Title:
DRIVEN ROLLER ELEMENT AND DRIVE UNIT COMPRISING SUCH A ROLLER ELEMENT
Document Type and Number:
WIPO Patent Application WO2005113392
Kind Code:
A3
Abstract:
The invention relates to a roller element (10) which has a central body (1) and a roller unit (2). Said roller unit (2) is mounted so as to circulate on a non-circular race (21) about the central body (1) and so as to be mobile with respect to the central body (1) by the rolling movement of the rollers (3) of the roller unit (2) on the central body (1). The rollers (3) are provided on the exterior of the roller unit (2) for rolling off on a rigid counter body (5). The roller element (10) is provided with drive means (6) which engage with the roller unit (2) and drive the same in relation to the central body (1). The roller unit (2) is directly driven by engagement of the drive means (6) between the rollers (3) and is pulled or pushed on the race (21) about the central body (1). At least in those sections where the central body (1) puts pressure on the rollers (3) with regard to the counter body (5), the rollers (3) roll off on the central body (1), thereby propelling on their other face the roller element (10) as a whole in relation to the counter body (5).
