Abstract:
A linear guide device, comprising:a guide rail having a longitudinal axis,at least one guide carriage guided on said guide rail in the direction of said longitudinal axis by means of at least one rolling member loop circulating in a circulation space of said guide carriage,said rolling member loop including a bearing row of rolling members in simultaneous engagement with a bearing track of said guide rail and a bearing track of said guide carriage, further a returning row of rolling members and two arcuate rows of rolling members,said guide carriage comprising a carriage main body in the longitudinal region of said bearing row of rolling members and end units at the axially spaced ends of said carriage main body,reversing guides for said arcuate rows of rolling members being formed at least partly on said end units,a lubricant demand existing on at least a part of the roll surfaces of the linear guide device,a lubricant path system being provided in said guide carriage for satisfying said lubricant demand,said lubricant path system extending from a lubricant supply space of said guide carriage to roll surfaces,said lubricant path system being accommodated at least in part in a boundary region between at least one end unit and said carriage main body,wherein a lubricating oil supply line, which is connected to said lubricant supply space and extends at least in part in said boundary region approximately in circumferential direction of said guide rail, is formed at least on a part of its length of a lubricating oil supply capillary line which supplies lubricating oil irrespective of a pressure difference, said lubricating oil supply capillary line being in licking contact with rolling members of said at least one rolling member loop or with said bearing track of said guide rail in at least one licking region.
