で手間がかかる。 When a gear shaft with gears attached is rotatably mounted in a case and lubricating oil is sealed in the case to lubricate the gears, press-fit the oil seal and bearing side by side into the shaft hole provided in the case. The gear shaft is supported by a bearing, and is sealed by an oil seal to prevent lubricating oil from leaking. In this case, an inner flange is integrally provided on one side of the shaft hole of the case, and the oil seal driven into the shaft hole is positioned by protruding from the inner flange. However,
The oil seal needs to be replaced when the lip strip wears out, and when removing the oil seal, a sharp metal tool must be applied to the oil seal from the inner flange side and hammered out using a hammer or the like. However, since there is an inner flange, the area where the metal fitting covers the oil seal is small, so when it is hammered out, it may come off and damage the inner flange or shaft hole, making the work difficult and time-consuming.
この考案は、かかる点に鑑み改善したもので、
以下図面に示す本考案の実施例について説明す
る。 This idea is an improvement based on these points.
Embodiments of the present invention shown in the drawings will be described below.

い。 An inner flange 3 is provided on one side of the shaft hole 2 of the case 1, and an oil seal 4 is press-fitted into the shaft hole 2 by driving or the like.
Abut the end face against the inner flange 3. In addition, oil seal 4
A bearing 5 is press-fitted into the shaft hole 2 inside the shaft hole 2 in line with the oil seal 4, and a shaft 6 is inserted therethrough for shaft mounting.
However, in the present invention, in the inner flange 3 of the case 1,
A plurality of radial grooves 7 are provided. Groove 7 is case 1
It can be provided by casting when casting from light alloy.
オイルシール４をケース１に嵌着するときは、
内側のベアリング５側から軸孔２に圧入して、内
鍔３に突当てて位置決めをする。このときは、内
鍔３は外側にあつて、内鍔３に関係なく作業がで

３や軸孔２を傷つけるようなことが防げ、作業も
容易にできる。 When fitting the oil seal 4 into the case 1,
Press fit into the shaft hole 2 from the inner bearing 5 side and position it by hitting the inner flange 3. At this time, the inner flange 3 is on the outside, and work can be done regardless of the inner flange 3. When removing the oil seal 4 for replacement, the oil seal 4 must be punched out from the inner flange 3 side. At this time, insert the tip of a sharp tool such as a screwdriver into the groove 7, apply it to the end face of the oil seal 4, and apply an impact with a hammer or the like to remove it. The tools are replaced one after another in the groove 7, and the oil seal 4 is driven without being tilted. The tip of the tool is
Since it can be sufficiently applied to the oil seal 4 through the groove 7 and will not come off due to impact shock, etc., damage to the inner flange 3 and shaft hole 2 can be prevented and the work can be done easily.
以上説明したように、この考案は、ケース一側
に内鍔を設けた軸孔を設け、該軸孔に内鍔に突当
てるようにしてオイルシールを圧入するようにし
たものに於て、内鍔に複数の放射状の溝を設けた
ので、オイルシールを抜取る場合、鋭利な工具の
先端を内鍔の溝に通して、十分オイルシールに掛
けることができ、衝撃を加えた場合外れ難い。こ
のため、作業が容易で、工具が外れてケースの軸
孔や内鍔を傷つけることが防げる。 As explained above, this invention provides a shaft hole with an inner flange on one side of the case, and press-fits an oil seal into the shaft hole so as to abut against the inner flange. Since a plurality of radial grooves are provided on the flange, when removing the oil seal, the tip of a sharp tool can be passed through the groove of the inner flange and sufficiently hooked on the oil seal, and it will not easily come off when an impact is applied. This makes the work easier and prevents the tool from coming off and damaging the shaft hole or inner flange of the case.
