The design of the installed EAS -elements is as descibed on page 8. The clutch is also suitable fo oil-unning. 2 Stoke 1 Design s 0 1 Fig. 1: EAS -element clutch engaged Design 2 Toque Adjustment: The limit toque fo oveload on the clutch can be adjusted by changing the cup sping pe-tension of each oveload element. Fo s 6 11, adjustment is caied out via the adjusting nut 3.7, fo s via set scews 3.11 (see Fig. 1). It is essential that all oveload elements on the clutch ae adjusted evenly. The EAS -element clutches s 6 14 can be set to the equied limit toque fo oveload at the place of manufactue. Subsequent adjustment o e-adjustment via an adjustment diagam is also possible (see Installation and Opeational Instuctions B.4.3.GB). 4 2 Makings fo e-engagement Toque Path: Hub pat 1 bolt 3.1 balls 3.3 thust piece output flange 2 Pocesses fo Toque Switch-off on Oveload: On oveload, the hub pat 1 and the output flange 2 begin to tun against each othe. The bolts 3.1 in the oveload elements ae pessed via the contol segments 3.4 against the foce of the cup spings 3.6 fom the thust washes 3.2. The contol segments 3.4 tavel adially outwads ove the bolt 3.1 switching edge and hold bolt 3.1 in a disengaged position (see Fig. 2). The positive-locking connection of the hub pat 1 and the output flange 2 is nullified. The oiginally coupled masses can slow down feely. The dive is switched off electically via speed monitoing device 4.

Table 1 M G = Set limit toque fo oveload in [knm] EAS Re-engagement: Re-engagement is caied out by applying axial pessue on the bolt end 3.1 of each oveload element. The hub pat 1 and the output flange 2 ae tuned into the coect angula position to one anothe (e-engagement position can be ecognized via the making boes on the clutch oute diamete, Fig. 2). By hitting the bolt end with a plastic hamme, the bolts 3.1 ae bought back into an engaged position. The clutch is eady fo opeation when all clutch oveload elements ae engaged. The level of engagement foce is dependent on the set limit toque fo oveload and can be calculated oughly using the fomula below. Re-engagement can also be caied out automatically using compessed ai.
