摘要： PROBLEM TO BE SOLVED: To provide a clutch wherein an overload prevention device is disposed adjacently to a collision point without limiting a coasting distance after occurrence of collision, and treatment, reuse after answering, and detection of operating state of the overload prevention device are easily performed.
SOLUTION: The overload prevention device for spindle nut comprises: a spindle nut 2 disposed within a clutch case 5 disposed on and engaged with a ball screw type spindle 1 and fixed to a reciprocating table so as to be rotatable to a shaft 3 of the spindle and fixed in the axial direction; and a molded body 7 disposed between the spindle nut and the clutch case 5. Torque transmitting coupling between a recessed part 8 of a pressure flange and a recessed part 9 of a case is performed by the molded body 7 without play to thereby prevent an overload.

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 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.

摘要： The invention relates to a method for preventive function control in an electromagnetic spring pressure brake for a simpler and more accurate determination of the critical operating state. The spring pressure brake comprises at least one coil, and an armature disk, a coil carrier having compression springs distributed thereon, a control module, and a monitoring module having at least one semiconductor component, a current measuring device, and a voltage measuring device, wherein the method comprises the following steps: Initially, the spring pressure brake is controlled by the control module by means of a voltage. Next, the state variables current (I) and voltage (U) at the electromagnetic spring pressure brake are measured by the monitoring module. Subsequently, a determination variable (T; F) of the electromagnetic spring pressure brake is determined by the monitoring module. Said determination variable (T; F) is summed over a range (a), which extends from the starting point of the actuation to a point (W), at which the armature disk begins to move. At the point (W), a current value is detected, at which the movement of the armature disk begins. The determination variable (T; F) is additionally summed over a range (b), which extends from the point of actuation, when the current (I) again reaches the value detected above, up to the point, at which a constant current is reached. Subsequently, a ratio (X) is calculated from the sum of the determination variable over the range (a) to the sum of the determination variable over the ranges (a) and (b). Upon reaching or exceeding a predetermined value (Y) by the value of the ratio (X), a state signal relating to the spring pressure brake is output.

摘要： A disengaging overload clutch, having a clutch hub and a pressure flange mounted rotatably and in which transmission bodies are held in the recesses of the pressure flange by way of the force of spring elements and transmit the torque from the pressure flange to the clutch hub. During overload between the clutch hub and the pressure flange, the clutch moves in—a first rotational direction into a disengaged state, wherein the relatching takes place by rotation between the clutch hub and the pressure flange in a second opposite rotational direction; or more precisely by the interaction between the control pins, control cams which are connected to the clutch hub, and control grooves with groove flanks. The control pins are fitted with pin magnets, which are pressed away from control magnets of identical polarity, in order to bring the control pins into engagement with the control cams and the control grooves.
