Abstract
A propeller tensile test bench for a light sport aircraft mainly solves the problems that an existing propeller tensile test bench is complex in structure, low in accuracy and high in cost in the prior art. The propeller tensile test bench comprises a lower mounting bracket and an upper mounting bracket; the upper mounting bracket is fixedly provided with a top shaft bearing block through a top support; the upper ends of four connecting rods are fixed on the upper mounting bracket through connecting rod lazy arms and bearings in the top shaft bearing block, and the lower ends of the connecting rods are fixed on a hanging plate through a hanging plate bearing. A propeller mounting flange is in mechanical connection with a lengthened shaft. The rear end of the hanging plate is connected to the upper mounting bracket through a tension sensor. Therefore, tensile force produced by the rotational motion of the propeller is transmitted to the tension sensor through a hanging plate and four connecting rod mechanism and is tested out, and torque is tested and obtained through a toque sensor. Then, reading or recording is performed through corresponding display meters. Compared with similar products, the propeller tensile test bench has the advantages of being short in testing cycle, easy to operate, high in testing accuracy and the like.
Description
Technical field
The present invention relates to a kind of light-duty sport plane tensile test platform, especially a kind of novel light-duty sport plane screw propeller tensile test platform, 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, pulling force is also smaller, and it is crucial reducing in this case the frictional dissipation between parts and testing table is accurately provided.The method of torque measurement can directly be connected to torque sensor above output shaft by shaft coupling, and tension measurement will be considered problem more.The complex structure of existing tensile test platform, test operation is also cumbersome.Because the result of structural its test of reason is also not accurate enough.
Summary of the invention
The present invention is directed to the problem that complex structure, precision are low and cost is high that above-mentioned prior art exists, and provide a kind of high precision, light-duty sport plane screw propeller tensile test platform cheaply, solve existing light aerocraft power system test operation complicated, be difficult to obtain the problem of accurate result.
For achieving the above object, the technical solution used in the present invention is: light-duty sport plane screw propeller tensile test platform, 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 rods (18) upper end is fixed on upper mounting bracket (2) above 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) mechanical connection, fixed hub (12), rear end shaft coupling (11), torque sensor (9), spring coupling (8) are installed on extension shaft (13) successively, spring coupling (8) connects tested motor (7), and tested motor (7) is by rear fixed mounting (5) and mount pad connecting bottom board (6) fixing by coupling bolt (4).Boatswain chair (19) rear end is connected on upper mounting bracket (2) by pulling force sensor (3).Thereby screw propeller rotatablely moves, the pulling force that produces is delivered on pulling force sensor out testedly by boatswain chair-four-bar mechanism, and moment of torsion is obtained by torque sensor test.By corresponding Displaying Meter, read or record again.
Principle of work: according to the principle of the stressed rotation of four connecting rods, motor screw propeller equipment is sling, when engine start, screw propeller produces pulling force, equipment relies on four bearings to rotate, because displacement is very little, so can think that equipment is parallel, so just can measure the pulling force of screw propeller.Torque sensor is arranged between screw propeller and motor, then with spring coupling and high strength bearing, they is coupled together.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 four connecting rod arm schemes is more succinct, only need bearing and connecting rod to connect, and the low measuring accuracy of cost is also higher.Use this complete equipment, can carry out 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.During simple research engine performance, screw propeller is only done load, changes the pitch that load only need be changed screw propeller or change screw propeller; During simple research propeller performance, engine is only as the power that drives screw propeller.Put this covering device into wind-tunnel, can carry out propeller speed characteristic and propulsion system speed characteristic test; This covering device is moved to the highlands of different altitude height, can be carried out the test of propulsion system altitude response.The present invention compares with other light aerocraft screw propeller tensile test stand, has short, simple to operate, the more high series of advantages of measuring accuracy of test period.
