Description
Multifunctional spiral oar resistance dynamometer belongs to propeller for vessels model hydrodynamic property proving installation.
For carrying out the research of object propulsion quality in boats and ships and the water,, wherein be used to test all kinds of propeller models and associated catheter models pushes away, the instrument of torsion is called resistance dynamometer usually by means of model test.It is the critical equipment of research screw propeller hydrodynamic property, and comparatively authoritative with the resistance dynamometer of West Germany Kempf-Remmers company (being called for short K﹠R company) production in the world at present, most of naval tanks are all ordered the instrument that they produce.
Resistance dynamometer generally only has one or two function, and carrying out dissimilar model-propeller testings need be with multi-form resistance dynamometer.Fig. 1 is the H29 single screw resistance dynamometer structural representation that K﹠R company produces, and it is made up of main body measure portion 1, supporting section 2, drive motor 3, revolution counter 4 and rail brackets 5 several sections.Drive motor by the bevel-gear sett in the main body measure portion 10 drive be loaded in the model propeller rotation of axle 6 terminations, it pushes away, torsion by push away, torque component 8 impressions, test through slip ring group 9 output signals.Central siphon 7 is connected with housing, plays a supportive role.The resistance dynamometer of this single shaft can only be measured the pushing away of single screw, torsion.
If carry out the test of counter rotating propeller model hydrodynamic performance, the R40 counter rotating propeller resistance dynamometer that then need use K﹠R company as shown in Figure 2 to produce, it is actually by the single screw resistance dynamometer 11 of a hollow shaft and solid axle single screw resistance dynamometer 12 direct connections and forms.The open water experiment that is used for screw propeller, very big spacious water tank 14 of face shield is installed drive motor 15 and right angle biography rotary device 13, and is fixed on the liftable guide rail 16 on casing outside, and structure is quite heavy.
H29 and R40 are the large-scale experiment instruments, but because function is single-minded, can not mutual alternative.The pump injection catheter resistance dynamometer that nineteen eighty-two 702 is developed though have the test function of single screw hydrodynamic performance concurrently, can not be used for the test of counter rotating propeller.
In addition, carry out the self-propulsion test of ship model, also need be with another from air power instrument (also title) from navigating instrument.For example corresponding with aforesaid H29, the R45 that single screw ship model self-propulsion test employing is then arranged is from the air power instrument, and its structural representation as shown in Figure 3.Its range is identical with H29, is actually " stamen " of H29 main body measure portion, adds a case and forms.During test, as shown in Figure 4, R45 18 is installed in the ship model, an end is connected with drive motor 17, and the other end is connected with axle system.In the axle system, screw shaft pipe 21 two ends respectively have a plain bearing 22 supporting tailing axle 20, and the pushing away of screw propeller, torsion are passed to resistance dynamometer by tailing axle through universal coupling 19 and tested.Each test all will be done installation again resistance dynamometer and axle system, and must strict guarantee resistance dynamometer axis and the screw propeller tailing axle be in straight line, otherwise can cause very big error.The replica test of the same ship model of same sometimes screw propeller fails to make two axial lines to overlap owing to install, and cause the different test results that are difficult to write, so that the ship model self-propelled test result can't analyze.
Therefore, indoor at a basin test, in order to satisfy the requirement of dissimilar screw propeller tests, often need to be equipped with many and can carry out open water experiment, the screw propeller resistance dynamometer that the self-propulsion test pairing is used is such as single screw open water experiment resistance dynamometer, single screw self-propulsion test resistance dynamometer, the screw propeller resistance dynamometer of single screw carrying pipe, counter rotating propeller resistance dynamometer, pump injection catheter resistance dynamometer or the like.This just causes maintenance to use inconvenience, the result that the instrument degree of utilization is extremely low.
The research of screw propeller propulsion mode is in continuous development in recent years, many new propellers that DEVELOPMENT PROSPECT arranged are anxious treats that corresponding resistance dynamometer tests, tandem propeller for example, if test with common resistance dynamometer, then can only record before and after two oars total push away, torsion, this considers influencing each other of front and back two oars to its performance of in-depth study, and is very not enough beyond doubt.Tandem propeller or counter rotating propeller add the propulsion mode of conduit for another example, are likely a kind of propelling unit that can satisfy specific (special) requirements.But common resistance dynamometer also can't be tested its performance.If, for Application and Development research, develop new resistance dynamometer again to these propulsion modes, the above-mentioned disadvantage that has existed is more worsened.
The purpose of this utility model is a kind of later-model resistance dynamometer of invention, makes it have following function:
1. the main body measure portion adopts biaxial system, the outer shaft setting can disconnect, compound and disconnect after be fixed in the structure of housing, the structure that is connected with outer shaft after interior axial cone gear is provided with and throws off and throw off, make the twin shaft can be to changeing, change in the same way, or the one axle is changeed or do not change, thereby the function of existing screw propeller resistance dynamometer is integrated in one.
2. utilize on the twin shaft separately independently load-sensing unit, when twin shaft rotates in the same way, carry out the hydrodynamic test respectively of two oars before and after the tandem propeller.
3. be tandem propeller, the hydrodynamic force test that counter rotating propeller adds the new propulsion mode of conduit provides possibility.
The utility model is made up of main body measure portion, supporting section, drive motor, revolution counter and rail brackets five parts, and wherein the main body measure portion is a core of the present utility model, and the H29 resistance dynamometer that remainder and West Germany K﹠R company produce mutually roughly the same.
Fig. 5 is a structural representation of the present utility model, the main body measure portion is provided with the biaxial system of coaxial line, outer shaft is a hollow shaft, interior axle center is for passing through lead, also make hollow shaft, drive motor 23 drives bevel gear set 28 by axle drive shaft 24 and rotates, this gear cluster is made up of three curved tooth conical tooth shafts, during the intermediate gear rotation, promptly driving former and later two gear mesh changes, again because outer shaft is to be connected with former and later two gears respectively with interior axle, therefore at the front and back of diaxon termination screw propeller 35 and 34 also thereupon to changeing, and will push away, torsion acts on respectively and is connected in pushing away on the axle, torque component 36 and 39, measurement signal can be respectively by slip ring group 27,30 spread out of, the measurement form of Here it is counter rotating propeller.Outer shaft 29, interior axle 26.
As shown in Figure 6, if earlier screw 41 is taken out, again sliding block joint axle 31 is shifted to a left side, thereby outer shaft is disconnected, (i.e. the position of dotted line among the figure), and be connected with housing 42 31, then outer shaft is not slew mode, antifriction-bearing box 32 is a fulcrum, and seal ring 33 keeps watertights, the test form of Here it is pump jet propeller.
Under the non-rotary situation of above-mentioned outer shaft, only screw propeller is installed at interior axle head head, outer shaft is only done as the pivot shaft pipe.If have conduit 37 to be connected, then can do the test that single screw or single screw add conduit with the conduit resistance dynamometer.
As shown in Figure 7, if the finishing bevel gear cuter that will be connected with interior axle, no longer be engagement by cushion block 43 with the bevel gear set disengagement, axle is free state then, because the thickness of cushion block just equals the miles of relative movement of two finishing bevel gear cuter jump out of mesh states, this distance also is the reach length of interior axle nest groove 44 for screw 41, the nest groove of axle is just on the position of screw 41 in this moment, by tightening screw 41, interior outer shaft can be fixed together, then diaxon has same turning to, if interior axially outer end head install respectively before and after screw propeller, the test form of Here it is tandem propeller.
Under the test condition of counter rotating propeller or tandem propeller, if add conduit 37, then be respectively that tandem propeller adds conduit, counter rotating propeller adds the test form of conduit.
As shown in Figure 5, from separating tectonic position 25, main body measure portion 40 can be pulled down, be installed in the ship model, drive motor links to each other with axle system from left end, then can carry out the ship model self-propelled test test under the above-mentioned various propulsion mode.
As previously mentioned, employing of the present utility model, not only overcome in the naval tank, because the test gear function is single-minded, cause outfit instrument kind numerous and diverse, maintenance management inconvenience, the disadvantage that degree of utilization is low, carry out before and after the tandem propeller hydrodynamic force oar and measure respectively but also opened up, and the tandem propeller counter rotating propeller adds the hydrodynamic force test function of conduit.Because it both can be used for carrying out the open water experiment measurement of screw propeller, can be used for carrying out ship model self-propelled test again and measure again, overcome in the ship model self-propelled test analysis, because of resistance dynamometer setting accuracy difference, the trouble that causes test error to bring.
The utility model is finished by contriver's design and processing and debugging, and every performance all reaches original index.
