A connecting rod 1 with small end 2 and big end 3 connected by shank 4. The small end can be rotatably connected to a piston and the big end to a crankshaft. The big end has a split-end configuration, with end cap 6 linked to main body 5. Threaded through bores (7, Fig. 4) are present on both sides of the end cap and are aligned with threaded through bores (8, Fig 4) in the main body of the big end. The end cap is screwed to the main body of the big end via screws (9, Fig.4). The big end main body is provided with recesses 10 so as to relieve stress on the last thread in bores (8, Fig. 4), The longitudinal axes of the recesses are parallel and offset with respect to those of the threaded bores. The recesses may have a semicircular or parabolic contour. |
