Description

The needle roller bearing as it is manufactured in today's form, is primarily to be regarded as a floating bearing, i.e. it cannot absorb axial forces. In all door pulls that the needle bearing has to have, this is its greatest disadvantage. Admittedly, on the rolling bearing market Combined needle roller bearings are offered, which absorb axial forces on one side, but have significant deficiencies. These are:

a) with larger axial forces, complex external shape and complex internal structure;

b) with smaller axial forces you can only use them as a manager and exist e.g. at combined needle ball bearings, there is an inner risk of the needles setting if the balls are also subjected to radial loads.

The needle-axial-radial bearing, or NAH bearing for short, designed by me should eliminate all of these disadvantages.

The NAR bearing consists of an inner and an outer race, each with a board fixed on one side; with sheet metal design with a shelf fixed on both sides. Between the inner and outer ring there is a ring with cylindrical rolling elements for mounting arranged radial forces.

The unilateral axial forces are generated by a ring of rolling elements recorded between the two shelves of the interior and roll off the outer ring.

The opposite side of the bearing, which is not intended to absorb the axial forces, is closed with a locking ring. or in the case of sheet metal, the outer ring or the inner and outer rings are bent to form a locking rim. In this way I achieve a rolling bearing which:

a) an installation unit corresponding to the ball bearing bUdeXt;

b) the unresponsiveness of the normal needle roller bearing the sensitivity of the usual combined bearings; The risk of setting and misalignment during installation are avoided;

PUf
c (is easier to install than the usual combined bearings;

d) are provided with all radial clearance values of normal bearings can}

e) absorbs higher axial forces in contrast to needle ball bearings;

f) as a transit warehouse and with a lid on, if a closed construction is not already chosen than

Can serve repository in which all complicated sealing problems are eliminated;

g) lower in price but at most equal to the combined bearings that are on the market.
