Embodiment Construction
[0026] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.
[0027] Controlled pitch propeller is a form of ship propulsion widely used at present, and more and more ships use controllable pitch propeller as propulsion device. The oil distributor is an important part of the controllable pitch propeller. The oil distributor usually includes a valve core rod, an oil distribution shaft and a casing. The valve core rod is set in the oil distribution shaft, and the oil distribution shaft is set in the casing. When the oil distributor is working, hydraulic oil is injected into the oil distribution shaft through the oil injection port on the oil distributor, and the oil distribution shaft has an axially arranged shaft hole, and the shaft hole is used to transmit hydraulic oil. Therefore, the hydrau...

Abstract
The invention provides an assembling method of a controllable-pitch propeller oil distributor. The assembling method comprises the steps that a plurality of slings are connected to the oil distributor, and the slings are used for applying acting forces in a first direction, a second direction and a third direction to the oil distributor; the slings are controlled to apply the acting force in the first direction to the oil distributor, and concentricity of a valve core rod of the oil distributor and an oil pipe of a gearbox is adjusted; the oil pipe is connected with the valve core rod and thegearbox; the slings are controlled to apply the acting force in the third direction to the oil distributor, and an oil distribution shaft and an output shaft of the gearbox are connected; a bounce degree of a first end of the oil distributor is checked; if the bounce degree is detected to be qualified, the slings are controlled to apply the acting force in the second direction to the oil distributor, and anti-loosening treatment is performed on a fastener connected with the oil distribution shaft and the output shaft of the gear box; and the slings are controlled to apply the acting force in the third direction to the oil distributor, and the shell of the oil distributor and the shell of the gearbox are connected. Assembling work of the oil distributor can be rapidly completed, and assembling work efficiency of the oil distributor is improved.
Description
technical field [0001] The present disclosure relates to the technical field of controllable pitch propellers, in particular to an assembly method of an oil distributor of a controllable pitch propeller. Background technique [0002] Controlled pitch propeller is a form of ship propulsion widely used at present. More and more ships use controllable pitch propeller as propulsion device. Controlled pitch propeller is distributed in each cabin of the ship. Change the ship's course speed. The oil distributor is an important part of the controllable pitch propeller. When the oil distributor is working, the hydraulic oil will be sent into the variable pitch cylinder of the controllable pitch propeller through the oil distribution shaft of the oil distributor to push the piston in the variable pitch cylinder to reciprocate The movement realizes pitch change of the pitch control propeller in front or reverse. In addition, there are strict requirements on the positioning and instal...
