Description

Technical Field

[0001] The utility model relates to a driving device, in particular to a motor rotor rotation driving device with adjustable belt tension. Background Art

[0002] The generator rotor is the rotating part of the generator, which is mainly composed of conductive rotor windings, magnetic iron cores, rotor shaft extensions, guard rings, center rings and fans. After the generator rotor is produced and processed, a dynamic balancing test device is required to perform a dynamic balancing test on the rotor to ensure the stable use of the rotor.

[0003] The patent publication number is CN205808623U, and the patent name is a patent for a dynamic balancing test device. It discloses a dynamic balancing test device, including a test bench, a left support mechanism and a right support mechanism. An intermediate power disk is also arranged between the left support mechanism and the right support mechanism. The left support mechanism has the same structure as the right support mechanism; the left support mechanism includes a left base, a left lower frame body installed on the left base, and a left upper support rod, a left lower support wheel is installed on the left lower frame body, and a left upper support wheel is installed on the left upper support rod; a motor and a pulley mechanism are installed on the intermediate power disk; a left piezoelectric sensor device is installed on the left support mechanism, and a right piezoelectric sensor device is installed on the right support mechanism, wherein the fixing points of the left support mechanism, the right support mechanism and the intermediate power disk can be adjusted along the groove to adapt to the dynamic balancing test of shaft rotors of different lengths, and the support wheel can also be adjusted up and down to adapt to the dynamic balancing test of shaft rotors of different shaft diameters, and has strong versatility.

[0004] In the existing test of motor rotor dynamic balancing, the rotation of the rotor is completely dependent on the friction between the belt and the outside of the rotor. Therefore, the staff needs to replace the belt that is compatible with the rotor according to the type and specification of the rotor to prevent large test errors caused by too little or too much rotor friction. However, in actual tests, the belt will inevitably produce a certain amount of stretching after long-term use, and the stretched belt will further increase the test error in the test of other rotors.
