Problems solved by technology

This deformation is difficult or even impossible to monitor
This creates an increased risk that the elastomer spring comes into contact with the bearing cap of the rolling bearing or other rotating parts of the structural assembly under load
A further disadvantage is that the spring curve is not linear due to the deformation behavior of the elastomer spring

Embodiment Construction

[0033] The structural component 5 has a shaft 30 which is arranged concentrically around the axis 3 and extends in a longitudinal direction 32 . Roller bearing 2 is arranged on shaft 30 concentrically to axis 3 . The rolling bearing 2 shown here has balls as rolling bodies 24 . The terms rolling body and ball are used synonymously below. However, the invention also extends to rolling bearings 2 having other, for example cylindrical or conical rolling bodies 24 .

[0034] The balls 24 are arranged between an inner ring 22 arranged in a rotationally fixed manner on the shaft 30 and an outer ring 21 arranged in a rotationally fixed manner on the housing part 4 . In order to prevent the balls 24 from becoming dirty and falling out, bearing caps 23 are provided on both sides of the balls 24 , which extend transversely (perpendicularly) to the shaft 30 and between the inner and outer rings 21 , 22 . The bearing caps 23 arranged on both sides of the sphere 24 are arranged inwardly...

Abstract

The present invention relates to a spring for a preloaded bearing, in particular a rolling bearing, with an elastomeric core, wherein the elastomer core comprises a support sleeve of a hardenable material is disposed cohesively, and is formed less elastic than the elastomeric core. The present invention also relates to a structural component, which comprises a housing member, a bearing and the spring.

Description

technical field [0001] The invention relates to a spring for pretensioning a rolling bearing comprising an elastomer core. The invention also relates to a structural assembly with springs and rolling bearings. Background technique [0002] Springs made of elastic material, in particular rubber, are generally used for pretensioning rolling bearings. Such an elastomer core also has good cushioning properties in addition to good elastic properties. They play a role of good vibration damping and noise reduction. [0003] But the forces acting on the elastomeric core are usually not evenly distributed over the entire cross-section. This reduces the shape stability of the spring and the spring deforms under load. This deformation is difficult or even impossible to monitor. This creates an increased risk that the elastomer spring will come into contact with the bearing shield of the rolling bearing or other rotating parts of the subassembly under load. Furthermore, it is disa...
