Embodiment Construction

[0024] figure 1 A belt tensioner suitable for a rock crusher, in particular a cone crusher, is shown. In this case, a drive 10 in the present case as an electric motor is used. The electric motor is usually powered by a generator, which in turn is driven by the rock crusher's internal combustion engine. Alternatively, a direct drive via a switchable clutch is also conceivable. A pulley 12 is fastened in a non-rotatable manner to a transmission shaft 11 of the drive device 10 . The belt tensioner also includes a second pulley 30 coupled to the drive shaft 31 in a rotationally fixed manner. The drive shaft 31 leads to the crushing assembly of the rock crusher. The two pulleys 12 and 30 are coupled to each other by a drive belt 20 . In the present case, a plurality of individual drive belts 20 wound around the two pulleys 12 and 30 respectively are used. A belt tensioner is arranged between the two pulleys 12 and 30 . The belt tensioner here comprises two tension rollers 4...

Abstract

The invention relates to a belt tensioning device for a crusher or a screening machine for tensioning at least one circulating drive belt (20) which is deflected about a belt pulley (12) of a drive (10) and has a load strand (21) and an empty strand (22). The drive (10) can be driven with a crushing assembly, a screening unit, a generator, or the like of the crusher by means of the drive belt (20). The vibrational stress acting on the machine chassis can be significantly reduced in that the belt tensioning device has two tensioning rollers (47), each of which is rotatably mounted on a holder (41, 51) of a tensioning part (40, 50). One tensioning roller (47) is paired with the empty strand (22) and the other is paired with the load strand (21). Additionally, the two tensioning parts (40, 50) can be adjusted relative to each other between an open position and a tensioning position, in which the tensioning parts are held against each other at least opposite the tensioning direction, in particular the tensioning parts can be blocked against each other, and the complete closed system can be freely moved linearly using actuators (44.2) according to the load situation.

Description

technical field [0001] The invention relates to a belt tensioning device suitable for rock crushers, screening plants etc. for tensioning at least one revolving drive belt deflected around a pulley of a drive and having a load section and The unloaded section, where the drive unit can be driven by the crushing components of the rock crusher, the screening unit, the generator, etc. via the drive belt. Background technique [0002] Rock crushers have a drive motor, such as an internal combustion engine or an electric motor. This drives a crushing assembly, eg a cone crushing assembly, via a belt system. A belt tensioner is used to transmit the necessary tension to the drive belt or to obtain tension. This usually includes a tension roller supported by a tension arm. The tensioning arm is coupled to the machine chassis of the rock breaker via a tensioning system. During operational use, the crushing components vibrate. These vibrations are transmitted to the drive belt. A...
