Abstract
According to the power transfer principle of testing stand and the difference of loading method, gear box test table is divided into open power streaming and type closed power flow two major classes.Open power formula gear box test table is loaded by energy-consuming device to gear-box, the power consumption of supply testing stand includes testing the friction loss of the power and each movement chain link of gear-box, power consumption is too many, therefore, occurs as soon as the loading method using type closed power flow.The test of epicyclic gearbox type closed power flow is will to accompany examination gear-box and test that epicyclic gearbox output end, input terminal is corresponding connects, form closed state, and the upper loading device of examination gear-box input side series connection is being accompanied, test gear-box can be loaded；The advantages of this type closed power flow is tested is that power flow recycles in the closed system tested epicyclic gearbox and accompany the compositions such as examination gear-box, and driving device power need to only be equivalent to the frictional dissipation in gear-box closed system.Loading device as type closed power flow test important component can realize the load function of epicyclic gearbox testing stand, reduce the construction scale and fund of testing stand, solve the problems, such as that type closed power flow test load and connection are difficult.This kind of loading device also has reference to the power streaming test load of parallel-shaft gearbox.
Description
Technical field
The present invention relates to the ipsilateral formulas of Gear Planet Transmission mechanical output blocking test platform to load coupling method, such load connection side
Method be the full revolving speed full load testing stand of epicyclic gearbox ipsilateral connection loading system and test epicyclic gearbox, accompany tentative star
Gear-box realizes that defined test load is transmitted in test epicyclic gearbox, the enclosed construction for accompanying examination epicyclic gearbox to be formed,
It is the key that one of full revolving speed full load Test-bed Design coupling method of epicyclic gearbox.
Background technique
The full revolving speed full load test check test epicyclic gearbox design of epicyclic gearbox, manufacture and assembling quality, note
Its vibration noise at runtime is recorded, the engagement and overall performance feelings of the full revolving speed lower gear of the full load of planetary driving device are examined
Condition.
The test of epicyclic gearbox full load is divided into 2 kinds of methods, one is open type test, the testing stand scale of such method,
Wasted work is quite big, the load test suitable for the full revolving speed no load test of small-power or small-power epicyclic gearbox.
Another kind is epicyclic gearbox back-to-back testing, and this method is type closed power flow test method (as shown in Figure 1),
It is to use that examination epicyclic gearbox (2) and the output end of test epicyclic gearbox (3) is accompanied to be connected with output end, input terminal with input terminal
Back-to-back mode form closed state, and on side install additional loading device (1), can carry out gear-box full load performance examination
It tests, this test method is generally called back-to-back testing；Its advantage is that power flow is by test epicyclic gearbox and accompanying examination planetary gear
Circulation in the closed system of case composition, and driving motor (4) power need to only be equivalent to the frictional dissipation in gear-box closed system.
The construction scale of epicyclic gearbox back-to-back testing platform is small, while saving substantial contribution.
The heavily loaded ipsilateral load coupling method of Gear Planet Transmission Tester with Mechanical closed Power formula is gone for realizing loading system and test
Star gear-box accompanies the connection tried between epicyclic gearbox, can effectively solve the full revolving speed full load testing stand of heavily loaded epicyclic gearbox
Load is applied to difficult by coupling in test epicyclic gearbox and the closed system for accompanying examination epicyclic gearbox to form by loading system
The problem of.
Summary of the invention
The ipsilateral load coupling method of heavy duty Gear Planet Transmission Tester with Mechanical closed Power formula provided by the invention, for coupling load
System, accompanies examination epicyclic gearbox to enable to apply defined load at test epicyclic gearbox.Specifically.By loading system ontology,
Export the compositions such as external tooth, output coupling tunnel, output internal tooth, transition external tooth, transition spline, adapter flange, connection spline.
When carrying out the test of full revolving speed full load to epicyclic gearbox, firstly, electric motor starting driving test epicyclic gearbox,
Revolving speed test epicyclic gearbox, chamber and accompany examination case between intermediate coupling structure (connection flange and internal tooth casing), accompany examination
Epicyclic gearbox, loading system (ontology, output external tooth, output coupling tunnel, output internal tooth, transition external tooth, transition spline, switching
Flange, connection spline), intermediate coupling spindle, the formation such as test epicyclic gearbox sun gear closed system inner sealing, motor at this time
Output power be only friction power loss in closed system, then can improve motor input speed according to test determination until reaching
Revolving speed needed for testing epicyclic gearbox.Then loading system starts to apply torque, realizes that torque recycles in closed system, adjusts
Loading system is until torque needed for reaching test epicyclic gearbox；The full revolving speed full load test of epicyclic gearbox is completed at this time.
The technical problems to be solved by the invention:
In order to realize the load of the full revolving speed full load test of epicyclic gearbox, coupled using the ipsilateral load of Tester with Mechanical closed Power formula
Method solves the problems, such as that difficulty is realized in ipsilateral coaxial line load and coupling structure, realizes in test epicyclic gearbox, accompanies tentative star
Power flow circulation in the closed system of gear-box and loading system composition, drives their motor power (output) that need to only be equivalent to row
Frictional dissipation in star gear-box closed system, to complete the full revolving speed full load test of epicyclic gearbox.
Detailed description of the invention
Attached drawing is the schematic diagram and structural schematic diagram of this patent.
Specific embodiment
The following further describes the present invention with reference to the drawings.
Fig. 1 is the structure of the ipsilateral load coupling method of the full revolving speed full load test machines type closed power flow of epicyclic gearbox
Schematic diagram.Specific connection is by loading system ontology (1), output external tooth (6), output coupling tunnel (7), output internal tooth (8), transition
The components composition such as external tooth (9), transition spline (10), adapter flange (11), connection spline (12).
When carrying out the test of full revolving speed full load to test epicyclic gearbox (3), firstly, motor (4) starting driving test
Epicyclic gearbox (3), revolving speed test epicyclic gearbox (3), test epicyclic gearbox (3) and accompany examination epicyclic gearbox (2) it
Between intermediate coupling structure (5) (including connection flange (15) and internal tooth casing (16)), accompany examination epicyclic gearbox (2), loading system
(including ontology (1), output external tooth (6), output coupling tunnel (7), output internal tooth (8), transition external tooth (9), transition spline (10),
Adapter flange (11), connection spline (12)), intermediate coupling spindle (13), the formation such as test epicyclic gearbox sun gear (17) envelope
System inner sealing is closed, the output power of motor (4) is only the friction power loss in closed system at this time, then can be according to test determination
Motor (4) input speed is improved until revolving speed needed for reaching test epicyclic gearbox (3).Then loading system (1) starts to apply
