Summary of methods for gearbox vibration analysis and diagnosis
There are three specific analytical and diagnostic methods to detect vibration faults in gearboxes. One，Time domain averaging method The principle is to eliminate noise interference in the detection signal The main points of this method applied to fault analysis are: ① there should be two detection signals, one is the vibration signal, and the other is the time scale signal of the rotation of the rotor shaft; ② smooth filtering; ③

Gearbox is a kind of variable speed device that achieves variable speed effect through the meshing of large and small gears, and has many applications in the variable speed of industrial machinery. In the gear box, there is a large gear installed on the low-speed shaft and a small gear installed on the high-speed shaft, and the process of acceleration or deceleration can be completed through the meshing and transmission effect between the gears. The characteristics of the gear box are as follows:
Assembly steel plate warehouse production introduction
Assembly of steel plate silo referred to as assembly silo, it is the mechanical roller and molded into a corrugated plate punching, electric torque wrench through the high-strength bolts connected to the assembly of a kind of steel plate silo. The wall plate of the assembly silo is
Gearbox lubrication is very important, good lubrication can play a sufficient protective effect on gears and bearings. For this reason, we must attach great importance to the lubrication of the gear box, in strict accordance with the specifications to maintain the lubrication system in the best condition for a long time. Gearboxes often use splash lubrication or forced lubrication, generally with forced lubrication is common. Therefore, it is particularly important to have a reliable lubrication system. Electric gear pump from the tank will be oil through the oil filter to the gear box lu
The gearbox system contains gears, drive shafts, bearings and box structure. Among them, the box structure plays a supporting and sealing role in the whole system, and its probability of failure is very low, so in the gearbox, the failure mainly occurs in gears, drive shafts and bearings. According to statistics, gears, shafts and rolling bearings failures account for more than 90% of gearbox failures. In the fault diagnosis of gearboxes, it is generally only necessary to give whether a fault is generated and where the fault occu
China's steel plate warehouse also has a certain field
Steel plate warehouse is first more than a hundred years ago in foreign countries to be widely used, China's steel plate warehouse skills started late. 1982, the introduction of galvanized corrugated sheet assembled steel plate warehouse from the U.S., the steel plate warehouse is the earliest modernization of the steel plate warehouse group presented in the country.Developed to the present, China's steel plate warehouse also has a certain planning.
What are the reasons for choosing fly ash steel plate silo
Fly ash is a fine granular stage, will be used in many places, such as power plants, etc., thought his volume is too small, if encountered in the wind and other weather will cause dust pollution, so it is not suitable for open-air storage, we need to put the fly ash in the steel plate warehouse for storage, the next to share with you the reasons for choosing the steel plate warehouse storage of fly ash!
What to watch out for if storing powdered objects in steel plate silos
Steel plate warehouse used to store powdered objects is not three years two years, the steel plate warehouse with its own strength to occupy a lot of storage, become a favorite of consumers, this is because the steel plate warehouse not only what can be loaded, like common cement, fly ash, slag, grain, building materials, as well as some of the chemical industry will be used in the steel plate warehouse, called him the storage of the world's bearer is not an exaggeration!
Dry 丨 wind turbine gearbox lubricant foam causes
Lubricant foam generated during the use of lubricants will not only occur in the air resistance and flow breakage phenomenon, but also lead to fatigue wear and lubricant consumption, therefore, the lubricant is required to have good anti-foaming properties. Briefly analyze the reasons for the formation of lubricating oil foam and harm, and summarize the common physical and chemical methods to reduce foam and its mechanism, citing the addition of anti-foaming additives and pre-heating of the lubricant to control the foam content of the case. Foam formation caus
