10 FRICTION TORQUE LIMITER DF : additional information VERSIONS ON REQUEST /CM: minimum torque version Helical springs execution, for a higher torque range and consequently, a finer adjustment on calibration is possible Stainless steel ring /EA: rust resistant Rust resistant execution, with stainless steel rings and galvanized for application in wet environments. 10 /MFR: reduced flange hub version Reduced flange hub execution, to assemble elements with reduced diameters. Available with two or three bushes versions. /MS: overload's assembly version Our suggestion to increase the life of the friction rings and to maintain the torque limiter efficiency, is (it is possible and advised) to stop the machine immediately, on the first slip caused by an overload. This is possible by using one proximity inductive sensor, which registers any speed anomaly, as indicated in the picture.

12 FRICTION TORQUE LIMITER DF : additional information PLATE WHEELS The drive member selected (plate wheels, pulleys, gears, and so on) to be incorporated into the friction device, must adhere to predetermined characteristics (ex. the surface in contact to the friction rings with roughness Ra=0,8 : 1,6) to ensure compatibility with the chosen friction device. In the table below, there are standard plate wheels of the production schedule ComInTec's (supplied already grounded) which can be assembled on the torque limiters; and the minimum chain passage V (see picture 3), necessary for the correct sizing of the plate wheel to avoid contact between the chain and outside diameter of the limiter. It is possible to assemble various types of plate wheels, but the surfaces must be machined, and the chain passage cannot be smaller than this value. Another aspect to take into consideration to ensure the dimension of the group is correct, is the element thickness and its relevant bush N (see picture 1). We suggest to obtain a quote N equal to [S+G+1].Comparing N value obtained, to the Nstd indicated on the table, which corresponds to the standard length of the bushes, you can have: N < N std (picture1-ex.a) lowerthebush till quote N. N > N (picture 2-exB) toobtainachip-forming machining in the organ of equal diameter to A+1 and of equal depth to x (N - N ). std std Example A (see picture 1) 1.70 with plate wheel #7 G=7mm S=4mm N=S+G+1=4+7+1=12 N std = 15 To reduce the bushing carrying it to 12 mm. Example B (see picture 2) 1.70 with plate wheel #13 G=13mm S=4mm N=S+G+1=4+13+1=18 N std = 15 To create a chip-forming machining ø71 with deep 3 (quote x =18-15=3) where: p = pitch [in] G Z = thickness of the grounded element = teeth number dp = pitch diameter S = thickness of the standard bush N = thickness of the standard bush N = thickness of the calculated bush (S + G+ 1) A = outside diameter of the torque limiter V = inside diameter of the chain x std = depth of the chip-forming (N - N ) std pct 1 pct 2 12 pct 3 Code single plate wheel P G dp S NStd A V Z DF DF/SI [in] [mm] [mm] [mm] [mm] [mm] [mm] EDF/F DSF/TF/AP DSF/TF/AP/SI /8" 5, ,80 2 5, P /8" 5, ,82 2, P P , P P05 3/8" 5, , P P05 1/2" x 5/16" 7, , P /8" 5, , P /2" x 5/16" 7, , P P P05 5/8" 8, , P /2" x 5/16" 7, , P /8" 8, , P /4" 10, , P P P05 5/8" 8, , P /4" 10, , P " 16, , P P P " 16, , P P P " 16, , P P " 1/4 18, , P " 1/4 18, , P P " 1/4 18, , P P " 1/2 23, , P P " 1/2 23, , P P " 1/2 23, , P P20 -

30 BACKLASH FREE TORQUE LIMITER DSS/SG : additional information VERSIONS Positive Version ( / P) Force (N) Torque (Nm) Torque calibration (Nm) This allows for a simpler and more linear calibration. Moreover, during the disengagement it creates an increase in the torque, caused by the compression of springs, which, on presence of a non-homogeneous (but normal) transmission, for the kind of work made, can be useful to avoid frequent disengagements and machine stops. Displacement (mm) Time (sec) Negative Version ( / N) Force (N) Torque (Nm) Torque calibration (Nm) It generates an immediate torque reduction, as soon as there is a minor overload, with consequent disengagement of the limiter and immediate stop of the machine. This characteristic is very useful on sensitive applications where even a slight increase of the loads can cause damage to the machine or to the machine product. displacement (mm) Time (sec) 30 TORQUE REGULATION Positive version ( / P) As with the majority of ComInTec TORQUE LIMITERS, by turning the adjuster nut clockwise the disengagement torque increases. On the contrary turning it counterclockwise, you obtain a reduction of the torque. DSS/F/SG positive version Negative Version ( / N) DSS/F/SG negative version + Hub Nut DSS/F/SG negative version 7 5% - MAX Adjustment of the Negative version is opposite to all other units in our range. Unlike the traditional units, by rotating the adjuster nut clockwise the disengagement torque will reduce, and therefore to increase the torque the nut must be rotated anti-clockwise. To assist the operator in setting, there are clear markings on the nut showing 75% of the max torque and +/- Min/Max directions indicated. Unless otherwise requested, these models are supplied already pre-calibrated at 75% of the maximum torque value of the spring's chosen configuration.
