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...

The present disclosure provides an assembly method of an oil distributor for a controllable pitch propeller. The assembly method includes: connecting a plurality of slings to the oil distributor, and the plurality of slings are used to apply a first direction, a second The force in the first direction and the third direction; control the sling to apply the force in the first direction to the oil distributor, adjust the concentricity of the valve core rod of the oil distributor and the oil pipe of the gearbox; connect the valve core rod and the oil pipe of the gearbox ;Control the sling to apply a force in the third direction to the oil distributor, connect the oil distribution shaft and the output shaft of the gearbox; check the runout of the first end of the oil distributor; if the test is qualified, control the sling to The oil distributor applies force in the second direction, and the fasteners connecting the oil distribution shaft and the output shaft of the gearbox are anti-loosening; the control sling applies force in the third direction to the oil distributor, and the oil distributor is connected The casing and the casing of the gearbox. The disclosure can quickly complete the assembly operation of the oil distributor, and improve the assembly operation efficiency of the oil distributor.
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...
