The head includes a circumferential knurled surface (23) to oppose rotational and axial forces applied to the threaded member (22), to permit application of a high clamping torque to the clamping nut (7).
The efficiency of the clamping torque applied at the end of the assembly operation may be controlled by monitoring the relative displacement of the marks resulting from the assembly.
Check loss of tightening torque of wheel fixings by retightening, not by measuring torque to loosen fixing.
The cap is screwed on by means of friction clutch means (33) that give a tightening torque less than the desired ideal torque.
In an impact screw tightening device using an electric motor as the drive source for rotation, tightening torque accuracy is improved and time required for screw tightening is reduced.
The lobes provide a tightening torque to the needle fastening head in response to a tightening force applied to the lobes by fingers of a user securing the needle to a phaco handpiece.
Therefore, phase management considering crushing transformation characteristics of a gasket is available even when the torque is lower than the specified tightening torque.
A torque multiplying wrench (10) having a jaw at one end and an adaptor (14) at the other end for receiving torque input.
When torque applied by the tool in the first hand direction exceeds a predefined magnitude the applicator and fastener will begin to unthread thus preventing any further torque from being applied.
A clamp device to develop a flange fastening force relatively larger than heretofore with a nut clamp torque relatively smaller than heretofore is provided.
Torque may also be sensed via a sensor (32) and input to the computer (20).
The invention relates to a nut (10) for limiting an effective torque and corresponding method.
The pulsating magnetic field causes the inner assembly (12) to apply a braking torque to the shaft (8).
In this respect the torque while screwing the sensors into the tissue of the patient is limited at least to a maximum, while ensuring at the same time that the torque is kept to an indispensable minimum.
