Elastic bearing
An elastic bearing comprising a mass having at least one mounting hole for a mounting sleeve, the mounting hole having a central longitudinal axis passing therethrough, at least one mounting sleeve having a collar section extending in the radial direction and a shaft section extending in the longitudinal direction, the mounting sleeve being fixed in the mounting hole, and an elastomeric body arranged on the outer circumferential side of the mounting sleeve. In an embodiment, the elastomer body has, in the region of the shaft section, a diameter-widening contour whose diameter increases with increasing longitudinal distance from the collar section, and the mounting hole having a diameter-widening contour which widens to the same extent as the diameter-widening contour of the elastomer body. In embodiments, the elastomer body is prestressed by the mass and the mounting sleeve at least in the radial direction.
1. An elastic bearing, comprising:
a mass having a mounting hole, the mounting hole having a central longitudinal axis,
a mounting sleeve having a collar section extending in a radial direction and a shaft section extending in a longitudinal direction, the mounting sleeve fixed in the mounting hole, and
an elastomer body arranged on an outer circumferential side of the mounting sleeve,
wherein the elastomer body has a collar portion abutting a step in the mounting hole, and the collar portion is configured to be over-pressed and briefly compressed during assembly, such that the collar portion pulls the mounting sleeve into an assembly position after the pressure is released; and
wherein the elastomer body has, in a region of the shaft section, a diameter-widening contour whose diameter increases with increasing longitudinal distance along a segment of the elastomer body from a position adjacent the collar section, and the mounting hole has a diameter-widening contour which widens to the same extent as the diameter-widening contour of the elastomer body, and the elastomer body is prestressed by the mass and the mounting sleeve at least in a radial direction.
2. The elastic bearing according to claim 1 , wherein the mounting sleeve has, in a region of the shaft section, a diameter-widening contour which expands to the same extent as the diameter-widening contour of the elastomer body.
3. The elastic bearing according to claim 1 , wherein the collar portion of the elastomer body is supported by the collar section of the mounting sleeve.
4. The elastic bearing according to claim 3 , wherein the diameter-widening contour and the collar portion preload the elastomer body in an axial direction.
5. The elastic bearing according to claim 1 , wherein the elastomer body has a cavity section which is supported by the shaft section and forms a cavity with the mounting hole.
6. The elastic bearing according to claim 1 , wherein the mounting sleeve has a support section extending in the radial direction, the support section provided adjacent to a largest diameter of the diameter-widening contour of the elastomer body.
7. The elastic bearing according to claim 1 , wherein the diameter-widening contour of the elastomer body is configured to include a truncated cone contour or as a partial ovoid contour.
8. The elastic bearing according to claim 1 , wherein the mounting sleeve has a central through-hole through which a fastening element can pass in the direction of a screw-on side.
9. The elastic bearing according to claim 1 , wherein the elastomer body or the mounting hole have an inlet chamfer for the respective other element of the elastomer body and the mounting hole.
10. The elastic bearing according to claim 1 , wherein the elastomer body and the mounting hole each have an inlet chamfer for the respective other element of the elastomer body and the mounting hole.
