They can also be used to soften hard startsby limiting the initial torque.ConstructionA ground sprocket is fitted between two friction linings andsupported on a special sleeve. The limiting torque is controlledby rotating a ring nut (or with tension bolts on the larger versions).Advantages of Optichain-RN torque limiters are:● wide range of torque● variable torque adjustment● corrosion resistant surfaces● asbestos free friction linings● easy assemblyTo guarantee a constant exact response from the torque limiterthe friction linings must be totally free from grease. Prior to fulloperation the torque limiter should be run in for a short time toremove any rough spots from the linings and the ground sprocket.We recommend that the unit be allowed to slip for about 4 minutesat 60 rpm or thereabouts at 70% of the maximum torque.The torque figures given are the initial breakaway torques. Theslip between the sprocket and the linings begins when thesefigures are exceeded. The actual slipping torque is only about90% of these figures. This difference between the breakawaytorque and the slipping torque is due to the different coefficientsof friction applicable when there is no slip to when componentsare slipping.98* Non stock items ** on request We reserve the right to make technical changes
