Abstract: A torsion damper comprising juxtaposed resilient plates which operate in parallel and are interposed between a support member and a hub. Each resilient plate comprises at least one resiliently deformable arm. The torsion damper has at least two pairs of similar resilient plates. One of the pairs lies between the plates of the other pair and is offset with respect to the other pair by an angle such that the two pairs of plates are radially balanced. The resilient arms of any one pair are aligned with each other.

Abstract: A housing having a spindle mount for mounting a spindle supporting magnetic disks for a magnetic data storage disk system. A bearing cap having seals is mounted on the exterior of the housing. A spindle clamp having a male bayonet mount is inserted through the bearing cap and engages a mounting cup having a female bayonet mount. A belleville washer is mounted onto the clamp between the bearing cap and the head portion of the clamp. The clamp and cup are designed so that the washer is compressed as the bayonet mount engages. This exerts a constant uniform pressure on the bearing cup as well as restraining the bayonet mounting from disengaging. The bearing cap is held tightly against the exterior of the housing as well to seal the bearing and the inner housing from the exterior environment.

Abstract: A coupler interconnecting a wheel speed transducer with a rotating wheel of an aircraft. A cylindrical housing has a pair of orthogonal passages extending therethrough. One of such passages communicates with a slot within one end of the housing, the slot being adapted to slidingly receive a blade from a drive cap of the wheel. The other of the passages slidingly receives a member having a hub extending therefrom for engagement with the rotatable shaft of the wheel speed transducer. Various types of possible misalignment are accommodated and corrected by the capability of the blade to slide within the slot and of the member to slide within its passage. The coupler substantially eliminates backlash and accommodates high temperature operation.

Abstract: A method and apparatus for tensioning a strap loop around an object and terminating the tensioning of the strap loop at a predetermined loop tension. The object is encircled with a loop of strapping having a predetermined thickness, width, and coefficient of friction. A leading end portion of the strap is restrained while disposing a trailing end portion of the strap adjacent a traction wheel that is rotatable about a first axis at a predetermined maximum available torque. A pressing member that is pivotable about a second axis oriented parallel to the first axis and that has a predetermined configuration and coefficient of friction is biased toward the traction wheel so as to press the strap trailing end portion against the traction wheel.

Abstract: That flywheel of a torsional vibration damping apparatus which is connected to the crankshaft of an internal combustion engine in a motor vehicle has a concentric annular lubricant-containing compartment for a relatively small number of elongated arcuate coil springs which bear against the teeth of a flange secured to a second flywheel which is coaxial with the first wheel and carries a friction clutch. The latter can be engaged to transmit torque from the second flywheel to the input element of a variable-speed transmission in the power train of the motor vehicle. The compartment of the first flywheel is lined by resilient shells which are installed in stressed condition and at least substantially surround the coil springs. The shells have integral abutments for the end portions of the springs, or the abutments are fixed to or alternate with arcuate portions of the shells.

The portions may be integral with or attached to the reel body. Further, the distance between the longitudinal axis of the fishing reel and each of the tops of the attaching portions, is longer in length than the distance between the longitudinal axis of the fishing reel and the periphery of a spool flange.

Abstract: A coupling mechanism for coupling two elements in a manner providing for transfer of the rotation moment of one element to the other element. The mechanism comprises at least two coupling element (11, 12), each coupling element having a pair of radially outwardly directed spherical pivot portions (11', 12'). The spherical pivot portions of the coupling elements are housed in an intermediate element (8) comprising a continuous inner ring member (10) defining spherical pockets for the pivot portions and an outer ring (9) circumscribing the inner ring. The pivot portions (11', 12') are rotatable at least around their cardioids while being contained in pockets formed in the inner ring of the annular intermediate element (8), such that the one coupling element can swivel in one plane and the other coupling element can swivel in a plane perpendicular to the first relative to the intermediate element (8).

Abstract: Multiconvoluted boot seal for universal joints and other mechanisms in which convolution side walls have radial ribs formed therein to strengthen the walls to reduce wrinkling and resultant cracking at high joint angles. The ribs on one side wall are external at high joint angles and mesh with rib spaces formed by internal ribs on an adjacent side wall. This meshing reduces relative turning movement between the side walls so that abrasion and boot seal wear is reduced.

Abstract: A universal joint (310) includes a substantially hemispherical cup-shaped yoke (311) in which is disposed a cross trunnion (312) and which is disposed in a ring (315). Pins (321, 322) connect the ring to the cross trunnion and to the yoke. Lubricant in an annular channel (319) in the ring provides lubrication for the pins (321, 322), whose ends disposed in the ring (315) are surrounded by needle bearings (31). A first shaft (340) is integrally connected to the cross trunnion (312), and a second shaft (513) is integrally connected to the yoke (311). By joining the yokes (311) of two such joints (310) which a common shaft (313), a composite joint (300) can be formed.

Abstract: Torsion damping isolator assemblies (19 or 100 or 200) are disposed for damping torsionals in a vehicle driveline. The assemblies include spiral springs (62 or 202, 204) and a vane damper assembly (22 or 206) disposed in parallel and immersed in automatic transmission fluid of a torque converter housing (24). Damper assemblies (22 or 206) include first and second relatively rotatable housing members (66, 68 or 208, 210). Housing members (66 or 208) are connected to radially inner ends (62b or 202b, 204b) of the springs, and members (68 or 210) are connected to radially outer ends (62a or 202a, 204a) of the springs. The housing members define chambers which vary inversely in volume in response to flexing of the spring assemblies by driveline torsionals. The chambers communication with the fluid in the torque converter housing via restricted passages (86, 88 or 220f, 220g). As the chambers vary in volume, energy from the torsionals is converted to fluid pressure in the chambers decreasing in volume.

Abstract: The universal joint arrangement includes a first adapter having two projecting support formations; a drive plate having a first pair of matching depressions or pockets is seated with these depressions on the projecting support formations of the first adapter and the drive plate has a second pair of pockets for the projecting support formations of a respective second adapter.

Abstract: An elastomer boot and sleeve combination for sealing a blow-molded boot to a cylindrical member, such as a shaft, includes an intermediate sleeve which is received between the neck of the boot and the shaft. The sleeve is split and is formed with a pair of forks at one end and a tongue which is received between the forks at the other end. The tongue and forks are formed with inclined surfaces along their mating walls such that the tongue is captured between the forks when the sleeve, which is molded in a semi-open position, is closed about the shaft. The neck of the boot is formed with protuberances which engage the walls of outwardly-opening recesses in the forks so that when the neck is clamped down on the sleeve a force is created which urges the forks together toward each other and against the tongue, thereby forming an effective clamp which seals the neck of the convoluted boot to the shaft.

Abstract: An apparatus which transmits torque between two flywheels mounted between the crankshaft of the internal combustion engine and the input shaft of the change-speed transmission in a motor vehicle has a composite damper system having first and second dampers which operate in series and a friction generating device which is operated with a delay following each change of the direction of angular movement of one of the flywheels relative to the other flywheel. The input element of one of the first and second dampers is the output element of the other of the first and second dampers.

Abstract: A fluid transfer structure for a transmission has a tube disposed in a central bore of a shaft. The shaft and the tube cooperate to provide a feed passage, central of the tube, and a substantially annular lube passage formed between the tube and the central bore. The tube and shaft have cooperating structures that provide proper alignment of the tube in the central bore. A plurality of radial passages are formed in the shaft in communication with the central bore. At least one of the radial passages is in communication with the feed passage which is sealed from fluid communication with the annular lube passage. The remaining radial passages are in limited fluid communication with the annular lube passage. The tube has radially outwardly extending portions aligned with respective ones of the radial passages and cooperate therewith to form flow restriction structures. The extending portions are not fully annular such that free fluid flow is possible along the length of the annular passage.

Abstract: A resilient shaft coupling, especially for Diesel engine drives, essentially comprises two rigid coupling parts such as a hub on the drive side of the shaft coupling and a flange ring on the end of the drive shaft opposite to the drive side, whereby the hub and the flange ring are connected in an elastic rotating manner via a series of identical elastic annular connecting links. Radial supports for the elastic annular connecting links are provided at one of the rigid coupling parts in order to avoid improperly restraint masses that cause imbalance of the shaft due to centrifugal forces. In order to improve the angular movability of the resilient shaft coupling, the radial supports are provided with angular movability. This is achieved by a metallic ring membrane which provides angular movability between two axially neighboring annular connecting links, whereby the ring membrane is clamped between the connecting rims of the annular connecting links.

A thin can-shaped shell is mounted over the inner rotor and an outer frame is mounted over the shell. The outer frame includes an outer rotor carrying magnets adapted to couple magnetically with the inner rotor to drive the pump through the shell. A pair of guide posts are anchored to the casing and extend through holes in the outer frame for guiding the outer frame into and from an assembled position. Bolts are threaded into the guide posts and have suitable abutments for engaging and moving the outer frame between assembled and disassembled positions.

Abstract: A one piece, mechanical, flexible coupling for interconnecting driving and driven shafts, which is capable of accommodating separate or combined angular, skewed or parallel shaft misalignments and axial shaft movements while permitting limited torsional or radial deflection thereof. The coupling is fashioned from a single piece of metal or other rigid material and includes a plurality of parallel, axially spaced, annular discs lying normal to the coupling's longitudinal axis and integrally interjoined with one another and with two shaft connector hubs by intervening spacers. The discs and hubs operate as flexible, zero back lash coupling portions at opposite ends of an integrally intervening midsection which operatively permits limited radial or torsional shaft deflection and is made up of a selected number of elongated flexible vane elements lying parallel to and radially displaced from the central longitudinal axis of the coupling.
