Abstract:
The beads of a beaded conveyor belt for a curve conveyor are constituted by a number of bead constituting bodies (2b) that are disposed over the entire periphery of the outer surface along the outer peripheral edge of a belt main body (2a) and that are narrow in the direction of the length of the belt. Further, the beads of a beaded conveyor belt for a linear conveyor are constituted by a number of bead constituting bodies (7b) that are disposed over the entire periphery of the outer surface along opposite side edges of a belt main body (7a) and that are narrow in the direction of the length of the belt. The conveyor belt is installed taut between straight type end rollers (15), and the width of the bead constituting bodies (2b, 7b) lengthwise of the belt is set at about 20 − 60% of the diameter of the straight type end rollers (15). Even when the conveyor belt is installed taut between small−diameter end rollers, long−term use is possible.
Abstract:
A curved conveyor, comprising an end roller (15) having a pivot shaft (15a) and a plurality of short rollers (15b) rotatably inserted onto the pivot shaft (15a), wherein bearings (15c) having outer races larger in outside diameter than the short rollers (15b) or bearings (15c) having outer races with the same outside diameter as the outside diameter of the short rollers (15b) are installed between the short rollers (15b, 15b) adjacent to each other at least on a belt outer peripheral side, whereby frictional sound from the end roller produced by the rotating driving of the conveyor belt can be suppressed.
Abstract:
Conveyor belt with edging comprising a bead part (13) engaging the belt (10) only locally of the edge (12) of the belt and having mutual mechanical interference fit (16/17) adjacent said belt edge (12). Typically, the edging extends inboard of the belt by less than 2.5% of the belt width and is of or for the longest and outermost edge of a corner or curve conveyor to serve for at least support, guiding or location purposes.
Abstract:
Endless belts having driving surfaces comprising a high temperature flexible thermoplastic composite, which belts exhibit reduced noise, reduced frictional heat generation, improved dimensional stability and improved abrasion resistance compared to known belt constructions. More particularly, an endless toothed belt having a high temperature-, abrasion- and noise resistant cover element, and which comprises from about 60 percent to about 100 percent by weight of the composite of a high temperature flexible thermoplastic material and from about 0 percent to about 40 percent by weight of the composite of a frictional modifier system, and methods for constructing such belts. Such belts include elastomeric body portions which may preferably be formed from suitable polyurethane materials.
Abstract:
A belt assembly for belt turn conveyor includes a belt with a plurality of longitudinal fibers generally aligned or oriented along the curved longitudinal axis of the belt. The belt may comprise a plurality of belt segments which are interonnected to form a endless belt with each belt segment preferably including a plurality of longitudinal fibers aligned along the longitudinal axis of each respective belt segment. When interconnected, the longitudinal fibers of each belt segment generally align along the curved longitudinal axis of the belt. Alternately, the belt may be woven such that the longitudinal fibers are substantially aligned along the curved longitudinal axis of the curved belt. Thus, a belt assembly for a belt turn conveyor is provided that exhibits a more uniform stiffness along its length, which results in the belt assembly exhibiting reduced forces across its length thus increasing the belt`s capacity and longevity.
Abstract:
The invention concerns a conveyor belt (1) comprised of a load-carrying side (2) and backing side (5) made of elastomer material as well as a traction support area (3) made of steel cables or cords (4) located between the load-carrying side and the backing side. In one variation, the backing side (5) consists of an outer wearing coat (6) which has a rebound resilience of at least 70 % and of an intermediate layer (7) between the traction support area (3) and the wearing coat, where a reflector (8) is present within the intermediate layer. In a further variation, the backing side consists of a wearing coat which also has a rebound resilience of at least 70 %, with a reflector within the intermediate layer, but without an intermediate layer between the traction support area and the wearing coat. In both variations, the reflector (8) is advantageously arranged in direct proximity to the traction support area (3), where the width (b) of the reflector takes up a maximum of 80 % of the entire width (a) of the conveyor belt, at an essentially equal distance (c) from the outer edges.
Abstract:
The invention concerns an apron conveyor (10) consisting of a supporting frame (118) with first and second essentially vertically oriented guidance surfaces (140a) and with first and second essentially horizonatlly oriented additional guidance surfaces (164, 165), an endless revolving belt (112) supported by the supporting frame (118) that has elements cooperating with the vertical guidance surfaces (140a) for holding the belt (112) on the supporting frame (118), and a long guidance element (148) of low-friction and flexible material arranged on the belt (112) which prevents vertical movement of the belt (112) in collaboration with the horizontal guidance surfaces (rails 164, 165).
Abstract:
In order to create a track link for tracked crawlers, for example a cranked-link model, endless conveyor chains, for example a non-cranked link model, or similar track types, wherein the compresssive forces occuring under designated operating conditions are broken down as much as possible into force vectors that are directed radially to the running surface of the track link or radially to the running surface of the idler or of the support and track roller, or directed to the track interior, but not to the outer edges of the track link or of the running surfaces of the idler or of the support and track roller, it is proposed that the contour of the running surface of the link (3) or of the idler or of the support and track roller, in the cross section of the head of the running surface perpendicular (90 DEG ) to the running direction, describes a nonlinear function, preferably a convex or concave arched compound curve relative to the overall running surface, which corresponds to or at least approaches an optimally stable and/or wear-resistant roller surface geometry. The form of the running surface head or the running surface contour is designed to be self-setting on the basis of the physical principle of least constraint in a normal operating movement between a track link (3) and a corresponding roller surface, for example a track roller, for a sufficiently long duration of movement.
Abstract:
A process and a device enable tubular straps to be pulled or guided through support roller stations. The strap (5) is rolled until the diameter (D) of the roll is less than the operating diameter (D') and is held in this position by a clamping means which moves with it, such as a mesh sleeve (4). The desired diameter of the strap is obtained by means of a device (2) whose diameter decreases like that of a nozzle.
Abstract:
A belt (1) for an endless belt conveyor of the type having a pair of cables or like flexible elongated elements supporting the belt therebetween. The belt (1) comprises a central portion (11) and two longitudinal side portions (12) each having a thickened bead (13). Each bead is provided with a longitudinal bore (15) extending therealong to receive a one of the cables. Each bead is also provided with a slit or other means to provide an opening (19) extending both outwardly through the bead from the bore and along the length of the bead through which opening the cable can pass. A retaining means (21) is provided for releasably retaining together the portions of the bead on the opposed sides of the slit. The retaining means may be in the form of interlocking male and female elements (23 and 25) respectively. Also disclosed is an endless belt conveyor fitted with an endless belt of the construction described.
