Title: Internal partition method for hollow cylindrical member
Inventor: HONDA SHUNICHI
IPC: F16J3/02
Filed: 1988-02-02
Abstract: PURPOSE:To partition a hollow member without deformation by inserting a circular partition member, equipped at the edge with a rim extending in the axial direction, in a ring groove having a greater dia. than the major dia. part adjoining to the shoulder surface of the minor dia. part in such a manner as contacting this shoulder surface, applying a load on the rim part, deforming it, and fixing to the groove. CONSTITUTION:A ring groove 4 having a greater dia. than the major dia. part 2 is provided adjoining to the shoulder surface 5 of the minor dia. part 3 of a hollow member with small wall thickness 1. A circular partition member 7 having a dia. equal to the major dia. part equipped at the edge with a rim 8 extending in the axial direction is inserted until contacting the shoulder surface 5. A load is applied to the rim 8, which deforms to intrude into the ring groove 4 and is caulked, and the major dia. part 2 and minor dia. part 3 are partitioned. Accordingly the stress generated in the wall part of the cylindrical member 1 due to deformation of the rim 8 is very small, and therefore the hollow cylindrical member 1 will scarcely be deformed.
