The research and analysis included an example crankshaft of a medium-speed rotation main engine of the ship Buckau Wolf R8 DV-136. The crankshaft was 3630 mm long, with a mass of 9280 N, ten 149 mm main journals, and eight 144 mm crankpins. Figure 2 shows the crankshaft of the Buckau Wolf R8 DV-136 engine with the main journals numbered.

In path-controlled grinding, unlike the cylindrical plunge grinding, the contour of the pin journal is achieved with the coupling actions both of the eccentric rotation of the pin and the grinding wheel linear movement. Since the circumferential feed rate varies periodically in path controlled grinding of crankshaft pin, the tangential and normal grinding force keep unsteady during the whole ...

Re: Grinding sides of crankshaft counterweights. I think the best way to spend time on a crank is to just fill in the moon craters on the counterweights and shave them smooth on the lathe to reduce windage. That, and bullnosing the front and rear of the crank and hitting it with a roloc sanding disk just to smooth the grinder marks out of it.

Crankshaft The crankshaft is the part of all main engines that is converting the reciprocating piston movement to rotational motion. In order to do the conversion between two motions, the crankshaft is equipped with crankpins, as additional bearing surfaces whose axis is offset from that of the crank, to which the "big ends" of the connecting rods from each cylinder attach.
