Embodiment Construction

[0019] figure 1 The shown linear guide unit according to the invention has a guide frame 2 guided longitudinally on a guide rail 1 . Rolling bodies, not shown further here, roll under load on the running surfaces of the guide rails and guide frames in a known manner. The rolling surfaces define a load channel. The rolling element rings are arranged in endless rolling element channels, wherein each rolling element channel has the already mentioned load channel, return channel and two reversing channels endlessly connecting the return channel and the load channel. The reversing channel and the return channel are completely arranged in the guide frame 2 .

[0020] The linear guide unit according to the invention also contains a length measuring system which has a measuring head 3 and a measuring tool 4 . The length measuring system works on the inductive principle. The measuring device 4 is designed as a round rod. The metering tool 4 is formed of a stainless steel tube in ...

Abstract

Disclosed is a linear guide unit, comprising a guiding carriage (2) that can be moved in the longitudinal direction on a guide rail (1) and a length measuring system provided with a measuring head (3)that cooperates with a material measure (4) arranged parallel to the guide rail (1), the material measure (4) being located at a distance from the guide rail (1) and arranged within the clearance profile of the linear guide unit.

Description

technical field [0001] The invention relates to a linear guide unit with a length measuring system. Such linear guide units are used, for example, in the machine tool construction industry, or in transport devices on assembly lines, or in wood processing. The length measuring system realizes the precise positioning of the guide frame at the predetermined position. Background technique [0002] A linear bearing with a measuring device is known, for example, from DE 199 41 587 A1, in which the guide frame is arranged movably on a guide rail. A measuring head is arranged on the end face of the guide frame. The guide rail is provided with a groove on its upper side, into which the metering device is inserted. In this case, the metering tool is formed in one piece with the cover strip, which is held in a force-tight manner in the groove of the guide rail. As an alternative, the gauge can be glued to the flange strip. When it is time to change the gauge, this can only be achi...
