What is an “O” belt conveyor roller?

Features of single/double groove "O" belt conveyor roller:

1、 The "O" belt drive, compared with the chain drive has the characteristics of high running noise, slow conveying speed, etc., widely used in light and medium load box conveyors.
2、Optical ball bearings and plastic inner and outer jackets are designed to form a key bearing assembly, which is not only beautiful but also more and more critical to make the roller run more and more calmly.
3、The design of the plastic end cover at the end of the roller can to a certain extent prevent dust and splash water from damaging the bearings.
4、The groove position can be customized according to the needs.
5、Anti-static design.
6. Temperature limitation: -5℃~+40℃.

Single/double groove "O" belt conveyor roller parameters configuration.

Perhaps because of the many manufacturers on the market to produce rollers, each manufacturer's parameters are also different, we should be based on our own needs in the design of the selection.
1, the load is able to drive the operation of the roller and can withstand the smallest load (never represents the bearing capacity of the roller).
2, power transmission, the load plays a decisive role.
The load capacity of the roller depends on the driving arrangement and the driving capacity of the "O" belt, and the single cargo usually never exceeds 30kg.
Classification of single/double trough "O" belt conveyor roller:

1, single groove "O" belt conveyor roller:
(1) Single groove "O" belt conveyor roller diagram:

(2) Single groove "O" belt conveyor roller transmission mode:
a. The driving force of each roller is transmitted by the "main shaft" independently, compared with the double groove transmission, the torque attenuation is large, and it is used for short-distance conveying, and the length of a single conveying unit can be more than 10 meters.
b. After connecting the segmented "main shaft" through the universal joint coupling, it is possible to realize turning conveyance.
c, "O" belt replacement requires disassembly of the entire drive shaft unit, end maintenance is quite simple.

2、Double groove "O" belt conveyor roller:
(1) Schematic diagram of double groove "O" belt conveyor roller:

(2), double groove "O" belt conveyor roller transmission mode:

a. Agile arrangement, easy installation and maintenance;
b, torque attenuation is slow, a single electric roller can only drive 7~8 active rollers accurately, within a conveying unit, the weight of a single cargo should not exceed 30kg.
c, "O" belt installation requires a certain amount of preload, "O" belt manufacturers are different, the amount of preload will be different (please consult the professional "O" belt suppliers), usually take 5% to 8% (i.e. from the theoretical bottom diameter ring length)
(i.e. subtract 5%~8% from the theoretical bottom diameter ring length).

Dimensions of the conveyor rolls of double grooved "O" belts:

Double groove "O" belt conveyor roller size we usually include pipe diameter, shaft diameter, roller length (body + sprocket), and pipe wall thickness, need to be equipped with transmission belt specifications. We in the design of the time to fully consider these parameters, such as the length of the roller design should be based on the size of the items we need to transport to the definition of the wall thickness of the pipe diameter to consider the weight of the items we conveyed and placed in the way to consider, if the product itself is heavier or placed in the action of the heavier and heavier, we will be the choice of thicker wall diameter of the roller in case of difficult to press the bad.

Double groove "O" belt conveyor roller material:

Double groove "O" belt conveyor roller pipe materials usually have steel, galvanized, stainless steel, aluminum alloy, jacket PVC soft rubber; in the design of roller conveyor line, we should fully consider the factors of these materials, in different occasions and different products have different choices, such as environmental humidity, high temperature (low temperature) environment, corrosive environment, conveying process friction coefficient is higher than the smaller situation and so on. Low temperature) environment, corrosive environment, conveying process friction coefficient is higher than the smaller situation, and so on.
