Patent number: 11878382Abstract: A rotary indexing table assembly includes an axis of rotation, a rotation element and a receiving assembly. The rotation element is rotatable about the axis of rotation and has a centering opening coaxial with the axis of rotation. The receiving assembly has a spring system and a pin assembly. The pin assembly has a pin body, movable along the axis of rotation by the spring system and settable in a set-up state or a blocking state. In the set-up state, the rotation element is releasably connected to the receiving assembly, and in the blocking state, the rotation element is fixedly connected to the receiving assembly.Type: GrantFiled: September 29, 2020Date of Patent: January 23, 2024Assignee: Schaeffler Technologies AG & Co. KGInventor: Wolfgang Volk

Patent number: 11858124Abstract: A quick-change system includes a first exchange tool designed as gripper jaws, a second exchange tool, a first receiving part, and a ball catch. The first receiving part includes a first receiving opening for receiving a one of the first exchange tool or the second exchange tool. The ball catch is for temporarily fixing the one of the first exchange tool or the second exchange tool on the first receiving part. The ball catch includes a sleeve that is closed on one side and a spring-mounted press ball arranged in the sleeve. The one of the first exchange tool or the second exchange tool has a ball-receiving opening, and the press ball can be manually engaged and disengaged in the ball-receiving opening.Type: GrantFiled: June 23, 2020Date of Patent: January 2, 2024Assignee: Schaeffler Technologies AG & Co. KGInventor: Wolfgang Volk

Publication number: 20230415494Abstract: A device for marking a component. The device includes a laser device for generating a laser marking beam, a support surface for providing the component to be marked, and a housing for housing a working region between the laser device and the component to be marked. The housing has a multi-part design, and the housing includes at least a first housing part and a second housing part. The two housing parts are designed to be movable relative to each other and are arranged such that in a loading position, the housing provides an open working region, by means of which the component to be marked can be introduced into the working region, and in a working position, the housing completely closes the working region.Type: ApplicationFiled: October 4, 2021Publication date: December 28, 2023Applicant: Schaeffler Technologies AG & Co.

Patent number: 11754129Abstract: A method for installing a wrap spring includes providing a first sleeve with a first longitudinal axis extending in an axial direction and a lateral surface, and the wrap spring designed to frictionally abut the lateral surface. The wrap spring includes a nominal diameter and a central axis. The method includes applying the wrap spring in a relaxed state to the lateral surface at an angle ? between the central axis and the first longitudinal axis, elastically twisting the wrap spring to change the nominal diameter while the wrap spring contacts the lateral surface, reducing the angle ?, threading the wrap spring onto the first sleeve, and relaxing the wrap spring to establish frictional contact with the lateral surface.Type: GrantFiled: February 13, 2020Date of Patent: September 12, 2023Assignee: Schaeffler Technologies AG & Co. KGInventor: Wolfgang Volk

Publication number: 20230053613Abstract: A handling device for transferring workpieces includes a workpiece carrier arranged to receive workpieces and a rotatable workpiece-conveying apparatus arranged to receive the workpieces from the workpiece carrier in a first angular position and to transfer the workpieces to a storage station in a second angular position. The workpiece-conveying apparatus includes an axis of rotation, a first linearly displaceable feed element and a second linearly displaceable feed element, intersecting the first feed element at the axis of rotation and simultaneously actuatable with the first feed element. The apparatus also includes first and second non-rotatable linear actuators. The first and second feed elements have end pieces, each arranged for direct interaction with the workpiece and a respective linear actuator. The feed elements may intersect at an angle of 90°. The first feed element may have a straight shape and the second feed element may have an offset shape.Type: ApplicationFiled: February 5, 2021Publication date: February 23, 2023Applicant: Schaeffler Technologies AG & Co.

Publication number: 20220234118Abstract: A quick-change system includes an exchange tool with a ball receiving opening, a receiving part with a receiving opening for receiving the exchange tool, and a ball catch for temporarily fixing the exchange tool on the receiving part. The ball catch includes a sleeve that is closed on one side and a spring-mounted press-ball arranged in the sleeve for manually engaging and disengaging with the ball-receiving opening. In an example embodiment, the sleeve has an axis of symmetry, the spring-mounted press-ball is movable along the axis of symmetry, and the ball-receiving opening has a central axis extending parallel to the axis of symmetry when the receiving part is engaged with the exchange tool.Type: ApplicationFiled: June 19, 2020Publication date: July 28, 2022Applicant: Schaeffler Technologies AG & Co.
