The strength analysis of the butt distributors of nonadjustable hydromachines
The design model of the butt distributor of the axial-piston hydromachine is developed. An approximate analytic technique for stress determination in smooth concentrators' zones is proposed. Design dependences for determining the stresses and deformations in dangerous zones are obtained. Various variants of the butt distributor cross-sections are considered, and for them the strain and stresses analysis is carried out. Offered the approached analytical method of calculation the stresses in zones of smooth concentrators. The obtained results are analysed.
