Usage: industrial robotics, mainly for actuators degrees of freedom anthromorphic robots, as well as all areas requiring the use of the progressive movement. The actuator includes an active element made in the form of two twisted between the insulated conductors, one ends of which are connected with the source of electrical energy, and other connected and associated with the output shaft. The actuator is further provided with C-shaped magnetic cores arranged in a row in the same plane, and additional spiral-spatial conductive element. The coils of the additional spiral-spatial element are located in the ends of the C-shaped cores. Each layer of the main element connected with stretch marks with housing and output shaft attached to an extreme turn the main element. The technical result is to reduce size. 2 Il.
The invention relates to electromechanics, and more specifically to an electrodynamic elements, designed for converting electrical energy into mechanical energy. Such actuators can be used in robotics, mainly in and the Central-dimensional electrodynamic element, containing a movable part in the form of two flexible insulated conductors, one ends of which are fixed on the base, while others are connected and placed on a movable plate, while the flexible insulated conductors are twisted, and their ends are connected to power sources [1].
The disadvantage of the element is the possibility of realization of a predominantly rotational motion. This disadvantage is eliminated in an electrodynamic actuator [2] , which is provided with an additional conductive loops formed together with the main loop two groups of coils arranged against each other, as well as additional clip, two rods mounted on these hoops, and studs at the ends of the coils of each group are mounted on the respective holder, and the other of their ends located opposite each other, are interconnected by a rod.
The disadvantage of this device is the complexity of the structural design, which is caused by the necessity of strict observance of the linear size of the spiral to ensure uniform load.
Closest to the claimed combination of essential features for a linear actuator movement, equipped with an additional the figures corresponding to the primary active element, connected in parallel and connected with the casing and with the other end of the additional spiral spring, and two annular chambers with a filling of elastic material, one of which is located in the housing, and the other on the rod, while the fillers cameras have the possibility of contact with the corresponding surfaces of the additional and main active elements [3].
The disadvantage of this drive is its low weight and dimensions, which are caused purely Electromechanical effect, while with increasing distance between the turns of the loop, the effective force is reduced in times square, which in combination with high current loads worsen the performance of the device.
The invention is directed to an increase in the effort.
This is achieved by the fact that the actuator is further provided with C-shaped magnetic cores arranged in a row in the same plane, and additional spiral-spatial conductive element coils which consistently cover the ends of the C-shaped core, the exciting magnetic field in them, providing the alternation of their polarity and turns of the primary spiral spatial element are located in the area of torso is by using stretch with the body, and the output shaft is attached to the extreme primary coil spiral spatial element.
The achievement of the technical result is an increase in the effort - due to the fact that, in addition to the electrodynamic efforts to turn the main element, there is an additional tensile force due to interaction of the primary coil with the magnetic field of the magnetic circuit, which in turn is caused by the action of an additional element.
The invention is illustrated in the drawing, where Fig.1 shows an actuator linear displacement, end view of the magnetic circuit of Fig.2 shows a section of the actuator in a vertical plane in the middle of the magnetic circuit.
Actuator linear displacement includes a housing 1, an output shaft 2 connected mechanically at round 3 of the main spiral spatial element 4. There is also an additional spiral-spatial element 5, covering the ends 6 of the C-shaped magnetic circuit 7. Conclusions conductive spirals connected to the lead block 8 that is installed on the housing 1. The unit is attached strap 9, which by means of straps 10 and bolts 11 are installed With obraznic the cores in a row in the same plane. There are also stretching the spiral spatial element 5 is an element of excitement, which provides the direction of the field on the C-shaped magnetic core and may present a closing part (the body). Thus there is an alternation of polarities of all the ends 6, located in a C-shaped magnetic circuits. In the field these ends of the coils are spiral-spatial element, which arise lateral force directed from the ends to the periphery. Folding diamond-shaped power circuit provides the moving rod 2 up. In this working position of the main element shown in Fig.1 by the dotted line. Stretching 12 serve to guarantee the spatial orientation of the coils of the primary spiral spatial element. Additional spiral-spatial element 5 plays the role of a winding of a magnetic field in the C-shaped manageprofile. It is important to note that the coils of the primary spiral spatial element 4 are located in the ends 6 of the C-shaped cores, because this arrangement provides high-quality functioning of the device. Moving extreme wrap, and hence the rod 2, the length of the elements may not exceed the value of the pole division.
The introduction of additional spiral spaces within the square end. The resulting Electromechanical efforts are large in absolute value than a purely electrodynamic efforts that would arise in the coils of the main element in the absence of additional, because there is an increasing field caused by the presence of ferromagnetic masses.
