Technical Data Coupling Handling
Nylon Chain Coupling Handling
The standard type and E type chains (made of polyacetal) can be damaged when the joint pin is attached or removed at low ambient temperature.
Always attach and remove the joint pin of these types at an ambient temperature of at least 10°C, or first warm the area around the joint using a hairdryer or the like.
Mounting
-
1. Bring the sprocket side faces into contact with each other and correct their angular misalignment. Correct the angle so that tooth side face dimension T is equal around the circumference.
-
2. Bring the sprocket side faces into contact with each other and correct their parallel misalignment. Place a straight edge on the tooth faces and adjust to eliminate any misalignment of the tooth bottoms.
-
3. Separate the sprockets by a distance equal to dimension S, and wrap the chain onto them.
-
4. Insert the joint pin into the hole in the chain. Insert the pin straight to ensure the load on it is evenly distributed, and connect the chain. If the pin becomes bent during insertion, remove it and use a spare pin to redo the connection.
After connecting the chain, fasten the sprockets to the shafts with set bolts or similar fasteners.
| Type | Allowable angular misalignment (Angular Misalignment )θ |
Allowable parallel misalignment (Parallel Misalignment )ε |
Allowable end play (Axial Displacement )S |
|---|---|---|---|
| Standard type | 0.5° | 0.1mm | See table of dimensions |
[Ambient operating temperature range ]
Standard type ：-5℃～+60℃
[Notes for use ]
Procuring and installing a safety cover is recommended to protect against flying fragments if the chain of a Tsubaki coupling breaks.
Removal
- 1. First check that there is no torque being applied to the coupling.
- 2. Next, remove one of the chain’s pins (any pin), and remove the chain and sprockets.
