Title:
JOINTLESS BRAIDED SEALING RING AS WELL AS METHOD AND SPECIAL MACHINE FOR PRODUCING SUCH SEALING RING
Document Type and Number:
WIPO Patent Application WO/2011/160318
Kind Code:
A1
Abstract:
A jointless braided sealing ring as well as a method and a special machine for producing such a sealing ring are disclosed. The braided sealing ring adopts multi-layers braided structure comprising a number of continuously sleeved ring layers arranged from inside to outside. The innermost braided ring layer is used as a core. The tail end of the first braided ring layer (1) is sleeved on the head end of the first braided ring layer (1) and serves as the head end of the second braided ring layer (2) to implement continuously braiding without any interruption. The second braided ring layer (2) is sleeved on the first braided ring layer (1) and the third braided ring layer (3) is sleeved on the second braided ring layer (2). The Nth braided ring layer (4) is sleeved on the (N-1)th braided ring layer (5). N braided ring layers have (N-1) continuous intact braided ring layers. The tail end (8) of the outermost braided ring layer is superposed with the head end (7) of the innermost braided ring layer. Service life and sealing effect of the braided sealing ring are increased. A perimeter-limiting ring (6) is provided in the sealing ring to improve the dimensions precision of sealing ring, and avoid that the sealing ring deforms during braiding and reshaping.
