1. Actual meshing line length before trimming The meshing transmission range of a pair of gears is limited, as shown in Figure 1. AE is the actual meshing line of the gear teeth, and the ratio of its length to the normal pitch of the gear tooth base circle...
When selecting the right gear solution for a particular application, it is important to consider the specific requirements, operating conditions, and performance characteristics. While worm gears offer unique advantages, it’s essential to compare them to other gear types to make an informed decision. Here’s a comparison between worm gears...
According to the meshing characteristics of spur gear, the gear teeth just entering the mesh do not bear the load, and all the load is borne by the previous pair of teeth. At this time, considering the small deformation, meshing thermal deformation and cutting error after being loaded, the...
When it comes to heat treatment for spur gears, helical gears, and bevel gears, there are several key considerations to keep in mind. Heat treatment is a crucial process that enhances the mechanical properties of gears, improving their strength, hardness, and wear resistance. Here are some important factors to...
The transmission device of locomotive bogie is mostly a first-level spur gear reduction structure and the actual operating speed varies widely. Therefore, not only the actual overlap, the load distribution between teeth and the excitation force should be considered when designing the gear tooth trimming amount, but also the...
The advantages and disadvantages of feature extraction can determine the complexity and difficulty of the algorithm. A simple understanding is to extract the region of interest in the image. The target of feature extraction of spur gear image is to obtain the corresponding in-range divergence in the subspace. At...
The calculation of threshold segmentation is simple and efficient, but the selection of threshold needs to be determined according to the specific spur gear defect image; The segmentation effect based on region growth is good, but this method increases the computational complexity and cannot obtain complete defect regions. It...
Image enhancement is to improve the image definition. Unlike the original image, image enhancement does not need to completely reflect the original image, but displays some distortion more clearly. The purpose of image enhancement is to better improve the visual impact of the image. In a special area, the...
In the process of image acquisition, the lighting equipment can not uniformly cover the surface of the spur gear housing, and some spur gears will have defects such as grooves, resulting in uneven illumination of the spur gear, and the spur gear defect image has noise, so first use...
With the rapid development of the manufacturing industry and the continuous improvement of market demand, the demand and quality of spur gears are becoming higher and higher. Spur gears will be affected by various factors in the specific production process, resulting in defects on the surface of spur gears....
