Abstract
A force transmission or transport device having a line of force transmitting elements (2), a guide (1) for guiding the line of force transmitting elements (2) along a predetermined course, and at least one drive. A tensioning drive (6) is provided at one end of a section (5) of the predetermined course. A further drive (3), or an intermitting stop (9), is provided at the other end of the section (5) for tensioning the line of force transmitting elements (2) by a tractive or a compressive load. The further drive (3) or stop (9) acts substantially without slippage on the force transmitting elements (2). The tensioning drive (6), via a friction clutch, starts slipping when the desired tension has built up.
Claims15
A force transmission or transport device comprising a line of force transmitting elements (2), guide means (1) for guiding the force transmitting elements (2) along a predetermined course and at least one drive, wherein the at least one drive displaces force transmitting elements (2) actively in one location of the predetermined course and wherein force transmitting elements (2) displaced by the drive displace further elements by pulling or by pushing, wherein, for tensioning the line of force transmitting elements (2) in a section (5) of the predetermined course, a tensioning drive (6) acting on the elements (2) via a friction clutch is provided on one end of the section (5) and a further drive acting on the elements (2) substantially without slippage is provided on the other end of the section (5), wherein the driving speed (Vs) of the tensioning drive (6) is different from the driving speed (V) of the further drive (3).
A force transmission or transport device comprising a line of force transmitting elements (2), guide means (1) for guiding the force transmitting elements (2) along a predetermined course and at least one drive, wherein the at least one drive displaces force transmitting elements (2) actively in one location of the predetermined course and wherein force transmitting elements (2) displaced by the drive displace further elements by pulling or by pushing, wherein, for tensioning the line of force transmitting elements (2) in a section (5) of the predetermined course, a tensioning drive (6) acting on the elements (2) via a friction clutch is provided on one end of the section (5) and an intermittent stop (9) acting on the elements (2) substantially without slippage is provided on the other end of the section (5), wherein the driving speed (Vs) of the tensioning drive (6) is different from the speed (V) at the stop (9).
