いようになっている。In such a motor with reducer, the output shaft 4 is rotatably supported by the oil-impregnated bearing 3 mounted on the bearing bush 2 provided in the reducer housing 1 and the rear bearing plate 6 spaced by the spacer 7. The output shaft gear 9 integrally fixed to the output shaft 4 meshes with the pinion 11 provided on the output shaft of the electric motor 10, and the rotation of the electric motor 10 is decelerated and transmitted to the output shaft 4. . An oil seal 5 is attached to the front part of the oil-impregnated bearing 3 so that oil inside the reduction gear transmission does not leak through the oil-impregnated bearing.

大きなスラスト荷重がかかった場合には上記Ｏリングが
圧縮破損されるという欠点があった。However, in such a conventional technique, the oil seal 5 occupies the space in front of the oil-impregnated bearing 3 in the bearing bush 2, so that the effective length of the oil-impregnated bearing 3 is reduced and the life is shortened. The output shaft gear 9 vibrates in the rotational direction due to the uneven rotation of the shaft and the machining error of the output shaft gear, and vibrates particularly between the output shaft gear and the pinion 11 that meshes with the output shaft gear to generate a so-called rattling noise. There is a problem. Among the above problems, it is conceivable to insert an O-ring on the opposing surface of the oil-impregnated bearing 3 and the output shaft gear 9 in order to prevent the generation of rattling noise, but when a large thrust load is applied to the output shaft 4. Had a drawback that the O-ring was damaged by compression.
本考案は上記の問題を解決したものである。The present invention solves the above problems.

る。The motor with reduction gear of the present invention includes a reduction gear output shaft, an oil-impregnated bearing rotatably supporting the output shaft, an output shaft gear fixed to the output shaft, and an oil-impregnated bearing facing the output shaft gear. It is characterized in that it comprises a recess formed on the end face, an O-ring having a part thereof inserted into the recess, and a spacer provided on the end face of the output shaft gear facing the O-ring.

った場合でもくぼみによってその圧潰が防がれる。In the motor with reduction gear of the present invention, the output shaft is supported by the oil-impregnated bearing whose effective length is not reduced, and the friction load due to the O-ring prevents the generation of rattling noise even when there is no load. Further, even if a large thrust force is applied to the output shaft, the depression prevents the crushing.
以下図面によって本考案の実施例を説明する。 An embodiment of the present invention will be described below with reference to the drawings.

間座14を設ける。In the present invention, as shown in FIG. 1, an oil seal 5 is not used, but an oil-impregnated bearing 3 that is longer in the axial direction is used, and it is positioned between the opposed surfaces of the oil-impregnated bearing 3 and the output shaft gear 9. The O-ring 12 is wound around the outer circumference of the output shaft 4 and the recess 13 into which a part of the O-ring 12 can be inserted is formed on the end surface of the oil-impregnated bearing 3, and the collar or spacer 14 is formed on the opposite surface of the output shaft gear 9. To provide.

また、出力軸４に大きなスラスト荷重がかかってもＯリ
ング12が完全に潰されるおそれはなくなり、油漏れ防止
を完全に行うことが出来る。Since the electric motor with reduction gear of the present invention has the above-mentioned structure, oil leakage can be prevented by the O-ring 12, and the oil-impregnated bearing 3 which is long in the axial direction can be used. Therefore, the life of the oil-impregnated bearing can be extended, and A frictional load is generated by the O-ring 12 between the outer circumference of the output shaft 4 or the end surface of the output shaft gear 9 and the oil-impregnated bearing 3, whereby the rattling noise is not always generated.
Further, even if a large thrust load is applied to the output shaft 4, there is no possibility that the O-ring 12 will be completely crushed, and oil leakage can be completely prevented.

There are great benefits such as being able to do it.
