MengziLx Elastic Pin Coupling

The Lx elastic pin coupling uses several non-metallic elastic pins inserted into the flange holes of the two coupling halves, thereby connecting the two halves via these pins. This coupling boasts a simple structure, is easy to manufacture, and allows for convenient installation, removal, and replacement of the elastic elements without requiring the two coupling halves to be moved.

Product Description

Product Features
The Lx elastic pin coupling uses several non-metallic elastic pins inserted into the flange holes of the two coupling halves, thereby connecting the two halves via these pins. This coupling boasts a simple structure, is easy to manufacture, and allows for convenient installation, removal, and replacement of the elastic elements without requiring the two coupling halves to be moved.

Application scenarios
Suitable for transmission shaft systems connecting two coaxial shafts, this component features compensation for relative displacement between the two shafts and general vibration-damping performance. Its operating temperature range is -20°C to +70°C. The structural configuration is shown in Figure 7.1, and the technical parameters and main dimensions are listed in Table 7-1.
