Product Description
The lower return self-aligning idler:The differences between the lower-aligning idler set and the upper-aligning idler set are as follows:
I. Structural differences
- Position and installation method:
- The upper-aligning idler set is usually installed above the conveyor belt and corrects the deviation of the conveyor belt by adjusting the angle of the idlers.
- The lower-aligning idler set is generally installed below the conveyor belt, and its adjustment method is different from that of the upper-aligning idler set.
- Adjustment mechanism:
- The adjustment mechanism of the upper-aligning idler set may be relatively more complex. Usually, the angle of the idlers needs to be adjusted manually or automatically to adapt to different deviation situations.
- The adjustment mechanism of the lower-aligning idler set may be simpler and more direct, and may be adjusted by gravity or other mechanical means.
II. Performance differences
- Centering effect:
- The upper-aligning idler set usually has a more proactive role in correcting the deviation of the conveyor belt. It can respond quickly to the deviation situation and apply a larger lateral force by adjusting the angle of the idlers to make the conveyor belt return to the correct position.
- The centering effect of the lower-aligning idler set may be relatively milder. It mainly adapts to the deviation of the conveyor belt by adjusting its own position and has a smaller lateral force on the conveyor belt.
- Scope of application:
- The upper-aligning idler set is suitable for occasions where the conveyor belt deviation is relatively serious or needs to be corrected quickly. It can adjust the running direction of the conveyor belt in a large range and has a good effect on high-speed and large-capacity conveying systems.
- The lower-aligning idler set is suitable for occasions where the deviation degree is relatively light or the adjustment accuracy requirement is not high. It is usually used in some small conveying systems or occasions where the running stability requirement is not high.
III. Maintenance differences
- Maintenance difficulty:
- Due to its relatively complex structure and more adjustment mechanisms, the upper-aligning idler set may be slightly more difficult to maintain. It is necessary to regularly check the flexibility and reliability of the adjustment mechanism to ensure its normal operation.
- The structure of the lower-aligning idler set is relatively simple, and maintenance may be easier. Mainly check the wear condition of the idlers and the working state of the adjustment mechanism.
- Maintenance frequency:
- Due to its important role in correcting deviation, the upper-aligning idler set may require more frequent maintenance and inspection to ensure its stable performance.
- The maintenance frequency of the lower-aligning idler set may be relatively lower unless there are obvious failures or wear conditions.
In short, there are certain differences between the upper-aligning idler set and the lower-aligning idler set in terms of structure, performance, and maintenance. When choosing to use them, a reasonable choice needs to be made according to the specific requirements of the conveying system and the working environment.
- Roller/idler introduction:
Rollers/idlers are important components of belt conveyors. Their function is to effectively support the conveyor belt and the materials carried on the conveyor belt, ensuring the normal operation of the conveyor. The diameters of idlers have domestic standards and foreign standards.
Domestic standards:Φ63,Φ76,Φ89,Φ108,Φ133,Φ159,Φ194,Φ219;
Foreign standards: Φ 89,Φ102,Φ114,Φ 127,Φ 139,Φ152,Φ 165,Φ 178 and other specifications.
