。Conventionally, as shown in FIG. 1, this type of lubricating oil pump has a drive shaft 1 rotatably supported in a crankcase 2 via a bearing 3, a pump casing 4 installed outside the crankcase, and a pump casing 4 mounted outside the crankcase. A pump cover 5 is bolted and fixed to the pump shaft 4, a pump shaft 6 is rotatably supported, the drive shaft 1 is connected to the pump shaft 6 so that the driving force is transmitted therefrom, and an inner rotor 7 is fitted. the inner rotor 7 is eccentrically engaged with the outer rotor 8 rotatably fitted to the pump casing 4;
Both rotors 7.8 are attached to the pump casing 4 and the pump cover 5.
Generally, those housed inside the enclosure are used.

ので、構造が複雑であるという問題があった。In order to improve this, for example,
There are pumps, such as the one described in Publication No. 6, that require less installation space by installing the pump casing inside the crankcase, but this also has a pump casing installed inside the inner rotor, similar to the one shown in Figure 1 mentioned above. Since the driving force is transmitted from the drive shaft, the discharge amount is small, and the structure is complicated because the pump casing is fitted into the crankcase and the pump cover is fixed to the pump casing. was there.

プを提供することを目的とするものである。The present invention was developed in view of the above-mentioned circumstances, and by directly fitting and fixing the outer rotor to the drive shaft, it requires less installation space, while reducing the discharge amount compared to a method that drives the inner rotor. The object of the present invention is to provide a lubricating oil pump for an internal combustion engine, which has a simplified structure by eliminating the need for a pump cover, and which reduces the risk of lubricating oil leakage.

An outer rotor is fitted and fixed within the shaft end of the drive shaft, an inner rotor that engages with the outer rotor is rotatably supported on the pump casing eccentrically from the outer rotor, and the pump casing is attached to the crankcase that supports the drive shaft. It is fixed.

以下、本考案の一実施例につき図面を参照して説明する
。Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

。In FIG. 2, reference numeral 11 denotes a drive shaft consisting of a crankshaft or a camshaft of an internal combustion engine, or to which driving force is transmitted.
1a is formed, and this large diameter portion 11a is connected to the crankcase 1.

ロータ１５の外歯歯車とが係合されている。A fitting hole 11 that opens at the shaft end formed in the large diameter portion 11a.
The outer rotor 14 is fitted and fixed in the inside b by appropriate means such as press fitting, and the inner rotor 15 is provided inside the outer rotor 14, and the internal gear of the outer rotor 14 and the external gear of the inner rotor 15 are engaged with each other. ing.

５はアウタロータ１４と偏心している。A pump casing 17 is fastened to the outer surface of the crankcase 12 via a backing 16 with bolts 18 , and the inner rotor 15 is rotatably supported on the pump casing 17 by a pump shaft 19 .
5 is eccentric to the outer rotor 14.

上記ポンプケーシング１７の内面には吸入凹部２０、吐
出凹部２１およびポンプ軸１９の取付孔２２がそれぞれ
形威しである。The inner surface of the pump casing 17 has a suction recess 20, a discharge recess 21, and a mounting hole 22 for the pump shaft 19, respectively.

得ることができる。The lubricating oil pump of the embodiment configured as described above is a trochoid type pump in which the outer rotor 14 has five teeth and the inner rotor 15 has four teeth, since the outer rotor 14 is driven by the drive shaft 11. The discharge amount can be approximately 1.25 times that of a pump that drives the inner rotor.

また、駆動軸１１の軸端部の大径部１１ａ、アウタロー

、小さいスペースに設置できる。Further, since the large diameter portion 11a of the shaft end of the drive shaft 11, the outer rotor 14, and the inner rotor 15 are built into the crankcase 12, it can be installed in a smaller space than the conventional one shown in FIG.

さらに、ポンプカバーを必要としないことにより、部品
数が少なく構成が簡単である。Furthermore, since a pump cover is not required, the number of parts is small and the configuration is simple.

きるという利点が得られる。The backing 16 is provided on the suction and discharge recesses 20 and 21 side, and the opposite side is sealed at the bottom of the fitting hole flb of the drive shaft 11, so that the mounting hole 22 of the pump shaft 19 is connected to the outer surface of the pump casing 17. Coupled with the fact that the outer rotor 14 is not opened on the drive shaft 11, there is less risk of lubricating oil leakage, and the outer rotor 14 is directly fitted to the drive shaft 11.
The advantage is that noise can be eliminated at the drive force transmission section from the pump to the pump.
