摘要： Revolving rollers, each provided on an outer peripheral surface thereof with revolving roller grooves extending therearound, are caused to mesh with a rack rod thread of a central rack rod with an axial angle over a lead angle of the rack rod thread and arranged for rotation on a holder member to be twisted. The holder member is rotated round the rack rod by a motor to translate the rack rod. A large thrust can be generated while ensuring a high reliability since a high efficiency is achieved by realizing rolling contact in set points of mesh of the rack rod thread and the revolving roller grooves, points of mesh are made planar, and interference in other points than the points of mesh can be suppressed. Also, play can be restricted by assembling the revolving rollers to the rack rod thread while applying torque in a direction, in which the axial angle is increased.

摘要： An actuator including a threaded shaft and a carriage having a shaft engaging portion coupled to the threaded shaft. The carriage is moveable in a direction parallel to an axis of the threaded shaft upon a relative rotation between the threaded shaft and the shaft engaging portion. A ceramic bushing is coupled to the shaft engaging portion of the carriage, the bushing surrounding the threaded shaft. The ceramic bushing is much harder than heretofore used materials and results in greatly reduced particulate formation. The carriage or portion thereof can be formed around the bushing, e.g., by injection molding.

摘要： A leadscrew mechanical drive includes a leadscrew having a leadscrew axis and a leadscrew thread with a nonzero leadscrew thread pitch. A leadscrew follower structure preferably having two leadscrew followers is engaged to the leadscrew. Each leadscrew follower includes a threaded insert having an insert thread with a nonzero insert thread pitch different front the leadscrew thread pitch. The insert thread is engaged to the leadscrew thread over a circumferential distance of less than one-half turn of the insert thread. Each leadscrew follower further includes a bearing in which the threaded insert is received and which permits the threaded insert to rotate about an insert axis that is inclined to the leadscrew axis by an angle θ for the first leadscrew follower and −θ for the second leadscrew follower, and a bearing support in which the bearing is received. A preload structure biases each of the leadscrew followers against the leadscrew.

摘要： The present invention consists of a connection, having an anchored, elongated tension member, a fastening member attached to the elongated tension member, a resisting member that receives the elongated tension member and an expansion device that receives the elongated tension member there through and is compressively loaded between the fastening member and the resisting member by operation of the fastening member on the elongated tension member. The expansion device is formed with a sleeve. First and second bearing members are received in the central aperture of the surrounding sleeve and operatively connected to the surrounding sleeve. At least one of the bearing members is threadably connected to the sleeve. This bearing member can rotate in relation to the surrounding sleeve. A torsion spring connects the first and second bearing members and is located within the surrounding sleeve. The torsion spring biases the first and second members in opposite rotational directions such that at least one of the bearing members is forced to rotate along the thread of the surrounding sleeve away from the other bearing member and out of the surrounding sleeve.

摘要： An assembly including a base and first and second spaced-apart shafts secured to the base and extending generally perpendicular to an elongated aperture of the base. A carrier includes a first support member slidingly receiving the first shaft, a second support member receiving the second shaft, and an elongated opening extending between the support members and generally perpendicular to the shafts. The elongated opening of the carrier is for aligning with the aperture of the base and an elongated slit of a collimator supported on the carrier for passage of an x-ray beam therethrough. A backlash-resistant nut assembly is threadingly received on a threaded portion of the second shaft and secured to the second support member.

摘要： A screw drive with rolling elements, optionally a ball screw drive, includes a screw spindle with a spindle axis and a double nut running on the screw spindle, with two separately formed single nuts which are substantially rigidly joined in the direction of the axis of the spindle. In order to set a desired play or bias relative to the screw spindle, the two single nuts can be turned continuously about the axis of the spindle relative to each other and fixed in any relative rotary position corresponding to the desired play or bias. According to the invention, a first of the two single nuts or an intermediate element joined thereto and arranged between the two single nuts has at least one peripheral section pressed into an associated aperture in one of the single nuts. In one embodiment, the intermediate element is an annular disk that is arranged orthogonally to the spindle axis.
