Abstract:
A rotational energy storage device (10) or spring which includes a roller-cam assembly having a shaft (14), a ring (12) rotatably disposed about the shaft, and at least one roller (16) disposed between shaft and ring. The roller (16) is configured such that, upon rotating the ring relative to the shaft, the roller interferes with the ring and the shaft to convert and effect storage of mechanical energy created by the relative rotation of the ring and the shaft. Preferably a plurality of spaced rollers are positioned between ring and shaft. A cam geometry (20) which is symmetrical or asymmetrical is provided on the shaft, the ring, the roller, and combinations thereof. A rotational energy storage device having a back-up ring with alternating thin and thick cross-sectional areas is further provided which is indexed to provide regions of low and high stiffness regions against each roller.
Abstract:
A cardan joint (1), whose input end is connected to the transmission (2) and whose output end is free or connected to a defined inertia weight (6). Said joint is mounted in a holding fixture (8) serving as output shaft (3) in such a way that its buckling angle beta is continuously variable. The Figure shows a possible way to transmit torques and energies with almost no friction loss. Inertia weights (6) in the shaft end serve to store energy and enable lossfree transmission taking into account conservation principles. Spring elements can be used instead of inertia masses. Counterweights (7) compensate for the influence of centrifugal force.
Abstract:
Actuators (96) for power driven accessories for moving objects, such as vehicle power windows, windshield wipers, vehicle power antennas, power side view mirrors (86), catheter drivers, curtain moving machines, bi-directional rotary motors, thruster mechanisms that move relative to a reaction surface or that drive a driven member relative to itself, use orthogonal oscillatory transducers cooperatively to drive intermediary elements to move these objects bi-directionally along constrained paths. The actuators may also power a pneumatically driven autonomous robot element using dual pneumatic DSES elements such as planar contact surfaces with an array of apertures which are cyclically switched from a source of compressed air which acts as a lubricant to greatly reduce surface friction to a vacuum source, which acts as a clamping medium increasing contact frictional force. Orthogonal bladders are cyclically pressurized or vented to move a central block relative to a surrounding frame. All cyclic activity is oscillated at the same frequency. Coordination of phase differences relative to the DSES cycles determines the path of the robotic element which can vector anywhere on a smooth planar surface.
Abstract:
Eine Handwerkzeugmaschine hat einen Motor, eine Werkzeugaufnahme und ein Schlagwerk, das in einen Antriebsstrang zwischen Motor und Werkzeugaufnahme geschaltet ist. Das Schlagwerk beinhaltet eine erste Welle (12) und eine zweite Welle (13). Ein magnetisch leitfähiges Hohlrad (15) ist mit der ersten Welle (12) verbunden. Eine Innenwand (32) des Hohlrads (15) ist bezüglich einer Achse (14) der zweiten Welle (13) nicht rotationssymmetrisch. Ein magnetisch leitfähiges Flügelrad (16), ist mit der zweiten Welle verbunden und das Flügelrad ist innerhalb des Hohlrads (15) drehbar angeordnet. Das Flügelrad (16) ist in einer ersten Stellung um einen ersten Luftspalt zu dem Hohlrad (15) beabstandet und in einer zweiten Stellung um einen zweiten Luftspalt zu dem Hohlrad (15) beabstandet, wobei der erste Luftspalt kleiner als der zweite Luftspalt ist. Die fehlende Rotationssymmetrie sowohl der Innenwand und des Flügelrads bedingen die unterschiedlichen Stellungen. Eine Magnetanordnung (23) ist koaxial zu der zweiten Welle (13) angeordnet. Eine magneto-rheologische Flüssigkeit füllt einen Hohlraum zwischen dem Hohlrad (15) und dem Flügelrad (16) aus.
Abstract:
According to the invention, the first end (2a) and the second end (2b) of the pre-tensioned spring (2) are positioned in their pre-tensioned states against a first stop (1a) and a second stop respectively (1b). The rotating body (1) is first rotated at least X times about its longitudinal axis, without the action of external forces, whereby the first end (2a) engages once in a cam wheel (3) during each rotation, said wheel having at least X + 1 teeth (3b) and at least one cam (3a) that runs parallel with the teeth (3b). The cam wheel (3) thus rotates one tooth (3b) further with each rotation of the rotating body (1). After at least X continuous rotations, the rotating body (1) is subsequently subjected to pre-tensioning until the cam wheel (3) and its cam (3a) lies against a third stop (6) and the first end (2a) simultaneously engages in the cam wheel (3). The rotation is then continued in order to increase the torque, whereby the first end (2a) remains engaged in the cam wheel (3) and is released from its position against the first stop (1a). The invention also relates to the use of said method in an actuating drive for setting the valve stroke of a motor vehicle.
Abstract:
A toroidal piston engine has a pair of impact rings that transfer kinetic energy between rotors, and are modified to reduce stresses during collisions. Generally, each impact ring has a pad, and is coupled to a rotor such that when a rotor rotates, the pad of one impact ring strikes the pad of another impact ring, transferring kinetic energy between the rotors, while preventing pistons coupled to the rotors from striking one another directly.
