Patent number: 6619147Abstract: A linear actuator comprises a motor, a rotation-to-linear motion conversion mechanism having a screw and a nut, a support block supporting an end of the screw, and an actuator-side support member with a swing support mechanism (e.g., a swing axis or bearing portion in case of a Trunnion mechanism, or a swing support bearing portion or support leg of the swing support bearing portion). The actuator-side support member is part of the support block or an extension member of the support block or connected therewith. The swing axis of the swing support mechanism is located in the plane including the screw axis, and the force flow line inside the linear actuator is limited on the output shaft, the nut, the screw and the support block.Type: GrantFiled: October 26, 2000Date of Patent: September 16, 2003Assignee: Wittenstein GmbH & Co.

Patent number: 6460688Abstract: The aim of the invention is to provide a simple, safe to handle fixing device for a par that can be inserted between adjacent supports, especially centrally. Locating holes that are aligned approximately flush with each other, for holding elements of the part are provided in the adjacent supports. The holding elements are configured in the form of pegs mounted in the part. The pegs are provided with a screw thread at their second ends and each engage in a corresponding screw of sliding pieces that can slide in the part. The sliding pieces can be slid and stopped in a plane defined by the longitudinal axes of the pegs. The part has at least one pair of pegs on opposite outer surfaces that are flush with each other through the part.Type: GrantFiled: July 13, 2001Date of Patent: October 8, 2002Assignee: Wittenstein GmbH & Co.

Patent number: 6131479Abstract: A device for converting rotary motion into axial motion, having planetary rollers which are driven from a stationary drive housing by a drive shaft. These planetary rollers are held circumferentially at the same distance apart by a rotatable cage. The planetary rollers engage a thrust element via drive grooves on both the planetary rollers and the thrust element. The drive grooves on the planetary rollers do not engage the drive grooves on the drive shaft which frees the planetary rollers from harmful double engagement. The drive shaft drives these rollers via a gear tooth region on the rollers so as to function reliably and durably with a compact construction. The thrust element which is hollow, is therefore, able to move with a free thrust, i.e. without an additional guide element guiding it along a thrust path. Finally the thrust element has a high bucking strength so that it can withstand relatively large axial pressure.Type: GrantFiled: November 25, 1998Date of Patent: October 17, 2000Assignee: Dewitta Spezialmaschinenfabrik Wittenstein GmbH & Co. KGInventors: Michael Butsch, Roman Stauch
