Firstly, the overall layout of the whole planetary gear transmission structure is carried out in CAD, and the plane layout of the whole structure is shown in Figure 1: The parametric simulation model is established in solidworks, and the simulation part drawing obtained from parametric 3D modeling is shown...
To ensure the effectiveness of the improvement, modeling and simulation analysis were conducted on the improved state planetary reduction mechanism. In response to the local tooth breakage of the planetary gear and floating gear ring during the fault, the planetary reduction mechanism in this section was intercepted for analysis...
According to theoretical calculations, the strength design of each gear in the planetary reduction mechanism meets the requirements. According to the fault phenomenon of the faulty component, both the planetary gear and the floating gear ring are locally broken teeth, so it is considered that the cause of the...
The planetary gear reducer has made improvements to the rotating actuator in response to the cause of the malfunction. To improve the torsional stiffness of the planetary carrier, the outer diameter of the planetary carrier is increased while the structure and principle remain unchanged to enhance the stiffness. The...
Planetary gear reduction mechanisms have the advantages of small size, large load-bearing capacity, high transmission efficiency, and high transmission ratio, and are widely used in the aviation field. They are an important component of aviation gear rotary actuators and are commonly used in applications such as opening and closing...
In addition to helical gears and spur gears, there are several other types of gears that can be used in various applications, each with its own advantages and disadvantages. Some common types include: Selecting the appropriate gear type depends on the specific requirements of the application, such as space...
Transmission error is a key performance indicator for evaluating the transmission accuracy of planetary gear transmission systems, and it is also a source of excitation for vibration and noise in planetary gear systems. At present, research on transmission error is mostly limited to the analysis and testing of a...
In the Xinjiang region, there is an extremely harsh environment, with extreme heat and cold conditions. The location of the wind turbine often experiences extreme weather such as wind and sand, coupled with the uncertainty and non-uniformity of the wind flow size, resulting in the randomness of the input...
Wind power generation, as a clean and pollution-free energy source, has been widely used globally in recent years. Its structural diagram is shown in Figure 1. Wind power drives the blades of a wind turbine to rotate. Due to the large size and mass of the blades, the speed...
1.Strength analysis of planet carrier In the planetary reducer, the planet carrier is often the part with the largest torque, and its modeling structure features are many, which is not conducive to theoretical calculation, so we carry out finite element analysis on the planet carrier. According to the above...
