pin coupling belongs to mechanical transmission accessories material cast iron cast steel to connect two shafts and transfer

These are column pins couplings, which belong to mechanical transmission accessories. They are generally made of materials such as cast iron and are widely used in fields such as mining machinery and mechanical manufacturing. They play a role in connecting two shafts and transmitting torque. It achieves the connection of the two parts through the column pins and has the ability to buffer, reduce vibration, and compensate for the relative displacement of the two shafts. The figure shows a column pins coupling. It is a commonly used component in the mechanical field. From the structure, it is composed of several disk with holes connected by column pins. The working principle is to rely on the column pins to transmit torque, achieving the connection and transmission of the two shafts.

In terms of performance, it possesses certain buffering and damping characteristics, which can reduce vibration and impact in the transmission system, protecting the equipment. It can also compensate for the relative displacement generated between the two shafts during installation and operation, enhancing the stability and reliability of the transmission. This technology is widely applied in a variety of mechanical equipment transmission systems, such as fans, pumps, and machine tools.The object in the picture is a coupling. Couplings are commonly used components in mechanical transmission, used to connect two shafts and transfer torque. They come in various types, and the one in the picture might be a clamp-type coupling, which transfers power by means of clamp-like structures that engage with each other. They have the ability to compensate for the relative displacement of the shafts, buffer and reduce vibration, and reduce vibration in the transmission system, which makes them widely used in various mechanical equipment, such as in the drive systems of fans, pumps, and machines. They can ensure the stable operation of the equipment.
