Mastication simulating apparatus for e.g. human, has driving units driving disk in rotation with respect to another disk around common axis, and translation units parallely translating disks to common axis

摘要

The apparatus has simulating units for simulating a movable lower jaw and a fixed upper jaw, where the units are formed by two disks (21, 22) parallel and aligned on a common axis (A-A'). Driving units constituted of a driving device (16), an electric motor (17), a rotating ball (18) and a notched pulley (19), drive the disk (21) in rotation with respect to the other disk around the common axis, and translation units constituted of a splined shaft (12), a jack (13) and an electrical motor (14), parallely translate the disks to the common axis.
