Roller turret including rollers mounted on support portions of roller shafts, which are eccentric with respect to stud portions fixed in holes in turret body, and method of manufacturing the roller turret

摘要

A roller turret including a turret body having a plurality of mounting holes formed therein such that the mounting holes are arranged in a rotating direction of the turret body, a plurality of roller shafts each including a roller support portion and a stud portion eccentric with respect to the roller support portion and fitted in the corresponding mounting hole, a plurality of rollers rotatably mounted on the roller support portions of the respective roller shafts, and a device provided for each mounting hole, for fixing the stud portion to the turret body, at a desired angular position of the corresponding roller shaft. The roller turret may be manufactured by a method which includes the steps of preparing the turret body, preparing the roller shafts having the rollers rotatably mounted on the roller support portions, preparing a preliminary roller turret assembly wherein each roller shaft is rotatably fitted at the stud portion in the corresponding mounting hole, adjusting an angular pitch of the adjacent rollers, by rotating the roller shafts, and fixing all of the roller shafts to the turret body after the angular pitch adjusting step. Also disclosed are various devices including the roller turret and methods of manufacturing these devices.
