Description
Technical field
The present invention relates to a kind ofly to can be used for that boats and ships are promoted mainly into, the boats and ships of thruster, full circle swinging oar are with integral structure formula propeller hub, belong to ship propeller tuning for Controllable Pitch Propeller technical field.
Background technology
Propeller hub is one of core component of pitch propeller device, and it is the load bearing component of tractive power, is again the final actuating unit of roll adjustment, and therefore, the reliability of propeller hub is most important.In the existing propeller hub, general saddle front end inserts the oil cylinder of propeller hub front end, the protruding weir of the closed loop sliding block joint of its outer wall and oil cylinder entrance, the rear end of the end insertion saddle of stern tube shaft, between be equipped with the lining oil sealing.The propeller hub of this structure, because many two lining oil sealings, and itself have sealing problem between lining and propeller hub oil cylinder, lining and the saddle, and when work, slide before and after the saddle, and oil pressure to be higher, this just causes leaking at the lining place easily.On the other hand, propeller hub body and lining adhere to two parts separately, are separate machined, and the eccentric error that this will cause between saddle after the assembling and lining causes two parts stuck mutually, influences the operation of mechanism, also can bring very big leakage phenomenon simultaneously.
In the existing propeller hub; Saddle front end outer wall and back end inside diameter appearance not of uniform size; This structure makes the ahead running oil pocket little with respect to the piston stress area of reversing oil pocket, and the relative rotation of blade and propeller hub is constant when guaranteeing the screw propeller rotation, and acting on two power on the oil pocket piston must the maintenance balance; Therefore, the working oil pressure of ahead running oil pocket is much larger than the pressure of reversing oil pocket; After pressure improved, not only the intensity to corresponding part proposed higher requirement, and increased the risk of hydraulic system leakage.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, and a kind of higher strength and stiffness that have are provided, whole processing; Not only convenient; And have better right alignment, operation is steady more, reliable, and the boats and ships of good seal performance are with integral structure formula propeller hub.
The objective of the invention is to realize like this: it mainly is made up of propeller hub body, saddle, slide block, blade seat, oar axle, and described propeller hub body and cylinder body integrate, and the front end of propeller hub body is connected with said oar axle with the high strength bolt with flange; Be provided with movably saddle in the described propeller hub body, this saddle and piston integrate, and its front end is as the oil cylinder of an oil pocket, and the rear end is as the piston of another oil pocket, and its front inner diameter and rear end external diameter equal and opposite in direction, have guaranteed that the ahead running operating oil pressure is consistent; Described oar axle is enclosed in the saddle front end, pack into the rear portion of propeller hub body, saddle rear end, and said saddle middle part outer wall is provided with the chute that slide block is installed, and described slide block set is on the crank pin that said blade seat disk root is provided with; Said slide block and crank pin and chute flexibly connect.
The dividing plate that described saddle middle part is provided with makes it be divided into two chambers, and saddle front inner wall and oar shaft end chamber form front chamber, and saddle rear end and propeller hub body oil cylinder form rear chamber; One outer oil pipe is loaded on the oar axle and is communicated with front chamber; One inner oil tube is communicated with rear chamber, and can move with saddle.
Be provided with guide ring between said saddle front inner wall and the oar axle external diameter; Also be provided with guide ring between saddle rear end outer radius and the propeller hub body inwall.
The invention has the advantages that: propeller hub body and rear end oil cylinder integrate, and have higher strength and stiffness, and whole processing is not only convenient, and has better right alignment; Saddle and piston integrate, and have improved stiffness of structural member and intensity, and saddle inwall and oar axle outer wall are through the guide ring sliding support, and operation more steadily, reliably; Be provided with combined seal ring between oil cylinder and the piston, the sealing circle has the compensate for wear effect, has improved sealing property; Saddle rear end outer wall is identical with leading portion inner diameter size, and area is bigger, and the ahead running operating oil pressure equates, greatly reduces the requirement of parts intensity, has also improved the reliability of hydraulic efficiency pressure system and sealing property simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Label among the figure is: 1, propeller hub body, 2, saddle, 3, blade, 4, slide block, 5, the blade seat, 6, the oar axle, 7, outer oil pipe, 8, the oar shaft-cup, 9, inner oil tube, 10, guide ring, 11,13 compound seals, 12, front chamber, 14, rear chamber.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further description.Shown in Figure 1, the present invention mainly is made up of propeller hub body 1, saddle 2, slide block 4, blade seat 5, oar axle 6, and described propeller hub body 1 integrates with cylinder body, and the front end of propeller hub body 1 is connected with said oar axle 6 with the high strength bolt with flange; Be provided with movably saddle 2 in the described propeller hub body 1, this saddle 2 integrates with piston, and its front end is as the oil cylinder of an oil pocket, and the rear end is as the piston of another oil pocket, and its front inner diameter and rear end external diameter equal and opposite in direction; Described oar axle 6 is enclosed in the saddle front end, pack into the rear portion of propeller hub body, saddle rear end, and said saddle 2 middle part outer walls are provided with the chute that slide block 4 is installed, and described slide block 4 is enclosed within on the crank pin that said blade seat 5 disk roots are provided with; Said slide block 4 flexibly connects with crank pin and chute.
The dividing plate that described saddle 2 middle parts are provided with makes it be divided into two chambers, and saddle 2 front inner wall and oar axle 6 end chambers form front chamber 12, and saddle 2 rear ends and propeller hub body 1 oil cylinder form rear chamber 14; One outer oil pipe 7 is loaded on the oar axle 6 and is communicated with front chamber 12; One inner oil tube 9 is communicated with rear chamber 14, and can move with saddle.
Be provided with guide ring 10 between said saddle 2 front inner wall and oar axle 6 external diameters; Also be provided with guide ring between saddle 2 rear end outer radius and propeller hub body 1 inwall.
The present invention is work like this in the practical implementation process: when hydraulic oil gets into rear chamber 14 through inner oil tube 9 (also can be referred to as interior duct member); Promote saddle 2 and move right, the hydraulic oil of front chamber 12 returns through outer oil pipe 7 (also can be referred to as the outer tube parts) circulation; When hydraulic oil gets into front chamber 12 through outer oil pipe 7, promote saddle 2 to left movement, the hydraulic oil of rear chamber 14 returns through inner oil tube 9 circulations.When saddle 2 is reciprocating along axis; Chute on the outer wall of center promotes slide block 4 and in groove, slides; Crank pin on the blade seat 5 disk roots is inserted in and drives blade seat 5 rotation together on the slide block 4; Blade 3 is fixedly mounted on the blade seat 5, and the rotation of blade seat 5 drives the angle change of blade 3, realizes the change of blade pitch.
