According to the invention, the teaching model comprises mainly a wheel (1) fixed at the end of a shaft of an electric motor (2) which is suspended on an arm (3) which is mounted, in its turn, by means of a sliding bearing, on a fixed central axle (4), the wheel (1) being provided on its circumference with a rubber bandage (7) and acting by friction both on a cylindrical housing (5) and a central wheel (6) mounted on the same axle (4), the motor (2) being supplied by means of a commutator brush (8) which steps on a brass ring (9) located on an electrically insulated support (10) and connected to a voltage source.
Invenţia se referă la un model didactic utilizat în scop demonstrativ. Modelul didactic, conform invenţiei, este alcătuit, în principal, dintr-o roată (1) fixată pe capătul de arbore al unui motor electric (2) ce este suspendat pe un braţ (3) care este montat, la rândul său, prin intermediul unui lagăr de alunecare, pe un ax (4) central fix, roata (1) fiind prevăzută pe circumferinţă cu un bandaj (7) din cauciuc şi acţionând prin fricţiune asupra unei carcase (5) cilindrice, cât şi asupra unei roţi (6) centrale, montată pe acelaşi ax (4), motorul (2) fiind alimentat cu ajutorul unor perii colectoare (8) ce calcă pe nişte inele (9) de alamă, plasate pe un suport (10) electroizolant şi conectate la o sursă de tensiune. |
