Description
кольцевым пазом 9, ,установленных с посто нным зазором 10 между ними,an annular groove 9, installed with a constant gap of 10 between them,
.привод-11 осевого перемещени цилинд- рического ротора 8, приспособление 12. Drive-11 for axial movement of cylindrical rotor 8, special tool 12
.дл передач гибкой т ги 4 в зазор 10 роторами 7 и 8, приспособление 12 состоитиз пары направл ющих роликов 13 и i4j захоима 15 и пары тол кающйх роликов 16 и 17,. for the transmissions of the flexible cable 4 into the gap 10 by the rotors 7 and 8, the device 12 consists of a pair of guide rollers 13 and i4j of the clamp 15 and a pair of pushing rollers 16 and 17,
Устройство работает следующим об. резом. .Образцы 18 закрепл ют в захватах 2 и 3, Гибка т га 4 фиксируетс в зажиме 15 и между роликами 13, 14 16 и 17 приспособлени - 12. Разгони етс двигатель 5 с коьшческнм ротором 7. После достижени задшшой скорости одновременно приспособление 12 направ л ет гибкую т гу 4 в зазор .10 между роторами 7 и 8, и включаетс привод 11 осевого перемещени щшиндр гческо го ротора 8, При этом обеспечиваетс заданный зшсон деформировани образца за сч изменени скорости перемещени гцбкой т г; 4 и изменени диаметров контакта ленты с ко. ническим ротором .7, так как гибка т га 4, расположенна в кольцевом пазу 9 ротора 8 перемещаетс вдоль образующей ротора 7 вместе с пазом 9 ротора 8.The device works as follows. rezom. .Samples 18 are fixed in grips 2 and 3. The bending pull 4 is fixed in clamp 15 and between rollers 13, 14, 16 and 17 of fixture - 12. Engine 5 accelerates with a standard rotor 7. After reaching the top speed, simultaneously adjusting 12 of the direction l It provides a flexible pull 4 into the gap .10 between the rotors 7 and 8, and the actuator 11 is engaged in axial movement of the axial rotor 8. This provides a predetermined amount of deformation of the specimen by changing the speed of movement of the hydraulic cylinder; 4 and changes in the diameters of the contact of the tape with co. 7, since the flexible cable is ha 4, located in the annular groove 9 of the rotor 8 moves along the generatrix of the rotor 7 together with the groove 9 of the rotor 8.
Применение кошшеского ротора 7 с пр молинейной образующей обеспечивает линейный изменени скорости деформировани , пропорциональныйThe use of a Koshish rotor 7 with a straight line generates linear variations in the strain rate proportional to
tga , где а угол между образующей и осью конического ротора 7. В случавд если необходимо обеспечить другой закон изменени скортюти доформации , и возможно применение конического и цилиндрического роторов с непр молинейными образующими.tga, where a is the angle between the generator and the axis of the conical rotor 7. In the event that it is necessary to provide another law of change for the skortyuta formation, it is possible to use conical and cylindrical rotors with non-linear generators.
