Abstract:
The present invention is directed to a retention element for retaining first and second components in assembled relationship. The first component comprises a body having first and second external surfaces and an inner wall defining an aperture extending through the body, and the second component comprises a longitudinal member having a size and configuration to permit insertion within said aperture to thereby assemble the components. The retention element comprises: an elastromeric protuberance extending into the aperture from a base adhering to the inner wall to a distal edge which spans a portion of the aperture. The protuberance also has an inside wall and an outside wall which meet at the distal edge and together define a flexible free end. Upon insertion of the second component into the aperture of the first component, the free end of the protuberance flexes in the direction of insertion such that the force required to assemble the two components is less than the force required to disassemble the two components.
Abstract:
A tolerance ring has a band (16) with outwardly extending corrugated protrusions forming waves (2) which engage a surface (8) of the bore (4) in a housing (5). At one end of the tolerance ring is an outwardly flared guide surface (15) extending axially from the band (16). The guide surface (15) acts as an enlarged entrance to the band (16) for a shaft (3) to be mounted in the bore (4) by insertion into the tolerance ring. The use of the guide surface (15) assists assembly and reduces or eliminates particle production. It is also possible for the corrugated portions to extend inwardly, for the guide surface to be inwardly flared, and for the tolerance ring to be mounted on the shaft prior to insertion in the bore.
Abstract:
A component includes a first member, a second member and a device for fastening the first member to the second member. A first hole extends through a portion of the first member and a second hole extends through a portion of the second member. The first member and the second member are positioned such that the first hole and the second hole coincide. The fastening device includes an elongated fastening element arranged in the coinciding holes and a bushing arrangement arranged around the fastening element and adapted to establish a load transmission path between the first member and the second member. A first part of the bushing arrangement is arranged such that an inner surface thereof is positioned at a distance from an exterior surface of the fastening element for establishing a first load transmission path via the bushing arrangement and bypassing the fastening element in a first load condition. Further, the fastening device is adapted to allow the first member to move relative to the fastening element in a second load condition such that the first part of the bushing arrangement can be brought into contact with the fastening element for establishing a second load transmission path between the first member and the second member via the fastening element.
Abstract:
A hitch for connecting a movable object to a rigid rod which includes a semi-rigid main substrate including a plurality of grooves, a flexible element fixedly formed over the main substrate including a first portion for gripping a rigid rod, a clamp connected to the first portion of the flexible element. The clamp includes a lever that couples the clamp to at least one of the plurality of grooves of the main substrate such that the first portion can grip the rigid rod.
Abstract:
A conduit arrangement for a pressurized fluid, in particular for connecting a gearbox to an oil cooler. The conduit arrangement comprises a first fluid conduit and a second fluid conduit which can be connected to a housing, such as a gearbox housing, by means of a connecting arrangement. The connecting arrangement has a first connecting part and a second connecting part which have a respective through-passage. At least one of the connecting parts is made of plastic, wherein at least one of the fluid conduits is made of plastic. The plastic connecting part and the plastic fluid conduit are integrally connected to one another.
Abstract:
The sealing connector ensures sealing between a gas cartridge having an outlet fitting and a transmission member for filling a combustion chamber of a gas fastening device having an inlet fitting with gas and includes two internal sealing sleeves for receiving the two fittings, at least one of which is made of flexible material, with, at the bottom of this sleeve, a flexible transverse annular partition for dimensional adjustment, and an external slide. A rigid transverse annular partition is provided at the bottom of the other of the two sleeves to serve as a support for a fitting.
Abstract:
A coupling device with a housing (12) and a locking element (11, 11′) for receiving a cylindrical connecting element (18, 18a), whereby an operating element (30) for the releasing of the locking element is accessible by way of an opening in the housing (12, 12′) and whereby the locking element (11, 11′) includes at least one holding portion (26), whereby the locking element (11, 11′) includes a first spring arm (20) with a holding portion (26) which arm extends from the operating element (30) all the way to a wall of the housing (12, 12′) opposite the operating element, whereby the spring arm (20) is constructed at the opposite wall with a joint portion (24). Alternatively, there are two spring arms with joint ends that engage each other.
Abstract:
An electric motor includes a stator, a housing supporting the stator and having a bearing seat with an inner surface and an inner end, a bearing having an outer surface, a shaft rotatably supported by the bearing, and a rotor supported by the shaft. The motor also includes a tolerance ring having an interior surface, an exterior surface disposed against the bearing seat inner surface, and a plurality of elastic corrugations. Each of the elastic corrugations projects radially from the interior surface, defining a shoulder section disposed between the bearing and the inner end of the bearing seat. The shoulder section generates a spring force against the bearing to axially and radially support the bearing and to axially preload the bearing.
Abstract:
A flexible drive shaft extension for hand tools comprises serially nested, socket-ended Shaft components of polygonal cross-section which have freedom of universal motion from axial alignment limited to about five degrees of arc and which are forcibly retained in coupled connection within a sleeve by spring biasing.
Abstract:
Two structural components having a rotational symmetry relative to a central longitudinal axis, are releasably connected to each other by a clamping mechanism which engages two interface rings secured to the respective structural component. The clamping mechanism is formed by tensioning elements (5) held together by at least one, preferably two straps (1, 2). A lock (15) with two hinged tensioning levers holds the strap or straps releasably together. For this purpose each strap end is journalled by a journal bolt to the tensioning lever (18, 19). Locking elements (25, 26, 28, 30) hold the tensioning lever (18, 19) in a locked position in the lock. An electromagnetic drive or the like unlocks the tension levers for releasing the tensioning strap or straps, whereby the opening motion of the tensioning levers is retarded or delayed by one or more springs in a controlled manner to avoid or at least optimally reduce the triggering of harmful vibrations and the introduction of undesirable loads in the components being released.
