Background

In order to realize the rotation of the spindle on the column, a spindle bushing and a bushing seat are usually required to be disposed on the column, so that the spindle passes through the spindle bushing and forms a rotating fit with the bushing seat. Because photovoltaic systems are generally used outdoors, the main shaft and the main shaft bushing need to bear certain load, and under the harsh working environment in the field, the main shaft bushing on the main shaft is easy to age and wear. Therefore, the main shaft bushing is generally made of an engineering plastic material with high structural strength, self-lubricating capability and aging resistance, and is designed into a two-half combination mode so as to be convenient to install.

In the prior art, the half shaft bushing with a double-shoulder structure is assembled to form the main shaft bushing, so that the main shaft bushing can be effectively prevented from sliding out of the bushing seat when in use. However, due to the design of the shoulders, when the two shoulder half shaft bushings are installed in the bushing seats, a space for avoiding the structure of the shoulders needs to be formed, namely, after the two shoulder half shaft bushings are installed, a certain gap is formed between the two shoulder half shaft bushings, and the larger the gap is, the smaller the structural strength of the gap is. The main shaft bushing can rotate at a certain angle along with the rotation of the main shaft in the use process, and when the gap rotates to the bottom, the bearing capacity of the main shaft bushing is reduced, so that the working stability of the main shaft bushing can be influenced. Therefore, there is a need for an improved structure of a double-shoulder half shaft bushing, and a main shaft bushing with higher structural strength is combined.
