The manufacturing accuracy of spiral bevel gear directly affects the transmission efficiency, noise, motion accuracy and service life of machinery and equipment. Therefore, the processing and manufacturing of spiral bevel gear has also been widely concerned and studied by experts at home and abroad. The traditional spiral bevel gear...
Gear processing technology can be roughly divided into four stages: gear blank processing, gear profile processing, heat treatment and finish machining after heat treatment due to different gear structure shape, accuracy grade and production conditions. Gear blank machining must ensure the accuracy of machining datum. Tooth profile machining and...
With the improvement of forging technology, many manufacturers at home and abroad have adopted precision forging technology, changing the short tooth and straight tooth processing technology to precision forging tooth profile, which is realized by extruding tooth profile. By changing the traditional gear hobbing technology, the gear quality is...
The research on the manufacturing technology of spiral bevel gear in China started relatively late. In 1971, Chinese researchers began to study the meshing mechanism of spiral bevel gear transmission from the mathematical formula theory, and took “Gleason gear system” as the initial goal. In the 1990s, the six...
In the 18th century, the French geometer T. Olivier first proposed the concept of spiral bevel gear, but due to the processing technical conditions at that time, spiral bevel gear could not be processed. This situation was not until the 20th century, the emergence of spiral bevel gear processing...
Internationally, power transmission gear devices are developing in the direction of miniaturization, high speed and standardization. The application of special gears, the development of planetary gear devices and the development of low vibration and low noise gear devices are some characteristics of gear design. In order to achieve the...
Gear is the key part of gearbox system, so it is very important to establish the coupling force element between rigid body model and gear pair. In the gear module of the multi-body dynamics software used, there are more precise gear parameter modeling attributes. The main gear modeling interface...
According to the rigid body multi-body dynamic motion analysis theory and modeling ideas, the single-stage gearbox can be dissected and analyzed according to the motion relationship of each component. The kinematics topology after analysis is shown in figure (a). Among them, taking the earth as the system’s fixed reference...
There are some problems in gear meshing excitation modeling ① The time-varying meshing stiffness and static transmission error are scalars varying with time (or rotation angle), so it is impossible to calculate the eccentric load on the tooth surface caused by the inclination of the gear axis and the...
The loosening of the valve clamping part adopts the gear ring transmission mode. The gear ring transmission ratio is constant, the transmission power is large, the efficiency is high, and the service life is long. It is a stable and reliable transmission mode, and the small opening angle of...
