|
Af |
Cross sectional metal area of one reinforcing fastener. |
|
|
Db |
Inside diameter of bellows convolution. |
|
|
Dm |
Mean diameter of bellows convolution. |
|
|
Dr |
Cross sectional diameter of the reinforcing ring. |
|
|
Lc |
Bellows collar length. For the toroidal bellows, Lc is determined by dividing the collar cross section area with the collar thickness. |
|
|
Lf |
Effective length of one reinforcing fastener. |
|
|
Lt |
End tangent length. |
|
|
Lw |
Distance between toroidal bellows attachment welds. |
|
|
q |
Convolution pitch. |
|
|
r |
Mean radius of toroidal bellows convolution. |
|
|
t |
Bellow nominal thickness of one ply. |
|
|
tc |
Collar thickness. |
|
|
w |
Convolution height. |
