Description

Technical Field

[0001] The present application belongs to the field of bearing retainers, and in particular relates to a flexible bearing retainer. Background Art

[0002] As one of the representatives of clean energy, photovoltaic power generation provides endless enjoyment for human green life. Every day as the sun rises, the current converted from solar energy can directly drive washing machines, refrigerators, radios, computers, etc. to work; hot water boiled by solar energy continuously supplies bathrooms and kitchens; if it is rainy, people can use the solar energy stored in the accumulator.

[0003] The current development trend of solar power generation is to use automatic tracking photovoltaic power generation equipment. The various solar panels of this equipment can keep pace with the movement of the sun. Compared with traditional fixed solar photovoltaic power generation equipment that can only generate maximum power for two hours a day, automatic tracking solar panel modules can significantly provide more energy from sunlight radiation.

[0004] In solar power generation equipment, since the adjustment motor movement of the solar power generation equipment has always been in accordance with the same mechanical principle, the motor adjusts the solar panel module to accurately reach each tracking position. The rolling ball bearing ensures the minimum resistance in the tracking movement. In addition, each solar panel module of a set of solar power generation equipment must follow the movement, and many rolling bearings need to be installed and used. The use of rolling bearings is almost irreplaceable.

[0005] According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element and cage. Cage (i.e. bearing cage, also known as bearing retainer) refers to the bearing part that partially wraps all or part of the rolling elements and moves with them, used to isolate the rolling elements, and usually guides the rolling elements and keeps them in the bearing. Therefore, the cage is a very important component of the bearing, and the structure of the cage directly affects the rotation of the rolling elements, affecting the use effect and service life of the bearing.

[0006] And because solar panels are set up in outdoor environments, the pain points of photovoltaic systems in the industry are currently concentrated on the instability of photovoltaic systems under strong wind conditions. On the one hand, due to the large area of ​​photovoltaic modules under strong wind conditions, photovoltaic modules need to withstand large wind loads. When the wind load is transmitted to the photovoltaic bracket, it exerts a large force on the photovoltaic bracket, which poses a great test to the structural stability. On the other hand, outdoor wind and sand accidentally fall into the retaining frame, and due to the special low speed of photovoltaic bearings, jamming and other phenomena may occur, affecting the normal use of bearings and photovoltaic panels.
