Roller supports of conveyor belts
Special devices of conveyor belts called “roller bearings” are special devices for the production of which high-quality and high-strength metal is used. The main role played by roller bearings in the construction of conveyor equipment is the reliable maintenance of the conveyor belt from the main, that is, from the working side, and not from the main / lower surface.
Roller supports of conveyor belt conveyors are the most optimal variant for adjusting the surface of the working surface relative to the axis of the conveying equipment. Roller supports are called centering and can be produced in several variants, the most common of which are rotating ones.
Simplicity and relevance
The conveying conveyor with rollers rotating around its axis, welded securely to the conveyor frame, is the simplest and most requested equipment. Such equipment is used in a variety of production areas.
Direct roller supports are another type of centering, and they are installed, as a rule, on conveyor belts for the transport of bulk goods. Due to these roller supports, the conveyor can be used to move large piece cargo at a low speed, or set to sort the goods or cargo in manual mode. Quite often, transporting tape equipment with this kind of roller bearings is used in construction, storage and mail.
Roller bearing conveyors can have a rubberized conveyor belt of various widths and lengths, for the convenience of which only the edges rest on the rollers. Due to such a design, in particular, quality cutting and correct molding of the bar from clay material is carried out.
It should be noted that this conveyor equipment, as a rule, moves the cargo at a low speed, that is, its relatively low productivity.
Number of rollers
In order to increase the productivity, the conveyor belt in this form of conveyor equipment is often made in the form of a trough and is used for more rapid execution of loading and unloading operations, moving on it, for example, the frozen materials. In the design of grooved conveyors, roller conveyors of belt conveyors whose price in Russia is very accessible, have from three or more rollers that support and give proper form to the elastic conveyor belt.
Double roller bearings are not used often, they are usually equipped with narrow conveyor belts, but if the width of the belt is more than one meter, the roller supports can have five independent rollers installed on one axis. It should be noted that the number of rollers on one support directly affects the cost of all conveyor equipment. Roller supports of conveyor belts can be bought from a reliable supplier or from the manufacturer.
Large-sized or large-sized materials are more conveniently transported by means of a so-called “garland”, it is an overhead roller bearing that is mounted on cable-rope conveyors. There are many advantages to this design, in particular, it is distinguished by its reduced pressure on the conveyor belt and increased service life of the bearings. In addition, the load on the “garland” can move at a very high speed.
