摘要： Disconnecting overload clutch, comprising a hub (5) which has axially directed hub recesses (4) arranged on the periphery thereof, a pressure flange (1) mounted on the hub (5) in a rotatable manner with axially directed pressure flange depressions (2), wherein in each hub recess (4), for example, two rotationally symmetrical transmission bodies (3,9) are arranged, which are pressed into the pressure flange depressions (2) by spring elements (6) via a switch element (7). According to the invention, the switch element (7) has axially projecting switch element cams (8) facing the front-end exposed surface (21) thereof, which in the engaged state transfer the force of the spring elements (6)to the transmission bodies (3,9) and thus axially engage with the hub recesses (4). When disengaging, the switch element (7) experiences an axial displacement and rotary movement with the switch element cams (8) in relation to the hub (5), so that the switch element cams (8) are transferred into a position wherein same transfer the force of the spring elements (6) only onto a support surface (20) of the hub (5) with the result that the clutch can freely come to a stop.

摘要： A compact control device for failsafely controlling an electrical actuator capable of moving a movable machine part into a defined end position, has an input connection for receiving an external control signal representing a desired position of the machine part. The compact control device further has an input part for detecting a position signal, which signals an actual position of the machine part at the defined end position. A power section comprises a power switching element for switching on and failsafely switching off a control current for the actuator that is supplied to the electrical actuator via a first output connection. The compact control device has a second output connection for providing an external status signal and an evaluation unit which actuates the power switching element depending on the external control signal and generates the external status signal at the second output connection depending on the position signal.

摘要： An electromagnetically switchable brake, preferably spring-loaded brake, comprising at least one coil carrier (3) and at least one armature plate (1), wherein the axial distance of the coil carrier and armature plate relative to out another is variable, comprising at least one rotor (7) or at least one hub of a shaft to be braked, and comprising damping members arranged between the armature plate (1) and coil carrier (3), between the end faces of the coil carrier (3) and armature plate (1) which face one another. It is considered to be novel and inventive that the solid body of coil carrier (3) and/or armature plate (1) has an integral damper structure (D), which is composed of an least one elastic tab (12) and a foot (13), the elastic tab (12) being an integral part of the solid body of the armature plate (1) or of the coil carrier (3) (FIG. 1.1).

摘要： Preventative function control in electromagnetic spring pressure brakes is disclosed. Initially, the spring pressure brake is controlled by voltage. Next, state variables current and voltage are measured. Subsequently, a determination variable is determined and summed over a first range, which extends from a starting point of actuation to a point at which an armature disk begins to move. At the point, current value is detected at which movement of the armature disk begins. The determination variable is summed over a second range, which extends from the starting point, when the current reaches the value detected above, up to a constant current. Subsequently, a ratio is calculated from the sum of the determination variable over the range to the sum of the determination variable over the first and second ranges. Upon reaching a predetermined value by the value of the ratio, a state signal is output.

摘要： A method for controlling an electromagnetic brake (1) having a coil carrier (2), a solenoid (5), an armature disc (7), and at least one further force-exerting element. The internal and external poles (3, 4) of the coil carrier each have a front surface with a varying gradient that fits, in a complementary fashion, the front surfaces of the respective internal and external poles (8, 9) of the armature disc. The brake has an air gap (11) which varies in size and forms a stroke region (21). When excitation occurs, the solenoid generates a magnetic force, and the force-exerting element generates an opposing force, wherein the ratio of the solenoid's magnetic force and the opposing force varies at least once between greater than and smaller than one during the movement of the armature disc in the stroke region owing to the variation of the excitation of the solenoid.
