A flexible drive coupling is a device that transmits torque between two rotating shafts while allowing for some misalignment and vibration absorption. They are designed to accommodate minor shaft misalignments, reducing stress on connected equipment and potentially improving overall system efficiency and longevity. Flexible couplings can be made from various materials, including elastomers and metals, each with its own advantages and disadvantages.
flexible drive coupling Detail
| Product Name | Flexible drive coupling |
| Product Material | The core material is low-cost and moderately strong carbon steel (such as Q235, 45 steel) or high-strength and wear-resistant alloy steel (such as 40Cr, 35CrMo) or clean environment stainless steel (such as 304, 316). |
| Product Process | The rigid components of metal parts are processed by turning/milling to form shaft holes, keyways, flange surfaces and other structures. Alloy steel (such as 40Cr) needs to be tempered (quenching + high temperature tempering) to improve the comprehensive mechanical properties. |
| Surface Treatment | Options include black coating, zinc plating, phosphate coating and Dacromet coating. |
| Customizable Products | Gears / Sprockets / Worms / Shafts / Rack Bars / Bevel Gears, etc. |

What is a flexible drive coupling?
A flexible drive coupling is a mechanical device used to connect two shafts and transmit power in a mechanical transmission system. Its core feature is that the connection is achieved through elastic elements.
What is the main purpose of flexible drive coupling?
Flexible drive couplings are mainly used to connect two shafts in mechanical transmission systems to achieve power transmission. They rely on elastic elements to compensate for the radial, axial and angular deviations of the two shafts during installation or operation to avoid stress concentration.
What are the advantages of flexible drive coupling?
The main advantage of the flexible drive coupling is that it can effectively compensate for the radial, axial and angular deviations of the two shafts with the help of elastic elements, reducing the installation accuracy requirements; the excellent shock-absorbing and buffering performance can absorb impact loads and high-frequency vibrations, reducing equipment wear and noise.
