Abstract

Inventia se refera la un reductor folosit, în special, la deplasarile cu viteza mica a axului portscula, a masinilor-unelte. Reductorul, conform inventiei, este alcatuit dintr-un arbore lagaruit cu ajutorul unor rulmenti cu ace si a unei bile pe el aflîndu-se montat, excentric un rulment radial care actioneaza în timpul rotirii arborelui asupra unei roti dintate conductoare. Roata dintata se fixeaza prin intermediul unor tije elestice la o carcasa si se pozitioneaza în raport cu rulmentul prin intermediul unui inel de siguranta. Miscarea se transmite la o roata dintata condusa ce se sprijina prin intermediul unui rulment cu ace pe carcasa.The invention relates to a reducer used in particular for low-speed displacements of the spindle axis of machine tools. According to the invention, the reducer is made up of a lagged shaft by means of needle bearings and a ball on it being eccentrically mounted a radial bearing which acts during the rotation of the shaft on a conducting toothed wheel. The toothed wheel is fixed by means of some elastic rods to a casing and is positioned in relation to the bearing by means of a safety ring. The movement is transmitted to a driven toothed wheel that is supported by a needle bearing on the casing.
