Friction resistance widely exists in actual production and our life. The friction between moving pairs will lead to the gradual loss or migration of part surface materials, that is, the formation of wear. Wear not only consumes energy and materials, reduces the operation efficiency of equipment, but also accelerates...
Mainly from the perspective of reverse engineering, this paper studies the three-dimensional geometry of the gear surface and establishes its three-dimensional solid model, so as to prepare for the analysis of its friction and wear performance in the process of gear meshing transmission in the future. Specific work has...
Double circular arc gear is a new improved form of traditional gear, which is widely used in the reducer of pumping unit and hoist. There are about 55000 pumping units in operation in Daqing Oilfield, and about 2% of the pumping units fail to shut down every year. More...
The research conclusion of reverse engineering of logarithmic spiral bevel gear is mainly reflected in the following aspects: 1.The tooth surface data points of logarithmic spiral bevel gear are collected by 3D laser scanner, and the collected tooth surface data information is processed by inverse software Imageware. There are...
Based on the research of reverse technology of logarithmic spiral bevel gear, this paper expounds several important links in the research of reverse design. Because the logarithmic spiral bevel gear is a new type of gear, which is widely used in various fields of industrial production, special analysis and...
The surface reconstruction of logarithmic spiral bevel gear is to construct a real logarithmic spiral bevel gear tooth surface by interpolation using the discrete data points of the tooth surface collected. The tooth surface reconstruction of logarithmic spiral bevel gear is the core part of the whole digital model....
According to the function of the mechanism in the seedling picking cycle, the whole movement is divided into four processes: seedling picking, seedling transplanting, seedling releasing and recovery, and the corresponding mechanism trajectory is also divided into four segments. The trajectory curve is fitted with cubic non-uniform B-spline curve....
Reverse engineering is a reverse process of product design. The general product design is to design the shape and some basic parameters of the product according to the service performance of the product, use the three-dimensional modeling software to build the digital model of the product, and then input...
The schematic diagram of the seedling taking mechanism of non-circular gear planetary gear train is shown in the figure. The mechanism is symmetrically arranged with two arms. The transmission process is analyzed by the upper right half of the mechanism: the planet carrier 1 is hinged with the sun...
Using the physical reverse engineering method to collect the discrete data points of the tooth surface of the logarithmic spiral bevel gear can not only reconstruct the tooth surface of the logarithmic spiral bevel gear, but also calculate the error between the real tooth surface and the theoretical tooth...
