Easy operation conveyor trough return bending roller

Roller introduction:

Our company has been attaching importance to the design and manufacturing process of carrier roller.The current carrier roller,having drawn on experience from German company PRECISMCECA and Japan IHI and American United Continental Holdings,is a good design of high quality and unique features.We use stamping bearing pedestal in producing bearing,seamed steel pipes and KA-series bearing with backlash and with waterproof and dustproof seals.We also use double retaining ring in axial direction setting and lithium-based No.3 lubricating grease with strong performance of aging resistance.This kind of carrier roller features rational construction,steady and reliable performance,small resistance to rotation,smooth operation and good water and dust proof performance. 

Pipe blanking is conducted by differential gear feed tube-cutting machine tool of domestic advanced level.Double-end bore is used in pipe procession.Work piece is chucked one time and lathe work is done to ensure the coaxiality of bore diameter of both ends and size and precision of the mould.Stamping bearing pedestal chooses domestic 08F or 08AL steel plate which experiences cold rolling and then recrystallization.There are 13 processes from blanking to moulding.The assembling of carrier roller adopts technology of assembling before welding and is conducted on double-end welding machine.The welding of bearing pedestal and pipe is conducted at the same time.CO2 gas automatic protection welding is adopted. 

Roller Major technical parameters:

Roller resistance to rotation

The amount of radial run-out

 Roller Axial load

Roller'S Axial float

Under the impact of axial load of 500N,the axial float figure≤1.2mm

Roller Dropping intensity

After experiments of horizontal and vertical drop of carrier roller,the following requirements should be met:

1. All components and welded joints cannot be damaged or taken apart;
2. Axial displacement of roller carrier after falling should be not more than1.2mm;
3. The body and bearing of carrier roller should never be loosing;
4. The resistance to rotation should be not more than1.5 times of the figure stipulated in table 1.

Roller Sealability in water

After revolving at the rate of1450t/min for 24 hours in water,the water inflow of the carrier roller with non-contact seal device is not more than150g.

Roller Life span

When reinforced service life of carrier roller is converted into the actual service life,the time span is no less than 20000h.The damage rate of carrier roller is no larger than10%. 

Roller Range of application

Our product is widely used in such surrounding as underground coal mine and that with severe open-air dust and high corrosivity.These places include mines,power plants,steel mills,stone factory,cement plant,coking plant,coal washing plant,saltworks,soda ash factory,chemical fertilizer plant and wharfs.
