Embodiment Construction

[0018] figure 1 The illustration in FIG. 1 shows a partial view of a combine harvester 22 , the structure and function of which are known in principle, so that an in-depth description of them is omitted.

[0019] A partial view of a combine harvester 22 shows a main drive 1 embodied as an internal combustion engine with a drive belt pulley 2 . Arranged on the body section 3 of the combine harvester 22 below the main drive 1 is a swivel converter 4 , which is then adjusted according to figure 2 and image 3 Explain in detail. The pivot converter 4 is drive-connected to the drive pulley 2 via a first drive belt 5 . The pivot converter 4 is drive-connected to the drive pulley 7 by means of a second drive belt 6 . In order to receive the first drive belt 5 and the second drive belt 6, the oscillating converter 4 has two outer drive belt reels 9, 10, of which only the rear side of the outer drive belt reel 9 can be figure 1 see in. Furthermore, the belt changer 4 has an adju...

Abstract

The present invention relates to a pivot variator (4). The pivot variator comprises a pivotable frame (13) and pulleys (9, 10) which are guided and fixed by the pivotable frame, between the pulleys, an axially displaceable setting disc (14) is arranged, said frame (13) includes a first frame portion (15), which is rotatable about a pivot axis (8), and a second frame portion (17), by means of at least one spring element (16a, 16b) integrated in the frame (13) opposite the first frame portion (15) biased, the pulleys (9, 10) and the adjusting disc (14) are mounted on the second frame portion, wherein the second frame portion (17) is linearly guided by the first frame portion (15).

Description

technical field [0001] The invention relates to an oscillating variator and to a combine harvester. Background technique [0002] The conversion ratio of a belt drive is generally changed by means of a so-called variator, in that the wedge-shaped pulleys lying opposite one another are designed such that their spacing can be changed in the axial direction. In order to maintain the clamping of the drive belt required for operation, several clamping elements are provided which are clamped relative to the drive belt in order to prevent slippage. Converters of this type are also used in particular on combine harvesters. These clamping means can be adjusted by the operator with regard to the pre-tensioning to be applied. However, an incorrect adjustment of the pretension can lead to a considerable reduction in the service life of the drive belt if the pretension is too high. A pretension selected too low conversely reduces power transfer. On the other hand, the pretensioning o...
