2 TORQUE LIMITERS - CLUTCHES: introduction ComInTec torque limiters are mechanical components necessary to fit along the kinematic chain and are preferred to electronic safety devices because of a better response time, improved reliability, excellent configuration flexibility, easy fitting and adjustment, use at high speeds in hard environments in the presence of inertias and important masses. In fact the electronic systems, which normally act up to the transmission, present: delayed reaction time, many factors as a source of error, configuration and management complexity. The fitting of the mechanical torque limiters along the kinematic chain is therefore necessary for a reliable and complete protection, in order to improve the level of safety and the machine, according to the new EN ISO standards, reducing the average possible broken-down and unproductive downtime. Benefits of our models Long product life with continuous reliability. Optimum protection against environmental conditions. Simple mounting for in-line and parallel transmission. Easy setting and adjustment. Highly accurate and fast machine protection. Special designs to suit specific applications possible. Competitive pricing without sacrificing quality. "Made in Italy" with certified quality. Our product range... "DF": Simple, economical and suitable for dry and dusty conditions.

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 driving part selected (plate wheels, pulleys, gears, and so on) to be incorporated into the friction torque limiter, must adhere to predetermined characteristics (ex. the surface in contact to the friction rings with roughness Ra=0,8 : 1,6) to ensure good performance. In the table below, there are standard plate wheels in ComInTec's production (supplied already grounded) which can be assembled on the torque limiter; 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 assembly 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 (picture 1 - ex.a) reduce the bush width to quote N. N > N (picture 2 - exb) machine the driving part at a diameter of "A+1" and a depth equal to x (N - N ). std std Example A (see picture 1) 1.70 with plate wheel #7 G = 7 mm S = 4 mm N = S + G + 1 = = 12 N std = 15 Reduce the bush width to 12 mm. Example B (see picture 2) 1.70 with plate wheel #13 G = 13 mm S = 4 mm N = S + G + 1 = = 18 N std = 15 Machine ø71 with depth (value x =18-15=3) where: p = pitch [in] G = thickness of the ground element Z = teeth number dp = pitch diameter S = thickness of the friction ring N std = 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 = depth of the machining (N - N std) pct 1 pct 2 12 pct 3 Code for single plate wheel P G dp S N Std 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 /8" 5, , P P , P P /2" x 5/16" 7, , P P P05 5/8" 8, , P /2" x 5/16" 7, , P /4" 10, , P P P /4" 10, , P " 16, , P P P /4" 10, , 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 - On request

32 BACKLASH FREE TORQUE LIMITER DSS/SG : additional information VERSIONS Calibration torque (Nm) / P Positive version (progressive spring) Forza (N) Displacement (mm) Coppia (Nm) Time (Sec) This allows for a simpler and more linear calibration. Moreover, during disengagement it creates an increase in the torque, caused by the compression of springs, which, on presence of a non-homogenous (but normal) transmission, can be useful to avoid frequent disengagements and machine stops. Calibration torque (Nm) / N Negative version (regressive spring) Force (N) Displacement (mm) Torque (Nm) Time (Sec) 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 drive. 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. 32 TORQUE REGULATION / P Positive version (progressive spring) 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 / N Negative version (regressive spring) DSS/F/SG negative Version + 7 5% Hub Nut DSS/F/SG negative Version - 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 pre-calibrated at 75% of the maximum torque value of the spring's chosen configuration.
