Abstract
A feedback device applied to a feathering structure mainly comprises an outer pipe flange, an inner oil pipe, a spring, a spring seat and a blocking ring. The outer pipe flange is fixed on a propeller shaft of a propeller hub through bolts, the spring is clamped together with the spring seat through a outer pipe inner cavity boss in the middle, the blocking ring is fixed on the inner oil pipe through a groove formed in the outer wall of the inner oil pipe, the left side of the spring seat is limited on the outer wall of the inner oil pipe through the blocking ring, and the inner oil pipe is capable of moving left and right along a guide frame. The feedback device applied to the feathering structure has the advantages of being simple and compact in structure, reliable in performance, and capable of saving energy and being used matched with an ordinary outer diameter (OD) box, and facilitating standardized production and the like.
Description
Technical field
The utility model relates to a kind of positioner that is applied to marine propeller propeller hub inside configuration, be applicable to feathering propeller hub structure.
Background technology
In the prior art, because the stroke of feathering approximately is 2 times of conventional adjustable propeller, and the stroke of common feedback system requirement OD case also approximately is 2 times of conventional OD case.This spline structure is compact not, causes waste of material, also is unfavorable for the standardized production of product.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of the conventional OD case of configuration to get final product, compact conformation, and reliability is high, is beneficial to the positioner that is applied to feathering propeller hub structure of standardized production.
The purpose of this utility model is finished by following technical solution, it is mainly by outer pipe flange, inner oil tube, spring, spring perch, back-up ring forms, described outer pipe flange is bolted on the oar axle of propeller hub, and spring is clipped in the middle by outer pipe flange inner chamber boss and spring perch, and back-up ring is fixed on the inner oil tube by the trough of offering on the inner oil tube outer wall, spring perch passes on left retainer ring spacing on the inner oil tube outer wall, and inner oil tube can be along the saddle sway.
The utility model can be mobile from left to right by spring and saddle, realizes successively feathering, and positive car stops, four operating modes of moveing backward, and when realizing reversing, parking, ahead condition, inner oil tube is moved to the left, and forms feedback; When realizing the ahead running operating mode, spacing by inner oil tube high order end or inner oil tube outer wall upper flange.
The utlity model has simple and compact for structurely, dependable performance can be saved cost, and the conventional OD case of configuration gets final product, and is beneficial to the characteristics such as standardized production.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Label shown in the figure is: 1 propeller hub body, 2 saddles, 3 blade seats, 4 blades, 5 slide blocks, 6 blade bolts, 7 blind flanges, 8 bolt with flanges, 9 oar axles, 10 outer oil pipes, 11 inner oil tubes, 12 outer pipe flanges, 13 springs, 14 spring perches, 15 back-up rings.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.Shown in Figure 1 mainly by outer pipe flange 12, inner oil tube 11, spring 13, spring perch 14, back-up ring 15 forms, and described outer pipe flange 12 is bolted on the oar axle 9 of propeller hub, spring 13 is clipped in the middle by outer pipe flange 12 inner chamber boss and spring perch 14, back-up ring 15 is fixed on the inner oil tube by the trough of offering on inner oil tube 11 outer walls, and it is spacing on inner oil tube 11 outer walls that spring perch 14 passes on left back-up ring 15, and inner oil tube 11 can be along saddle 2 sway.
The utility model can be mobile from left to right by spring and saddle, realizes successively feathering, and positive car stops, four operating modes of moveing backward, and when realizing reversing, parking, ahead condition, inner oil tube is moved to the left, and forms feedback; When realizing the ahead running operating mode, spacing by inner oil tube high order end or inner oil tube outer wall upper flange.
Working process of the present utility model is:
A) positive car-parking-reversing:
When hydraulic oil enters left oil pocket by inner oil tube 11, saddle 2 begins to move to right, hydraulic oil in the right oil pocket begins to return, saddle 2 moves to right and is with movable slider 5 to move to right, slide block 5 drives 3 rotations of blade seat by the trough of blade seat 3 bottoms, blade seat 3 and blade 4 are fixing by blade bolt 6, thereby make blade 4 rotate to set angle.Blade 4 rotates the purpose that has reached roll adjustment, has realized the positive car of boats and ships, stops and stops.Inner oil tube 11 moves together and Compress Spring 13 reaches conventional feedback stroke thereby the process that saddle moves to right drives by back-up ring 15.
B) reversing-stop-positive car
When hydraulic oil enters right oil pocket by outer oil pipe 10, saddle 2 begins to move to left, hydraulic oil in the left oil pocket begins to return, saddle 2 moves to left and is with movable slider 5 to move to left, slide block 5 drives 3 rotations of blade seat by the trough of blade seat 3 bottoms, blade seat 3 and blade 4 are fixing by blade bolt 6, thereby make blade 4 rotate to set angle.Blade 4 rotates the purpose that has reached roll adjustment, has realized the reversing of boats and ships, stops and positive car.Saddle 2 begins to move to right, because spring 13 has been compressive state, meeting moves to right along with saddle and returns to gradually drift, and promotes spring perch 14 and back-up ring 15, so that inner oil tube 11 is moved to the left with saddle 2, feeds back stroke thereby reach routine.
C) positive car-feathering:
When hydraulic oil enters right oil pocket by outer oil pipe 10, saddle 2 begins to move to left, hydraulic oil in the left oil pocket begins to return, saddle 2 moves to left and is with movable slider 5 to move to left, slide block 5 drives 3 rotations of blade seat by the trough of blade seat 3 bottoms, blade seat 3 and blade 4 are fixing by blade bolt 6, thereby make blade 4 rotate to set angle.Blade 4 rotates the purpose that has reached roll adjustment, has realized positive car and the feathering of boats and ships.This process can not produce thrust to spring perch because spring 13 has been the drift state, so inner oil tube 11 stagnations are motionless, when saddle 2 arrival propeller hubs 1 top, pressure can increase rapidly, feeds back this Working pasition by pressure setting, i.e. the feathering operating mode.
D) feathering-positive car:
When hydraulic oil enters left oil pocket by inner oil tube 11, saddle 2 begins to move to right, hydraulic oil in the right oil pocket begins to return, saddle 2 moves to right and is with movable slider 5 to move to right, slide block 5 drives 3 rotations of blade seat by the trough of blade seat 3 bottoms, blade seat 3 and blade 4 are fixing by blade bolt 6, thereby make blade 4 rotate to set angle.Blade 4 rotates the purpose that has reached roll adjustment, has realized feathering and the positive car of boats and ships.This process saddle 2 can not contact with spring 13, so inner oil tube 11 is to stagnate motionlessly, when saddle 2 moves to right when 15 contacts, just can force spring 13 compressions to realize feeding back.
