タル部を傷つける惧れがあつた。 In the conventional crankshaft lubricating oil passage device, as shown in FIG.
The oil supply passage 04 is drilled diagonally toward the journal part 02 from the 1 side, and the oil supply passage 04 is made to communicate directly with the distribution oil passage 05 bored in the crank pin part 01, so that oil is forcibly filled from the oil supply passage 013. Lubricating oil is directly supplied from the oil supply path 04 to the outer periphery of the crank pin portion 01 via the distribution oil path 05. As a result, there was a risk that dirt and the like in the lubricating oil would enter the pin portion 01 and damage the metal portion of the pin portion 01.

The purpose of this product is to provide a crankshaft lubricating oil path device that prevents dirt, etc. in the lubricating oil from entering the pin and damaging the metal part when lubricating oil is supplied to the crank pin. As a means, a lubricating oil storage chamber for storing lubricating oil is formed in the crank pin portion of the lubricating oil path device, and an oil supply path bored in the journal portion is communicated with the lubricating oil storage chamber. The oil supply passage is characterized in that the oil supply passage does not intersect with the extension path of the oil supply passage and is biased towards the rotational axis side of the journal part, and the oil supply passage is communicated with the outer peripheral part of the crank pin part.

る。 A dead-end cylindrical lubricating oil storage chamber 10 is formed from one side of the crank pin portion 1, and its open end is sealed with a cap 11. On the other hand, an oil supply passage 4 is bored obliquely from the outer peripheral surface of the journal part 2 toward the crank pin part 1.
An inner end thereof is communicated with the lubricating oil storage chamber 10. An oil supply passage 5 is provided in the lubricating oil storage chamber 10 so as not to intersect with an extension of the oil supply passage 4 and to be biased toward the rotation axis LL side of the journal portion 2. It communicates with the outer peripheral part of the pin part 1. Further, a communicating oil passage 12 is bored in the journal portion 2 from its outer periphery to a part of the oil supply passage 4.

１の軸受６を潤滑する。 Next, to explain the operation of the embodiment of the present invention, pressurized lubricating oil from a lubricating oil pump (not shown) passes through the oil feed path 13 as shown by the arrow in FIG. After being stored in the lubricating oil storage chamber 10 through the oil supply path 4 and the communication oil path 12, the lubricating oil passes through the distribution oil path 5 from there and lubricates the bearing 6 of the crank pin portion 1.

滑油が分配油路５に直接流入することはない。 By the way, the distribution oil passage 5 is opened so as to be biased toward the rotation axis LL side of the journal portion 2, and when the crankshaft C rotates, the centrifugal force of the crankshaft C rotates the dirt in the lubricating oil to the opening of the distribution oil passage 5. Since the dirt and the like are pressed against the side surface of the storage chamber 10 that is substantially opposite to the storage chamber 10 (in FIG. Furthermore, the distribution oil path 5 does not intersect with the extension path of the oil supply path 4,
Since the lubricating oil supplied from the oil supply path 4 does not directly flow into the distribution oil path 5.

することができる。 As described above, according to the present invention, the lubricating oil storage chamber 10 for storing lubricating oil is formed in the crank pin portion 1 of the lubricating oil path device, and the lubricating oil storage chamber 10
The oil supply passage 4 bored in the journal part 2 is communicated with the oil supply passage 4, and the oil supply passage 5 is arranged so as not to intersect with an extension of the oil supply passage 4 and to be biased toward the rotation axis LL side of the journal part 2. , and this oil supply path 5 is communicated with the outer circumference of the crank pin portion 1, so that when the crankshaft C rotates, dirt, etc. in the lubricating oil will face the opening of the distribution oil path 5 due to centrifugal force. The lubricating oil is pressed against the side surface of the lubricating oil storage chamber 10, and since the distribution oil passage 5 is opened without intersecting the extension of the oil supply passage 4, the lubricating oil directly flows from the oil supply passage 4 into the distribution oil passage 5. As a result, the dust and the like can be separated more effectively, and the dust and the like will not enter the crank pin portion 1 and damage the metal portion, thereby extending the service life of the bearing. be able to.
