Abstract:
A shaft alignment system comprising:first shaft support means for supporting a shaft, said first shaft support means having a first longitudinal axis and being rotatable about said first longitudinal axis,second shaft support means for supporting the shaft, said second shaft support means having a second longitudinal axis and being rotatable about said second longitudinal axis, andbearing means for rotatably coupling said first shaft support means to said second shaft support means, said bearing means having a bearing rotation axis, said bearing means being arranged with respect to said first and second shaft support means such that said bearing rotation axis is aligned at a first non-zero angle with respect to said first longitudinal axis and at a second non-zero angle with respect to said second longitudinal axis whereby relative rotation of said first and second shaft support means about their respective longitudinal axes varies the relative angular alignment of said first and second longitudinal axes.
