Axially telescoping coil support - has segments on end ring fitting between sleeve ribs on other end ring

摘要

The axially-telescoping coil support has portions sliding together and fixed to first and second end rings. Those on the first end ring are supporting ribs (10) running for the whole length of a cylindrical sleeve (3), and between which on the outside there fit sleeve segments (4) on the second end ring (2), with axial edges adjacent to the ribs (18). Guide members on the segments work in mating ways in the sleeve (3). These ways can have bars joined to them by ribs, engaging in ways in the sleeve (3). These ways can have bars joined to them by ribs, engaging in ways in the segments. The members and ways can be of dovetail or T-section.
