Deformative Performances of the Oil Distribution Box Ring and Bearing in Controllable Pitch Propeller Hydraulic System

다국어 초록 (Multilingual Abstract)

Accuracy of the controllable pitch propeller setting beside other reasons are defined by deformation conditions of the oil distributions box bearings, which provide oil distribution ring operation. The deformative displacements for high and low pressure of the supplying lines were defined for surfaces of the oil distribution ring bearings for operative pressure of the controllable pitch propeller system. The deformative displacements in high and low pressure of the supplying lines were defined for bearings of babbitt and polyamide materials. The advantageous for polyamide deformative properties were found. The difference of the babbitt and polyamide material deformative displacements and value of the maximum stress, which define for cyclical load of the bearing to estimate the fatigue properties of the bearing body structure and for babbitt and polyamide attachment to steel OD box ring have been estimate.
