摘要： A length-measuring device includes a scanning carriage for scanning a measuring graduation that is to be guided longitudinally in the measurement direction on a guide surface. A coupling couples the scanning carriage to a drive dog rigidly in the measurement direction and resiliently transversely to the measurement direction. A first spring is disposed between a connecting element of the coupling and the drive dog and exerts a pressure force on the scanning carriage at a first position so as to press the scanning carriage against the guide surface. A second spring is disposed between the connecting element and the scanning carriage. The second spring is spaced apart from the first spring in the measurement direction and exerts a pressure force on the scanning carriage at a second position spaced apart from the first position in the measurement direction so as to press the scanning carriage against the guide surface.

摘要： Disclosed is a linear guiding system (1) comprising at least one guide rail (2), at least one guide carriage (3) that is supported on the guide rail and can be moved therealong, and a device (5) for measuring a distance traveled by the guide carriage relative to the guide rail and/or determining a position of the guide carriage relative to the guide rail. The measuring device (5) encompasses a measuring rule (10) and a measuring head (21) that is provided with at least one sensor for scanning the measuring rule (10). The measuring rule extends in the longitudinal direction of the guide rail while being arranged along or on a surface (2.1) of the guide rail (2) facing the support zone (40) of the guide carriage (3). A cavity (25) for accommodating the measuring head is embodied in the guide carriage. Said cavity (25) is configured entirely or partly outside the support zone (40) while the measuring head (21) is disposed entirely or partly in the cavity (25) and entirely or partly outside the support zone (40).

摘要： A positioning device of a magnetic ruler is used to position the magnetic ruler onto a guideway, so as to prevent the magnetic ruler from being peeled off the guideway as a result of the reduction of the adhesiveness and to maintain the magnetic induction of the magnetic ruler. Moreover, the restriction assembly can also protect the magnetic ruler and keep it from dust.

摘要： An elastic fixture which is employed for attaching a length measuring apparatus to an object to be measured having a different linear expansion coefficient therefrom. The elastic fixture is elastically deformable in the lengthwise direction of the length measuring apparatus. The elastic fixture includes a sheet-metal curved beam having one end fixedly attached to the length measuring apparatus and the other end fixedly attached to the object to be measured. The sizes and the machining accuracy of the elastic fixture are less restricted, and the elastic fixture can be manufactured easily. In addition, the elastic fixture is applicable to relatively severe temperature environments in a manual machine tool or the like. Further, the sizes and the cost of the elastic fixture can be reduced as compared with a parallel spring mechanism.

摘要： The length measuring system comprises a scale member provided with a scale and a scanning unit, which is movable along the scale and is guided by the scale member or by separate tracks, which are parallel to the scale and is coupled to an actuating member by a backlashless coupling. The two coupling elements of the coupling cross each other and are in point contact with each other and having engaging surfaces which are centered on axes which are normal to the longitudinal direction of the scale member. A backlash of the coupling is prevented by a permanent magnetic biasing set, which comprises parts which are respectively connected to the actuating member and to the scanning unit and consist of two permanent magnets or of a permanent magnet and an armature.
