Abstract

Torsion spring arrangement (4) for counterbalancing a roller shutter in a building, which is guided movably up and down at least in the direction of a component of motion, the displacement motion of which shutter being converted into the rotation of a shaft (2) running approximately coaxially with respect to the spring arrangement (4) and by means of which a rotary motion is applied to one end of the spring arrangement (4), whose other end is supported against twisting, in such a way that when the shutter moves downwards, the said spring arrangement tightens, accumulating energy, and releases the accumulated energy during the upward movement; for the purpose of simpler manufacture, and to reduce the risk posed by breakage of the spring spiral, the torsion spring arrangement is designed in such a way that a plurality of single torsion springs (10) are arranged around the shaft spindle (2) outside the shaft or distributed over the shaft circumference within the said shaft on the inner peripheral wall thereof, the one ends of which springs being put together in such a way as to transfer energy in the same direction via a gear device and the other ends of which springs being put together rigidly with respect to the energy transfer to which they are subjected. <IMAGE>

SU420832A1 (en) PULSE SPEED VARIATOR1 The invention relates to adjustable mechanical transmissions of a pulse action and can &#39;find. Application in drives of various&#39; Purpose, for example in drives of plastics and rubber processing machines. Pulse velocity amplifiers are known, comprising a housing and a master and the driven shaft, the converting mechanism in the Kvodoshilno-rod-and-pinion mechanism, the freewheel clutch. and the adjusting mechanism. The disadvantages of the known variator are the cumbersome design and the impossibility of getting and the optimal law of motion; Neither the link of the link. With the aim of enhancing the structure and obtaining the optimal value of the law of the motion of the driven link, each transforming mechanism is made in the form of a spreading rocker mechanism, including rollers, installed uniformly around the circumference on the outer ring of the corresponding coupling of the free stroke, and the helical cam interacting with the housing and the rollers. FIG. 1 shows the pulse speed variator, general view; in fig. 2 - the same, section. A - A. FIG. one; in fig. 3 is a graph of the change in the gear ratio from the driven cage of the one-way clutch to vedu-2iB P T BFSH! To the inoperative shaft of the variator depending on the angle φ of rotation of the latter 15 ° and 60 °; in fig. 4 is a graph showing the change in the gear ratio of the variator from the driven shaft to its leader, 5 depending on the angle φ of rotation of the next section at 15 ° and Y 60 °. The variator has a driving shaft 1 installed coaxially with the driven shaft 2 on the bearings in the housing 3, and the disk 4, hingedly connected in the center with the drive shaft 1, rods 5 with different lengths and equal mass m., equally spaced relative to the axis of the driven shaft 2 of the cylindrical surface and set movably in Enclosure 3. When it is 15 M, the free ends of the plugs 5, extending to disk 4, interact with the latter, for example, via hydrostatic slide bearings (or rolling bearing). The other ends of the rods 5 are fastened to the screw cam-20. 6, each of which with its flat surface interacts with the housing 3 through a cyclical roller 7 with a fixed axis of rotation and a screw surface with the outer race 8 of the freewheel through -25 a cylindrical roller 9, the axis of rotation of which is bonded to the freewheel 8 of the overrunning clutch. The hubs 10 of the free-wheeling clutch are fastened with the known shaft 2, and their clips 8 are spring-loaded relative to the building 30 sa 3 in a circular direction, for example.
