| 20100206104 | LINEAR MOTION DEVICE WITH COMPACT MOTOR ARRANGEMENT - A linear motion device has a first assembly and a second assembly which is linearly movable relative to the first assembly; a row of rolling elements that may circulate endlessly is located between the first and second assemblies, the first assembly including a rotatable threaded spindle that extends parallel to the longitudinal direction, and that is engaged in a screw-type manner with a threaded nut, the threaded nut being a component of the second assembly; the first assembly also includes an electric motor that is connected to the threaded spindle in a rotationally driving manner, and the rotational axis of which extends parallel to the threaded spindle; the first assembly includes a single-pieced, first body. The threaded spindle and the electric motor are located next to one another in the region of the first body, the electric motor extending along a first longitudinal section of the first body, while a first rolling surface for the rolling elements extends across a second longitudinal section—which differs from the first longitudinal section—of the first body; the threaded spindle extends over the first longitudinal section and at least in sections over the second longitudinal section of the first body, and the rolling elements are capable of circulating endlessly in the first assembly. | 08-19-2010 |
| 20100206113 | LINEAR MOTION DEVICE WITH PARTIALLY SUPPORTED ROLLING SURFACE PART - A linear motion device has a first assembly and a second assembly, at least one first rolling surface that extends in a longitudinal direction and provided on the first assembly, the first rolling surface being located opposite a second rolling surface which is provided on the second assembly, a row of rolling elements that circulate endlessly in the first assembly is located between the first and second rolling surfaces, and at least one central longitudinal section of the first rolling surface is designed such that the rolling elements are at least partially relieved of the load. The first rolling surface is provided on a separate first rolling surface part in the form of a profiled element having a substantially constant cross-sectional shape, the first rolling surface part is situated in a central longitudinal section at a distance from a first body of the first assembly, and is supported on the first body on both sides in the longitudinal direction next to the central longitudinal section. | 08-19-2010 |
| 20100209027 | LINEAR MOTION DEVICE COMPRISING A DEFLECTION ASSEMBLY HAVING A SINGLE DEFLECTION PASSAGE - A linear motion device has a first assembly and a second assembly which is linearly movable relative to the first assembly, in which at least one first rolling surface which extends in a longitudinal direction is provided on the first assembly, the first rolling surface being located opposite a second rolling surface provided on the second assembly, and in which a row of rolling elements is located between the first and second rolling surfaces, and in which a return passage that is substantially parallel to the first rolling surface is provided in the first assembly, the return passage being connected at either end via a curved deflection passage to the first rolling surface such that rolling elements are transferred, thereby enabling the rolling elements to circulate endlessly, and in which the first assembly includes at least one deflection assembly that may be installed as a whole, and that includes a single deflection passage, and the return passage is provided directly and completely in a separate first body of the first assembly, and the deflection assembly is fastened to the first body via a single, separate fastening bolt that is installable from one side, the fastening bolt being located in the region of the center of curvature of the assigned, curved deflection passage. | 08-19-2010 |
| 20100209028 | LINEAR MOTION DEVICE COMPRISING PROJECTION-FREE RETURN PASSAGE - A linear motion device has a first assembly and a second assembly which is linearly movable relative to the first assembly, in which at least one, and preferably at least two, first rolling surface(s) which extend(s) in a longitudinal direction is/are provided on the first assembly, each first rolling surface being located opposite a second rolling surface provided on the second assembly, and in which a row of rolling elements is located between the first and second rolling surfaces, and in which the first assembly includes a single-pieced, first body and at least one return assembly, at least one return passage being provided in the first body, and furthermore in which at least one curved deflection passage is located entirely within the deflection assembly and connects the first rolling surface to the return passage in a manner such that the rolling elements may circulate endlessly, and in which at least one projection that engages in the return passage is provided on the deflection assembly. The projection is formed by a flexible tube that limits a flexible passage for the rolling elements, the flexible passage connecting the deflection passage to the return passage. | 08-19-2010 |
