Technical Appendix7.4.4 Indication of output rotating direction when using backstopsFor the order of a gearbox with backstop you have to indicate the required direction of rotation, viewed at outputshaft on output side of gearbox. For drives with left and right output shaft the direction of rotation is given viewed atside L. To avoid damage to the gearbox or the unit , the direction of rotation needs to be checked before operating.CW = rotation right, CCW = rotation leftCW = rotation right, CCW = rotation left7.4.5 Slip coupling in the input lanternIf an input lantern is used, it can be equipped with an additional slip coupling, if necessary, to mechanically limitthe torque of the drives. In this case, the slip coupling is installed between motor and gear unit drive shaft. In thenormal case, only the standard coupling half of the motor is replaced by the special slip coupling half.A slip coupling is a component where the permissible torque is transferred frictionally engaged. For this purpose,two spring-loaded friction linings are pressed against each other. The spring force determines the amount of torquethat can be transferred. The spring force and, subsequently, the transferable torque can be adjusted.Slip couplingT42
