A joint assembly between a first component and a second component comprises a ball portion configured to be connected to the first component. A socket is configured to be connected to the second component or ground and comprises a socket base, a socket cover, and a spherical joint cavity within the assembled socket base and socket cover to receive the ball portion to form a spherical joint. At least one biasing member is in the joint assembly. A clamp clamps the socket base to the socket cover such that the at least one biasing member biases the socket base and the socket cover toward one another.

Joint assembly for motion simulator

A linear actuator comprises a motor for producing a bi-directional rotational output. A casing is connected to the motor at a proximal end, the casing having an inner cavity defining a joint surface. A threaded shaft is within the inner cavity of the casing and actuated by the motor for rotation. A sliding tube assembly has a sliding tube in sliding arrangement with the inner cavity of the casing for moving in translation in an axial direction relative to the casing. A pair of traveling nuts is connected to the sliding tube assembly for moving with the sliding tube in the axial direction, the traveling nuts being operatively engaged to the threaded shaft for converting a rotational motion of the threaded shaft into a translation of the sliding tube, the traveling nuts being on opposite sides of a member of the sliding tube assembly connecting the traveling nuts to the sliding tube.

Linear actuator for motion simulator

A linear actuator comprises a motor having an output. An end block is connected to a casing and to the motor and has a counterbore at a distal end with a bearing seated and retained in the counterbore. A coupling assembly couples the output shaft of the motor to a threaded shaft for transmission of the rotational output to the threaded shaft. A sliding tube is in sliding arrangement with the inner cavity of the casing for moving in translation relative to the casing.

A linear actuator comprises a motor having an output shaft. A casing of the motor has an inner cavity with a counterbore seat surface. A threaded shaft is within the inner cavity. A bearing is received in the counterbore seat surface. A coupling assembly has a first coupling component receiving the rotational output from the motor, and a second coupling component coupled to the first coupling component for transmission of the rotational output to the threaded shaft. A sliding tube is sliding arrangement with the casing for moving in translation relative to the casing. A traveling nut is in the sliding tube for moving therewith for converting a rotational motion of the threaded shaft into a translation of the sliding tube. An integral driven assembly unit comprising the bearing, the threaded shaft, the traveling nut and the sliding tube interconnected to one another so as to be removable by pulling out the integral driven assembly as a whole from the inner cavity of the casing via the proximal end.

A coupling assembly couples the output shaft to the threaded shaft, and has a first coupling component receiving the rotational output from the motor, and a second coupling component coupled to the first coupling component for transmission of the rotational output to the threaded shaft. A substantial portion of a coupling is in an axial section of the linear actuator delimited by a proximal and distal surface of the bearing. A sliding tube is within the inner cavity and translates relative to the casing. A traveling nut is connected to the sliding tube for moving therewith for converting a rotational motion of the threaded shaft into a translation of the sliding tube.
