Abstract: The invention relates to an arrangement for transmitting torque between conical pulleys in a transmission mechanism. The invention is characterized in that the arrangement includes a first endless, flexible element (v-belt, chain or flat belt) for taking-up clamping forces and a corresponding second element for power transmission between the pulleys. The second element extends around the first element and is provided with devices which are in shape-bound engagement with co-acting devices on the first flexible element, the arc of contact (.alpha.) of which around the pulleys is greater than the arc of contact (.beta.) of the elements when in engagement together.

Abstract: A work conveyor sprocket and link assembly includes a sprocket having a body member. The body member includes a plurality of radially extending teeth connected by arcuate root portions. The body member further includes shoulder portions which extend outwardly from the sides of the body member. The link assembly includes a plurality of individual links connected to each other by link pins. Conveyor slats are secured to one side of the links; small flanges project from the other side of the links. Fasteners are connected to the flanges in order to retain the link pins in place. When assembled, the links engage both the teeth and the shoulder portions so as to distribute applied forces over a large area.

Abstract: A drive chain-sprocket combination comprising a chain constructed of alternate single toed or toothed links and links, similar to British Standard roller chain links, joined by pivot means meshing with sprockets formed of outer members and a central spacer of a second and lesser diameter having cavities matching the toes of the toed links. The outer members extend radially beyond the central spacer and provide rims which act as guides to maintain chain-sprocket engagement.

Abstract: This invention makes it possible to produce a chain having a particularly small overall width, while able to operate with sprockets having a customary tooth thickness. This result is obtained in particular by providing for the inner plates (10) to be deformed, in their end zones (12), on both faces and to delimit projecting portions (16c) directed towards the interior of the chain, these projecting portions thus being separated by a distance (d.sub.1) smaller than the thickness of the teeth of the sprockets with which the chain is to cooperate.

Abstract: A transmission chain for a conical disk transmission with intercoupled links receiving link pins of which the end surfaces bear against the disks, and in which the contact zones between the longitudinal sides of the pins and the links are shorter than the upright sides of the link openings and offset in longitudinal direction of the links with respect to the ends of these sides.

Abstract: The invention relates to a conveyor chain, which comprises chain links (1) consisting of a barrel portion (2) and elongated side bars (3,4), the first ends of which are attached to the ends of the barrel, whereby the distance between the free ends of the side bars (3,4) corresponds to the length of the barrel (2) including the side bars attached to it. In order to enable the assembly of a chain of identical, mutually similar parts without tools, the surfaces located opposite each other at the free ends of the bars (3,4) of the chain links are provided with studs (5,6), the outer diameter of which corresponds to the inner diameter of the barrel (2) and the elasticity of the bar (3,4) material is such that the bars can be spread from each other to such an extent as to enable the insertion of the studs (5,6) of one chain link into the barrel (2) of another chain link.

Abstract: A guide chain with supporting link chains including chain links which are connected by crosspieces. To limit the mutual pivot angle, each chain link is provided with slots which extend about a common pivot axis, with engaging studs of an adjacent chain link extending into the slots. In order to facilitate assembly and improve the support capability of the guide chain, each chain link is made as one piece, is provided at one end, on one side, with a disc-shaped plate in which are disposed the slots, and is provided at the other end, on the opposite side, with a cup, on the bottom of which are formed the engaging studs. The diameter of the plate is less than the diameter of the cup, so that the plate of one chain link can be placed into the cup of another chain link.

Abstract: A guide chain for guiding feed lines from a stationary connection to a movable consuming device. Separable cross pieces are provided which form through passages for the feed line. The cross pieces include cross bars and separating members which can be frictionally and positively interconnected. In order to improve the individual stability of the through passages to be adapted to the dimensions of the feed lines, the cross bars are provided on their inwardly directed wide sides with a mounting channel which has a C-shaped cross section for receiving a one-piece frame element or a segmented frame element, so that the through passages for the feed lines can be selectively formed by the separating members, or by the frame elements, or by a combination or separating members and frame elements.

Abstract: Bicycle Chain is made of alternating bushing links and pin links. The bushing links have parallel bushings held in interference fit in bushing plates and extended axially beyond the bushing plates, solid metal rolls with a lubricating plating are held loosely on the bushings, and loosely between the bushing plates. The bushings extend axially outward beyond the bushing plates for substantial distances. Pins extend through the bushings and are fixed in pin plates to form pin links which alternate with the bushing links. The pin plates are held outward from the bushing plates for a substantial amount by the axial bushing extensions to prevent dirt build up. The pin plates, bushing plates and bushings are plated with an anti-corrosion plating. The pins and rolls are plated with a porous metal plating with solid polymeric lubricant held within pores of the plating for lubricating the pin-bushing interior interface and for lubricating the roll-bushing and roll-bushing plate interfaces.

Abstract: A power transmission roller chain link construction comprises a first link pin plate with a pair of spaced apart substantially parallel link pins secured to said plate in a press-fit so that they extend parallel to the plate. A bushing is fitted over each pin and a roller link plate is press-fitted on the bushing adjacent each of its ends. A roller is rotatably mounted on each bushing between the roller link plates. The link pins, link pin portion and a rod portion extending outwardly from each link pin portion beyond the second link plate, the second link plate being press-fitted to the link pin adjacent their opposite ends from the first link plate. The rod portion of each link pin has a threaded area adjacent the second link plate and a nut is threadably engageable on the threaded area. The link is manufactured by first press-fitting the link pins to the first pin link plate thereafter assembling the bushing with the roller link plates at each end over the pin and assembling a bushing between the plates.

Abstract: The sprocket drive chain of this invention is particularly adapted for right angle drive but may also be used for straight or various other angular drive situations. The construction lends itself to ease of manufacture and especially for the automated manufacture of chain. In the preferred embodiment the chain comprises interlocked links rotatably coupled, such as by a pin and bushing combination, with stamped side plates to provide an intermediate tooth (sprocket) opening. The successive openings are adapted to receive a tooth at opposite 90.degree. angles thus readily being adapted to a right angle drive. Other embodiments employ a common pivot to support the side plates in successive 90.degree. opposite directions, and a single plate version useable with a slotted tooth sprocket.

Abstract: A replaceable wear cover for track chain bushings which covers and protectively shields the track bushing such that the wear cover, rather than the bushing, directly engages the metallic outer radial portions of the chain-driving sprocket wheel. The wear cover may be made of heat treated steel or like material for long life and includes noise suppression and impact absorbing elastomeric members for reducing noise and impact resulting from driving engagement with the sprocket wheel. A mounting portion of the replaceable wear cover is attached to the inner surface of the track plate by one or more fasteners that pass through the track plate and wear cover mounting portion or by using the same fasteners which attach the track plate to the track links. The wear cover includes a shield portion having depending legs for covering the standard track bushing and which are sprung apart for installation or removal, thereby insuring a tight fit on the bushing.

Abstract: A stiffening arrangement for an endless chain which is constructed of a plurality of interleaved sets of links joined by pivot means which comprises an elongated stiffening member retained in grooves formed in chain side links and which contacts the tops of the links in the chain.

Abstract: A drive sprocket wheel of the type having drive chain link receiving pockets formed between the sprocket teeth and a circumferential groove dividing each tooth into a pair of tooth sections with the outer tips at the flanks or sides thereof being cupped for the reception of the horizontal chain links, is improved by sloping the cupped outer tips toward the running direction of the chain. In the sloping direction, the outer portions of the flanks may be flat and are followed by concave surfaces. The sloping flanks of each pair of toothed sections establish theoretical points of contact with the rounded horizontal chain links during the drive operation, such points lying about midway between opposite sides of the sloping flanks.

Abstract: A chain mechanism composed of a main chain provided with triangular links disposed at a certain pitch interval and formed with a pivot apart from the joints of the chain and an auxiliary chain having the same pitch and pitch number as the main chain and provided with triangular links which are arranged in opposite relationship to the triangular links of the main chain and formed with a pivot located identically to the triangular links of the main chain, the joints and pivots of both chains being coupled through coupling links and support links which are equal in effective length. The main chain, auxiliary chain, support links and coupling links can form an associated continuous parallel crank mechanism cooperatively and therefore, the support links as well as coupling links maintain a predetermined angle throughout the path of the chain mechanism.

Abstract: Links for steel sprocket chains are each formed of a pair of dodecagon shaped broadened portions joined by a web with parallel sides. When cut from a sheet metal plate the boundary edges of the broadened portions and web of one link are in contact with and at least partially congruent to adjacent links.

Abstract: An endless standard link chain closed with a quarter- or half-turn twist to increase the contact length by a factor of four or two, respectively, and thus extend its life when used on power drives utilizing sprockets capable of engaging standard link chains.

Abstract: A T-headed pin for use in rivetless chain, generally of the trolley conveyor type, is disclosed. The pin can entirely replace the conventional forged pin of any ordinary size and has superior design matching abilities. It is unique in that it is constructed entirely from a flat piece of sheet metal. Rectangular metal blanks with paired oppositely projecting tabs are provided. The blank is first curled to form the body of the pin with the tabs projecting endwise therefrom. In automated manufacture of chain of the type mentioned in selected lengths, the links may be readily assembled with curled pins having tabs projecting axially from both ends. The tabs may then be bent as required to complete the chain length. Alternatively, the tabs at one end only may be bent and lengths of chain may be readily assembled by inserting the other end of each pin into place and then bending the tabs at said other end.
