DOI: 10.1016/j.triboint.2016.12.035
Abstract: Abstract This paper researches two methods for improving the axial static and dynamic characteristics of hydrostatic lead screws, i.e. (a) using membrane restrictor instead of capillary restrictor and (b) utilizing the intentional periodic pitch errors… read more here.
