Abstract

The reciprocating drive has a spindle (1) mounted for rotation in a housing (4) and carrying a nut (5) for positioning the spindle. The spindle nut has a rotation lock formed by a tube (9) surrounding it and with an insert (10) to engage the spindle. The insert has an outer surface with two transverse recesses to receive wedges (22).
