Let R be a semiprime ring with the maximal right ring of quotients Q mr . An additive map d : R → Q mr is called a generalized skew derivation if there exists a ring endomorphism σ : R → R and a map such that for all x , y ∈ R . If σ is surjective, we determine the structure of generalized skew derivations for which there exists a finite number of elements a i , b i ∈ Q mr such that d ( x ) = a 1 xb 1 + ⋯ + a n xb n for all x ∈ R .
