Note: make sure that the performance features required correspond to those described above, otherwise it will be
necessary to choose a different model from the broad range offered by OBER.
CLUTCH
The gear clutch is mounted on the tool-bearing spindle in the front part of the
screwdriver. It has the function of transmitting to the bit, and therefore to the screw,
only part of the torque that may be produced by the screwdriver so as to ensure
optimal screw-tightening conditions. It also makes it possible to maintain a highly
constant level of torque when tightening screws in sequence. When the resistance
offered by the screw has reached the maximum level allowed by the clutch setting, the
teeth skip to prevent the torque transmitted from exceeding the preset level. The
range of clutch settings is determined by the spring (1) that locks the toothed disks (2).
When choosing a spring, it is always advisable to make sure that the levels of torque you wish to obtain are situated
towards the middle of its range of settings. With the same screwdriver and the same spring, the effective torque applied to
the screw strongly depends on the degree of rigidity of the joint. Other conditions being equal, pliable or elastic joints may
determine a considerable reduction in torque. All the values shown in the diagrams and tables refer to rigid joints.
