The invention provides a feedback device applicable to a feathering structure. The feedback device mainly comprises an external pipe flange, an internal oil pipe, a spring, a spring seat and a retainer ring, wherein the external pipe flange is fixed on an oar shaft of an oar hub by virtue of a bolt; the spring is clamped between a boss of an internal chamber of the external pipe flange and the spring seat; the retainer ring is fixed on the internal oil pipe by virtue of a groove formed on the external wall of the internal oil pipe; the left side of the spring seat is limited on the external wall of the internal oil pipe by virtue of the retainer ring; and the internal oil pipe can be moved to the left and right along a guide frame. The feedback device disclosed by the invention has the advantages of being simple and compact in structure and reliable in performance, saving the cost, only requiring a common OD box, being beneficial to standardized production, and the like.
Description
Technical field
What the present invention relates to is a kind of positioner that is applied to marine propeller propeller hub inside configuration, is applicable to feathering propeller hub structure.
Background technology
In the prior art, because the stroke of feathering is 2 times of conventional adjustable oar approximately, and the stroke of common feedback system requirement OD case also is 2 times of conventional OD case approximately.This spline structure is compact inadequately, causes waste of material, also is unfavorable for the standardized production of product.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, and provide a kind of the conventional OD case of configuration to get final product, compact conformation, reliability is high, is beneficial to the positioner that is applied to feathering propeller hub structure of standardized production.
The objective of the invention is to accomplish through following technical scheme, it is mainly by outer pipe flange, inner oil tube; Spring, spring perch, back-up ring is formed; Described outer pipe flange is through on the oar axle that is bolted to propeller hub, and spring is clipped in the middle through outer pipe flange inner chamber boss and spring perch, and back-up ring is fixed on the inner oil tube through the trough of offering on the inner oil tube outer wall; It is spacing on the inner oil tube outer wall that spring perch passes on left back-up ring, and inner oil tube can be along the saddle sway.
The present invention can move through spring and saddle from left to right, realizes feathering successively, 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 through inner oil tube high order end or inner oil tube outer wall upper flange.
The present invention has simple and compact for structure, and dependable performance can be practiced thrift cost, and the conventional OD case of configuration gets final product, and is beneficial to characteristics such as standardized production.
Description of drawings
Fig. 1 is a structural representation of the present invention.
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 present invention is done further description.Shown in Figure 1 mainly by outer pipe flange 12, inner oil tube 11, spring 13; Spring perch 14, back-up ring 15 is formed, and described outer pipe flange 12 is through on the oar axle 9 that is bolted to propeller hub; Spring 13 is clipped in the middle through outer pipe flange 12 inner chamber boss and spring perch 14; Back-up ring 15 is fixed on the inner oil tube through 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 present invention can move through spring and saddle from left to right, realizes feathering successively, 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 through inner oil tube high order end or inner oil tube outer wall upper flange.
Working process of the present invention is:
A) positive car-parking-reversing:
When hydraulic oil gets into left oil pocket through inner oil tube 11; Saddle 2 begins to move to right; Hydraulic oil in the right oil pocket begins to return, and saddle 2 moves to right and drives slide block 5 and move to right, and slide block 5 drives 3 rotations of blade seat through the trough of blade seat 3 bottoms; Blade seat 3 is fixing through blade bolt 6 with blade 4, thereby makes 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 compression spring 13 reaches conventional feedback stroke thereby the process that saddle moves to right drives through back-up ring 15.
B) reversing-parking-positive car
When hydraulic oil gets into right oil pocket through outer oil pipe 10; Saddle 2 begins to move to left; The hydraulic oil of a left side in the oil pocket begins to return, and saddle 2 moves to left and drives slide block 5 and move to left, and slide block 5 drives 3 rotations of blade seat through the trough of blade seat 3 bottoms; Blade seat 3 is fixing through blade bolt 6 with blade 4, thereby makes 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 drift gradually, and promotes spring perch 14 and back-up ring 15, makes inner oil tube 11 be moved to the left with saddle 2, thereby reaches conventional feedback stroke.
C) positive car-feathering:
When hydraulic oil gets into right oil pocket through outer oil pipe 10; Saddle 2 begins to move to left; The hydraulic oil of a left side in the oil pocket begins to return, and saddle 2 moves to left and drives slide block 5 and move to left, and slide block 5 drives 3 rotations of blade seat through the trough of blade seat 3 bottoms; Blade seat 3 is fixing through blade bolt 6 with blade 4, thereby makes blade 4 rotate to set angle.Blade 4 rotates the purpose that has reached roll adjustment, has realized the 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 operating mode position, i.e. feathering operating mode through the pressure setting.
D) feathering-positive car:
When hydraulic oil gets into left oil pocket through inner oil tube 11; Saddle 2 begins to move to right; Hydraulic oil in the right oil pocket begins to return, and saddle 2 moves to right and drives slide block 5 and move to right, and slide block 5 drives 3 rotations of blade seat through the trough of blade seat 3 bottoms; Blade seat 3 is fixing through blade bolt 6 with blade 4, thereby makes blade 4 rotate to set angle.Blade 4 rotates the purpose that has reached roll adjustment, has realized the feathering and 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.
