Abstract
A bellows structure for use in high velocity, linear motion applications and which incorporates self-damping is disclosed. The bellows structure utilizes a plurality of thicker convolutions at each end of a regular bellows section to join the bellows section to its terminations. The thicker convolutions are distributed asymmetrically with the greater number of thicker convolutions being placed adjacent the stationary end of the bellows. The bellows structure increases the energy absorption capabilities of the stationary end of the bellows, and causes the intersecting, energy-absorbing waves traveling through the bellows section to intersect more frequently resulting in their internal cancellation.
Claims1
A bellows structure comprising a first bellows section comprising a plurality of convolutions formed from diaphragms having a first thickness, a second bellows section comprising a plurality of convolutions formed from diaphragms having a second thickness, and a third bellows section comprising a plurality of convolutions formed from diaphragms having a third thickness, said first thickness of said diaphragms forming said plurality of convolutions in said first bellows section and said second thickness of said diaphragms forming said plurality of convolutions in said second bellows section being greater than said third thickness of said diaphragms forming said plurality of convolutions in said third bellows section, said third bellows section being interposed between said first and second bellows sections, and wherein the number of convolutions within said first bellows section is greater than the number of convolutions within said second bellows section.
