Abstract

The force rotation head has a reduction gearing driven via a hydromotor via an intermediate clutch (2), with the hydromotor enclosed by a housing (5) in the vicinity of the clutch, formed by two elastically coupled rings (10,11) secured to the housing of the reduction gearing. The clutch uses elastic torque transfer elements acting between clutch claws and preferably made of a polyurethane with a hardness between 89 and 95 Shore-A, coupled together by an inner ring of the same polyurethane material.
