Description

Technical Field

[0001] The invention relates to the technical field of rotary reducers, and in particular to a rotary reducer for a photovoltaic tracking bracket. Background Art

[0002] A slewing reducer is a mechanical device that converts the output of a high-speed rotating motor into a low-speed, high-torque rotating power. It is mainly composed of a swing arm, an eccentric shaft, a gear pair, a bearing and other components. It uses a planetary gear transmission system and can achieve the conversion of high-speed rotation and low-speed, high-torque. It has high precision and stability. The slewing reducer can accurately adjust the receiving angle of the solar panel in the photovoltaic power generation system to ensure that the panel is always at the optimal receiving angle, thereby improving the power generation efficiency. ‌‌ The utility model disclosed in the publication number CN219554754U discloses a two-way output rotary reducer and a photovoltaic tracking system, which transmits power between the motor and the worm by setting a transmission shaft, and uses cylindrical gear meshing transmission between the transmission shaft and the worm. The two cylindrical gears are arranged in parallel, which requires less space for placement, thereby reducing the overall volume of the box. And under this transmission mode, the motor is close to the middle of the box. Therefore, the rotary reducer of the present application is used to drive the photovoltaic panel, and the photovoltaic panel is not easily interfered with by the box or the motor, and the rotation range is large.

[0003] The invention with publication number CN113794324A discloses a sub-rotation reducer for a photovoltaic bracket, which divides the output shaft into an output outer shaft and an output inner shaft, and controls the torque transmission between the output outer shaft and the output inner shaft through a torque limiting mechanism. When the input shaft of the sub-rotation reducer stops operating, when the torque of the photovoltaic panel main shaft on the active side driving the input inner shaft to rotate is greater than a preset value, the output outer shaft and the output inner shaft can be directly separated, so that the input inner shaft rotates independently, thereby preventing the reduction mechanism in the reducer from being damaged.

[0004] However, the above-mentioned rotary reducer for photovoltaic tracking brackets still has the following problems during actual use: although transmission deceleration is achieved through a worm mechanism and a bevel gear mechanism, the deceleration effect achieved by such mechanisms during operation is poor, and it is difficult to effectively adapt to the speed and rotation of light, which in turn causes the photovoltaic tracking bracket to be misaligned. At the same time, the transmission efficiency of such deceleration mechanisms is low, and the transmission accuracy is insufficient, thereby being unable to guarantee the stability of the tracking bracket.

[0005] Therefore, we propose a slewing reducer for a photovoltaic tracking bracket in order to solve the above-mentioned problems. Summary of the invention
