heavy gear

In the dynamic analysis of gear, the modeling process is very important. With the development of science and technology, there […]

Under the action of long-term repeated load, gear is easy to produce fatigue microcracks, which leads to the decrease of

In order to solve the problems of dynamic characteristics and crack propagation path of low-speed and heavy-duty gears, the main

The crack propagation of gear can be divided into three stages: the first stage, crack initiation stage; The second stage

Low speed and heavy load gear transmission system is widely used in every lifeline of national economy, such as gantry

The bending fatigue test was designed and completed according to GB / T 14230-1993. In the bending fatigue test, according

Shi uses the software perdynamic (PD), which is used to analyze the crack propagation in the fracture of engineering materials.

Huang believes that the dispersion of fatigue crack growth behavior should be accurately characterized in the structural integrity assessment based

Heavy duty gear is the core component of large equipment transmission, which is widely used in many industries such as

The traditional gas carburizing method uses a single liquid (such as kerosene) carburizing to control the surface carbon content and

In heavy mining and building materials machinery, a large number of large gear pairs with open drive are used. The

Mining machinery, transportation machinery and other low-speed heavy-duty gear, require the use of high reliability carburized hardened gear after grinding.
