Background

The push-pull executing mechanism of the solar (flat single shaft) tracking bracket comprises a driving push-pull executing mechanism and a driven push-pull executing mechanism, wherein the power input shaft of the driving push-pull executing mechanism realizes the telescopic action of the push-pull executing mechanism through the driving of the gear reversing mechanism, and the driven push-pull executing mechanism realizes the synchronous action through the connection with the driving push-pull executing mechanism. The existing gear reversing mechanism is unreasonable in design and usually has only one power output shaft, so the active push-pull actuating mechanism of the existing gear reversing mechanism can only be arranged at the end part of the flat single-shaft tracking bracket, but not in the middle of the flat single-shaft tracking bracket in order to connect the power output shaft with the power input shaft of the active push-pull actuating mechanism. The driving push-pull executing mechanism is arranged at the end part of the flat single-shaft tracking bracket, so that the torque transmitted by the power output shaft is long, the transmission effect is poor, the strength requirement on the driving parts is higher, and the production cost of the parts is increased.

Disclosure of Invention

The utility model provides a gear reversing mechanism of a solar tracking bracket.

The utility model aims to solve the problems that the torque transmitted by a power output shaft is long, the transmission effect is poor, the strength requirement on a transmission part is higher and the production cost is increased due to the fact that the traditional active push-pull actuating mechanism is arranged at the end part of a flat single-shaft tracking bracket.

The driving gear is meshed with the driven gear, and two ends of the power output shaft penetrate through the gear box.

Preferably, the gear box comprises an upper box body and a lower box body, and the upper box body covers the lower box body.

Preferably, two ends of the driving gear are respectively connected with a pair of first support bearings, and the pair of first support bearings are respectively arranged on the inner side of the upper box body and the inner side of the lower box body of the gear box.

The middle part of the power output shaft is tightly sleeved with a pair of second support bearings which are respectively arranged on the inner side of the upper box body and the inner side of the lower box body of the gear box.

The power output shaft outside the second support bearing is sleeved with a framework sealing ring, a rubber sealing ring and an end cover, the framework sealing ring is tightly matched with the end cover and is in clearance fit with a power output moving shaft, and the rubber sealing ring is tightly matched with the power output moving shaft and is in clearance fit with the end cover.

The beneficial effects of the utility model are as follows: the gear reversing mechanism is arranged in the middle of the flat single-shaft tracking bracket, and the double-power output shaft is respectively connected with the square transmission pipes at two sides through the square pipe lining, so that torque can be simultaneously transmitted to two sides.
