Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic support technical field especially a bearing assembly and photovoltaic support. BACKGROUND

[0002] The photovoltaic support is an important component for supporting, fixing and adjusting the photovoltaic assembly in the solar photovoltaic power generation system. When the main shaft of the photovoltaic support rotates, the inclination and azimuth of the photovoltaic assembly can be adjusted in real time, so that the photovoltaic assembly always faces the sun, thereby improving the solar radiation received by the photovoltaic assembly and improving the power generation efficiency. In the multi-point driving photovoltaic system, synchronous shafts are usually used for multi-point driving. When working, the driving motor drives the main shaft and the synchronous shaft to rotate synchronously, and the power of the driving motor is transmitted to the multiple driven driving points through the synchronous shaft, forming multi-point driving.

[0003] The main shaft and the synchronous shaft are supported by the bearing seat during operation. The bearing seat bears the radial and axial loads generated by the main shaft or the synchronous shaft during operation, so as to ensure that the main shaft or the synchronous shaft can rotate smoothly. In the prior art, the bearing seat is generally composed of two semicircles. During installation, multiple pairs of bolts are needed for connection and fixation, which not only increases the complexity of installation, but also increases the installation time of the on-site workers.
