Embodiment Construction

[0025] figure 1 Shows a top view of a belt drive 1 for driving an object, which is mounted in a rotatable manner, comprising: a basic body 2 and two pulleys 3, 4, means for generating a pretension 5 and a continuously looping belt 6 around pulleys 3, 4, wherein the first pulley 3 can be connected to a drive 7 and the second pulley 4 can be connected to an object, or the first pulley 3 is connected to a drive 7 and the second pulley 4 is connected to the object. Objects are not drawn for clarity reasons.

[0026]The mechanism 5 comprises in this embodiment two rollers 8 , 9 arranged on opposite sides of the rod 10 , and a rod 10 mounted in a pivotable and displaceable manner on the basic body 2 , and the rollers contact the return sections 11, 12 of the belt 6 respectively. Two spring elements are arranged between the mechanism 5 and the basic body 2 . The two spring elements 13 , 14 are designed as ring springs. Said spring element supports the rod 10 and thus the mechani...

Abstract

A belt drive (1) for driving an object, said object being rotatably mounted, comprising: a basic body (2) and at least two pulleys (3, 4), for producing Mechanism (5) of pretension and continuously circulating belt (6) around pulleys (3, 4), wherein the first pulley (3) can be connected to the drive (7) and the second pulley (4) can be connected to the object connection, or the first pulley (3) is connected to the driver (7) and the second pulley (4) is connected to the object, characterized in that the mechanism (5) has at least two rollers (8, 9), Said rollers are arranged on opposite sides of a rod (10) which is pivotally mounted on said basic body (2) and contact respectively a return run (11, 12) of a belt (6) , wherein the rod (10) is loaded by at least one spring element (13, 14) and is movable relative to the basic body (2).

Description

technical field [0001] The invention relates to a belt drive for driving an object mounted in a rotatable manner, said belt drive comprising: a basic body and at least two pulleys, a mechanism for generating pretension and a continuous loop A belt around pulleys, wherein a first pulley is connectable to a drive and a second pulley is connectable to an object, or the first pulley is connectable to a drive and the second pulley is connectable to an object. Background technique [0002] Usually, in belt drives, the pretension of the belt and a specific wrap angle on the pulleys are ensured via spring-loaded roller elements or by means of an eccentric connection of the roller elements. This is a complex construction which is difficult to integrate into the narrow installation space. Furthermore, with this pretensioning of the belt, only a certain pretensioning force can be achieved and the belt is always loaded with the maximum pretensioning force, even when stationary. Conte...
