Compared with prior art; Test run coupling arrangement of the present invention is used to connect two gear case slow-speed shafts; Form four spline pairs and connect, because all there is backlash in each spline pair, to radially having certain compensation ability between two gear case slow-speed shafts with the angle error of centralization; End play between coupling shaft and the transmission shaft makes axially easy to adjust, has the compensation ability of very big axial alignment error; Can effectively reduce act on gear case slow-speed shaft shaft extension add radial force and axial force, have certain damping effect, reduce and accompany of the influence of examination gear case operational situation main examination gear case; This device has designed screw rod, removes during test run, plays the clutch guide effect during dismounting, reduces the operation element amount and the time of clutch; Adopt spline pair to connect easy accessibility, need be as flange connect centering axial location again, attachment bolt then, thus reduce test run setup time; Also need not consider bolt strength, pretightning force size, avoid repeatedly dismounting wearing and tearing and lost efficacy that connect safe and reliablely, this device transmission process power attenuation is little, transmission efficiency reaches more than 99.5%, and driving torque is big, can satisfy the various operating modes of testing table.
Description of drawings
Fig. 1 is a wind-powered electricity generation type approval test stand layout.
Fig. 2 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is remake and to specify.
Referring to Fig. 1～Fig. 2; The type approval test of aerogenerator is the moment of torsion output test to motor A and generator F; Try gear case C (reductor) and main examination gear case E (gearbox) in motor terminal and the supporting respectively setting of generator end by accompanying of shaft coupling B connection, and connect the slow-speed shaft of two gear casees, thereby test the input requirement whether input speed satisfies generator through test run coupling arrangement D; Make generator work, thereby realize generating.
This test run coupling arrangement D includes coaxial mounted first coupling shaft 3, transmission shaft 7 and second coupling shaft 9; One end of first coupling shaft 3 with accompany examination gearbox output shaft 1 (slow-speed shaft) grafting interference fit joint, both form the interference structures through locking plate 2, said locking plate 2 is made up of the part that two cone match link; This locking plate is an outsourcing piece; Brand is Stuwe, and model is HYD22, is applicable to the gear case slow-speed shaft part that wall thickness is thin.The other end of first coupling shaft 3 and transmission shaft 7 one ends are the male splines structure, and first spline housing 4 is the female spline structure, are sleeved on above-mentioned first coupling shaft and the transmission shaft, constitute two spline pair engagements, and this spline is involute spline (as follows).
Said transmission shaft 7 supports with supporting seat 12, and supporting seat is fixed on the stand, supporting seat coupling spindle bearing 6, and cardan-shaft suspension a pair of symmetrically arranged in bearing seat done by inner and outer sleeves can bear bi-directional axial power in the taper roll bearing 11 of axial location.
One end of the other end of transmission shaft 7 and second coupling shaft 9 is similarly the male splines structure, constitutes two spline pair engagements with second spline housing 8.The burst at the seams backlash of spline of Zhejiang makes and radially has certain compensation ability with the angle error of centralization between two gear case slow-speed shafts.
The other end of second coupling shaft 9 is pegged graft with main examination gear case slow-speed shaft 10, equally the locking plate 2 ' formation interference fit joint through outsourcing.
Be provided with end play between described coaxial mounted first coupling shaft 3, transmission shaft 7 and second coupling shaft 9, end play is preferred version with 20mm, is convenient to the compensation of the axial alignment error of convenient adjustment.
Simultaneously on first spline housing 4, bearing seat 6 and second spline housing 8, be equipped with lubrication hole 13, and all be fixed with side plate in both sides separately and make axial limiting.Being provided with the screw rod 5 of circumference uniform distribution between the first spline housing right side side plate and bearing seat left side side plate, bearing seat right side side plate and second spline housing left side side plate, is preferred version with 2.The axial slip of spline housing is convenient in the setting of screw rod 5; Make gear case when dismounting is keeped in repair, play the clutch guide effect; For example first spline housing in Fig. 2 left side can be along screw rod near the slippage of bearing seat direction behind the attachment screw of removing the left side; That throws off that first coupling shaft connects accompanies the examination gear case, and the screw-rod structure on Fig. 2 right side is identical with function, repeats no more.But this screw rod 5 must be removed when test run.
Transmission of power of the present invention is exactly by the motor output speed; Make the output shaft output slow-speed of revolution of accompanying the examination gear case through shaft coupling; Make the slow-speed shaft of main examination gear case obtain the slow-speed of revolution through first coupling shaft, transmission shaft and second coupling shaft again; The generator that is connected by shaft coupling at last drives generator work obtaining to carry out the moment of torsion transmission under the prerequisite that input speed requires.The present invention's first spline housing is identical with the second spline housing structure, one-piece construction symmetry, simple, and constituent part is few.
The present invention not only can be used for the test of wind-powered electricity generation gear case pattern, through changing the syndeton scheme of two ends coupling shaft and gear case, also can be used for other type approval test occasion, is particularly useful for the load test of bulk article.
