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.
[0008] The 08B double-row roller chains produced and used at home and abroad all have the disadvantages of thin pin shafts and small chain pieces, so the tensile strength is small, the wear resistance is poor, and the service life is short.

Embodiment Construction

[0029] As shown in each figure: a 08BHC double row roller chain. It comprises pin shaft 1, outer chain plate 2, inner chain plate 3, middle chain plate 4, roller 5, sleeve 6.

[0030] The diameter of the pin shaft 7 is enlarged from the original 4.45 mm to 4.63 mm.

[0031] The diameter 8 of the inner hole of the outer chain sheet is enlarged to 4.48 millimeters from the original 4.38 millimeters. The diameter 9 of the waist of the outer chain piece is enlarged from the original 8 mm to 8.5 mm. The diameter 10 of the outer circle of the outer chain sheet is enlarged from the original 10.5 millimeters to 11 millimeters. Outer chain piece thickness 11 expands to 2 millimeters from original 1.6 millimeters.

[0032] The thickness 12 of the inner chain sheet is expanded from the original 1.6 millimeters to 2 millimeters.

[0033] The inner hole diameter 13 of the middle chain sheet is enlarged from the original 4.48 mm to 4.65 mm. The waist diameter 14 of the middle chain pie...

Abstract

The invention discloses a 08 BHC double-row roller chain. The diameter of a pin shaft is 4.48-4.70 millimeters. The bore diameter of an outer chain sheet is greater than 4.38-4.63 millimeters. The diameter of the waist part for the outer chain sheet is 8.5-11 millimeters. The diameter of the excircle of the outer chain sheet is 11-12 millimeters. The thickness of the outer chain sheet is 1.8-2.03 millimeters. The thickness of an inner chain sheet is 1.8-2.03 millimeters. The bore diameter of a middle chain sheet is greater than 4.48-4.68 millimeters. The diameter of the waist part for the middle chain sheet is greater than 10-12 millimeters. The diameter of the excircle of the middle chain sheet is 11 millimeters. The thickness of the middle chain sheet is 2.4 millimeters. Compared with the original 08 B double-row roller chain, the pulling force of the 08 BHC double-row roller chain is increased from 3,110KG to 3,600KG. Wear-resisting property of chain is improved greatly. The service life of the chain is also prolonged by 30%.

Description

technical field [0001] The invention relates to a roller chain, in particular to a 08BHC double-row roller chain, which 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, and 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. The disadvantages are: a...
