CONVEYOR ROLLER

Roller is an important part of COEYOR IDLER Whether the belt conveyor can work properly is closely related to the quality of roller.

The indicators to measure the quality of idlers are as follows:

1. Roller radial run-out quantity (this index directly affects the stability of material transportation.)

2. Axial string momentum (directly affects the service life of rollers)

3. Flexibility ratio  (directly affects the service life of rollers & belt)

4. Waterproofness(directly affects the service life of rollers)

5. Dustproofness(directly affects the service life of rollers)

6. Axial loading capacity(directly affects the service life of rollers)

7. Shock resistance(directly affects the service life of rollers)

8. Rotational resistance(directly affects the service life of belt)

Our company adopts advanced roller structure and standard of belt conveyor in GB as the foundation, has carried on the research and development, introduced a wide range of applications, good environmental adaptability, one-time grease, warranty period no need more grease, contact sealing with waterproof, the service life of 30000 hours under normal working condition, do not need to maintain in  warranty period, It is our QinYi type roller series.

Structure

When designing the roller series, we have considered various factors to make it have the minimum starting torque, high efficiency, long life, the minimum maintenance and the maximum loading capacity. The roller has the ideal static and dynamic balance to ensure high-speed application.

Conveyor Tube & Shaft & Housing

The conveyor tube of the roller shell adopts the special high-frequency welded pipe of the national standard supporting roller, the special machine tool of supporting roller is used for rolling and cutting processing, and the bearing housing is formed by cold plate stamping. The precision grade is ISOM7, which can make the starting torque small.The shell and the bearing housing are welded by CO2 gas shielded automatic welding machine, which makes the overall structural strength high and guarantees good precision, and minimizes the radial imbalance factor.The shaft is cold drawn to ISOH6 to ensure the installation accuracy of the bearing.

Bearing & Seals System

Bearing adopts famous domestic and foreign brand :SKF NSK FAG HRB LYC...

single row radial ball bearing:

4G204 4G205 4G206 4G305 4G306 4G308

In certain temperature environment, even a small amount of water vapor into the roller will make it rust, thus reducing the service life of the roller.In order to prevent this phenomenon, the roller adopts a series of sealing measures.From the outside, an ABS resin craft protective cover fixed on the shaft can prevent particles larger than one millimeter from entering into the roller;There is a galvanized sealing device with low friction in the roller, which can prevent grease from flowing out of the roller and external liquid from entering the roller. The weight of the roller does not increase after 24 hours of operation in water.Install a set of ternary labyrinth seals made of nylon 1010;These protective measures effectively prevent the external atmospheric medium from entering the bearing room.

Grease

The bearing is lubricated with long-acting lithium grease. The grease has good stability in different climates and environments. The amount of grease in the bearing chamber can be used for the warranty period of rollers.

Quality Test

Assembled roller loading test bench,

the rotation time, stir to make grease into the bearing, under a certain speed, the roller of the radial runout and axial string momentum, flexible, waterproof, dustproof performance, the axial loading capacity, shock resistance, rotational resistance index for testing and give qualified conform to the specified value.
