Abstract
The utility model discloses a novel blade static balance detector, comprising a workbench, an X-shaft and a Y-shaft on the workbench. The two ends of the X-shaft are equipped with bearings, so that the circumferential direction of the X-shaft is not applied with forces to be restrained; one end of the X-shaft is connected with a torque sensor via a shaft coupling, and the other end of the torque sensor is fixed on an anti-rotating bracket, so that an X-directional moment detection system is formed. The structure of a Y-directional moment detection system is similar to that of the X-directional moment detection system, the difference is that one end of the Y-shaft is equipped with an adapter disc used for assembling a tested blade. The whole Y-directional detection system is assembled on a Y-shaft bracket, and the Y-shaft bracket is locked on the X-shaft to prevent rotation. The moment sensors in the X and Y directions are both connected with a display, and the moment measurement values in the two directions can be read out visually via the display. By using the novel blade static balance detector, the disadvantage that a special detecting device is not existed in the prior art, and the problems that the conventional algorithm is complicated and not accurate, and the operation is not convenient, are solved.
Description
Technical field
The utility model relates to pick-up unit, specifically a kind of novel C PP blade static equilibrium detector.
Background technology
Variable-pitch propeller peculiar to vessel slurry (CPP) is assembled by 3～5 blades and slurry hub, and the pitch of blade can be regulated according to the navigation situation of boats and ships, makes propeller-main frame reach the optimum matching state, thereby reaches energy-conservation, purpose efficiently.
In each item technical parameter of propeller, the blade static equilibrium is an important techniques index.If propeller statical equilibrium is good, in use can make stern tube shaft produce alterante stress, cause the hull shake, can shorten the serviceable life of boats and ships simultaneously.
Concerning CPP, the weight of one group of blade and centre of gravity place must have the consistance of height, otherwise after blade was assembled on the propeller hub, the whole static equilibrium of screw propeller can not get guaranteeing.
Detecting CPP blade balance method commonly used at present both at home and abroad is pivot point technique or unidirectional force moments method.Above-mentioned two kinds of method precision are low, and computation process is complicated, inconvenient operation.
The utility model content
The technical matters that (one) will solve
The purpose of the utility model is the defective that exists to prior art, and novel C PP blade static equilibrium detector is provided, and has solved the drawback that do not have special pick-up unit in the prior art and the problem of traditional algorithm complicacy out of true, inconvenient operation.
(2) technical scheme
The utility model solves the technical scheme that its technical matters adopted: new blade static equilibrium detector, its structure comprise X on worktable, the worktable to axle and Y to axle; Said X places on the bearing seat on the worktable to axle; Said Y places on the bearing seat on the Y bracing strut to axle, and the Y bracing strut then is connected on the X axle.
Said X to axle wherein an end connect through shaft coupling and be arranged on the torque sensor on the anti-rotation support; Said Y to axle wherein an end also connect and be arranged on the torque sensor on the anti-rotation support through shaft coupling, Y then is connected with transfer panel to the axle other end.
(3) beneficial effect
A kind of new blade static equilibrium detector of the utility model is compared with prior art, has following beneficial effect:
Bearing is equipped with at directions X axle two ends, makes it circumferentially not have stressed constraint, and wherein an end connects with torque sensor through shaft coupling, and the torque sensor other end is fixed on the anti-rotation support, thereby constitutes X to the moment detection system; To similar, difference is that Y axle one end is equipped with transfer panel, is used to assemble blade to be tested to Y to moment detection system structure and X.Whole Y is assemblied on the Y bracing strut to test macro, and the Y bracing strut is locked in and prevents on the X axle to rotate.The torque sensor of X, Y both direction all is connected with display, can read the torgue measurement value of both direction intuitively through display.

Embodiment
Next explanation at length below with reference to Figure of description a kind of new blade static equilibrium detector of the utility model being done.
A kind of new blade static equilibrium detector, its structure comprise X on worktable 1, the worktable to axle 2 and Y to axle 7; Said X places on the bearing seat 3 on the worktable to axle; Said Y places on the bearing seat 8 on the Y bracing strut 12 to axle, and the Y bracing strut then is connected on the X axle.
Said X to axle wherein an end connect through shaft coupling 4 and be arranged on the torque sensor 5 on the anti-rotation support 6; Said Y to axle wherein an end also connect and be arranged on the torque sensor 10 on the anti-rotation support 11 through shaft coupling 9, Y then is connected with transfer panel 13 to the axle other end.
The principle of this pick-up unit: measure the moment of torsion (be moment) of blade to X axle and Y axle respectively, M=f * L gets according to the moment formula: Lx=Mx/G, thereby Ly=My/G obtain blade center-of-gravity station (Lx, Ly)
Wherein: the G----leaf weight
The Lx----blade center of gravity is apart from the distance of X axle
The Mx---blade is to the moment of X axle
The Ly----blade center of gravity is apart from the distance of Y axle
The Mx---blade is to the moment of Y axle.
Bearing is equipped with at directions X axle two ends, makes it circumferentially not have stressed constraint, and wherein an end connects with torque sensor through shaft coupling, and the torque sensor other end is fixed on the anti-rotation support, thereby constitutes X to the moment detection system; To similar, difference is that Y axle one end is equipped with transfer panel, is used to assemble blade to be tested to Y to moment detection system structure and X.Whole Y is assemblied on the Y bracing strut to test macro, and the Y bracing strut is locked in and prevents on the X axle to rotate.The torque sensor of X, Y both direction all is connected with display, can read the torgue measurement value of both direction intuitively through display.
The above embodiment is a kind of of the more preferably concrete embodiment of the utility model, and common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included in the protection domain of the utility model.
