Product Description
57150152-670 CHINAMFG Coupling Element OEM Screw Air Compressor Spare Parts 88290003-326
The composition of the coupling parts:
There are 2 types of couplings for screw air compressors: Rubber pin type and flexible (diaphragm type) couplings.
1.The rubber pin coupling consists of 2 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 2 half couplings, connecting barrels, transmission gaskets and screws. The 2 half-couplings of this coupling are tested for dynamic balance, and the relative positions are fixed during installation.
The coupling is an important part that transmits the power of the motor to the active rotation of the compressor. Due to the high speed of the screw air compressor, the requirements for the installation accuracy (coaxiality) of the coupling are also high. Improper installation of the coupling will not only cause the machine to run erratically and increase noise, but also cause abnormal damage to the rotor, main bearing, thrust bearing and shaft seal, resulting in overhaul of the main engine.
Coupling Features
- Good starting performance can change the load starting of the motor to no-load starting, so as to realize the soft starting of the working machine, reduce the current during starting and reduce the starting energy consumption.
- Save electric energy and equipment cost, which can solve the unreasonable situation of the big horse-drawn trolley with load starting machine, save the motor capacity, improve the power factor and motor efficiency of the grid, reduce reactive power loss, save electric energy, and simplify the motor starting equipment and reduce equipment cost.
- The transferred torque can be adjusted, easy to achieve overload protection.When the working machine is overloaded or jammed, the steel ball type safety coupling will slip automatically, which can prevent the motor from burning out and other parts damage.
- Except for the starting and braking stages, the main and driven parts of the steel ball safety coupling have no speed difference, no friction loss and high transmission efficiency.
- Nonmetallic elastic elements are adopted in the steel ball type safety coupling, which can compensate the offset of the linked 2 axes within a certain range, with a small amount of buffering and damping.
- Reliable operation, stable performance, convenient installation, disassembly and maintenance.
Determining the right type of flexible coupling starts with the following analysis of the application:
- Prime mover type (motor, diesel engine, etc.) of the drive side of the system
- Actual horsepower and/or torque requirements, not prime motor-rated horsepower (note the range of variable torque caused by periodic or unstable loads, worst-case starting loads,
- Drive system inertia related to prime mover inertia (data available from equipment supplier)
- vibration, linear and torsional vibration (experienced supplier or consultant can help you evaluate vibration) shaft-to-shaft deviation;
- Note the degree of Angle offset (axis is not parallel) and parallel offset (distance between axis centers when axes are parallel but not aligned);
- Also note whether the drive/driven units share the same floor axial (inside/outside) axial motion,
- whether they share distance (the distance between the drive end and the driven axis), and any other space-related restrictions.

Potential Causes of Failure in Elastomeric Couplings and Preventive Measures
Elastomeric couplings are generally robust and reliable components, but certain factors can lead to potential failures. Understanding these causes can help implement preventive measures to ensure optimal performance and longevity. Here are some common causes of failure and their prevention:
1. Overloading:
Exceeding the specified torque or power ratings of the elastomeric coupling can lead to premature failure. Preventive measures include selecting a coupling with appropriate torque and power ratings for the application and avoiding sudden load increases or over-torque conditions.
2. Misalignment:
Misalignment between the shafts connected by the coupling can result in increased stresses on the elastomeric element, leading to wear and failure. Regular alignment checks and adjustments can help prevent excessive misalignment.
3. Environmental Factors:
Harsh environmental conditions, such as extreme temperatures, chemicals, moisture, or corrosive substances, can degrade the elastomeric material over time. Choosing couplings with suitable materials and environmental protection can mitigate these effects.
4. Fatigue and Ageing:
Elastomeric materials can experience fatigue and aging due to cyclic loading and prolonged use. Regular inspection and replacement of couplings based on manufacturer recommendations can prevent failures caused by material deterioration.
5. Improper Installation:
Incorrect installation can lead to stress concentrations or uneven loads on the coupling, causing premature failure. Proper installation procedures, including following manufacturer guidelines, using appropriate tools, and ensuring proper shaft alignment, are essential to prevent installation-related issues.
6. Excessive Vibrations:
Excessive vibrations in the machinery can accelerate wear on the elastomeric coupling. Addressing the root causes of excessive vibrations, such as unbalanced loads or misaligned components, can help extend the coupling’s lifespan.
7. Contaminants:
Foreign particles, dirt, or debris can infiltrate the coupling and lead to abrasive wear or reduced flexibility. Regular cleaning and maintenance can prevent these issues.
8. Poor Maintenance:
Lack of routine inspection and maintenance can allow minor issues to escalate into major problems. Implementing a maintenance schedule that includes regular inspections, lubrication, and replacement of worn components can help identify and address potential failures before they occur.
By proactively addressing these potential failure causes, industrial operators can ensure reliable and efficient performance of elastomeric couplings, minimizing downtime, and reducing maintenance costs in the long run.
Reducing Vibrations and Noise with Elastomeric Couplings
Elastomeric couplings are designed with inherent damping properties that enable them to effectively reduce vibrations and noise in rotating machinery. Here’s how elastomeric couplings achieve this:
1. Vibration Absorption:
Elastomeric materials have the ability to absorb and dissipate vibrational energy. When a rotating machinery system experiences torsional vibrations, the elastomeric coupling’s flexible element absorbs these vibrations, preventing them from propagating through the system. This dampening effect helps to minimize the transmission of vibrations to the connected equipment, reducing wear and fatigue on components.
2. Shock Load Reduction:
Elastomeric couplings can also absorb shock loads that occur during sudden starts and stops. When the machinery experiences abrupt changes in torque, the elastomeric material cushions the impact, protecting the machinery from potentially harmful shock loads.
3. Misalignment Compensation:
Machinery misalignment can lead to vibrations, noise, and premature wear. Elastomeric couplings are designed to accommodate various types of misalignment, including angular, parallel, and axial misalignments. By flexing and compensating for misalignment, the coupling reduces stress on the connected machinery, further minimizing vibrations.
4. Damping of Resonance:
Resonance is a phenomenon where the natural frequency of the rotating machinery coincides with an external force, leading to amplified vibrations. Elastomeric couplings help dampen resonance by absorbing and dissipating the energy, preventing resonance-related issues and reducing noise.
5. Electrical Isolation:
Elastomeric couplings made from electrically insulating materials provide electrical isolation between connected shafts. This isolation prevents the transmission of electrical currents or interference between the machinery components, which can contribute to noise and signal disturbances.
By effectively reducing vibrations and noise, elastomeric couplings contribute to smoother and quieter operation of rotating machinery. This leads to benefits such as improved equipment reliability, reduced maintenance costs, and increased operator comfort in industrial settings.
However, it is important to select the appropriate elastomeric coupling based on the specific requirements of the machinery and application. Factors such as torque, speed, misalignment, and environmental conditions must be considered to ensure that the coupling can effectively mitigate vibrations and noise while providing reliable power transmission.
How to Select the Right Elastomeric Coupling for a Particular Application
Selecting the appropriate elastomeric coupling for a specific application involves considering several key factors to ensure optimal performance, efficiency, and reliability. Here’s a step-by-step guide to help you make the right choice:
1. Load Requirements:
Start by determining the torque and power requirements of your application. Consider both the steady-state and peak loads to select a coupling that can handle the maximum expected load without exceeding its torque capacity.
2. Misalignment Tolerance:
Evaluate the expected misalignment between the connected shafts. Elastomeric couplings are excellent at compensating for small misalignments, but for larger misalignments, special designs or alternative coupling types may be more suitable.
3. Speed and RPM:
Understand the rotational speed (RPM) at which the coupling will operate. High-speed applications may require more rigid couplings to avoid dynamic issues, while low-speed applications can benefit from the damping effect of elastomeric couplings.
4. Environmental Conditions:
Consider the environmental factors that the coupling will be exposed to, such as temperature, humidity, chemical exposure, and presence of abrasive particles. Choose a coupling material that can withstand these conditions without compromising performance.
5. Space Constraints:
If you have limited space in your application, look for compact elastomeric couplings that can fit within the available area without sacrificing performance.
6. Electrical Isolation:
In applications where electrical isolation is required, select an elastomeric coupling made from an electrically insulating material.
7. Maintenance:
Consider the maintenance requirements of the coupling. Elastomeric couplings are generally low-maintenance, but if your application involves harsh conditions, you might need to inspect and replace the coupling more frequently.
8. Manufacturer Recommendations:
Always consult with the coupling manufacturer for their recommendations and technical specifications. Manufacturers can provide valuable insights and guidance based on your specific application requirements.
9. Cost Consideration:
Compare the cost of different elastomeric couplings while keeping in mind their performance and longevity. Striking the right balance between cost and quality is essential.
By carefully evaluating these factors and matching them to the characteristics of available elastomeric couplings, you can select the most suitable coupling for your particular application. Proper coupling selection ensures reliable power transmission, longer equipment lifespan, and reduced downtime in industrial systems.
