the links are biased toward the open position by forces created by the compliant sections. The forces created by the compliant sections biasing the links toward the closed position and biasing the links toward the open position are caused by elastic deformation of the compliant sections.

A silent chain includes a plurality of inner links, a plurality of outer links, and a plurality of rotation rods. The inner links are arranged along a transmission direction. At least one of the inner links includes an inner plate unit, and an inner chain body that is fixedly disposed on an outer side of the inner plate unit, that is made of a nonmetallic material, and that has an engagement protrusion protruding in an engagement direction. The outer links are spaced apart from each other along the transmission direction and are disposed on outer sides of the inner links. The outer links and the inner links are disposed in an alternating arrangement along the transmission direction. The rotation rods interconnect the inner links and the outer links in series so that each of the inner links is rotatable relative to each of two adjacent ones of the outer links.

An investment cast, stainless steel chain link for use a part of a chain. The chain link includes a pair of spaced first and second sidebars that each extend between forward and rear ends of the chain link. A reinforcing rib is formed on each sidebar and is flush with the forward and rear ends of the chain link. A barrel is formed at the rear end of the sidebars. The forward end of the sidebars includes either a first or a second attachment boss. The first attachment boss includes a pin head receptacle that allows the head of the chain pin to be flush with an outer surface of the first attachment boss. A retaining pin extends through the second attachment boss to prevent axial movement of the chain pin. In one embodiment, the chain pin is rotatable and, in another embodiment, the chain pin is prevented from rotating.

A chain with excellent wear resistance, which minimizes chain elongation, reduces vibration and noise, and improves drive efficiency; the chain includes at least a plurality of link plates and a plurality of pins as chain components. The pins and mutually sliding chain components sliding against the pins are formed with a hardened surface layer containing one of Cr carbide, Ti carbide, V carbide, Nb carbide, Cr nitride, Ti nitride, V nitride, and Nb nitride on part or all of respective sliding surfaces. In the case where the chain includes bushings as chain components and the bushings are the mutually sliding chain components, the bushings are formed with the hardened surface layer on part or all of their sliding surfaces.
