Ring gear for planet gear of e.g. gearbox, of motor car, has coupling element whose cross-section is smaller than cross-section of space defined by recesses, where coupling element is received in space defined by recesses

摘要

The gear (1) has an inner ring (20) whose radial outer surface (21) is provided with first and second recesses (51, 53) that are in intervention with third and fourth recesses (52, 54) formed in a radial inner surface (32) of an outer ring (30). A coupling element (40) stands in an active connection with the second and fourth recesses, where a cross-section (Q-K) of the coupling element is smaller than a cross-section (Q-E) of a space defined by the second and fourth recesses and in which the coupling element is received.
