Linear guide feed-modulus with guide body as well as support arm therefor

摘要

The linear guide feed module has a tubular boom movable along a movement axis. A housing encompasses the tubular boom so that the boom is travelable out of and into the housing along the movement axis. A drive unit drives the boom to move in relation to the housing. Two recirculating rolling element rows support the boom in the housing for its movement in relation to the housing along the movement axis and spaced apart from each other in a circumference direction around the movement axis. Each recirculating rolling element rows have a force-loaded rolling element carrying segment extending in a direction of the movement axis and an unloaded rolling element return segment. A guide body encompasses the boom in segments in the circumferential direction. The guide body is provided in the housing and has rolling element passages of the rolling element return segments formed into it as well as raceways on a housing side of the rolling element carrying segments of the two rolling element rows.
