Axle chain

Abstract

The invention discloses an axis chain. The axis chain comprises a chain plate with an inner connection end hole and an outer connection end hole, a square-circular boss-type sleeve installed in the inner connection end hole of the chain plate, a mandrel inserted in the outer connection end hole of one section of the chain plate and the square-circular boss-type sleeve at the inner connection end of another section of the chain plate, a clamping plate next to the outer connection end of the chain plate and inserted in the groove of the mandrel, a screw for fastening the clamping plate on the outer connection end of the chain plate, and a conveyer installed at the middle of the mandrel, wherein an oblate hole is formed in the inner connection end of the chain plate, and a circular hole is formed in the outer connection end. The axis chain disclosed by the invention is simple in structure, good in location, uniform in stress, high in interchangeability, easy to realize batch production, convenient to detach, good in running, wear-free and long in service life.

Description

technical field [0001] The invention relates to an axis chain, which can be widely used in the conveying chain of material conveying machinery, especially in the conveying chain of low-speed and heavy-duty material conveying machinery. Background technique [0002] In the existing chain conveying device, the connection between the chain and the conveying body is realized on the chain plate or the chain ring, and a separate connecting piece needs to be added, and the structure tends to be complicated. Or direct welding connection, it is inconvenient to disassemble, and it will also cause uneven stress on the double chain plate chain, deformation and wear. The limit of the mandrel is only to limit its axial movement. In the heavy-duty transmission, the relative rotation between the mandrel and the chain plate is easy to occur, and the holes and pins of the chain plate are worn, which leads to the change of the chain pitch and the meshing of the chain sprocket. The transmissio...

[0002] In the existing chain conveying device, the connection between the chain and the conveying body is realized on the chain plate or chain ring, and a separate connecting piece needs to be added, and the structure tends to be complicated

Or direct welding connection, it is inconvenient to disassemble, and it will also cause uneven force on the double chain plate chain, deformation and wear

The limit of the mandrel is only to limit its axial movement. In the heavy-duty transmission, the relative rotation between the mandrel and the chain plate is easy to occur, and the holes and pins of the chain plate are worn, which leads to the change of the chain pitch and the meshing of the chain sprocket. Unstable transmission, increased internal interference and wear of equipment, resulting in stuffy cars and jams, causing equipment failure
