Abstract
PURPOSE: To reduce concentration of the stress caused by an impulse in the both end portions of bellows and prolong the life of the bellows, by forming it so that radii of curvature of ridges and bottoms of its wave shaped portions near its both ends are gradually increased from the middle portion toward the both ends.
CONSTITUTION: Radii r1, r2, r3 of curvature of ridges 3 and bottoms 4 of wave shaped portions 2 of bellows 1 near its both ends are formed so as to be gradually increased from radii r0 of curvature of ridges and bottoms of wave shaped portions of the bellows 1 near its middle portion toward its ends. Accordingly, as spring constant near both ends of the bellows is gradually increased from that near its middle portion a load caused by an impulse, and the stress by a load at the time of expanding or contracting the bellows 1 do not concentrate in the end portions, otherwise relieved, dispersed and absorbed properly. Thereby, the life (the durability) of the bellows 1 can be improved.
