摘要： A mechanism for transforming a rotational movement into a linear movement, comprising a non-deformable nut, that is prevented from rotating but not from axially moving, a radially deformable tubular screw, having freedom of rotation but not of axial movement and having a pitch equal to that of the nut but of a slightly external smaller diameter than the internal diameter of the nut. A pushing device inside the screw, with the ability to rotate and to push against the internal wall surface of the screw at least at three circumferentially equidistant points so as to radially deform the screw wall outwards, until bringing the screw wall to rest against and screw into the nut at an equal number of points. The pushing device may be constituted of independent rolling elements like rolling bearings on a core on a support or may be a cam in contact with the screw or through rolling elements.

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： A displacement unit for at least one element to be displaced is provided comprising a drive unit, a transfer element that is caused to move by the drive unit and that comprises a thread or a tooth set, and an engagement element, which engages into the thread or tooth set of the transfer element and is thus driven by the motion of the transfer element, and by whose motion the displaced element is moved. The engagement element is configured elastically, in such a way that it deforms elastically upon contact by the displaced element against a stop or obstacle.

摘要： An anti-backlash nut is assembled on a reinforced lead screw for bilateral motion lengthwise of the lead screw as the screw is rotated. A hollow, elongate reinforcing rail extends lengthwise of and surrounds the lead screw. A slot in the rail extends lengthwise of the central axis of the lead screw. The anti-backlash nut comprises two separate portions, each portion having a tongue which extends radially through the slot and has threads engageable with the threads of the lead screw for moving both nut portions in reciprocating motion lengthwise of the rail when the screw is rotated. Spring means are employed for forcing the nut portions apart to urge the flanges of their threads into forcible engagement with the threads of the lead screw to prevent backlash, while the anti-backlash nut translates laterally along the reinforcing rail.

摘要： A device for coupling a rotary member to an axially movable input stem of a linear displacement transducer comprises an axially movable element which is coupled to the stem and threadedly engages the rotary member. The axially movable element is restrained against rotation by spring loaded detents and has abutments which can engage a lug on the member when the element reaches its limiting axial positions. This engagement causes the element to be rotated with the member and input to the transducer is arrested.

摘要： An actuator for use in or with a glassware forming machine for driving a member through an arcuate path, such member being a pusher cylinder for moving glassware articles. The pusher member comprises a linearly movable piston for linearly moving a convoluted shaft attached thereto. The convoluted shaft has three surfaces thereon which act as tracks for three roller bearings mounted on a hub which is disposed about the shaft. Linear motion of the shaft is converted into rotary motion in the hub by the action of the bearings running on the convoluted sides of the linearly moving shaft.

摘要： The base portion of the wiper contact is deformable to assure continuous electrical connection between a lead screw and the aligned resistive strip located on the surface of the turret, as the contact is inserted therebetween. The strip engaging portion is located on the resilient base portion approximately midway between the guide portion and thread engaging portion such that the deformation causes the contact to exert substantially balanced forces on the lead screw. The structure of the guide portion of the contact is designed to enhance mechanical stability by preventing dislodgement of the contact without the necessity for cooperation with other external parts which obstruct visibility of the position indicating member, which is mounted on the contact and extends over the entire width thereof. In addition, means are provided to prevent the relative lateral movement between the contact and the lead screw during lead screw "runoff".
