Title:
PRE-COMPRESSION DEVICE FOR ROTATIONALLY GUIDED ROLLER SCREW MECHANISM
Document Type and Number:
Japanese Patent JP2015218904
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pre-compression device for rotationally guided roller screw mechanism.SOLUTION: This invention relates to a linear actuator comprising a roller screw mechanism 24 guided to be rotated in respect to a structure 26 by two angular contact ball bearings 33a, 33b, and the roller screw mechanism comprises an endless screw 25 and rollers 28 placed between the two threaded rings 29a, 29b connected to each other to be rotatably and freely translated. Each of the threaded rings is fixed to an inner ring of the angular contact ball bearing, the linear actuator includes one pre-compression device 36 capable of applying a load between the two outer rings 32a, 32b of the angular contact ball bearing, a load is applied to the roller screw mechanism and a rotating guide of the roller screw mechanism in respect to the structure can be performed simultaneously.
