Description
Technical field
The present invention relates to tuning for Controllable Pitch Propeller technical field, in particular to a kind of installation method of distance-adjustable oar hub.
Background technique
The working principle of adjustable pitch propeller (abbreviation tuning for Controllable Pitch Propeller) is to drive propeller hub oil cylinder, Jin Ertong by hydraulic system
Crossing the crank-slide block mechanism being arranged in propeller hub mechanism makes blade around the axis rotation perpendicular to paddle shaft, thus change screw pitch,
Realize speed change, positive vehicle and the reversing of ship.
In tuning for Controllable Pitch Propeller, crank disc is mounted in the inner cavity of paddle shell, and blade is connected as by blade root bolt with crank disc
One, the inner wall of paddle shell are equipped with a circle bearer ring, and bearer ring is between blade and the connector of crank disc, and bearer ring
Separate crank disc end face and blade close crank disc end face between have a gap, this gap is called blade axial direction
Gap.
In the implementation of the present invention, the inventor finds that the existing technology has at least the following problems:
The size of blade axial gap is related with blade, crank disc, the relative dimensions of three parts of paddle shell, in practical peace
