Tensioning roll for an endless drive in an internal combustion engine, in particular linear tensioner for v-ribbed belt

摘要

The invention relates to a tensioning roll for an endless drive in an internal combustion engine, in particular a linear tensioner for v-ribbed belt, comprising a support part which is rigidly connected with the internal combustion engine (6a, 6b), a support part is connected with the adjustable bearing part (1), a in the bearing part is rotatably mounted tensioning roller (3) and a on the supporting portion and on the bearing part, which supports regulatory member (9). In the supporting part (6b) and in the bearing part (1) are two bores are provided, whose axes are at right angles to the axis of rotation of the tensioning roller, whereby one of the two bores is configured as a threaded bore. Said regulatory member is formed as an adjusting screw (9) through the bore can be screwed into the threaded bore, wherein the head of the adjusting screw on which the bore hole part (bearing part or support part) is applied. On the bearing part (1) and on the support part (6a) are to the axis of rotation of the adjusting screw (9) arranged parallel support surfaces. In a part (bearing part or support part) is a to the axis of the adjusting screw parallel elongated hole (4) is arranged, and in the other part (supporting part or bearing part) is a congruent with the slotted hole arranged threaded bore hole (7a). In the threaded bore (7a) is a the elongated hole (4) screwed into the guide bolt (8) which passes through.
