Description
Technical field
The present invention relates to a kind of light-duty sport plane tensile test platform, especially a kind of novel propeller tensile test bench for light sport aircraft, belongs to field of aerospace technology.
Background technology
Along with the development of global general-use Aerobiz, the development of new model light aerocraft is also more increasing with day, and new model aircraft is before first-fly, and aircraft power system performance parameter is indispensable.The cruise speed of light-duty sport plane is not high, therefore the rotating ratio of its engine is lower, and pulling force is also smaller, reduces the frictional dissipation between parts in this case and provides testing table to be accurately crucial.Torque sensor can be directly connected to above output shaft by shaft coupling by the method for torque measurement, and tension measurement will consider problem more.The complex structure of existing tensile test platform, test operation is also cumbersome.Because the result of its test of structural reason is also not accurate enough.
Summary of the invention
The present invention is directed to the complex structure that above-mentioned prior art exists, the problem that precision is low and cost is high, and the propeller tensile test bench for light sport aircraft of a kind of high precision, low cost is provided, solve existing light aerocraft power system test operation complicated, be difficult to the problem obtaining accurate result.
For achieving the above object, the technical solution used in the present invention is: propeller tensile test bench for light sport aircraft, comprise lower mounting bracket (1) and upper mounting bracket (2), upper mounting bracket (2) is fixed with apical axis bearing seat (16) by top braces (17), 4 connecting rod (18) upper ends are fixed on upper mounting bracket (2) by connecting rod arm (10) and the bearing in apical axis bearing seat (16), and connecting rod lower end is fixed on boatswain chair (19) by boatswain chair bearing (15).Screw propeller mounting flange (14) and extension shaft (13) are mechanically connected, extension shaft (13) is provided with successively fixed hub (12), rear end shaft coupling (11), torque sensor (9), spring coupling (8), spring coupling (8) connects tested motor (7), tested motor (7) by rear fixed mounting (5) and mount pad connecting bottom board (6) and by coupling bolt (4) fix.Boatswain chair (19) rear end is connected on mounting bracket (2) by pulling force sensor (3).Thus the pulling force that screw propeller rotary motion produces is delivered on pulling force sensor out tested by boatswain chair-four-bar mechanism, moment of torsion is then obtained by torque sensor test.Undertaken reading or record by corresponding Displaying Meter again.
Principle of work: according to the principle of double leval jib Forced rotation, motor helical oarage is sling, screw propeller produces pulling force when the engine is started, equipment relies on four bearings to rotate, because displacement is very little, so can think that equipment moves in parallel, the pulling force of screw propeller so just can be measured.Torque sensor is arranged between screw propeller and motor, then they is coupled together with spring coupling and high strength bearing.Advantage is that structure is simple and clear, and cost is low, is applicable to the test of put-put and screw propeller.
Beneficial effect of the present invention and feature: compared with prior art the structure of double leval jib arm scheme is more succinct, and only need bearing and connecting rod to connect, the low measuring accuracy of cost is also higher.Use this complete equipment, the test of engines ground rotary speed property, the test of screw propeller ground rotary speed property, the test of propulsion system ground rotary speed property can be carried out.During simple research engine performance, screw propeller only does load, changes the pitch that load only need be changed screw propeller or change screw propeller; During simple research propeller performance, engine is then only as the power driving screw propeller.Put this covering device into wind-tunnel, propeller speed characteristic and propulsion system speed characteristic test can be carried out; This covering device is moved to the highlands of different altitude height, the test of propulsion system altitude response can be carried out.The present invention, compared with other light aerocraft propeller tensile test stand, has test period short, simple to operate, the more high series of advantages of measuring accuracy.

With reference to Fig. 1-3, propeller tensile test bench for light sport aircraft, comprise lower mounting bracket 1 and upper mounting bracket 2, upper mounting bracket 2 is fixed with apical axis bearing seat 16 by top braces 17,4 connecting rod 18 upper ends are fixed on upper mounting bracket 2 by connecting rod arm 10 and the bearing in apical axis bearing seat 16, and connecting rod lower end is fixed on boatswain chair 19 by boatswain chair bearing 15.Screw propeller mounting flange 14 and extension shaft 13 are mechanically connected, extension shaft 13 is provided with successively fixed hub 12, rear end shaft coupling 11, torque sensor 9, spring coupling 8, spring coupling 8 connects tested motor 7, and tested motor 7 is by rear fixed mounting 5 and mount pad connecting bottom board 6 and fixed by coupling bolt 4.Boatswain chair 19 rear end is connected on upper mounting bracket 2 by pulling force sensor 3.Thus the pulling force that screw propeller rotary motion produces is delivered on pulling force sensor out tested by boatswain chair-four-bar mechanism, moment of torsion is then obtained by torque sensor test.Undertaken reading or record by corresponding Displaying Meter again.
During work, after tested motor 7 starts running, the moment of torsion that its rotation produces and rotating speed are measured by torque sensor 9 and are drawn, it moves through drive shaft system (elasticity shaft joint 8, rear end shaft joint 11, extension shaft 13) be delivered to screw propeller mounting flange 14 thus carrying screws rotation, propeller rotational produces pulling force forward, drive boatswain chair 18 to produce small translation forward around boatswain chair bearing 15, this trend is measured by pulling force sensor 3 and is drawn.The rotating speed recorded according to motor operation, moment of torsion can calculate its power.
Main testing tool used in test, except the routine measurement instrument such as rotating speed, temperature, voltage that engine work needs, also have two specific apparatus: 1. tension tester and pulling force sensor supporting, the pulling force of screw propeller can be measured, namely the pulling force of whole propulsion system; 2. torque rotational speed meter and torque rotary speed sensor supporting, the rotating speed of screw propeller, input torque and power can be measured, namely the output power of engine.Data, except Real-time Collection, display, can also store and print by this instrument.
