System for adjusting gap between machine components comprises hollow bolt with internal and external threads, second externally threaded bolt passing screwing into hollow bolt

摘要

The fine adjusting system for the distance between two machine components (1, 2) comprises a hollow bolt (5) with an internal (8) and external (4) thread. This passes through a threaded bore (3) in the first component (1). A second bolt (6) with an external thread (7) passes through a threaded bore in the second component and screws into the hollow bolt. The outer thread of the hollow bolt has a pitch P1 and the outer thread of the second bolt has a pitch P2, so that one turn of the hollow bolt adjusts the gap between the components by a distance of P1 - P2.
