Abstract

Inventia se refera la constructia de masini, si anume la variatoarele mecanice.Variatorul precesional, include o carcasa 4, in care este amplasata o roata centrala 2 cu suprafata interioara sferica si care este legata rigid cu arborele condus 3, un satelit 1 care contacteaza cu suprafata sferica a rotii centrale 2, arbore conducator 11. Noutatea inventiei consta in aceea ca satelitul 1 este instalat pe un suport sferic 7 legat rigid cu arborele conducator 11. Pe un suport sferic 7 este instalat un disc 20 cu corpuri de rulare 21, fixate in furci 24 legate cu doua suruburi 25 si 26, unul dintre care este executat cu filet dreapta, iar celalalt - cu filet stinga, iar ambele se afla in angrenaj cu o piulita 27.The invention relates to the construction of cars, namely to mechanical variants. The precessional drive includes a housing 4, in which a central wheel 2 with a spherical inner surface is located and which is rigidly connected to the driven shaft 3, a satellite 1 which contacts with the spherical surface of the central wheel 2, the driving shaft 11. The novelty of the invention consists in that the satellite 1 is installed on a spherical support 7 rigidly connected with the driving shaft 11. On a spherical support 7 a disk 20 with rolling bodies 21 is installed, fixed in forks 24 connected with two screws 25 and 26, one of which is executed with the right thread, and the other - with the left thread, and both are in gear with a nut 27.
