Abstract
The utility model belongs to a driving mechanism of electromechanical liquid, which relates to a double-cone disc type changing and driving mechanism of magnetic flow, which can simultaneously have rotating and shearing functions in opposite directions, and the shearing rate of magnetic-flow changing liquid is unchanged. The utility model is characterized in that the utility model is composed of six concentric discs such as left rotating disc groups 9 and 16, a left disc 14, right rotating disc groups 22 and 21, a right disc 25, etc. The same electrical machine and a gear reversing device are adopted, and the left and the right rotating discs 9 and 22 can be rotated in the opposite directions because of a left synchronous belt 6, a left synchronous pulley 8, a right synchronous belt 27 and a right synchronous pulley 23. Taper structures are all adopted by work planes of both faces of the left and the right discs 14 and 25 and the left rotating discs 9 and 16 and the right rotating discs 22 and 21 contacted with the changing liquid of magnetic flow, and thus not only areas of the work planes can be added and transferred torque is enhanced, but also the rotational inertia of each disc can be reduced, and the stiffness of each disc is enhanced. The utility model can be used as a high-performance electro-hydraulic servo device, a coupling, etc., and has better dynamic situation quality.
Description
The utility model belongs to a kind of mechanical electronic hydraulic driving mechanism.It has response rapidly, need not special characteristics such as interface between electronic control part and the machine power output, can be used as high performance electro-hydraulic servo control device, magnetic rheological clutch, coupling, break, damper etc.
The magnetorheological transmission device of existing disc type just provides the effect of the rotational shear on the single direction to magneto-rheological fluid, thereby can only adapt to the constant load of moving direction.In addition, the shear rate of magneto-rheological fluid is relevant with operating mode, so under identical extra electric field, the moment of torsion that mechanism transmitted is relevant with rotational speed.
The purpose of this utility model is to provide a kind of can have opposite direction rotational shear effect simultaneously, and the shearing moment of magnetic flow liquid and shearing rate are almost irrelevant; The utility model also is provided under the identical condition of disk diameter, the magnetorheological transmission device of double cone disc type that moment is big, disk rigidity is big that transmits than other magnetorheological transmission device, promptly the working surface that contacts with magnetic flow liquid of the two sides of left and right sides disk 14,25 and rotating disk 9,16,22,21 has all adopted tapered configuration.
According to concrete load request, (or between right-hand rotation dish group 22,21 and right disk 25) adds loaded magnetic field by iron core 15,18 and coil 19 between left-hand rotation dish group 9,16 that is full of magneto-rheological fluid and left disk 14 respectively, cause the magnetic rheology effect of magneto-rheological fluid, produce rotational shear stress, drive 14,25 rotations of two disks.Compare by the control signal of computer, constantly change the size of magnetic field M or the direction of rotational shear effect, make the sticky shearing moment of magneto-rheological fluid drive the torque that two disks 14,25 are exported, can adapt to unequally loaded and change load signal and input.
This mechanism is made up of six concentric discs such as left-hand rotation dish group 9 and 16, right-hand rotation dish group 22 and 21, left disk 14, right disks 25, left-hand rotation dish 9 and right-hand rotation dish 22 respectively by Bearing Installation on the right mandrel 26 of the left mandrel 7 of left disk 14 and right disk 25, two other rotating disk 16,21 is bound up by Cock screw and rotating disk 9,22.Left side disk 14 is connected into an integral body by coupling piece 12 by Cock screw with right mandrel 26 with left mandrel 7 and right disk 25, thereby realizes the mutual rotation of left and right sides disk 14,25 and left and right sides rotating disk group 9,16 and 22,21.Inject magneto-rheological fluid between left-hand rotation dish group 9,16 and the left disk 14 and between right-hand rotation dish group 22,21 and the right disk 25.Adopt same motor and gear wheel reversing device, be with 6 and left synchronous pulley 8 synchronously by a left side, the right side is with 27 and right synchronous pulley 23 synchronously, makes the left and right sides disc set can be in the opposite direction and be higher than the speed rotation of operating mode.By to being added to left-hand rotation dish group 9,16 and left disk 14, or be added to the control of the magnetic field control signal between right-hand rotation dish group 22,21 and the right disk 25, can make left disk 14 or right disk 25 produce forward and reverse and speed is higher than rotatablely moving of operating mode.Right mandrel 26 is by elastic coupling flexible coupling output torque.Because left-hand rotation dish group 9,16 and right-hand rotation dish group 22,21 are always with same rate counterrotating mutually, and in use, the speed of rotation that makes them is far above the input and output rotating speed, thereby the shear rate that the magnetic rheological body between left-hand rotation dish group 9,16 and left disk 14 and right-hand rotation dish group 22,21 and right disk 25 is subjected to is constant, realized that output torque and output speed are irrelevant, be convenient to the control of system.
The working surface that left and right sides disk 14,25 two sides and rotating disk 9,16,22,21 contact with magnetic flow liquid has all adopted tapered configuration, so not only can increase the working surface area, improve the moment of being transmitted, can also reduce the rotary inertia of each dish, the rigidity of raising dish, the dynamic quality of raising device.
