Roller structure and classification

Composition of the drum:

The drum is divided into two types, namely unpowered drive and unpowered conveying roller, also known as free roller. It is composed of cylinder, shaft core, deep groove ball bearing, and bearing mounting bracket. Used for auxiliary rolling operations, without power external force rolling.

The driving roller is usually an electric drum with a built-in motor. Attention should also be paid to a type of roller that can be driven by a reduction motor, such as a sprocket, synchronous pulley, etc. Its structure and power are basically the same, and can only be equipped with a built-in motor or components that can be driven by a reduction motor, such as a sprocket or synchronous pulley.

Steps for selecting rollers:

When selecting rollers, attention should be paid to weight differences. We should choose the diameter and length of the roller and the length of the roller. We should also pay attention to producing according to user requirements. Generally speaking, the width of the goods+50mm. The company has different types, lengths, and requirements for heavy conveyor rollers. A suitable profile roller should be selected in a fixed environment, such as the selection of stainless steel or plastic steel rollers in humid environments.

When selecting a drum, it is important to pay attention to the turning radius when there is a turning roller to ensure smooth material transportation. In order to ensure balanced transportation of goods, attention should be paid to the contact between the three rollers and the conveyor whenever necessary. Afterwards, for soft bags, additional pallets should be added for transportation if necessary.

Roller classification:

According to unpowered, unpowered rollers and powered rollers include straight roller and tapered roller types; It should also be noted that according to the impact of power drum drive, it can be divided into two types: active sports type and product release type; Then, it should be noted that payment can be divided into circular belt drive (slot) belt drive and chain drive (friction) (chain theory) based on the driving effect of the power drum; According to the variety of bearings, special precision bearings, special stamped bearings, bearing seats, and including steel engineering plastic seats.
