USA TOLERANCE RINGS and Ididit, a manufacturer of custom steering columns for hot rod, race, show and specialty vehicles based in Tecumseh, MI, collaborated to develop a collapse ring for steering columns. The ring, designed to keep a driver safe in a front-end collision, is available chrome-plated or powder-coated and keeps the existing low-cost 16-gauge DOM tubing. A flanged tolerance ring with an advance wave configuration is fitted between the tubes and retained by the outer tube while the inner tube slips axially inside the ring. The target axial collapse force of 550 lb ± 100 lb is achieved while maintaining ease of assembly within components having a stack up tolerance of .020 inch.
Industrial workplaces are governed by OSHA rules, but this isn’t to say that rules are always followed. While injuries happen on production floors for a variety of reasons, of the top 10 OSHA rules that are most often ignored in industrial settings, two directly involve machine design: lockout/tagout procedures (LO/TO) and machine guarding.
