Filed: 1993-11-18
Abstract: PURPOSE:To improve lubricating ability of main journal parts by forming hollow parts inside the main journals connecting to two crank arms extending while having mutual phase difference of specified angles, and arranging the hollow parts on decided positions. CONSTITUTION:In a crankshaft 1, two crank arms 3 extended from both ends of #2, #4 main journals 4 mutually have phase difference of 180 degrees, the #2, #4 main journals 4 are apt to cause deformation tilting against the rotary axis when it is rotated at high speed, and bearing clearances are apt to be not uniform.
