12ACC double-row roller chain with thick outer chain sheet

Abstract

The invention provides a 12ACC double-row roller chain with a thick outer chain sheet. The roller chain comprises a pin shaft, an outer chain link, an inner chain link, a middle chain sheet, a roller and a barrel and is characterized in that: the thickness of an outer chain sheet of the inner chain link is increased from 2.4 centimeters to 3.0 centimeters; and the thickness of an outer chain sheet of the outer chain link is increased from 2.4 centimeters to 3.0 centimeters. The invention has the advantage that: the 12ACC double-row roller chain with the thick outer chain sheet, which has high tensile strength and long service life, is designed. The tension of the double-row roller chain is increased from 6,200 KG of the conventional 12A double-row roller chain to 8,200 KG. Moreover, the service life of the chain is prolonged by 30 percent.

Description

technical field [0001] The invention relates to a roller chain, in particular to a 12ACC double-row roller chain with thick outer chain pieces, and belongs to the technical field of chain transmission in mechanical products. Background technique [0002] At present, the chain transmission devices on mechanical equipment such as tractors, motorcycles and industrial transmissions are a series of standard products. The standard products widely used internationally and domestically are mainly "A" and "B" series products. The product specifications are mainly 08A-48A roller chain and 05B-48B roller chain. The roller chains produced in the United States and other countries are named after the "A" series. The disadvantages are: the chain piece has a small waist and a thin pin shaft, so the wear resistance is poor, the tensile force is small, and the service life is short. The roller chains produced in the United Kingdom, Germany and other countries are named after the "B" series....

AI Technical Summary

Problems solved by technology

The roller chains produced in the United States and other countries are named after the "A" series. The disadvantages are: the chain piece has a small waist and a thin pin shaft, so the wear resistance is poor, the tensile force is small, and the service life is short.

The roller chains produced in Britain, Germany and other countries are named after the "B" series. The disadvantages are: although the pin shaft is thick, the chain pieces are thin and the shape is small, so the tensile strength is poor.

The double-row roller chain is easy to break due to the thin chain, so the tensile strength is small and the service life is short
