Summary of the invention
In order to solve the apparatus structure complexity of test wind power generation reductor every performance under running status in the prior art, the use cost height, operate loaded down with trivial details, testing reliability is low, shortcomings such as poor practicability, the purpose of this invention is to provide a kind of simulation wind power generation running environment and test, convenient test, accurate, safe rotary testing device of variable pitch speed reducer.
Technical scheme of the present invention is: a kind of rotary testing device of variable pitch speed reducer, comprise casing, left and right support, main shaft, loader, its technical characterstic is that described casing is " ⊥ " shape, be penetrated with the main shaft that horizontal box is stretched out at two ends in the horizontal box of casing, suit one bevel gear on the main shaft, two case lids pass the sealed at both ends horizontal box of main shaft two ends respectively, and being arranged with a circle on the end flanges face of horizontal box, to be uniformly distributed in the horizontal box axle center be bolt hole on the circumference at center; Be provided with a locating sleeve in the vertical casing of casing, connection one places the flange cover of vertical casing endpiece on the locating sleeve, and through another bevel gear of Bearing Installation, two bevel gears are engagement in the locating sleeve;
Be respectively equipped with the supported hole of horizontal direction on the described left and right support, described main shaft two ends make casing be no gap rotation status between left and right support in bearing is supported on supported hole on the left and right support, the periphery in left socle or right support upper support hole is arranged with a circle and the corresponding bolt hole of horizontal box one end flanges face upper bolt hole, and two bolts hole make the casing that rotates to an angle be stationary state through bolt locking.
Further, the bevel gear in the described locating sleeve is provided with the endoporus that cooperates with the variable pitch speed reducer output shaft.
Again further, the crossed axis angle of described two bevel gears is the 40-160 degree.
Testing procedure of the present invention is: the change slurry speed reducer output shaft that will have variable-frequency motor cooperates installation with the endoporus of vertical casing locating sleeve internal bevel gear; After rotating box makes casing be different angles, adopt bolt to pass bolt hole corresponding on support and the casing casing that is locked, the running of energized variable-frequency motor, loader loads moment of torsion simultaneously, the performance requirement loading and frequency conversion rotating speed of motor of reductor is starched in the change of test as required, power and loader moment of torsion, in the test process, can on change slurry reductor, read and become slurry reductor rotating speed, power, on loader, read and become slurry reductor moment of torsion, use the infrared ray test to become operation oil temperature in the slurry reductor, use the vibration transducer test to become the operational shock of slurry reductor, use the noise inspector test to become performances such as slurry reductor running noises, after finishing, test unclamps set bolt, adjust one by one casing on support setting angle and be locked and repeat above-mentioned test, to becoming slurry reductor different azimuth aloft, the combination property of height is carried out complete detection.
Rotary testing device of variable pitch speed reducer compact conformation of the present invention, esy to use, safe and reliable, only need to change the fixing different angles of proving installation casing, can go out to become the combination property that the slurry reduction gear is in aerial different azimuth, height in use by simulation test, test comprehensively, the degree of accuracy height, also can be used for the test of other similar structures product, work efficiency can improve more than 50%.
