Abstract
According to one embodiment, a bearing features an elastomeric portion having an opening therethrough, a member disposed within the opening of the elastomeric portion, and a separation feature disposed between the member and the elastomeric portion. The member comprises a conical body portion arranged such that an interior diameter of the conical body portion is smaller than an exterior diameter of the conical body portion. The separation feature prevents contact between the member and the elastomeric portion.
Claims28
A bearing, comprising:
- an outer housing having an opening therethrough;
- an elastomeric portion disposed within the opening of the outer housing and in contact with the outer housing, the elastomeric portion having an opening therethrough;
- a separation feature disposed within the opening of the elastomeric portion and in contact with the elastomeric portion, the separation feature having an opening therethrough;
- and
- a member disposed within the opening of the separation feature and in contact with the separation feature, the member comprising a conical body portion arranged such that an interior diameter of the conical body portion is smaller than an exterior diameter of the conical body portion,
- wherein the separation feature is configured to prevent contact between the member and the elastomeric portion.
