2 Elctromagntic tooth clutchs with slip ring Elctromagntically opratd A B - torqu transmission via shaft (fig.19) - torqu transmission via toothd fac (fig.20) For both typs th aformntiond slction critria hold. For clutchs typ A and th sizs 13 to 100 Nm th distanc th slip ring from th fac amount to 1.5 mm only. This insulating spacing is too small for situations whr an adjacnt machin part is protruding, thrfor an intrmdiat washr or collar nds to b includd (fig. 8). Ring magnts within clutchs typ B partially hav a larg boring diamtr d, which rquirs filling with frromagntic matrial (up to diamtr g), if th full torqu th clutch is to b achivd. Ths clutchs ar suitabl for both dry and lubricatd opration. Th currnt ladrs ar howvr diffrnt. For dry opration th brushs consist Cu-Graphit and for lubricatd opration (oil) bronz tissu nvlopd in a brass sht. Th currnt ladrs must b fixd rigidly i.. vibration-fr and with th indicatd distanc from th surfac th slip ring ( s tabl pag 14). It is advantag, if th currnt ladrs sit at wll accssibl placs, such that thy can b xamind asily aftr longr opration and brushs b rplacd if ndd. For clutch shafts with rolling bars it is rcommnd to ralis th lctric arthing via th ring magnt or a part connctd to th ring magnt by a currnt lad (fig. 19) This is mandatory for clutch shafts with friction baring. For shafts with rolling bars on can achiv a bttr arthing which input tnsion (pr-strssd baring). Th max. prmissibl rvolution spd is indicatd in th tabl th tchnical shts. It dpnds on th max. prmissibl gliding spd th brush. For lubricatd opration it is mandatory to attach a blind brush, onc th rvolution spd xcds th limit allowd for opration without a. Evn at lowr rvolution spds a is mandatory, if th clutch is narly constantly switchd on. A is a currnt ladr, that is not attachd to th lctric circuit. Its task is to brak th oil film on th slip ring. Elctromagntic tooth clutchs with slip ring ar maintnanc-fr. For dry opration only th gliding surfacs th pins nd to b coatd occasionally with a lubricant (.g. Molycot). For th cas a spcial dsign as rtaining clutchs (fig. 21 and 22) th slip ring is absnt. Th nds th coil ar thn ld out ithr as braid or attachd to an AMP-connctor (compar to th clutchs without slip ring). All othr dimnsions corrspond to th valus givn in th tabls th tchnical shts for typ B clutchs. Clutchs with spcial tth hav th sam dimnsions as thos with normal tth. Whn placing th ordr plas b awar that in th cod th scond numbr bhind th point changs as follows: Only for th fixd point switching also th third numbr bhind th point changs in th cod. It givs th numbr latching possibilitis within a complt rvolution (360 ). As xampl: Th cod MZ dsignats an lctromagntic tooth clutch with fixd point switching having two ngaging positions pr rvolution (180 -switching).
