Abstract
The hyperboloid (or concave) exhaust bellows includes a plurality of convolutions of varying heights arranged in a hyperboloid (or concave) configuration. The hyperboloid bellows has increased strength and resiliency in high stress environments due to the hyperboloid configuration of the convolutions. The hyperboloid bellows allows for increased lateral movement in the same axial space or envelope compared to the prior art. The hyperboloid bellows having the hyperboloid shaped expansion joint produces an excessive amount of lateral motion using a single ply to multi-plies metal expansion joint bellows.
Claims15
A bellows for use in an exhaust system, the bellows comprising:
- a first opening and a second opening, both the first opening and the second opening configured to connect to the exhaust system;
- and
- a plurality of convolutions extending between the first opening and the second opening, the plurality of convolutions varying in height, the plurality of convolutions arranged to form a curved plane, the curve plane being concave in shape along the entire length of the bellows;
- wherein the plurality of convolutions extending in heights provide for increased lateral movement in the same axial space compared to a bellows without convolutions varying in height.
A bellows for use in an exhaust system, the bellows comprising:
- a first opening and a second opening, both the first opening and the second opening configured to connect to the exhaust system;
- and
- a plurality of convolutions extending between the first opening and the second opening, the plurality of convolutions evenly spaced along the entire length of the bellows, the plurality of convolutions varying in height, the plurality of convolutions arranged to form a curved plane, the curve plane being hyperboloid in shape;
- wherein the hyperboloid bellows is not restrained in motion;
- wherein the plurality of convolutions extending in heights provide for increased lateral movement in the same axial space compared to a bellows without convolutions varying in height.
