The mathematical relationship between torque applied and the resulting tension force in the bolt has been determined to be as follows:Equation T = c D FTorque Axial Force Calculator - for steel and zinc plated threads. T = Torque required (inch pounds) F = Bolt tension desired (Axial Load)...
The invention discloses a method for setting bolt torque, which is used for obtaining set torque required by setting an axial force of a bolt, so as to assemble the bolt. The method comprises the following steps: assembling the bolt in a test tool, and exposing a bolt cap and a bolt ...
According to the product provided by the utility model, the test nut can measure the friction torque of the ball screw under the axial force; measurement value data of the friction torque of the screw are simply and efficiently acquired; interference of other torque or force is prevented; and...
The transmission drives in axial displacement the element and enclosure with respect to each other and is rotatably driven by an electric motor (21) e.g. direct current motor, whose motor shaft drives the screw or a coupling part (6). The transmission is driven with a reduced torque, ...
Statistical analysis revealed that locking torque and angle are relevant parameters affecting ATE (p< 0.001). Image processing parameter—threshold is also influencing the ATE (p< 0.001). The combinations between torque, angle and threshold were not found to be significant factors (p> 0.005). The...
