MARTENSITE DRIVE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: in multisectional martensite drive each of the sections is provided with spring drive 9 and 10 and with a few pairs of movable supports 11 between which temperature- sensing actuating members 6 are located. The actuating members are hinged to the movable supports, thus forming actuating modules 12. One of the extreme actuating modules rests against drive 9 and 10. The hinged joint between temperature-sensing actuating member 6 and movable support 11 is in the form of asymmetrical bushing provided with slot for fixing the end of the temperature-sensing actuating member and with through hole for receiving axle fixed on movable support 11. The movable support consists of the pair of disks which are rigidly coupled with each other and provided with rectangular-shape cutouts around the edge of the disk. The disk is provided with semi-round cross section radial bore which serves for facilitating mounting of the ring serving as the axle for the asymmetrical bushing. The through whole of the asymmetrical bushing carries cylindrical insulator. Movable supports 11 of actuating modules 12 are coupled coaxially and rigidly with retaining bushings whose length is equal to the value of the critical radius. The temperature-sensing actuating members 6 of separate actuating module 12 are connected in series into a single electrical circuits and may be positioned with their arc-shaped portion facing inward of the module. EFFECT: extended operating capabilities. 7 cl, 4 dwg
