Rubber Joints Stainless Steel Coupling E30  5.3129 E3 for Kaeser Air Compressor Part 5.3129.0

 

Coupling is a device that connects two shafts or shafts and rotating parts, rotates together in the process of transmitting motion and power, and does not disengage under normal circumstances. Sometimes it is also used as a safety device to prevent the connected parts from being subjected to excessive load, and plays the role of overload protection.

The composition of the coupling parts:

There are two types of couplings for screw air compressors: rubber pin type and flexible (diaphragm type) couplings.
1.The rubber pin coupling consists of two half couplings, flywheel, transmission core and screws. The rubber drive core of this type of coupling is easy to wear and wear, which will cause the machine to move unevenly, which will have adverse effects on the rotor, bearings, and shaft seals. At present, it is gradually replaced by flexible couplings.
2.The flexible coupling is composed of two half couplings, connecting barrels, transmission gaskets and screws. The two half-couplings of this coupling are tested for dynamic balance, and the relative positions are fixed during installation.

The application of screw air compressors is mostly elastic coupling, which is an important part of the connection between the screw air compressor motor and the host. It has the following:

1.High torque rigidity and excellent sensitivity;
2.Maintenance-free, oil-resistant and corrosion-resistant;
3.The elastic action compensates radial, angular and axial deviations;
4.There are mainly two kinds of fixing methods: jacking wire and clamping;
5.The clockwise and counterclockwise rotation characteristics are exactly the same;
6.Zero backlash, can run synchronously;
7.There are aluminum alloy and stainless steel materials to choose from;
8.One-piece metal elastomer.
 

Coupling function:

It is used to connect two shafts together. The two shafts cannot be separated when the machine is running. The two shafts can be separated only after the machine is stopped and the connection is disassembled.

Types of Couplings:

The two shafts connected by the coupling, due to manufacturing and installation errors, deformation after bearing and the influence of temperature changes, etc., will cause changes in the relative positions of the two shafts, which often cannot guarantee strict alignment. According to whether the coupling has elastic elements, whether it has the ability to compensate for various relative displacements, that is, whether the coupling function can be maintained under the condition of relative displacement and the purpose of the coupling, the coupling can be divided into rigid couplings. Flexible couplings and safety couplings.
 

 

Coupling performance requirements:

1.Portability. The mobility of the coupling refers to the ability to compensate for the relative displacement of the two rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation, and deformation under load all place requirements on portability.
2.Buffering. For occasions where frequent load starts or working load changes, the coupling needs to have elastic elements for buffering and vibration damping to protect the prime mover and the working machine from being damaged or not damaged.
3.Safe, reliable, with sufficient strength and service life.
4.Simple structure, easy to assemble, disassemble and maintain.
