Abstract

PURPOSE:To reduce vibration and a horse power loss, by a method wherein the center of gravity of a crank is kept at the proper center of gravity of a crank in response to the number of revolutions. CONSTITUTION:A cylinder 5 is formed in a crank 1. A weight 2 and a spring 3 are placed therein, and the weight 2 is moved according to the number of revolutions by means of a passage 4 through which an oil pressure proportional to the number of revolutions is fed from a crank shaft 6. This causes the center of gravity of the crank to be kept at the proper center of gravity of the crank in response to the number of revolutions.

Description

【発明の詳細な説明】 この発明は、クランクの重心を回転数に応して適したも
のとするクランクの重心移動装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a crank center of gravity moving device that makes the center of gravity of the crank suitable according to the rotational speed.

があった。Conventionally, it was not possible to change the weight of the prime mover's crank depending on the rotation speed. Therefore, in an inappropriate rotation range, the center of gravity of the crank changes due to differences in inertial energy, etc., resulting in vibrations and a consequent loss of horsepower.

のである。The present invention was invented to eliminate these drawbacks, and to explain it with reference to the drawings, the method shown in FIG.
A cylinder 5 is made inside the crank 1, a weight 2 and a spring 3 are placed inside it, and the weight 2 is moved according to the rotation speed by a passage 4 through which IC hydraulic pressure flows from the crankshaft 6 according to the rotation speed. Bring the center of gravity of the crank to the appropriate center of gravity for the rotation speed. In the case of Fig. 2, the weight 1:3 is attached to the crankshaft 11 so that it can rotate, and the cover acts like a gyro. Bin 8 has the weight 12 attached to the crank 10, and Bin 9 has the weight 12 attached to the crank 10. The centrifugal force is controlled by a spring 7 according to the number of rotations, and the center of gravity of the crank is brought to the appropriate center of gravity for the number of rotations.
