Description
Technical field
The present invention 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 objective of the invention is to solve the power test problem of small outer rotor generator, develop a kind of device for testing power of small outer rotor generator.
According to technical scheme provided by the invention, 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.
Advantage of the present invention is: 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 invention.
Embodiment
The present invention includes 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.
Described variator 4 all is installed on the described test board 1 with dynamometer 5.When needing test, the outer rim of described circular tie-plate 6 utilizes bolt 7 to connect the outer rim of tested external rotor electric machine 8; The rotating shaft of described tested external rotor electric machine 8 is connected with described scroll chuck 9, so that position for described tested external rotor electric machine 8.
The output shaft of described variator 4 and input shaft are all concentric with the output shaft of variable-frequency motor 2.Whole device is on the same axis, helps the transmission of whole layout and torque.
Principle of work: on test board 1, a scroll chuck 9 is installed on the intermediate vertical face of a support 10, be used to block the main shaft of outer rotor generator 8, the circle at outer rotor generator 8 edges or claw type projection and the dismountable bolt 7 of circular tie-plate 6 usefulness that rotates synchronously link together, circular tie-plate 6 vertically is flush-mounted on the horizontal output shaft of an adjustable bidirectional speed changer 4, the input shaft of variator 4 links together with shaft coupling 3 and variable-frequency motor 2, variable-frequency motor 2 is driven by the frequency converter that is a bit larger tham the motor output power, with frequency converter and 4 combinations of machine two-way variator, can test the outer rotor generator 8 of any rotating speed.After screw 11, support 10, scroll chuck 9, tested external rotor electric machine 8, bolt 7 and circular tie-plate 6 are removed, the internal rotor generator can be installed easily, internally rotor generator is finished the test of parameters.
