Description

The present innovation relates to a roller bearing, in particular for Wheel bearings «consisting of an old paddling inner ring« a Outer ring and rolling elements arranged in between in one or more rows.

A bearing of this type is widely in the special section of the '' ball bearing magazine " (April 1972) on page 18. This storage unit is based on & em principle that the bearing is designed as a double row angular contact ball bearing, where the partial crown diameter, i.e. the diameter of the ball set, is possible is kept large. The rotating outer ring as well as the rotating inner ring are provided with flanges. In the splash of the inner ring and also in the Plansch of the outer ring are recesses for receiving screw bolts Attachment of the storage unit provided, which must be easily accessible. the The same as on the bearing rings can also be in the form of projections or the like be formed.

The task of the present innovation is to provide a rolling bearing that is more compact and more capable of bearing loads within the dimensions of the already known bearing types to accomplish.

This object is achieved according to the present innovation in that the zct To accommodate fasteners for the wheel in the flange of the Iunenrin & ds Recesses so slightly above the inner ring raceway for the Rolling bodies are arranged that while maintaining the in the known rolling bearings for wheel bearings common external dimensions (external diameter and width)

the pitch circle diameter for the fastening elements and the pitch circle diameter the rolling elements are so close to each other that the distance between them the two pitch circles reached a minimum value, and that the number of rolling elements is increased.

When comparing the well-known Lagar with the new, iQ warehouse of the same external dimensions (outside diameter and width) and the same ball size, the following advantages emerge. Thanks to the larger partial camber of the rolling elements in the new design, the number of rolling elements and the moment load on the bearing itself can be increased. This results in an approximately 50 percent increase in the dynamic load rating compared to the previously known bearing designs. The static load capacity can also be increased by 30%. In addition, the material joints in the surface of the inner ring are reduced by approx. 40% as a result of the decrease in the moment load.

The listed values refer to a storage unit for a vehicle, that works under normal conditions.

The firing is described below with reference to the accompanying drawings, described in more detail «where

Figure 1 shows a cross section through a known storage unit and Figure 2 show a cross section through a camp according to the innovation.

In Figure 1, 1 denotes the flanged inner ring of a known one Bearing on which the vehicle wheel is screwed into the threaded holes 4 are screwed in, is attached. In the flanged outer ring 2 5 screw bolts for fastening the bearing unit to the wheel suspension of the vehicle are screwed into the Oewlndbohrungen. The distance H between the pitch circle of the holes in the inner ring and the pitch circle of the rolling elements is relatively large due to the design of the inner ring flange.

Figure 2 shows the construction of the new layer »being the Tellkreisdurohaesser The dp of the fixing elements 6 is so dug up in relation to the Tellkrelsduronaeaser Dr the rolling element, the distance M small 1st and daduroh It is advantageous to use a short lever for the Planohert. Furthermore arises a larger TeilkreledurobJMseer for the rolling elements 3, which increases the service life of the camp is increased

The old flange offset inner ring is also old 1 »the outer ring old 2 designated. The inner longitudinal flange has bores »In welohe confirmation elements 6, which in this "case are designed as bolts" are used " Among other things, attach the Fahrseug to the Lagerelnhelt on this catfish "The inner ring is old threaded holes 5" in which Bolsen sur attachment the bearing unit can be screwed into the rahrseugfsderung or dergleiohen can * Sin rlngförsdger Vorsprung 7 serves susasswn old dea Innenrlngflansoh sua centering of the Fahrxeugrades and / or the Breassoheibe of the wheel · The Outside 2 is provided with a projection 8, which is a diohtungseleaent 9 »old one or more floating lips IO attached 1st. The waterproofing Is designed so that it acts axially »But there is also a seal.

The building is not limited to the organized special-level execution type and can be varied within the scope of the following claims will.
