摘要: A servo motor system having a direct drive motor, a controller, an encoder and a ball screw nut. The system may include a direct drive motor and a controller communicatively coupled to the direct drive motor and configured to provide a control signal to the direct drive motor to control rotational motion. The system may further include an encoder coupled to the direct drive motor and the controller and configured to provide a feedback signal to the controller indictive of the rotational motion of the direct drive motor. The system may further include a rotatably attached ball screw nut coupled to a housing for the direct drive motor, the ball screw nut configured to engage a ball screw shaft such that rotational motion imparted by the direct drive motor causes the servo motor system to move about the ball screw shaft while the ball screw shaft remains stationary.

摘要: A force transmission system as part of a surgical system which may be configured to be a minimally invasive and/or computer assisted surgical system. Operation of the system may be controlled by transmission of a force from a first section to a second section of the system. The first section and the second section may be separated by a partition or a barrier. The first section may be a non-sterile section and the second section may be a sterile section of the surgical system.

摘要: In a method for connecting a spindle to a spindle holding element in order to produce a longitudinal adjustment device for a vehicle seat, a spindle that extends along a longitudinal axis is connected to an attachment portion of a spindle holding element in a materially bonded manner using a resistance welding method. In this way, a method for connecting a spindle to a spindle holding element in order to produce a longitudinal adjustment device for a vehicle seat is provided, this allowing a firm connection of a spindle to a guide rail via one or more spindle holding elements, with a production process that is easy to manage and to monitor.

摘要: To provide an extension/contraction mechanism that can lessen increase stress imposed on belts. An extension/contraction mechanism according to the present disclosure includes a telescopic extension/contraction part, in which the extension/contraction mechanism includes a first drive source connected to a screw shaft in such a way that it can transmit a drive force, a first belt holder that accommodates a second belt in such a way that the second belt can be sent out to the screw shaft or the second belt can be wound-up from the screw shaft, a second belt holder that accommodates a first belt in such a way that the first belt can be wound-up from the screw shaft, and a first belt holder drive part and a second belt holder drive part. The first and second belt holder drive parts rotate the first and second belt holders independently of the rotation of the screw shaft, respectively.

摘要: A linear actuator arranged to convert rotary motion to linear motion. The linear actuator includes a linear shaft arrangement, having a first shaft portion and a second shaft portion and extends along a longitudinal axis (A) of the linear actuator. At least one of the first shaft portion and the second shaft portion of the linear shaft arrangement can be translated linearly along the longitudinal axis upon actuation. A first drive system has a first rotary component extending at least partially around the longitudinal axis. A second drive system has a second rotary component extending at least partially around the longitudinal axis at a different axial position to the first drive system. The linear actuator, when the first drive system fails, allows rotation of the second rotary component so that the second shaft portion moves relative to the first shaft portion.
