Technical Field
The utility model relates to a paddle pitch feedback mechanism of controllable pitch oar belongs to marine propeller field.
Background
In the field of marine propellers, the pitch control propeller device needs a pitch feedback mechanism of blades so as to be convenient for sailors, debugging and maintenance personnel and the like to know the pitch condition of the blades of the underwater propeller. In the controllable pitch propeller device, the distance between the propeller blade and the feedback display is long, the path is complex, and the internal space is limited, so the design of the propeller blade pitch feedback mechanism is complex.
Therefore, the pitch feedback mechanism of the controllable-pitch propeller blade, which has reliable function, higher precision, sensitive feedback and reasonable layout, is designed and is very important for the controllable-pitch propeller device; the traditional pitch feedback mechanism adopts chain wheel and chain transmission, the feedback precision is relatively low, and the space required by the feedback mechanism is large.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art and providing a feedback precision is higher, paddle pitch feedback mechanism that occupation space is less.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a blade pitch feedback mechanism comprises a bearing seat assembly, a connecting plate assembly, a connecting frame, a long feedback rod, a supporting seat and a short feedback rod; the connecting frame is hinged to the connecting plate assembly, the hinged position serves as a rotating fulcrum of the connecting frame, one end of the connecting frame is connected with the bearing seat assembly, the other end of the connecting frame is hinged to the long feedback rod, the other end of the long feedback rod is hinged to the short feedback rod, and the short feedback rod penetrates through the supporting seat.
Preferably, the bearing housing assembly comprises a bearing housing and a bearing.
Preferably, the bearing seat assembly is hinged to the connecting frame through a lower joint.
Preferably, the connecting frame is an L-shaped connecting plate.
Preferably, the two ends of the long feedback rod are provided with the switching joints, and the long feedback rod is hinged with the connecting frame and the short feedback rod through the switching joints at the two ends respectively.
Preferably, the long feedback rod is matched with the switching joints at two ends through a thread structure.
Preferably, the support seat radially limits the short feedback rod, so that the short feedback rod axially reciprocates.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
according to the scheme, the change of the pitch is fed back through the lever mechanism, the layout is more compact in space, and the feedback precision of the pitch of the paddle is higher; the connecting frame can adopt a right-angle structure, so that the transmission direction of the screw pitch is skillfully changed, and the space is further saved; the joint connection form of the bearing seat assembly and the connecting frame enables the space freedom degree of the bearing seat assembly to be properly released and restrained, and the operation flexibility of the whole mechanism is well guaranteed.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
fig. 1 is a schematic structural diagram of a blade pitch feedback mechanism according to the present invention;
fig. 2 is a front view of a blade pitch feedback mechanism according to the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, the blade pitch feedback mechanism of the present invention comprises a bearing housing assembly 1, a connecting plate assembly 2, a connecting frame 3, a long feedback rod 5, a supporting seat 6 and a short feedback rod 7; the connecting frame 3 is hinged to the connecting plate assembly 2, the hinged position serves as a rotating fulcrum of the connecting frame 3, one end of the connecting frame 3 is connected with the bearing seat assembly 1, the other end of the connecting frame is hinged to the long feedback rod 5, the other end of the long feedback rod 5 is hinged to the short feedback rod 7, and the short feedback rod 7 penetrates through the supporting seat 6.
The bearing seat assembly 1 comprises a bearing seat and a bearing 8, the bearing 8 can be a double-row bearing, the connecting frame 3 is an L-shaped connecting plate, the bearing seat assembly 1 is hinged to the connecting frame 3 through a lower joint 9, the two ends of the long feedback rod 5 are both provided with the switching joints 4, the long feedback rod 5 is respectively hinged to the connecting frame 3 and the short feedback rod 7 through the switching joints 4 at the two ends, and the long feedback rod 5 is matched with the switching joints 4 at the two ends through a threaded structure, so that the long feedback rod 5 serving as a quick-wear part is convenient to replace; the supporting seat 6 radially limits the short feedback rod 7, so that the short feedback rod 7 axially reciprocates.
When the variable-pitch propeller works, the blade pitch adjustment of the variable-pitch propeller is realized by the reciprocating motion of a piston rod in a pitch adjustment oil cylinder, when the piston rod moves towards the direction indicated by an arrow in figure 1, an oil distribution rod component drives a bearing seat component 1 to move towards the left side, and a connecting frame 3 rotates clockwise through a connecting plate component 2 serving as a fulcrum to drive a long feedback rod 5 to swing upwards; the long feedback rod 5 drives the short feedback rod 7 to vertically move upwards, and the support seat 6 radially restrains the short feedback rod 7; finally, the pitch change of the propeller blades can be transmitted to a dial plate of a feedback device in the water surface cabin for displaying.
When the paddle rotates in the opposite direction, the components move in the opposite direction of the arrow shown in the figure.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
