Poli and coupling
Foley or pulley is an industrial part that is used to transfer power or speed in mechanical mechanisms.
This industrial piece does this transfer of power and speed with a belt. Foleys do what they do.
Foleys can be selected with one belt, 2 belts, 3 belts and even several belts to ensure the desired speed and power transmission.
Foley and belt are mostly used in lower forces and high revs. In low periods and high powers, gears and chains are preferred.
At high speeds and high powers, where it is not possible to use gears and chains (due to high speed), multi-belt pulleys with a large number of belts are used.
coupling
Couplings are a means of shaping the motor and the pump shaft. Couplings are in fact for centrifugal motors, centrifugal pumps, pump close (pomp close) where the shaft and motor are in a fraction are connected by the coupling.
It should be noted that if the selected coupling is not of good quality, there is a possibility of damage to the encoder or motor. The primary purpose of the couplings is to connect the two rotating parts while allowing them to deviate. Give.
By carefully selecting, installing and maintaining couplings, you can save a lot of maintenance costs and downtime.
To select a coupling from Equation 1-1:
1-1
Ts(N.M)=9550×(P(KW)/n(1/min))
In this formula, P is the power of the motor in terms of kilowatts and n rpm of the motor. (Number of turns on per hour) Read St and Sz and use Equation 1-2. According to the value of Total in the coupling selection table, the coupling is selected.
1-2
Total=Ts×St×Sz

Rotex coupling material
Rotex coupling material is made of high-quality cast iron and all its parts are machined which does not vibrate the system at high speeds.
The intermediate interface (Spider) of the Rotex coupling is also made of high quality polyurethane (TPU) material and its prominent features include the name of Bagheri hacked on it.
Rotex couplings withstand small torques and light weight and are ideal for absorbing vibrations and shocks of the system. One of the characteristics of Rotex Couplings Polyurethane Couplings is working at temperatures between -40 to 90 degrees in normal conditions and temperatures of -50 to 120 degrees in short times. These polyurethanes work well in oils and petroleum products, for tropical environments and Sultry are also ideal.
KB coupling
KB couplings in standard design mode are made of flexible shock absorbers made of synthetic rubber. KB coupling body is made of gray cast iron and they are used for all types (piston pumps, piston compressors, etc.).
Couplings (KB) come in a variety of sizes that can be used to transmit torque up to 2800 Nm.
HRC coupling
The HRC coupling consists of 2 cast iron halves that are connected to the shafts using either a conical bushing mounted on a hub (H Flange) or a cover (F Flange).
Between the two halves is a rubber “spider” that acts as a shock absorber. The job of this rubber part is to absorb vibrations and vibrations caused by the activity of industrial machines.
HRC connections allow limited parallel deflection (0.5 mm) and axial misalignment (1.5 mm). Can be used in shafts with conical bushing up to 90 mm hole or shaft up to 130 mm in case of key deviation.
UCC Couplings
UCC 1000-bar couplings or cast iron-Teflon couplings are used for various purposes. Hydraulic industries and work units generally use 1000-thrombus couplings.
Coupling rubber
The main task of the coupling rubber is to connect two separate parts that have vibration movements, which does not allow the movement or transmission of vibration between them, and therefore the selection, installation and maintenance of standard and quality coupling rubber is economical. Save on maintenance and no depreciation.
There are many important parameters in the manufacture of coupling rubber. In fact, the environmental constraints in which the coupling rubber is used are very important.
For example, the coupling used in the automotive industry is different from the coupling used in the shipbuilding industry. Due to special environmental conditions, it must be designed and built for the same industry.
The torque speed that this coupling must withstand or transmit is also very important. Another important point is the maximum allowable deviation and looseness and the material of the coupling materials in its design and construction.
It should always be easy to connect and remove the coupling rubber. The coupling must always provide the possibility of misalignment between the rotating axis and the shaft, while the coupling must not have a detachable or throwing piece. Improper installation or incorrect choice can be considered as the main reasons for the failure of couplings. Coupling failure causes abnormal noise and the sound of impact or vibration and vibration or leakage of oil can occur.
Coupling rubber is used in places where it is necessary to transmit force and at the same time to neutralize the shocks caused by starting or sudden stop of the equipment.
