Analyze the design principle of unpowered roller conveyor roller

As the intelligent manufacturing field of the industrial 4.0 concept, the non-powered roller conveyor is an important solution for in-plant logistics in intelligent manufacturing. It is very common and essential when we make intelligent manufacturing solutions for enterprises; For those who are interested in the design of the overall solution for Industry 4.0 will help, this chapter we introduce "Roller conveyor line design - no power roller":

First, the characteristics of the powerless roller conveyor:

1. Configure semi-precision bearings specially developed, and the drum rotation is lighter and more flexible.

2. The unpowered roller has a larger clearance than the precision ball bearing, and the ability to withstand impact loads is superior to other series.

3. The no-power roller has a slightly larger running noise than the precision ball bearing.

4, no power roller full anti-static design.

5. The non-powered roller has low requirements on the use environment, and both high and low temperatures can operate well.

6. The non-powered roller is not suitable for belt conveyor roller and belt friction conveying.

7, no power roller for temperature: -20 ° C ~ +80 ° C.

Second, the parameter configuration of the non-power roller conveyor:

1. Bearing assembly: semi-precision bearings.

2. Main materials: steel and galvanized.

Third, the non-power roller conveyor roller is classified into spring press-in type, internal thread type and milled flat type; when designing, the length of the drum is generally selectable, that is, the manufacturer can according to the length of our design. , give customization.

Fourth, the material of the powerless roller:

The materials of the unpowered roller tube are generally: steel, galvanized, stainless steel; when designing the roller conveyor line, we must fully consider the factors of these materials, and have different choices in different occasions and different products, such as the environment. Moisture, high temperature (low temperature) environment, corrosive environment, large friction coefficient during transportation, etc.

Five, the size of the powerless drum:

Unpowered drum size We generally include pipe diameter, shaft diameter, drum length (body + sprocket), pipe diameter, and the size of the drive belt. We should fully consider these parameters when designing. For example, the design of the drum length should be defined according to the size of the items we need to transport. The wall thickness of the pipe should be considered considering the weight and placement of the articles we transport, if the product It is heavy or it is heavy. We choose a roller with a small wall thickness to avoid crushing. The length of the drum is customizable when we design it, and suppliers generally offer this type of service.
