Nylon chain coupling (wrap type coupling)
- This is an economy type with a resin chain such as polyacetal wound around the sprocket.
- An economical flexible coupling with a resin chain made of polyacetal, a typical engineering plastic, wound around a sprocket.
is. - ・Applicable shaft diameter: 9.5Φmm to Φ55mm
- Torque range: 6.9 to 255 Nm
Standard type: Structure and features
-
・Can be installed with a short axis distance
The structure is simply two sprockets connected by a nylon chain, so it can be installed even when the distance between the two shafts is short, allowing for a compact overall device.
-
- Easy to put on and take off as it is wrapped around the body
Assembly is easy; just wrap the nylon chain around the outer circumference of the sprocket and insert the coupling pin.
In addition, when performing maintenance on the equipment, the connection can be cut off without moving the drive or driven machine.
-
・Torque can be increased without changing the overall length
Increasing the number of teeth on the sprocket increases the torque transmitted by the coupling, allowing you to increase the size of the coupling without changing the center distance of the device.
