Abstract
Official abstract text for this publication.
In order to reduce bending vibration of a connecting rod, a dynamic absorber ( 50 ) configured to reduce the bending vibration of the connecting rod ( 10 ) is provided on a piston ( 1 ).
First claim
Opening claim text (preview).
1 . A reciprocal rotation mechanism of an engine including a piston configured to reciprocate in a cylinder, and a connecting rod configured to connect between the piston and a crank shaft, in which the connecting rod includes a large end portion formed with a shaft insertion hole into which the crank shaft is inserted, a small end portion formed with a pin insertion hole into which a piston pin for connection of the piston is inserted, and a connecting portion configured to connect both of the large end portion and the small end portion, the reciprocal rotation mechanism comprising: a dynamic absorber provided on the piston or the connecting rod to reduce bending vibration of the connecting rod. 2 . The reciprocal rotation mechanism of claim 1 , wherein a boss portion formed with a pin support hole at which the piston pin is supported is formed at each end portion of the piston in a center axis direction of the piston pin, and the dynamic absorber is provided on an outer surface of each boss portion in the center axis direction of the piston pin. 3 . The reciprocal rotation mechanism of claim 1 , wherein the dynamic absorber is provided on a side surface of the connecting portion in a thickness direction of the connecting rod. 4 . The reciprocal rotation mechanism of claim 1 , wherein the dynamic absorber is provided on a side surface of the connecting portion in a transverse direction of the connecting rod. 5 . The reciprocal rotation mechanism of claim 2 , wherein the dynamic absorber is provided on a side surface of the connecting portion in a transverse direction of the connecting rod. 6 . The reciprocal rotation mechanism of claim 3 , wherein the dynamic absorber is provided on a side surface of the connecting portion in a transverse direction of the connecting rod.
