WORM TYPE GEAR MOVER ASSEMBLY

摘要

A mover assembly (16) that moves or positions an object (12) includes a mover output (32), a gear (238), and an assembly output (28) that is coupled to the object (12). The mover output (32) is rotated. The gear (238) engages the mover output (32) so that rotation of the mover output (32) results in rotation of the gear (238). The assembly output (28) is coupled to the gear (238) so that rotation of the gear (238) results in movement of the assembly output (28) along an axis (28A). The mover assembly (16) can include a rotation inhibitor (30) that inhibits rotation of the assembly output (28) and allows for movement of the assembly output (28) along the axis (28A). The mover output (32) can include a worm (236) that engages the gear (238) so that rotation of the worm (236) about a worm axis (236A) results in rotation of the gear (238) about a gear axis (238A) that is different than the worm axis (236A).
