Description

Boring Ceramic Roller

technical field

The utility model relates to a boring ceramic idler.

Background technique

Nowadays, the ceramic idler replaces the traditional steel idler, which not only saves steel, but also has a small friction coefficient and strong corrosion resistance and wear resistance, thus increasing the service life of the idler and expanding the use Field, reduced production costs, has gradually been recognized by users.

A conventional idler (whether made of steel or ceramic) is composed of an idler body 1' (in the shape of a cone or a cylinder) and a through hole 2' in the center for the assembly shaft to be inserted (with bearing holes at both ends). , referring to Fig. 3 and Fig. 4, the through hole is consistent with the inserted assembly shaft and the fixed bearing position.

At this stage, my country's ceramic idler manufacturing industry is in the stage of research and development and growth. Although the market situation is getting better, due to the imperfection of production technology and process, the products still have many unsatisfactory features: for example, for conical ceramic idlers (See Figure 3, the main body of the idler roller is in the shape of a cone). Since the wall thickness of the large diameter end is greater than that of the small diameter, it is very difficult to sinter and form. The weight is relatively heavy, taking the conical ceramic roller of Φ108×Φ159×530 as an example, the weight after molding reaches 32KG. For ordinary national standard cylindrical ceramic rollers, there are also problems such as excessive wall thickness, difficulty in sintering and excessive weight after molding, resulting in excessive material consumption and increased production and transportation costs.

Contents of the invention

The purpose of the utility model is to provide a boring ceramic idler, which not only can meet the requirements of use, but also saves material, is light, and has a high yield.

In order to achieve the above object, the utility model takes the following design scheme:

A bored ceramic idler roller, comprising a ceramic roller body, the center of the ceramic roller body is provided with a through hole for the assembly shaft to be inserted, and at least one end of the through hole diameter for the assembly shaft is larger than the diameter of the assembly shaft and the bearing position .

The ceramic roller body can be conical and cylindrical, and the through hole for the assembly shaft to be inserted in the center is also a conical cylindrical hole. The aperture of the small diameter section coincides with the assembly shaft and the bearing position, and the aperture of the large diameter end is larger than the assembly shaft and the bearing. The diameter of the bit and is equipped with a bearing housing.

The ceramic roller body can also be cylindrical, and the through hole opened in the center for the insertion of the assembly shaft is also a cylindrical hole. The diameter of the entire section is larger than the diameter of the assembly shaft and the bearing position, and the two ends are equipped with bearing seats. .

The boring ceramic idler of the utility model is mainly an idler and a guide roller for belt conveyors, and can be widely used in belt conveyors in smelting, chemical industry, mining and other industries.

The utility model has the advantages of saving materials, reducing production and transportation costs, high molding rate, and easier processing and assembly.

Detailed ways

Referring to Fig. 1 and Fig. 2, the bored ceramic roller of the utility model includes a ceramic roller body 1, and the center of the ceramic roller body is provided with a through hole 2 for the assembly shaft to be inserted. At least one end of the inserted through hole is larger than the diameter of the assembly shaft and the bearing position.

As shown in Figure 1, the ceramic roller body 1 is conical and cylindrical, and the through hole 2 provided in the center for the insertion of the assembly shaft is also a conical cylindrical hole. The aperture of the small diameter section matches the assembly shaft and the bearing position, and the large diameter The diameter of the end hole is larger than the diameter of the assembly shaft and the bearing position, and the bearing seat 3 is equipped with it. The taper of the through hole 2 opened in the center for the installation of the assembly shaft is consistent with the taper of the ceramic roller body 1, which ensures that the wall thickness of the ceramic roller body is uniform and the overall weight is reduced. Take shaped ceramic carrier roller as an example, the weight after the utility model is designed to be molded is only 18KG.

As shown in Figure 2, the ceramic roller body 1 is cylindrical, and the through hole 2 provided in the center for the insertion of the assembly shaft is also a cylindrical hole. The diameter of the entire section is larger than the diameter of the assembly shaft and the bearing. All equipped with bearing housing 3.

The boring ceramic idler roller of the utility model has simple structure and low manufacturing cost, and the existing extrusion equipment can be used to increase the inner hole by adopting the inner hole boring technology, and finally fired. The wall thickness of the advanced ceramic roller is greatly reduced, which makes the drying of the molding faster, the wall of the ceramic roller is heated more uniformly, the material properties of the product are more balanced and stable, and the performance of the overall product is enhanced. And when assembling, it is easier and easier to insert the assembly shaft.
