Due to the long
distance belt conveyor, the lower return belt will run off and jump, so the inverted
v shaped idler automatic adjustment control is adopted. At the same time, the
V-shaped roller can play the role of the return roller.
Inverted V type idler
features:
1. The ambient
temperature can operate normally at -10℃ ~ 40℃;
2. Normal service
life of rollers: more than 50,000 hours;
3. Roller rotation
resistance coefficient is less than 3.0N;
4. Roller outer
radial run out: 1.0mm below;
5. Axial displacement
of roller: 0.5mm;
6. Rollers can be
used in coal dust, water, wet environment, with dust, water, corrosion
resistance characteristics.
7. Axial bearing
capacity of roller: 10000N;
8. Roller drop test:
After the drop height of 50cm, the roller parts and welds do not have damage
and cracks, and the rotation is flexible;
9. Roller bearing
seals: non-contact, double labyrinth seal structure;
10. Roller bearing:
special double seal labyri…
