Brass Couplings Meet Machine Technical Requirements

Brass coupling between the two axes of the deviation and brass coupling end face clearance, should meet the technical requirements of the machine. If there is no requirement, should meet the following requirements: half of the brass coupling end should be in close contact, the two axis of the deviation: Plastic Brass Push in Coupling radial displacement should not be greater than 0.03 mm, axial tilt should not be greater than 0.05 / 1000.

Other rigid brass couplings

Common types: sleeve brass coupling, shell brass coupling, tight hoop shell brass coupling, flange shell brass coupling, and so on.

Installation and maintenance requirements: the use of brass coupling drive machine, brass coupling two-axis alignment and brass coupling end face clearance, should meet the technical requirements of the machine. If there is no requirement, should meet the following requirements: half of the brass coupling end should be in close contact, Plastic Brass Push in Coupling the two axis of the deviation: radial displacement should not be greater than 0.03 mm, axial tilt should not be greater than 0.05 / 1000.

Flexible brass coupling, slider brass coupling:

Common types:

Cross slider brass coupling, slider brass coupling and so on.

Installation and maintenance requirements: the use of brass coupling drive machine, brass coupling two-axis alignment and brass coupling end face clearance, Plastic Brass Push in Coupling should meet the technical requirements of the machine. If not required, shall comply with the following provisions: Cross slider Brass coupling The relative displacement of the two shafts is not more than 0.01d +0.25 mm (d is the shaft diameter), permissible relative angular displacement of 30', When the diameter is not more than 190 mm, Plastic Brass Push in Coupling it shall be O. 5 ~ O. 8 mm; when greater than 190 mm, it should be 1 to 1.5 mm.

Brass coupling installation process:

Cold assembly method: direct assembly method for the brass coupling and the shaft with the corresponding gap can be cleaned in the clean with the surface, Plastic Brass Push in Coupling apply grease directly installed.

The press fit method is not a great fit for the transition fit and the interference amount, or the special requirements (such as the protection of the other parts of the package) can be pressed, but need to press the device.

Hydraulic Assembly Method: Plastic Brass Push in Coupling This is an ideal method of assembly, but must be used in response to the design and manufacture of other components in advance.

Hot assembly of brass couplings: Hot assembly of couplings is often used in the installation of heavy equipment such as large motors, compressors and rolling mills, since the coupling and shaft in such equipment are usually fitted with interference fit Connected together.

The assembly method of the interference joint is: pressure into the assembly, low temperature cold assembly and hot sets, such as assembly. In the installation site, Plastic Brass Push in Coupling the main use of thermal assembly method, because this assembly method is relatively simple, can be used for large diameter (D> 1000mm) and the larger amount of interference parts). Pressure into the assembly method for light and medium-sized static fit, and the need for presses and other mechanical equipment, it is generally only used in the factory. Cold shrink assembly method generally use liquid nitrogen as a cold source, and the need for a certain insulated containers, it can only be used in conditional conditions. The following describes the heat assembly method.

The basic principle of the heat assembly: the essential principle of the heat assembly is to heat the package (hole), so that the diameter of a expansion with a matching value, Plastic Brass Push in Coupling and then loaded into the package (shaft), to be cooled, the machine will reach Need to combine strength.

 In fact, the heating expansion value must be greater than the matching value in order to ensure the smooth installation without causing the cooling process due to the cooling of the package, the shaft and hole stuck serious accident. At the same time, in order to ensure a greater engagement force - bonding strength, the thermal assembly of the bonding surface to be processed, but not too smooth, because a certain surface roughness (generally Ra3.2), without axial movement Is flattened, after cooling, will make the internal and external mechanical bonding strength, can pass the torque is also larger.

Determination of heating temperature When the workpiece material is certain, the minimum heating temperature of the inclusion element depends on the interference of the mating surface and the required assembly gap.
