is calculated for force-fit clamping with a coefficient of static friction of 0.1 and a safety factor of 2 against workpiece slippage at acceleration due to gravity g. In the case of form-fit gripping, significatnly higher permissible workpiece weights are possible.
Example: - For the catalog-specified workpiece weight of 5 kg Gripping force of the gripper 1,000 N Coefficient of friction μ 0.1; safety factor 2; g 9.81
The mechanical gripping force maintenance device ensures that a minimum clamping force will be applied even if there is a drop in pressure. In the AS/S variant this acts as a closing force, in the IS variant as an opening force. Besides this, gripping force maintenance can be used to increase gripping force or for single actuated gripping.
