Additional torque in the processing of spur gear split wheel blank
It can be seen from the cross-section of the straight shaft that the cutting speed of the straight shaft tends to be faster than that of the neutral shaft, and the straight gear decreases first; When the thickness of material removal reaches 20mm, the decline speed of neutral shaft...

Analysis of additional torque in the process of bevel gear split blank machining
Before bevel gear cutting, the residual stress in the material is evenly distributed and balanced along the thickness direction of bevel gear blank. During the processing of bevel gear blank, the material of bevel gear blank is gradually removed, the original equilibrium stress state is broken, and the residual...

Wear resistant coating on gear surface
Surface coating and surface coating wear-resistant materials increase the wear resistance. For example, Eagle innovations has developed a new metal surface coating “e” – carbon coating, which can be coated on all base metal alloys, has good corrosion resistance, can form a whole with the base without breaking or...

Gear tribology theory
The theoretical research of gear tribology focuses on gear elastic hydrodynamic lubrication (EHL), gear surface morphology, micro tribology and so on. (1) Tsinghua University, Shanghai Jiaotong University, Wuhan Institute of technology and Harbin Institute of technology have completed the research on EHL numerical solution and oil film thickness measurement....

Cutting changes in helical gear turning process
In the process of helical gear turning, each tooth of the turning tool will go through a process from cutting into the workpiece to cutting out the workpiece. In this process, the cutting speed of the gear turning tool at the contact point is constantly changing. The cutting angle...

Processing technology of tractor gear based on ant colony algorithm
In tractor gear processing, the commonly used tools include tractor gear type tools and rack type tools. In the process of tractor gear cutting tool processing, the slotting tool for processing tractor gear is like an external gear with a blade. Its blank makes meshing movement with the tractor...

Processing technology of agricultural machinery gear
In recent years, with the continuous development of computer technology, computer simulation has been applied to the design, processing and manufacturing process of agricultural machinery gears. Through simulation, the three-dimensional modeling, virtual assembly, processing simulation and process optimization of agricultural machinery gears are realized. In the processing of agricultural...

Gear is an important part of the transmission of cars, heavy trucks, motorcycles and other vehicles
Gear is an important part of the transmission of cars, heavy trucks, motorcycles and other vehicles. There are about 18 ~ 30 tooth shaped parts in each automobile gearbox. The quality of the gear has a significant impact on the noise, stability and service life of the automobile. Therefore,...

Helical gear processing technology
Helical gears is the abbreviation of “helical cylindrical gear”, that is, the cylindrical gear whose tooth line is cylindrical helix, which is used to transfer the motion between non intersecting and non parallel shafts. From the perspective of a single gear, it is the same as the helical gear...
