Select the seedling taking track in the seedling taking mechanism of double arm second-order free non-circular gear planetary system pot seedling transplanter for comparison, as shown in the figure. In order to facilitate comparison, the following figure establishes a rectangular coordinate system based on the axis of the seedling...
Spiral bevel gear is widely used in power transmission of aviation, vehicles and machine tools because of its stable transmission and strong bearing capacity. In the design and machining stage of spiral bevel gear tooth surface, the expected topological geometry of spiral bevel gear tooth surface is often obtained...
The so-called “cloud points” data refers to the three-dimensional data of the real object measured by various methods in the process of reverse design. When displayed on the computer screen, the image composed of dense three-dimensional data points is like a cluster of clouds, so it is vividly called...
In coal machinery equipment, many gear devices in China are imported from abroad. With the influence of factors such as long procurement cycle, difficult procurement and high cost of imported spare parts, the localization of gear device has become an urgent problem to be solved. As a precision transmission...
3D model reconstruction mainly uses the point cloud data on the model surface collected by spiral bevel gear reverse engineering to construct a model similar to the real object through interpolation or fitting. There are two methods as follows: one is the surface reconstruction method, which synthesizes the spiral...
The processing of tooth surface point cloud in reverse engineering of spiral bevel gear is a very important process, which directly affects the quality of reconstructed 3D model. Due to the defects of scanning equipment, measurement methods, the quality of the surface of the scanned part and the environment,...
Spiral bevel gear is an important part of high-precision equipment. Spiral gear is generally processed by spiral milling machine. Because the production of spiral bevel gears with different specifications requires different molds, the manufacturing cost of single piece and small batch production is very high, and the production cycle...
