合している。In order to reduce the weight and strength of the connecting rod, the applicant of the present invention has proposed a connecting rod that connects the big end and the 7-run part of the cap with a U-shaped fastening fitting instead of drilling bolt holes in the 7-run part of the cap. are doing. 1st
, 2 shows this type of connecting rod. In the figure
1 is a rod body, and one end thereof has a small end 2vl-i connected to a piston pin 3. 4 is a big end, 5 is a cap that is combined with this big end 4 and connected to the crank 1lII6, and 7 is a U-shaped holding flange l (; 8, 9'ii) of each big end 4 and cap 5. , lO is the lf of the fastener 7.
! A press bolt 11 is screwed in, and 11 is a presser piece overlapped on the flange surface of the cap 5. The presser bolt 10 is pressed against this presser piece 11 to connect the big end 4 and the collar f5.
このように構成したコネクチングロッドは、ピストンの

０回転の高速往復運動を斐はクランク軸６を回転させる
ため、ロッド本体１のピストン３側には往復運動の慣性
力が、ビックエンド４側には回転による慣性力を受ける
と共に、この慣性力は締結金具７を伝達してキャップ５
に伝わる。上記慣性力は高速回転のため非常に大きく、
ビックエンド４とキャップ５と全充分な力で締付けてい

じて重大な事故を誘発することになる。The connecting rod configured in this way receives the explosive force of the piston, and the piston moves at a rate of 10 (1 (1 to 500) per minute).
Since the high-speed reciprocating motion of 0 rotations rotates the crankshaft 6, the piston 3 side of the rod body 1 receives the inertia force of the reciprocating motion, and the big end 4 side receives the inertia force due to the rotation, and this inertial force transfers the fastening fitting 7 to the cap 5
It is transmitted to The above inertial force is very large due to high speed rotation.
If the big end 4 and the cap 5 are not tightened with sufficient force, local stress may cause damage to the big end or the cap, or damage due to misalignment between the big end and the cap, leading to a serious accident.
