Anti-twist locking means for rotary piston drives in working cylinders

摘要

The twisting occurring due to the linking of the working cylinder (serving as measuring cylinder) to the face conveyor on the one hand and the support on the other hand and the play occurring in the fastening lugs are reliably prevented by at least one fastening lug being designed to have a pivot bearing. This pivot bearing not only enables the twisting occurring between the fastening points to be compensated for but also equally enables very close tolerances in the fastening lugs to be adhered to so that the play inevitably occurring there is kept small. This play can then be further reduced by a free-wheel for securing the measurement in each case in only one direction being connected in series with the rotary potentiometer which is integrated in the cylinder housing.
