A bottom door opening-closing mechanism includes a first connecting rod, a second connecting rod, a swing rod, a bottom door opening-closing drive cylinder and a transmission shaft. The swing rod is hinged to the second connecting rod and the piston rod of the bottom door opening-closing drive cylinder. One end of the first connecting rod is hinged to the second connecting rod, and the transmission shaft is connected to the second connecting rod. The cylinder body of the bottom door opening-closing drive cylinder is fixedly connected with a first locking hook, and the swing rod is fixedly connected with a second locking hook which can be caught by the first locking hook. A bottom door device and a drop-bottom hopper car are further provided. In the present invention, the first locking hook and the second locking hook are caught with each other to achieve a secondary locking. Such an arrangement has some advantages such as a simple structure and low manufacture and maintenance costs. Further, a secondary locking may be achieved while closing the bottom door only by controlling the bottom door opening-closing drive cylinder, so that the complexity of the control system is reduced.

A rotary actuation mechanism is disclosed. The rotary actuation mechanism can include an actuator having a body, and a slider movable on a linear path relative to the body. A first linkage can be pivotally coupled to the body at a first pivot having a first axis. A second linkage can be pivotally coupled to the slider at a second pivot having a second axis, and pivotally coupled to the first linkage at a third pivot. A length of the first linkage between the first pivot and the third pivot can be equal to a length of the second linkage between the second pivot and the third pivot. The slider can be movable to position the second axis in a collinear relationship with the first axis. The rotary actuation mechanism can include an anti-singularity device to constrain movement of the body when the first axis and the second axis are in the collinear relationship.

An active bearing at least for vibration reduction is described, comprisinga) an interface (7) to be fitted to a load (8);b) at least one support element (3) in an operative connection with the interface (7) and a support unit (6);c) at least one linear actuator (5) supported indirectly or directly on the support unit (6);d) a gear unit (4) for the path transmission of an actuating path change originating from the linear actuator (5), said gear unit being in an operative connection with the at least one linear reactor (5);e) at least one decoupling unit (1), which serves for the decoupling of the static load transfer and for transmitting the dynamic load transfer; wherein the at least one linear actuator (5), the gear unit (4) and the at least one decoupling unit (1) are disposed serially.
摘要:
A motion conversion system is described. The motion conversion system comprises a first torsional member operative for rotating in a first direction. A second torsional member is offset a distance from the first torsional member, wherein the second torsional member is operative for rotating in a direction opposite from the first direction. And, a lateral member has a lower surface connected to the first and second torsional members. Wherein, translational movement of the lateral member results from rotational movement of the first and second torsional members.
