  • Patent number: 7089903
    Abstract: In an internal combustion engine including a valve actuating mechanism, a vibration control member made of vibration control alloy is interposed in a path of vibration transmission between a camshaft and a cylinder head. The vibration control alloy has a vibration isolation capability comparable to that of rubber, but provides a durability and a resistance to degradation comparable to those of metal and alloy that are typically used in internal combustion engines. Therefore, a desired vibration control can be achieved while ensuring a required reliability, durability and resistance to degradation. The present invention is particularly useful when the valve actuating mechanism is provided with a variable lift, variable timing or variable compression mechanism because such a variable mechanism increases the stress to the engine, and tends to cause more vibrations than a more conventional non-variable valve actuating mechanism.

  • Patent number: 5775817
    Abstract: The present invention is directed to a split bearing assembly and the method of manufacturing the same which substantially reduces material yielding and deformation during fracture. The bearing assembly includes a saddle-like main body with first and second legs and a removable saddle-like bearing cap with first and second legs. The ends of the cap are secured in end-to-end engagement with mating ends of the first and second legs of the body to define a journal receiving opening. The mating ends are defined by a portion of rough uneven mating surfaces formed by fracturing the cap from the body and a slot or saw-cut portion which operates to reduce the cross-sectional area of the first portion. The reduction in cross section of the mating ends, through the use of the saw-cut, operates to minimize the magnitude of the force which is required to initiate the fracture of the bearing cap from the body of the bearing assembly thereby limiting the deformation of the material in the fracture area.

  • Patent number: 5733049
    Abstract: A assembly of mated molded parts and a method for making same are disclosed in which the assembly has first and second parts with precisely mating surfaces. The first part is formed by molding, casting, or the like such that the mating surface of the first part is formed with at least one protrusion. The second part is formed in place against the first part such precisely mating surfaces are formed with the second part enveloping the protrusion. The two parts thus formed are forced apart from each other. The protrusion may be formed with a head which interlocks with the second part. When the parts are separated, the head breaks from the protrusion. In a particular embodiment, a bearing cap is disclosed having a central opening for the passage of a shaft.

  • Patent number: 5716145
    Abstract: For a process for fracture separating the bearing cover of a multi-part bearing arrangement, particularly in crankcases of internal-combustion engines, by means of a half-mandrel in a bearing bore partially bounded by the bearing cover, for separating integrally constructed fastening flanges of the bearing cover from the remaining part of the bearing arrangement, it is suggested for producing fracture separating surfaces in planes sloping with respect to one another that the pairs of corresponding fracture separating surfaces of the bearing cover and the remaining part of the bearing arrangement are produced in separating areas which together enclose an obtuse angle (.alpha.) having a case-side vertex by at least one half-mandrel whose curvature radius, as a function of the respective obtuse angle (.alpha.), is selected to be by 0.5% to 5% smaller than the constant radius of the bore receiving the half-mandrel.

  • Patent number: 5709482
    Abstract: A hangar bearing is designed to be employed in a drying oven, generally known as a "tunnel" type, which is used to dry plywood, veneer board, fiber, or gypsum board. The hanger bearing main body support is made from a pair of identical stamped forms or fabricated plates which include various matched bores to facilitate both mounting and mutual securement. Each of the main body plates includes a depression that conforms to provide a bearing insert support cavity when the plates are fitted together. The bearing insert support cavity may or may not include anti-rotational flanges and/or longitudinal travel stops to hold the semi-cylindrical bearing insert element in place. A steel retaining loop or strap is provided to overarch the bearing element, once it is in place, the loop or strap being preferably provided with a hinge and a releasable retaining clip.

  • Patent number: 5709481
    Abstract: A roll-feed apparatus which is removably attached to a printer/plotter that has a self-alignment feature. Media, such as paper, vellum or film is pulled through the printer/plotter. However, a back-tension is created in the roll-feed apparatus by creating a pre-determined force on the shaft to which a roll of media is mounted. By increasing the force on the shaft, frictional drag is induced impeding the shaft's rotation. It has been found that the rotational impedance, in conjunction with the pull of the printer/plotter, corrects any misalignment of the media in approximately six meters of media run.

  • Patent number: 5669717
    Abstract: A hydrodynamic sleeve bearing for supporting the shaft of a relatively large electromechanical machine. The bearing includes a base element and a cap element matable about the shaft to produce the bearing housing. The bearing housing when assembled includes a shaft receiving portion through which the shaft extends and a sump portion for containing a lubricant fluid. The design of the present invention minimizes the axial length of the shaft receiving portion to approximately that of the bearing liner contained therein. As a result, the weight of the cap element will be significantly reduced over many prior art constructions. Respective lubricant seals are attached at opposite end faces of the shaft receiving portion. The lubricant seals and the end faces are configured to permit lubricant fluid to flow directly back into the sump. The lubricant seals may be installed in a plurality of angular orientations, which may be particularly useful if a selected sensor device is installed thereon.

    Abstract: A main bearing structure for an internal combustion engine includes a cylinder block with main bearing bulkheads which are bored for receiving cylindrical alignment elements carried in a main bearing cap assembly. The cylindrical alignment elements and the bores formed in the cylinder block are not concentric, with the result that a majority of the cylindrical alignment elements extending into the cylinder block are in interference fit with the cylinder block itself.

  • Patent number: 5501529
    Abstract: A bearing insert for being cast into an aluminum alloy engine block is made by a ferrous powder metal sintering process to make a skeleton structure which is permeable to the molten aluminum alloy in the block casting process. The insert is made of a material having a similar composition as the bearing cap so as to equalize machining and thermal expansion properties of the cap and block so as to provide improved roundness of the bearing in the machining operations for forming the bearing support and in operation of the engine.

  • Patent number: 5325826
    Abstract: A mechanism for providing a continuous supply of oil on camshaft lobes used in an overhead cam internal combustion engine. The mechanism includes camshaft bearing caps affixed to the engine about the camshaft journals. Protruding from the side surface of the central portion of the bearing caps are oil diverter pads. The oil diverter pads cause oil that builds up on the surface of the camshaft journals to be diverted toward the camshaft lobes to provide lubrication between the camshaft lobes and the roller finger followers.
