Abstract

Inventia se refera la trusa pentru asamblarea organelor de masini si mecanismelor, destinata efectuarii unor lucrari de laborator si demonstratii practice în procesul de predare-învatare în scoli. Trusa conform inventiei se compune dintr-o placa de baza prevazuta cu niste canale în coada de rândunica, pe care sunt dispuse, succesiv, niste suporturi, pe care culiseaza niste lagare de alunecare, cu culisare controlata de niste mecanisme surub-piulita, lagare ce au la partea superioara un capac prevazut în interior cu un cuzinet sectionat si niste capace de etansare, precum si niste lagare de rostogolire, fiecare format dintr-un suport cu ghidaje în coada de rândunica, dintr-o tija, un butuc si un capac de etansare, pe aceste lagare putând fimontati succesic sau simultan un arbore cotit sau doi arbori drepti, functie de mecanismul care trebuie realizat. Pentru actionarea mecanismelor se utilizeaza un motor electric, prevazut cu o roata de curea si care este fixat pe un suport dispus tot pe placa de baza a trusei. Prin asamblarea elementelor din trusa se pot realiza mai multe mecanisme, si anume, un mecanism de transmitere a miscarii cu roti dintate cilindrice cu actionare elecxtrica, un mecanism de transmitere a miscarii cu roti de frictiune cu actionare electrica, un mecanism cu volant cu actionare manuala, un mecanism de transmitere a miscarii prin curele cu actionare electrica, un mecanism de transmitere a miscarii cu lant cu actionare electrica si un mecanism biela-manivela, pentru pozitionare si verificarea abaterilor fiind utilizate un dispozitiv cu comparator, un dispozitiv cu fier cu plumb si un lineal.The invention relates to the assembly of machine parts and mechanisms, intended for carrying out laboratory works and practical demonstrations in the process of teaching-learning in schools. According to the invention, the kit consists of a base plate provided with some channels in the dovetail tail, on which there are successively arranged some supports, on which slide some sliding bearings, with slide control controlled by some screw-nuts, bearings have a top cap provided with a segmented sleeve and sealing caps, as well as some roller bearings, each of which is made up of a guides in the swan tail, one rod, one hub and one cover and on these bearings can be successively or simultaneously fed a crankshaft or two straight shafts, depending on the mechanism to be achieved. To drive the mechanisms, an electric motor is provided with a belt pulley and is attached to a support placed on the base of the case. By assembling the elements of the kit, several mechanisms can be made, namely, a mechanism for transmitting the movement of cylindrical gears with electric drive, a mechanism for transmitting the movement with electric drive friction wheels, a manual steering wheel mechanism , a mechanism for transmitting the movement through electric drive belts, an electric chain drive transmission mechanism and a crank mechanism, for positioning and verifying the deviations using a comparator device, a lead-iron device and a linear one.
