Abstract: A toothed plate-link chain that is employable in a vehicle drive train or other drive systems, in which rocker joints formed of link plates and rocker members are designed so that in spite of a requisite free play in the joint, protection against twisting of the rocked members is improved while at the same time noise is reduced. Additionally, no particular orientation of the rocker members relative to link plate openings is needed when assembling the rocker joint. The contours of each rocker member are formed mirror-symmetrically both to the X-axis and to the Y-axis.

Abstract: A toothed plate-link chain composed of a plurality of interconnected plates that form chain links. The chain links are hingedly interconnected to adjacent links by transversely-extending hinge pins. A least some of the links include outer guide plates having convexly-curved ends that are so configured that the ends of adjacent guide plates contact each other when the chain is at a predetermined limiting angle of deflection during a swing-back mode, which deflection direction is in a direction opposite to the direction of deflection of the chain as it passes around a toothed wheel. The limitation of chain deflection during a swing-back mode serves to limit the frequency and amplitude of strand oscillations and thereby reduces the noise that would otherwise result from strand oscillations.

Abstract: A plate-link chain having a plurality of link plates hingedly connected with each other by pairs of rocker members that each include two rocker members. The rocker members extend transversely to the longitudinal direction of the plate-link chain and are situated with play in openings in the link plates. The rocker members and the link plate openings each have respective curved contact surfaces along which the rocker members and the link plates bear against each other to transmit force. The rocker members include curved rolling surfaces along which the rocker members roll against each other during chain operation to transmit force. The play value between the rocker members and the opening in an adjacent link plate is less than 0.2 mm to minimize lateral vibrations of the chain during operation, to prevent contact of the chain with an enclosing housing and thereby reduce emitted noise.

The link plate openings have at least three inwardly extending, convexly curved regions.

Abstract: A toothed plate-link chain including plate sets of toothed plates as well as at least one guide plate. The guide plate which is positioned within a plate set, or as a lateral end plate, and is carried on two chain pins that pass through openings in the guide plate as well as opening in the toothed plates. The guide plate has a wing that in the running direction, or opposite to the running direction, of the toothed plate-link chain extends beyond a plate tooth of a toothed plate in the same plate set.

Abstract: A plate-link chain, in particular a toothed plate-link chain, is composed of adjacent plates and opposing plates that form chain links by sets of the link plates. One or more spacer elements are installed between adjacent link plates to enable assembly of a wider chain at a reduced chain weight as compared with a chain in which additional link plate sets are installed to increase the chain width. The spacer elements have openings to receive hinge pins that pass through the link plates. The openings of the spacer elements can include pairs of openings, a single oblong opening, or openings that include gaps to enable assembly of a spacer element in a manner similar to a spring clip.

Abstract: A plate-link chain composed of a plurality of plates that form plate sets, which are connected to an adjacent plate set with a hinge joint.

Abstract: A conical disk array for a belt-driven transmission having sets of conical friction disks on the input and output sides that are operatively coupled to each other by an endless torque-transmitting means to transmit torque. At least one friction disk of the conical friction disk sets has a friction surface structure with ground grooves that are not coaxial with each other. A grinding device for grinding the friction surface has its axis of rotation skewed relative to the axis of rotation of the friction disk being ground. A method is for producing a friction surface structure on a friction disk of a conical disk array with a grinding device with which the rotating friction disk serves to form a non-coaxially-oriented friction surface pattern as the friction surface.
