Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to Fig. 1 and Fig. 2, a kind of vertical hydrogenerator rotor surveys circle device, by rotor field spider 10, positioned at rotor field spider
Rotation combination mechanism on 10 and the location tray between rotor field spider 10 and rotation combination mechanism 1 form；Wherein rotate
Combined mechanism includes steel ball 2, lower retainer ring 3, regulating device 4, ball bearing 5 and upper retainer ring 6, and steel ball 2 is mounted in down
It is used for supporting the quality of entire rotating part in retainer ring 3 and mitigates in plane rolling resistance；Ball bearing 5 divides for 3 groups of 6 branch
Point by shaft coupling between upper and lower retainer ring 3, in rotation combination mechanism one side equipped with stent 8, is equipped in one end of stent 8
Slide measuring staff 9.
Rotor rim 11 and rotor magnetic pole 12 are installed in 10 one side of rotor field spider, the side of rotor field spider 10 is with sliding
Measuring staff 9 is fixedly linked.
Alternator shaft 7 is placed among the rotation combination mechanism, the alternator shaft 7 is by being located at rotation combination machine
