Instead, it is a continuous rod whose side width gradually increases from the small end to the large end.

Figures 4 and 5 show the a-a section and the b-b section, respectively, of the proposed rod section in which the front width of most of the connecting rod sections is narrower than the minimum width of the small end neck of the conventional rod section. The cross-sectional views, FIGS. 6 and 7, show parts a-a and b-b, respectively, of the rod part according to the present invention whose small end neck is the same as the front width and side width of the small end neck of the conventional connecting rod. FIG.

Claims

[Scope of utility model registration request]

Continuous pistons for crankshaft eccentric engines, etc.
Pin bearing (small end) and crank pin bearing (
In the rod portion between the large end (large end), the minimum width in front of the connecting rod where the bearing hole is open is approximately 26% between the center of the piston pin bearing and the center of the bearings at both ends, For ordinary engines, the width would gradually increase from there towards the big end, but instead, the width is kept at the minimum width from the center of the piston pin bearing to about 65% between the centers of the bearings at both ends, and instead of For normal engines, the width of the side surface would be the same over almost the entire length, but from the center of the piston pin bearing to the center of the bearings at both ends, from about 26% to about 65%. The engine rod gradually expands to around 1.3 to 1.4 times the width, and from there the width is approximately the same until the large end, and the most part of the rod is made narrowest without reducing strength.
