  • Patent number: 4098396
    Abstract: A joint for connecting together adjacent ends of individual elongate pans of an armoured scraper chain conveyor, has the adjacent conveyor pan ends provided on the outsides of their sidewalls with interengaging male and female formations, each formation being provided with one or more abutment surfaces forming part of a laterally open pocket connected to a laterally open channel, the pocket and channel of adjacent pan ends receiving a common, laterally inserted connector having a shank portion located within respective channels and at each end of the shank portion an enlarged head located within respective pockets so as to be engageable with an abutment surface of a respective pocket, and an aperture provided in the shank portion to receive a locating pin restrained from lateral displacement by engagement with a projection of one or other of the formations.

  • Patent number: 4086012
    Abstract: A rotational energy absorbing coupling for shaft-to-shaft and shaft-to-crank applications such as a tiller arm for a steerable strut for hydrofoil ship using a plurality of shear pins spaced in a circular pattern. A first, inner disc is affixed to one shaft and has a circular repeating sequential pattern of a round hole, and a plurality of slots of increasing length all chamfered at the edges. At least a second disc or outer disc are connected to the other coaxial shaft or crank with extended arms and, when more than one is used are sandwiched over the first disc. These discs have a circular pattern of round holes chamfered at the edges and in register with the holes and the center of the slots of the inner disc. A plurality of axially aligned shear pins pass through all the aligned holes thus providing progressive bending of the shear pins due to the chamfered holes, then the shearing of the pins when an overload occurs.

  • Patent number: 4074946
    Abstract: A coupling for two members such as a shaft and a compressor rotor or a turbine rotor carried thereby in which it is necessary that the rotor be firmly and tightly fixed with respect to the shaft at all times and in which the rotor and shaft may be subjected to widely different temperatures at any one time. On one of the members, usually the rotor, there are provided three fingers or projections extending toward the other member, while the other member is provided with recesses to receive and fit such projections. The projections are wedge shaped with side plane surfaces parallel to a radius extending from the axis of rotation so that the portions of the members carrying the fingers and recesses can move radially simultaneously outwardly or inwardly relative to one another as one expands or contracts more than the other, without tightening or loosening the coupling.

  • Patent number: 4058023
    Abstract: A rotating assembly for material handling equipment such as a cast sprocket ring member and a cast hub member each equipped with bolt openings extending parallel to the axis of rotation, the bolt openings being equipped with spherical zonal surfaces and the bolts being equipped with spherical nuts to permit non-axial disposition of the bolts while the same are essentially under only tension.

  • Patent number: 4053248
    Abstract: A coupling flange on a torque transmitting shaft or the like for coupling in face-to-face relationship with a counter-flange has at least two tooth systems on its coupling surface and each system comprising a plurality of substantially parallel axially projecting teeth having inclined flanks. At least one tooth in each tooth system has a different height, spacing or shape from the other teeth in the tooth system and the tooth systems are engagable with a complementary configuration on the counter-flange so as to connect nonrotatably the flanges.

  • Patent number: 4017196
    Abstract: A union for connecting cylindrical members has mating concentric truncated conical surfaces on annular flanges. Tubular spring pins driven into aligned assembly holes passing through the two flanges secure the union together. An alternate embodiment includes an intermediate body which may be flexible. TOGETHERThe present invention relates to coupling means designed to connect members together The term "member" here being considered in its broadest sense.To ensure the coupling between two members, connecting means are used which bring into action assembling members of the screw or bolt type intended to connect the members together directly or to connect said members and an intermediate element which may or may not be subjected to one or more elastic deformations.

  • Patent number: 3985000
    Abstract: A joint inserted between a driving member and a driven member, such as a pair of substantially coaxial shafts or a shaft and a flywheel, comprises a stack of annular steel foils each having an even number of peripherally equispaced webs which are alternately secured to the two members via respective pairs of screws. The webs are interconnected by integral strips in the form of outwardly and/or inwardly bulging lobes enabling relative angular and radial shifting of the two members without exertion of a significant axial force upon them. The screws pass through mounting holes in the webs whose distance from the stack axis is greater than half the maximum radius of the foils.

  • Patent number: 3955654
    Abstract: A hydraulic retarder for braking a shaft has a rotor comprising a rotor shell mounted on the shaft end and rotatively movable relative to a stator shell forming part of a stator enclosing the rotor. The shaft end projects from a housing upon which the stator is mounted by an apertured structure surrounding a driving pulley mounted on the shaft end. The apertured structure comprises lugs on the housing and a toothed ring on the stator, the teeth in the ring co-operating with the lugs so as to hold the stator centred on the axis of the shaft end irrespective of the angular position of the stator. Recesses between the teeth of the ring are disposed and dimensioned so that they provide the necessary openings for moving an endless belt into or out of the structure simply by moving the stator through an angle.
