WebJun 15, 2024 · Abstract. The epicyclic gear train (EGT) is an advanced gear transmission mechanism, which is widely applied in drive systems. It is of great significance to eliminate the same structure in the type synthesis of EGTs.

The first n − 1 columns of the matrix form the incidence matrix of a tree, so these are linearly independent. It follows that the span of these n − 1 columns is given by the subspace S ⊂ R n, defined by. S = { ( x 1, …, x n): x 1 + ⋯ ...
