Embodiment 1

[0013] A fine-grained alumina ceramic belt idler cylinder body, which includes a steel pipe 1, a fine-grained alumina ceramic pipe 3 is fixed outside the steel pipe 1, the steel pipe 1 and the ceramic pipe 3 are coaxially installed, and the steel pipe 1 and the ceramic pipe 3 The gap between them is 1-1.6 mm, and the viscose fixing layer 2 is in the gap. The thickness of the ceramic tube 3 is 5-8 mm, and the outer diameter of the ceramic tube 3 is 80-130 mm, which can be adjusted according to user needs. The thickness of the steel pipe 1 is 2-3 mm.

Embodiment 2

[0015] A fine-grained alumina ceramic belt idler cylinder body, which includes a steel pipe 1, a fine-grained alumina ceramic pipe 3 is fixed outside the steel pipe 1, the steel pipe 1 and the ceramic pipe 3 are coaxially installed, and the steel pipe 1 and the ceramic pipe 3 The gap between them is 1.5 mm, and the adhesive fixed layer 2 is in the gap, that is, the thickness of the adhesive layer is 1.5 mm. The thickness of the ceramic tube 3 is 6mm, and the outer diameter of the ceramic tube 3 can be 89mm, 110mm, 120mm, which can be adjusted according to user needs. The thickness of the steel pipe 1 is 2-3mm, and the gap between the steel pipe 1 and the ceramic pipe 3 is 1.5mm.

Embodiment 3

[0017] A processing method for the fine-grained alumina ceramic belt idler cylinder is as follows: firstly, the outer surface of the steel pipe 1 is coated with special glue, and then the ceramic pipe 3 is set on the steel pipe 1, and the steel pipe 1 and the ceramic pipe 3 are adjusted so that the steel pipe 1 and the ceramic pipe 3 are basically Coaxial and fixed, and then cured naturally. Among them, special viscose can be purchased directly in the market.

Abstract

The invention relates to a fine alumina ceramic belt supporting roller cylinder and a processing method thereof. The fine alumina ceramic belt supporting roller cylinder comprises a steel tube which is externally and fixedly sheathed with a fine alumina ceramic tube, the steel tube and the ceramic tube are installed coaxially and the clearance between the steel tube and the ceramic tube is 1 to 1.6mm and is filled with an adhesive fixing layer. The thickness of the ceramic tube is 5 to 8mm, and the clearance between the steel tube and the ceramic tube is 1.5mm, namely, the thickness of the adhesive layer is 1.5mm. The processing method of the cylinder comprises the steps that firstly the outer surface of the steel tube is coated with a special adhesive and then the ceramic tube is sheathed on the steel tube, and the steel tube and the ceramic tube are adjusted to be basically coaxial and finally cured naturally. The technical proposal of the fine alumina ceramic belt supporting roller cylinder with high wear resistance, good vibration resistance, high bending strength and long service life adopts the perfect combination of the steel tube and the ceramic tube, thus effectively overcoming the defects and the deficiency of the existing single steel tube and ceramic tube and having simple processing method and easy execution and operation.

Description

technical field [0001] The invention relates to a belt idler cylinder and a processing method thereof, in particular to a fine-crystalline alumina ceramic belt idler cylinder and a processing method thereof. Background technique [0002] The existing belt idlers generally use steel cylinders, which have poor wear resistance. In order to solve this problem, people think of replacing steel cylinders with ceramic cylinders. However, due to the relatively high brittleness of ceramics, ceramic cylinders are used. The wear resistance of the roller is improved, but because its working environment is mostly mines, docks and industrial and mining enterprises, it is also required to be anti-vibration and anti-bending. In the prior art, the ceramic cylinder is used, and its length is restricted, and the length cannot be processed to be more than 1 meter, and the prior art cannot solve this problem. Contents of the invention [0003] The present invention aims at the deficiencies in ...
