Abstract: In a gear arrangement whose output shaft (5) is rotatably mounted in a gear box (6) and which corotates by means of a dog plate (3) via an axially interposed cushioning disk (2) with a gear (4) driven by a worm shaft (7) and, further, which output shaft is axially supported directly and/or indirectly, via the cushioning disk (2) and the gear (4), by the gear box (6), it is intended to provide, despite design related axial length tolerances, a tolerance play compensation in a manner which is considerably simplified from a production and assembly engineering viewpoint. Towards this end, the elastic cushioning disk (2) is provided with axially projecting spring lips (21 to 23), distributed over its circumference, for the development of a defined preloading pressure upon the components supported by the gear box (6).

Abstract: Several embodiments of coupling devices for marine outboard drives for providing a coupling between an engine output shaft and the outboard drive, drive shaft. Each embodiment employs as the coupling a first portion that provides a relatively resilient driving connection for absorbing low speed torque vibrations and a second more rigid driving connection for providing a more positive power transmission at high speeds and high loads. In some embodiments, the more resilient connection is provided by a spring which may comprise either a torsional spring or a torsional coil spring. In other embodiments, elastomeric elements provide the driving connection.

Abstract: A lubricant free low cost overload release clutch having a spring housing with an integral hub, a detector ring containing fixed detent bullets for engagement with springs in the housing on one side, and a bullet detent housing on the other side, together with spider cushion and shaft housing engaged for rotary turning with the bullet detent housing in response to the rotation of a shaft in the shaft housing. The release clutch responds to preset torque limits determined by spring tension. After a disengagement caused by excess torque, the clutch will reset by further rotation of the detent housing.

Abstract: There is disclosed a compression loaded torsional coupling device for use in drive shafts to provide a resilient interface between input and output portions of the shaft. Elastomeric cushions between fins extending in alternating fashion from opposed coupling members provide the resiliency. The coupling is produced by a unique process. Elastomer is first inserted into alternating gaps between adjacent fins. This elastomer is then compressed by applying a torque to rotate the coupling members with respect to each other. Elastomer is then placed in the remaining gaps. The torque is then released, permitting the compressive forces to redistribute in the elastomeric material around the circumference of the coupling.

Abstract: A thread bobbin holder device having improved sealing between shafts, and consequently less bearing wear. The bobbin holder device is constituted by a bobbin holder body with a bobbin fitted on the outer circumference thereof through a bobbin holder member. A piston controlling the amount of tension between the bobbin and the bobbin holder member is provided inside the bobbin holder body. A holder shaft and a second shaft are provided, both of which have a longitudinal throughhole formed therein. A support body rotatably supports the bobbin holder body. A shaft joint connects the holder shaft and the second shaft. A tubular elastic member is disposed in the shaft joint and is fitted into respective end portions of the holder shaft and the second shaft.

Abstract: A coupling for joining a pair of shafts which are rotatably supported without a common axis in such a manner as to accommodate misalignment and provide torsional flexibility includes hubs on the ends of the two shafts, each of the hubs having axially extending cams with opposed surfaces that create openings for insertion of deformable members. A spider-like coupling element formed of a rubber-like material has a central base and legs which extend from the base into the openings to contact the opposed cam surfaces. The legs of the coupling element are circular or elliptical in cross section so that they contact the opposed cam surfaces essentially at lines when there is no load on the coupling and the legs deform in unconstrained compression to increase their area of contact with the opposed cam surfaces as the load increases, creating a nonlinearity in the relationship between the stiffness of the coupling and the applied torque.

Abstract: A coupling device (30) for connecting the armature (16) of an electric motor (10) to a piston (26) of a pump assembly (20) comprises an input member (32) which rotates and imparts the rotation to an output member (34), with a resilient member (36) disposed between the input member (32) and output member (36) to prevent the transmission of noise-generating vibrations between the electric motor (10) and pump assembly (20). The input and output members (32, 34) have respective axially extending projections (44, 46) circumferentially spaced-apart from each other and fingers (52) of the resilient member (36) extend radially into spacings between the projections (44, 46) in order to transmit rotation of the input member (32) to the output member (34) without permitting transmission of noisegenerating vibrations therebetween.

Abstract: A coupling for connecting the end of the camshaft of an internal combustion engine to the drive shaft of an ignition distributor. The coupling comprises a drive coupling member that is fixed to the drive shaft of the ignition distributor. The coupling member has a pair of axially extending lugs that have surfaces that engage surfaces formed on a pair of lugs that extend axially from the end of the camshaft. A spring member is fixed to the coupling member which has a pair of curved spring portions that engage other surfaces on the camshaft lugs and which serve to prevent backlash between the shafts.

Abstract: A coupling device for coupling a loom shaft to the shaft of a weft selecting device in a weaving loom, the device comprising two opposed discs having mutually engaging teeth which automatically respond to reversal in direction of rotation of the loom shaft to introduce a desired phase shift between the loom shaft and the weft shaft, the coupling device having automatic means for locking the disc teeth after each reversal in direction of the loom to maintain the newly phase-shifted mutual orientation of the discs.

Abstract: A drive arrangement is disclosed which provides for the transfer of torque between two non-aligned shafts. The drive arrangement includes an intermediate shaft having outwardly projecting claws secured to each end thereof which are engageable in a positive driving manner with corresponding claws formed on the first and second shafts, respectively. A pair of resilient members are interposed between the claws at each end of the intermediate shaft which provide flexible couplings for facilitating the transfer of torque therebetween. Such a drive arrangement corrects for pure eccentricity between the parallel axes of the first and second shafts as well as correcting for any lack of parallelism between these axes.

Abstract: A rider roll structure is provided by a beam with at least a pair of rider rolls mounted thereon with adjacent ends of the rolls being mounted in a bearing assembly wherein shafts extending from each adjacent end of each roll are provided at their axial ends with a land and groove configuration so that the lands formed on one shaft are received in the grooves formed on the other and a resilient member is received within the grooves and is shaped so that it extends between mating land areas so that drive from one roll to the other is through the resilient member and the resilient member can accommodate slight angles between the axes of rotation of the rolls. A sleeve surrounds the shaft and the resilient member is keyed to this sleeve which in turn is mounted in a bearing that is mounted on the rider roll beam.

Abstract: An elastic shaft coupling of the disk type in which the inner member is connected to one shaft and is affixed to an annular elastic (rubber) member by vulcanization. The rubber member is provided with an array of formations interdigitating with complementary formations of the outer member which is connected to the other shaft. The rubber body is retained against the outer member by pure radial precompression between the inner and outer members and progressively decreases in cross section radially outwardly, i.e. with increasing diameter, to maintain the shear stress substantially constant within the rubber member.

Abstract: A coupling between two shafts, that can be readily disassembled therefrom, without disturbing the shafts, the coupling including two semi-circular members held clamped around each one of the shafts, each member having a singular, axially projecting, eccentrically located tooth, the four teeth intermeshing together, and also with a rubber shoe, that absorbs any momentum shock between the teeth.

Abstract: In an elastic coupling with two similar central gears assemblable on respective shaft ends and having rows of teeth, respectively, disposed adjacent one another, and a planet gear with a row of teeth having an angular pitch equal to that of the rows of teeth of the central gears, the central gears being turnable elastically resiliently so that the flanks of the teeth of the central gears form generally wedge-shaped virtual tooth gaps having a profile varying with reciprocal turning of the central gears, the teeth of the planet gear being also generally wedge-shaped and projecting into the generally wedge-shaped virtual tooth gaps, the tooth flanks of the teeth of the planet gear being in direct contacting engagement with the tooth flanks of the teeth of the central gears, and the teeth of the planet gear and the teeth of the central gears being spring-biased radially toward one another so that the teeth of the planet gear remain fully in engagement in the virtual tooth gaps.

Abstract: An overload clutch is described which includes a drive member and a driven member which are coaxial and have concentric cylindrical surfaces which form an annular chamber. One or more rollers of elastomeric material are positioned in the chamber with the rollers in rolling contact with the concentric cylindrical surfaces. Teeth project into the annular chamber from both surfaces and engage the rollers from diametrically opposite positions to transmit torque from the drive to the driven member. Excessive torque causes the rollers to compress between the two engaging teeth, the roller passing between the teeth and allowing the drive member to rotate relative to the driven member.
