4 6 7 8 Markings shown in perfect adjustment pre assembled Torque adjusted TorqueAdjustments DA00 - DA5 On the face side of the pressure ring ➍ and on the outer side of the adjustment nut ➐ are markings. These are necessary for the adjustment of the torque as follows. To begin with, the adjustment screws ➑ are being screwed out of the nut so far, that they do not stand out. After this the adjustment nut ➐ will be screwed hand tight against the safety disc ➏. At the same time the markings on the adjustment nut ➐ will be matched with the nearest marking on the pressure ring. ➍ Now the adjustment screws ➑ are being tightened completely into the adjustment nut ➐ and the maximum torque is obtained. If a lower torque adjustment required, the adjustment nut ➐ has to be turned back to the correspondingmarkings after the initial adjustment.After this the adjustment screws ➑ have to be tightened again. Generally a stepless torque adjustment even betweenmarkings, is possible. For adjustments in the lower torque area a clamping nut is recommended. General notes The break loose moment of torque limiters is in the average about 20%above the dynamic slippage. The torque depends greatly on the surface quality of the driven part, the break-in period and the tolerances of normparts. The driven part should ideally be ground. Very negative are the effects of oil, fat and dampness for the set torque. 8 7 4 4 6 7 8 www.jbj.co.uk/torque-limiting-couplings.html 18 #DriveLineHarmony Torque Limiting Couplings Adjustment
