Described in this utility model embodiment, the Flange joint above handle shoulder 2 has arm 10；Described arm 10 is connected with column 12 by supporting plate 11.
In this utility model embodiment, described column 12 having a motor and rotary reducer, described motor drives rotary reducer, and rotary reducer is connected with motor, thus reaches to drive the purpose of girder.
The beneficial effects of the utility model are:
(1) use photovoltaic ball bearing can make the product formation a standard universal type product of flat uniaxial tracking bracket as the rotation connection structure of flat uniaxial tracking bracket girder, significantly reduce design efforts would.This universal product can be installed on the mountain region of different gradient, and rotation connection structure has Self-aligning and Self-balancing, and the angle installing tracking support girder will be the most parallel with surface slope, and it is the most convenient to install.
(2) it is sphere-contact due to the way of contact in the range of random working angle of the photovoltaic ball bearing, therefore photovoltaic ball bearing can bear the axle power on random working angle direction, and this axle power is by transmitting between both contact spheres, by attachment structure, photovoltaic ball bearing is attached with girder, such that it is able to the component of flat uniaxial tracking bracket system gravity is transferred uniformly into each root post, whole system stress is the most reasonable.
(3) little due to this photovoltaic ball bearing rotation friction, the arm of force of friction moment is the shortest, frictional force the additional moment produced can be ignored.And follow the tracks of the position of center line that center of rotation is photovoltaic ball bearing of support girder, can reach to follow the tracks of the center of gravity line of mounting system by the installation site of regulation photovoltaic ball bearing and overlap with photovoltaic ball bearing centrage, reach " zero bias " state；So driving force required during system work is the least, motor and the specification of rotary reducer that tracking support needs are relatively small, and cost has obtained significantly reducing.
