Abstract

PURPOSE: To prevent a retainer of a bearing from getting loose, by limiting the relative displacement of a linear guide and retainer to about two to one by means of a set of link, pulley and gear.
CONSTITUTION: A linear guide 5 is shifted being held by a table 6, while the other linear guide 7 is fixed to a bed 20. As the table 6 is shifted, a rod 8 fixed to the table moves a connecting rod 9 which is allowed to turn and axially slide at nodes A, B but only to turn at a node C. A rod 10 extended from a retainer 2 is so fixed halfway to the connecting rod 9 that it can slide in the axial direction of the rod 9, keeping their relative positional relation at two to one. This can keep the displacement rates of table 6 and retainer 2 at two to one, which prevents the retainer from getting loose.
