GN 923.7 flat-faced solid disk handwheels are distinguished by their modern design.
These handwheels are suitable for applications where the handle must not remain in the operating position.
In order to bring the handle into the operating position it must be pulled upward 90° against the torsion spring, to a stop, and then pushed axially against the spring pressure into its hold position. By maintaining the forward thrust on the handle, the handwheel can easily be rotated. When the handle is released, the spring returns it back to the retracted position.
The removable plastic cover shrouds the assembly hardware such as screws and countersunk washers, as well as the shaft end.

The connection between the operating element and the shaft is often made by a cross pin or a grub screw. As a result, the user is faced with relatively high assembly costs since cross holes on operating elements are usually not readily available. Components with cross holes according to GN 110 are not only manufactured and supplied at very competitive prices but there is also no need for time-consuming design drawings. However, the geometrical shape of some operating elements does not allow the use of this standard. The d2 pin hole is intended for use with a spring pin. |
