Description
Technical field
The utility model relates to a kind of testing apparatus of generator, specifically a kind of device for testing power of small outer rotor generator.
Background technology
Existing small generator all is an internal rotor, and Shang Weijian has outer rotor generator to have commodity commercially available, does not see the device for testing power of outer rotor generator.
Summary of the invention
The purpose of this utility model is the power test problem that solves small outer rotor generator, develops the device for testing power that can test outer rotor generator
The technical scheme that provides according to the utility model, end at test board is provided with support, the other end is provided with variable-frequency motor, scroll chuck is set on support, between scroll chuck and variable-frequency motor, variator is set, the input shaft of described variator utilizes shaft coupling to be connected with the output shaft of variable-frequency motor, on the output shaft of variator dynamometer is installed, and connects circular tie-plate in the end of the output shaft of variator; The centre of gyration of described scroll chuck is concentric with the output shaft of variator.
Described variator is installed on the described test board.Described dynamometer is installed on the described test board.The outer rim of described circular tie-plate utilizes bolt to connect tested external rotor electric machine outer rim; The rotating shaft of described tested external rotor electric machine is connected with described scroll chuck.The output shaft of described variator and input shaft are all concentric with the output shaft of variable-frequency motor.
The utility model has the advantages that: existing generator is internal rotor, and the shell support of fixing tested generator during test on test board gets final product.The outer rotor generator test time is that its shell rotates, and makes the conventional apparatus can't fixed generator, must fix generator with this autocratic device.Because design the time considers that the specification, rotating speed of generator etc. are all multifactor, thus added an adjustable bidirectional speed changer of machinery, and, can survey any low speed, middling speed and high-speed engine by the variable-frequency motor startup.Moment of torsion dynamometer in the middle of being installed at can reflect input torque and multiple parameters such as power input and rotating speed, easy, the safety, reliable of dismounting when testing, and the use place is little, noise is low, the observed and recorded parameter is easy.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
The utility model comprises test board 1, variable-frequency motor 2, shaft coupling 3, variator 4, dynamometer 5, circular tie-plate 6, bolt 7, scroll chuck 9, support 10 and screw 11.Among the figure 8 is tested outer rotor generator.
As shown in the figure: the end at test board 1 is provided with support 10, the other end is provided with variable-frequency motor 2, scroll chuck 9 is set on support 10, between scroll chuck 9 and variable-frequency motor 2, variator 4 is set, the input shaft of described variator 4 utilizes shaft coupling 3 to be connected with the output shaft of variable-frequency motor 2, dynamometer 5 is installed on the output shaft of variator 4, is connected circular tie-plate 6 in the end of the output shaft of variator 4; The centre of gyration of described scroll chuck 9 is concentric with the output shaft of variator 4.
