Description

Butt joint shaft structure and belt conveying line

Technical Field

The utility model belongs to the technical field of rigid connecting shafts, and particularly relates to a butt joint shaft structure and a belt conveying line.

Background

In the production line, it is usual to use belt conveyors for transporting the material, since some materials are large in transverse span, there is a length dependence on the supporting shafts on the belt conveyors for supporting the belt.

If the shaft body is too long and the diameter of the shaft body is small, even if a solid shaft body is used, a certain sagging of the middle position of the shaft body occurs due to lack of corresponding support. Meanwhile, the structural processing technology of the shaft body is improved in manufacturing complexity due to the fact that the shaft body is lengthened, and corresponding processing production cost is high.

Considering the connection of shaft segments, chinese patent No. CN204729487U discloses a shaft-to-shaft butt joint structure, which discloses a structure for butt joint of adjacent shaft bodies. The novel clutch comprises a driving shaft, a driven shaft and a coupling, wherein one end of the coupling is connected with the molded surface of the driving shaft, and the other end of the coupling is connected with the molded surface of the driven shaft. Compared with the traditional key connection, the shaft-shaft butt joint structure provided by the utility model has the advantages of high connection strength, no stress concentration, high efficiency and impact load bearing, and is convenient to disassemble and repair for some large-scale mechanical equipment.

Therefore, two adjacent sections of shaft bodies are connected through the coupler, and the butt joint structure protrudes out of the outer surface of the shaft bodies, so that the belt conveyor line is worn.
