Description
【０００１】0001
本考案は内燃機関用動弁装置に関する。 The present invention relates to a valve train for an internal combustion engine.
【０００２】0002
従来形のロッカアーム６及びロッカシャフト５を図２に示す。従来形のロッカ アーム６には溝７があり、ロッカシャフト５とバルブ回りへの給油孔は常時連通 し、一定の油が常に供給されていた。 A conventional rocker arm 6 and rocker shaft 5 are shown in FIG. conventional locker The arm 6 has a groove 7, and the rocker shaft 5 and oil supply hole around the valve are always in communication. However, there was always a constant supply of oil.
【０００３】0003
ところが、前記従来装置ではロッカ溝７が設けられているため、ロッカ軸受部 の軸受面積が少くなると共に、ロッカシャフトと軸受部の給油孔が常時連通して いるため軸受部への給油圧力が低くなり、潤滑油が十分に軸受部へ行きにくい欠 点があった。 However, in the conventional device, since the rocker groove 7 is provided, the rocker bearing portion The bearing area of the rocker shaft is reduced, and the oil supply hole of the rocker shaft and the bearing part are always in communication. As a result, the lubricant pressure to the bearing is low, making it difficult for lubricating oil to reach the bearing. There was a point.
【０００４】 本考案の目的は前記従来装置の問題点を解消し、ロッカアームの軸受面積を多 くすると共に、ロッカからバルブ回りへの給油を間欠的として、ロッカ軸受への 給油量を増加させた内燃機関用動弁装置を提供するにある。0004 The purpose of this invention is to solve the problems of the conventional device and increase the bearing area of the rocker arm. At the same time, oil is supplied to the rocker bearing intermittently from the rocker to the area around the valve. An object of the present invention is to provide a valve train for an internal combustion engine that increases the amount of oil supplied.
【０００５】[0005]
本考案の内燃機関用動弁装置は、ロッカアーム軸受１０を溝のない平軸受とし 、ロッカシャフトの給油孔９とバルブ回りへのロッカアーム給油孔８との連通を 間欠的にすると共に、前記ロッカシャフト給油孔を軸受荷重の大きい部分へ潤滑 油が十分に流れるように給油孔９を貫通孔としたことを特徴としている。 In the valve train for an internal combustion engine of the present invention, the rocker arm bearing 10 is a flat bearing without grooves. , the communication between the oil supply hole 9 of the rocker shaft and the rocker arm oil supply hole 8 around the valve. In addition to intermittent lubrication, the rocker shaft lubrication hole is used to lubricate areas with large bearing loads. A feature is that the oil supply hole 9 is a through hole so that oil can flow sufficiently.
【０００６】[0006]
ロッカアームの軸受溝を廃止したので軸受面積を増加でき、又ロッカアームか らバルブ回りへの給油が間欠的となるためロッカアームの軸受部への給油圧力が 増加し、又軸受荷重の高い下部軸受部への給油量が増加するようにしたので、該 軸受部の摩耗が減少する。 By eliminating the bearing groove on the rocker arm, the bearing area can be increased. Since the oil supply around the valve is intermittent, the oil supply pressure to the rocker arm bearing is reduced. In addition, the amount of oil supplied to the lower bearing section, where the bearing load is high, has been increased. Wear on bearings is reduced.
【０００７】 以下図１を参照し本考案の一実施例について説明する。 ロッカアーム軸受に従来設けられていた溝７が廃止され、ロッカシャフト１か ら軸受への給油孔９及びロッカアーム２からバルブ回りへの給油孔８は間欠的に 連通するようにあけられている。 またロッカアーム２の給油孔８とつながるロッカシャフト１の給油孔９はロッ カシャフト１を貫通するようあけられており、軸受荷重の大きい軸受下側へ十分 に給油されるようにしている。[0007] An embodiment of the present invention will be described below with reference to FIG. The groove 7 previously provided on the rocker arm bearing has been abolished, and the rocker shaft 1 The oil supply hole 9 to the bearing and the oil supply hole 8 from the rocker arm 2 to the valve area are intermittently filled. It is opened to communicate. Also, the oil supply hole 9 of the rocker shaft 1 connected to the oil supply hole 8 of the rocker arm 2 is connected to the oil supply hole 9 of the rocker shaft 1. It is drilled so as to pass through the shaft 1, and is sufficient to reach the lower side of the bearing where the bearing load is large. It is designed to be refueled.
【０００８】 次に前記実施例の作用について説明する。 （１）溝１０を廃止したので軸受面積が増加する。 （２）ロッカアーム２からバルブ回りの給油が間欠的となるため、軸受部１０へ の給油圧力が上昇する。 （３）ロッカシャフト１の給油孔９が貫通孔となり軸受荷重の高い下方部分へ潤 滑油が十分流れるようにした。 以上（１）〜（３）によりロッカアーム軸受１０への潤滑が十分となり、該軸 受部分の摩耗量の減少が実現できる。[0008] Next, the operation of the above embodiment will be explained. (1) Since the groove 10 is eliminated, the bearing area increases. (2) Since the oil supply around the valve from the rocker arm 2 is intermittent, the oil is supplied to the bearing part 10. The oil supply pressure increases. (3) The oil supply hole 9 of the rocker shaft 1 becomes a through hole to lubricate the lower part where the bearing load is high. I made sure that the lubricating oil flowed sufficiently. Through (1) to (3) above, the rocker arm bearing 10 is sufficiently lubricated, and the shaft It is possible to reduce the amount of wear on the receiving part.
【０００９】[0009]
ロッカアーム軸受に溝がなくなり、軸受面積が増加すると共に、ロッカアーム からバルブ回りへの給油を間欠的にしたため、軸受部への給油圧力が増加し軸受 部への潤滑油が行き易くなる。さらにロッカシャフトの給油孔を貫通孔として荷 重の高い下方部分へ十分の潤滑油が行くように構成したので、これらによりロッ カアーム軸受部分の摩耗量が少くなりその耐久性が向上し、サイレントエンジン が実現できる。 The rocker arm bearing has no groove, the bearing area increases, and the rocker arm Since oil is supplied to the valve area intermittently, the oil supply pressure to the bearing increases and the bearing This makes it easier for lubricating oil to reach the parts. Additionally, the oil supply hole of the rocker shaft can be used as a through hole for loading loads. The structure was designed so that sufficient lubricant goes to the lower part where the weight is higher, so the lock The amount of wear on the arm bearing is reduced and its durability is improved, resulting in a silent engine. can be realized.
