摘要： A spacing ring for placement between a radially inwardly facing annular surface on a first member and a radially outwardly facing annular surface on a second member to maintain the first and second members in predetermined radially spaced relationship. The ring consists of a plurality of matted threads formed into an annular configuration. The ring has a radially inwardly facing surface to surroundingly engage the radially outwardly facing annular surface on the second member and a radially outwardly facing surface to be surroundingly engaged by the inwardly facing annular surface of the first member with the radially inwardly facing annular surface on the first member and the radially outwardly facing annular surface on the second member in axially overlapping relationship. The invention also contemplates a method of forming the spacing ring. The wool material is wrapped around an annular surface ona core bar. The wool material is both radially and axially compacted on the core bar with a predetermined compressive force.
摘要翻译：间隔环，用于放置在第一构件上的径向向内面对的环形表面和第二构件上的径向向外的环形表面之间，以将第一和第二构件保持在预定的径向间隔关系。该环由形成为环形构造的多个无衬线构成。环具有径向向内的表面，以周向地接合在第二构件上的径向向外面对的环形表面和径向向外的表面，以与第一构件的面向内的环形表面周向地接合，其中径向向内的环形表面第一构件和第二构件上的径向向外的环形表面以轴向重叠的关系。本发明还考虑了形成间隔环的方法。羊毛材料缠绕在芯棒上的环形表面上。羊毛材料在芯棒上以预定的压缩力径向和轴向压实。

摘要： A spacing ring for placement between a radially inwardly facing annular surface on a first member and a radially outwardly facing annular surface on a second member to maintain the first and second members in predetermined radially spaced relationship. The ring consists of a plurality of matted metal threads formed into an annular configuration. The ring has a radially inwardly facing surface to surroundingly engage the radially outwardly facing annular surface on the second member and a radially outwardly facing surface to be surroundingly engaged by the inwardly facing annular surface of the first member with the radially inwardly facing annular surface on the first member and the radially outwardly facing annular surface on the second member in axially overlapping relationship. The invention also contemplates a method of forming the spacing ring. The wool material is wrapped around an annular surface on a core bar. The wool material is both radially and axially compacted on the core bar with a predetermined compressive force.
