Abstract
A mechatronic device, such as a rod-style linear actuator, is disclosed having a shock absorber. In embodiments, the device includes a threaded screw that, when rotated, is also forced to move linearly. A drive nut assembly is disposed about the screw and includes a planetary roller assembly with planetary rollers with threading that engage the threaded screw. The shock absorber is disposed linearly adjacent to the planetary roller assembly and is configured to absorb and/or dissipate a static shock load transmitted through the device so as to protect the screw. The shock absorber may be a polymeric cylindrical member disposed about the screw and contacting the planetary roller assembly via springs.
