Differences Between Sleeve Roller Chains and Non-Sleeve Roller Chains
1. Sleeve Roller Chain
- Power Transmission Element: The power transmission element of a sleeve roller chain is the metal chain plate, while the engaging element is the roller.
- Linking Elements: The linking elements consist of the sleeve and the pin shaft.
- Features:
- The sleeve roller chain has a larger pressure-bearing surface in the hinge, making it more resistant to wear.
- During engagement, the roller (engaging element) rotates, which helps in smooth operation and reduces friction between the chain and sprocket.
2. Non-Sleeve Roller Chain
- Power Transmission Element: The power transmission element is also the metal chain plate, with the engaging element being the sleeve.
- Linking Elements: The linking elements are again the sleeve and the pin shaft.
- Features:
- In a non-sleeve roller chain, the engaging element (the sleeve) does not rotate during engagement, which means there is more direct contact between the sleeve and the sprocket, leading to different wear patterns.
- This type of chain may be less efficient in terms of wear resistance compared to sleeve roller chains.
Summary
- Sleeve Roller Chains: The rollers rotate during operation, providing better wear resistance and smoother engagement.
- Non-Sleeve Roller Chains: The sleeve itself engages directly without rotation, which can lead to increased wear and less smooth operation compared to sleeve roller chains.
Both types of chains have their own specific use cases depending on the required durability, load capacity, and operational efficiency.
