Bushed Coupling is a mechanical device that connects shafts through elastic sleeves, mainly used to connect two shafts or shafts with other rotating components, transmit torque, and compensate for a certain degree of axial, radial, and angular deviation. Compared with rigid couplings, Bushed Couplings have the advantages of buffering, absorbing vibrations, and compensating for deviations, which can effectively protect the transmission system from damage caused by impact loads.
A typical bushing coupling consists of the following main components:
Wheel hub section: usually two, installed on the driving shaft and driven shaft respectively
Elastic bushing: located between two wheel hubs, it is the core component of the coupling
Connecting bolt: used to fix the wheel hub and liner
Protective cover: Some models are equipped with protective covers to prevent dust from entering and ensure safety
The Bushed Coupling achieves the following functions through the deformation of the elastic sleeve:
Torque transmission: transmitting rotational power through the shear and compression deformation of the lining
Deviation compensation: Elastic deformation allows for a certain degree of axial, radial, and angular deviation
Shock absorption and buffering: absorbing and attenuating system vibrations and impact loads
Insulation protection: Some lining materials can provide electrical insulation function
According to the different structural forms and lining materials, lining couplings can be divided into the following common types:
Plum shaped bushing coupling
Using polyurethane or rubber plum blossom shaped pads
Simple structure, easy disassembly and assembly
Suitable for small and medium power transmission systems
Bushed pin type coupling
Using rubber or polyurethane sleeves as elastic components
Connect the two halves of the coupling through a column pin
Strong carrying capacity and good compensation performance
Diaphragm type bushing coupling
Using metal or composite membrane as elastic element
Seamless transmission, suitable for high-precision applications
Maintenance free, long service life
Tire type liner coupling
Circular rubber tire structure
High compensation capability and good shock absorption effect
Suitable for large deviation and heavy load situations
Shock absorption performance: effectively reduces the vibration and noise of the transmission system
Compensation capability: can compensate for radial deviation of 0.5-3mm and angular deviation of 1-5 °
Insulation performance: Some lining materials can provide electrical insulation up to 10kV
Easy maintenance: Most types only require regular inspection of the wear of the lining
Economy: Compared to other elastic couplings, the cost is lower
Choosing a suitable bushing coupling requires consideration of the following factors:
Transmitting torque: Calculate the required torque capacity based on system requirements
Speed range: Ensure safe operation of the coupling at rated speed
Deviation type and magnitude: Select compensation capability based on the alignment of the shaft system
Environmental conditions: Consider factors such as temperature, humidity, corrosiveness, etc
Installation space: Determine the coupling size based on the available space
Bushed Couplings are widely used in the following industries and equipment:
General machinery: pumps, fans, compressors, etc
Material transportation: conveyors, elevators, etc
Construction machinery: excavators, cranes, etc
Power generation equipment: generators, turbines, etc
Rail Transit: Locomotive Drive System
Shipbuilding industry: propulsion system transmission
Installation requirements:
Ensure that the shaft end clearance meets the requirements
The deviation in alignment is within the allowable range
Tighten the fastening bolts to the specified torque
Daily maintenance:
Regularly check the wear of the lining
Check the tightening status of bolts
Pay attention to abnormal vibrations or noise
Regularly lubricate according to the usage environment (if applicable)
Replacement standard:
The lining shows obvious cracks or permanent deformation
Significant decrease in elasticity performance
The wear amount exceeds the allowable value
As an important component of mechanical transmission systems, the performance of Bushed Couplings directly affects the operational efficiency and reliability of the entire equipment. The correct selection, installation, and maintenance of Bushed Couplings are of great significance for extending the service life of equipment and reducing maintenance costs.
