ABSTRACT:
This invention relates to a rotary impulse screwing device which generates only one pulse per rotation of the output shaft. Two main and two additional lamellas are adjustably positioned in the output shaft. The two main lamellas seal at a minimum of two times per rotation of the output shaft. The two additional lamellas are adjusted independently via separate recess tracks to ensure that each additional lamella seals at only one point per rotation of the output shaft. The independently articulated additional lamellas further ensure that the load on the output shaft bearing is symmetrical on non-impulse points of rotation.
