ROLLING ELEMENT HOLDING BELT FOR LINEAR MOTION GUIDE, LINEAR MOTION GUIDE, AND METAL MOLD FOR MANUFACTURING ROLLING ELEMENT HOLDING BELT

摘要

PROBLEM TO BE SOLVED: To provide a rolling element holding belt for a linear motion guide smoothly circulating a rolling element holding belt even if burrs occur, a linear motion guide, and a metal mold for manufacturing a rolling element holding belt.;SOLUTION: The linear guide (linear motion guide) comprises an endless circulation path for circulating balls 46 while rolling. The linear guide further comprises spacer parts 51 interposed in the endless circulation path between adjacent balls 46 and a rolling element holding belt 50 having connection arm parts 52 for connecting the space parts 51 to each other. The spacer part of the rolling element holding belt 50 is so formed that the surface 54 thereof facing the side of the adjacent balls 46 has a non-contact surface 55 not in contact with the adjacent balls 46 and a contact surface 56 recessed from the non-contact surface 55 and having a portion in contact with the adjacent balls 46.;COPYRIGHT: (C)2008,JPO&INPIT
