Embodiment Construction

[0233] exist Figures 1 to 3 A first embodiment of the mechanical component engagement according to the invention is shown in FIG. 1 and is generally designated 10 .

[0234] The part cooperation 10 has a first part 12 in the form of a free wheel and a second part 14 in the form of a fixed wheel. The fixed wheel 14 is the active part in the shown case. The free wheel 12 has a first part toothing 16 . The fixed wheel 14 has a second part toothing 18 .

[0235] Freewheel 12 is driven in drive direction 20 by means of fixed pulley 14 . Here, the reverse tooth flank 22 of the second tooth section 18 is connected to the rear tooth flank 26 of the first tooth section 16 .

[0236] The toothing 16, 18 is designed with a certain backlash between figure 1 Expressed in 24.

[0237] The backlash 24 is the distance between the rear flank 28 of the second toothing 18 and the reverse flank 28 of the first toothing 16 in the illustrated case.

[0238] Such toothings are generally know...

Abstract

The invention relates to a structure of mated parts (10) comprising a first part (12) having first teeth (16) and a second part (14) having second teeth (18) that engage with the first teeth (16) to transmit a drive force in a drive direction (20) via the teeth (16, 18), the first part (12) being provided with first anti-rattle teeth (32), and an anti-rattle part (30) being fastened to the secondpart (14) and having second anti-rattle teeth (33) that engage with the first anti-rattle teeth (32). The structure according to the invention is characterized in that the anti-rattle part (30) is received in such a manner that it can be off-set relative to the second part (14) in the direction of drive (20), the second part (14) and the anti-rattle part (30) being associated with respective friction sections (44, 46) that frictionally engage (38) with each other.

Description

technical field [0001] The invention relates to a mechanical component matching structure, which is composed of a first component with a tooth portion of the first component and a second component with a tooth portion of the second component, the tooth portion of the second component is in mesh with the tooth portion of the first component, In order to be able to transmit the drive force in the drive direction via the component toothing. Background technique [0002] Such component engagements are well known, for example in the form of gear pairs and / or pinion gear engagements. These component arrangements are frequently used in drive trains of motor vehicles, for example in stepped transmissions, in drives of auxiliary devices, etc. [0003] A major problem with this mechanical component fit is the so-called rattling phenomenon. This phenomenon is primarily caused by vibrational excitations in the drive train, for example produced by a drive motor of the drive train, for ...
