<p>A phase shift mechanism (A) for controlling a phase shift angle between a camshaft (12) and a drive (10) comprises a planetary gear train ( 20). The planetary gear train (20) has first and second planet gears (34, 26) that are united to rotate about a common axis at the same angular velocity, and a carrier (32) which includes a first planet bearing (62) and a second planet bearing (64) on which the united first and second planet gears ( 34, 36) respectively rotate and a locking mechanism (24) carried by the carrier (32) for locking the planetary gear train (20) in a locked condition by preventing the planet gears (34, 36) from rotating relative to the carrier (32 ) such that the phase shift angle remains the same and the output shaft 26 rotates with the input shaft (18) at the same angular velocity.</p> |
