Types of coordination (1) Clearance fit The cooperation with clearance (including minimum clearance equal to zero) is called team cooperation. At this time, the tolerance zone of the hole is one of the tolerance zones of the shaft As the actual dimensions of the hole and shaft are allowed to change within their respective tolerance… Read more Industrial refrigerator with clearance fit, interference fit and transition fit

Cryogenic treatment of industrial refrigerator with metal materials
The method of temperature difference is to use heating hole or cooling shaft to form clearance fit through thermal expansion and cold contraction. After the temperature returns to normal temperature, the clearance fit is converted into interference fit to meet the specified interference amount and meet the technical requirements. However, for the assembly of large… Read more Cryogenic treatment of industrial refrigerator with metal materials
Low temperature assembly technology in automobile industry
The engine and gearbox need to be assembled at low temperature, which is more convenient and precise than the press in assembly! With the development of cryogenic treatment technology, the lowest temperature of our cryogenic assembly box is nearly – 150 ℃, which provides advanced cryogenic assembly equipment for automobile cryogenic assembly industry. It can… Read more Low temperature assembly technology in automobile industry
Cold assembly method of bushing parts
The cold assembly of bushing parts used in construction machinery is based on the principle of heat expansion and cold contraction of materials, that is, the bushing is frozen first It is the dimension shrinkage of the bushing (changing the interference fit into clearance fit), and then in the process of assembly, the cold assembly… Read more Cold assembly method of bushing parts
Knowledge of Interference Assembly and Application of Industrial Freezer
DefinitionClearance fit, interference fit and transition fit can be formed according to different relative position relations of combined hole and shaft tolerance zone. Among them. A fit with an interference (including a minimum interference equal to zero) is called an interference fit. In this case, the tolerance zone of the hole is under the tolerance… Read more Knowledge of Interference Assembly and Application of Industrial Freezer
