Abstract

1,095,371. Crank-shafts. GOTAVERKEN A.B. Feb. 9, 1966 [Feb. 17, 1965], No. 5643/66. Heading F2U. [Also in Division F1] In a marine Diesel engine crank-shaft built up from individually cast or forged cranks, each crank 3 is formed with five plane mounting surfaces 7, 9 and 11 to which a counterweight 5 may be bolted in a number of different positions relative to the crank 3, one of the mounting surfaces 7 being perpendicular to the central plane containing the crank-pin 4 and journal 2 of the crank-shaft and two of the surfaces 9 being parallel to said plane, the remaining surfaces 11 being located at an angle between the surfaces 7 and 9. The surfaces 7, 9 and 11 are tangential to an arc struck from the crank-shaft journal centre, each pair of surfaces having an included angle of 135 degrees. Where the counterweight encompasses more than two adjacent mounting surfaces, only the most spaced-apart surfaces of the balance weight fit and are bolted to the corresponding surfaces of the crank-web. The mounting surfaces may additionally be used for mounting a valve or fuel pump cam (15), Fig. 1 (not shown).
