入品又は射出品の外側の周面から、若しくは孔か
ら半径方向の間隔をおいて側面からしか行なえな
いからである。Difficulties arise when implanting hole reinforcing sleeves of this type by injection or injection. This is because, due to the shape of the hole reinforcing sleeve, injection or injection of the polymeric material can only take place from the outer circumference of the injection or injection article or from the side at a radial distance from the hole.

か阻止することができない。[0004] In such working conditions, not only the flow conditions and directionality of the material are unfavorable, but also uncontrollable distortion occurs, and furthermore, depending on the shape of the injected or injection product, fluctuations in volume must also be taken into account. Must be. Rotationally symmetrical injection or injection parts formed in this way have poor rotational properties due to unbalance and/or radial runout, especially at high rotational speeds. On the other hand, distortion of the injection or injection part relative to the bore reinforcing sleeve can only be prevented by special measures.

段を提供することにある。[0005] It is therefore an object of the present invention to avoid the above-mentioned drawbacks and to produce a metal hole-reinforcing sleeve with a radially outward edge by means of a polymeric material in a simple and rapid manner by injection or injection. It is an object of the present invention to provide a means for embedding and fixing in a hole of an injection product or an injection product in a relatively rotationally immovable manner.

At the same time, the window-like cutout filled with polymer material strengthens the ability to prevent relative rotation between the hole reinforcing sleeve and the injected or injection part.

る。[0008] If the hole reinforcing sleeve is provided with a plurality of recesses in its central part, dimensional tolerances between the hole reinforcing sleeve and the shaft inserted therein are additionally compensated for.
This is because the polymer material in the cutout area extends inwardly beyond the bore diameter of the bore reinforcing sleeve.
