Generl technicl dt WIESEL, DYNALine, VARIOLine Liner speeds liner speed chieved by liner drive unit depends on the led of the mechnicl drive element nd on the input rottionl speed. vrious liner speeds which cn be chieved by the individul sizes re listed in the following tble: Drive Led nmx vmx element [mm] [rpm] [m/s] TGT 4 1500 0.1 8 1500 0.2 12 1500 0.3 16 1500 0.4 KGT 2) 4 3000 0.2 5 3000 0.25 10 3000 0.5 20 3000 1 40 3000 2 50 3000 2.5 VARIOLine 3000 1.5 ZRT 3) 20ATL5 120 1250 2.5 ZRT 3) 25ATL10 170 882 2.5 TGT: Trpezoidl screw drive 2) KGT: Bll screw drive 3) ZRT: Toothed belt drive Instlled position liner drive units cn be instlled in lmost ny position, provided tht ll the forces nd moments occurring remin below the mximum vlues for the xis concerned. Security dvice bll screw drives in ll three sizes re generlly not self-locking. It is therefore dvisble instll suitble mors with holding brke, prticulrly if the liner drive unit is instlled verticlly. If the othed belt breks, the lod is relesed. refore sfety precutions hve be tken for pplictions which re criticl with regrd security. Mximum forces All mximum forces nd moments provided refer the center/p of the power bridge. Lod overly t severl coordintes: If compound lods occur, with force nd moment components in more thn one direction, the mximum permissible lods must be reduced 60% of the specified mximum vlues. When forces nd moments re overlid in two or three coordintes, it is necessry reduce the mximum permissible lod 60% of the mximum vlue. Duty cycle In prctice, the following vlues hve been proven. Drive element: For trpezoidl screw the per limit should be 30% per hour, liner bll guides llow duty cycles 100%. Extremely high lods in combintion with high duty cycles cn reduce the life. Guidnce element: For sliding guide the per limit should be 30% per hour, liner bll guides llow duty cycles 100%. Temperture All series re designed for continuous opertion t mbient tempertures 80 C (176 F). Tempertures 100 C (212 F) re lso permitted for brief periods. liner drive units re not suitble for opertion t subzero tempertures. Idle rques given vlues re mens from series of mesurements. effective vlues my differ in individul cses. Strightness/rsion luminum profiles re extruded sections which my disply devitions in strightness nd rsion due their mnufcturing process. lernce of these devitions is defined in DIN 17 615. devitions found in Precision Technology USA, Inc. liner drive units corresponding these limits re worst cse, but re normlly well below. In order obtin the required guide ccurcy, the liner drive unit must be ligned with the id of leveling pltes or clmped from mounting surfce mchined with sufficient ccurcy. This ensures tht lernces of t lest 0.1 mm/1000 mm re chieved.
