    摘要: A crankshaft for combustion engines has a number of components joined to each other. Each component comprises a counterweight, a portion of a main bearing journal, and a portion of a crank bearing journal. Adjacent components are so arranged that their crank bearing journal portions are connected to each other to form a complete crank bearing journal, and their main bearing journal portions are secured to each other to form a complete main bearing journal. One of each pair of portions is longer than the other; and oil ducts extend through cavities in the components but do not communicate with those cavities. Instead, the ends of the ducts open through the journal bearing surfaces, and specifically through the longer of the two journal portions so that the opening of the ducts can be central of the journal and still not interfere with the joint between the components.

    摘要: A bearing arrangement for a connecting rod big end journalled on a crankshaft pin, for lubrication by splash or mist. Adjoining the cylindrical journal on the crankshaft pin and the rod big end, facing generally planar surfaces on the crankshaft and the rod big end have a pattern of shallow lubricant pumping grooves to provide a constant, reliable flow of oil through the bearing. At the opposite end of the connecting rod plain bearing, other plane surfaces may provide either draining grooves or grooves which pump oil outward to an axial bearing surface.

    摘要: A crankshaft which is composed of a plurality of individual elements. Each of said elements comprises a crankshaft section with an end face and bearing surface means and also comprises a main shaft journal section with an end face and with bearing surface means. The end faces of pin sections to be connected to each other are electron beam welded together after centering pins have been inserted in bores arranged in, and perpendicular to the end faces to be welded together.

    摘要: An annular bearing carried by a journal box in circumferentially embracing relation about a journal of a shaft is sized so as to provide a predetermined clearance between it and such journal to permit relatively free rotation of the shaft therewithin. A lubrication system includes lubricating fluid contained within a sealed annular chamber disposed in communication with the clearance so as to direct a flow of such fluid axially through the clearance for lubrication of the bearing and journal. The chamber is cooperatively formed between a radially extending shoulder provided on the shaft at one end of the journal in juxtaposed relation to the journal box and an adjacent end of the bearing.

    摘要: A single-cylinder internal combustion engine comprising a crankshaft running on tapered-roller bearings in the front walls of the crankcase and a vane-type oil pump for the supply of oil to the connecting-rod bearing at the crankpin of the crankshaft, consisting of a rotatively driven ring with a front-end annular groove whose depth diminishes to zero from a point of maximum depth as far as an opposite peripheral point and wherein an elastic pin engages dividing the space defined by the annular groove and an adjacent stationary abutment into a suction chamber impinged upon by oil and a delivery chamber, the latter communicating via an oil drainage hole and oil ducts in the crankshaft with a crossbore of the crankpin ending in the connecting-rod bearing.
