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
The present invention is a kind of roller chain, and particularly a kind of 08BHC duplex chain bar belongs to the chain-driven technical field in the engineering goods.
Background technique
Chain-driven unit on the machinery such as tractor, motorcycle and industrial transmission is the series of standards product at present, and international, domestic widely used standardized product is mainly " A " and " B " series product.Product specification is mainly 08A-48A roller chain and 05B-48B roller chain.The roller chain that country such as the U.S. produces is with " A " serial using names, and its deficiency is: chain sheet waist is little, and bearing pin is thin, thereby wear-resisting property is poor, and stretching resistance is little, and working life is short.The roller chain that country such as Britain, Germany produces is with " B " serial using names, and its deficiency is: though bearing pin is thick, the chain sheet is thin, and profile is little, thereby stretching resistance is poor.China produces always and uses " A ", " B " series standard model roller chain of countries such as the U.S., Britain, Germany.There are shortcomings such as tensile strength is little, wear-resisting property is poor, and working life is short generally in above-mentioned roller chain.In view of the foregoing, the inventor designs a kind of novel 08BHC duplex chain bar through for many years production experiment and scientific research and innovation on the basis of former 08B duplex chain bar.
The situation of each parts of 08B duplex chain bar is as follows:
The diameter of bearing pin is 4.45 millimeters.
The outer chain sheet diameter of bore is 4.38 millimeters.The outer chain sheet waist diameter is 8 millimeters.The outer chain sheet outside diameter is 10.5 millimeters.Outer chain sheet thickness is 1.6 millimeters.
Inner chain sheet thickness is 1.6 millimeters.
Medium chain sheet diameter of bore is 4.48 millimeters.Medium chain sheet waist diameter is 10 millimeters.Medium chain sheet outside diameter is 10 millimeters.Medium chain sheet thickness is 1.6 millimeters.
The 08B duplex chain bar that produce to use the home and abroad exists all that bearing pin is thin, the chain sheet is little, thereby tensile strength is little, wear-resisting property is poor, the shortcoming that working life is short.
Summary of the invention
The objective of the invention is to design that a kind of tensile strength is big, wear-resisting property good, the 08BHC duplex chain bar of long service life.
Technological scheme of the present invention is: a kind of 08BHC duplex chain bar.It comprises bearing pin, outer chain sheet, inner chain sheet, medium chain sheet, roller, sleeve.Be characterized in:
The diameter of bearing pin expands the 4.48-4.70 millimeter to from original 4.45 millimeters.
The outer chain sheet diameter of bore expands to＞the 4.38-4.63 millimeter from original 4.38 millimeters.The outer chain sheet waist diameter expands the 8.5-11 millimeter to from original 8 millimeters.The outer chain sheet outside diameter expands the 11-12 millimeter to from original 10.5 millimeters.Outer chain sheet thickness expands the 1.8-2.03 millimeter to from original 1.6 millimeters.
Inner chain sheet thickness expands the 1.8-2.03 millimeter to from original 1.6 millimeters.
Medium chain sheet diameter of bore expands to＞the 4.48-4.68 millimeter from original 4.48 millimeters.Medium chain sheet waist diameter expands to＞the 10-12 millimeter from original 10 millimeters.Medium chain sheet outside diameter expands 11 millimeters to from original 10 millimeters.Medium chain sheet thickness expands 2.4 millimeters to from original 1.6 millimeters.
This 08BHC duplex chain bar does not change basic structure and the connecting means between them and the mounting point of each component in the former 08B duplex chain bar, does not also change the pitch in the 08B duplex chain bar, the internal segment inner width.So just make this 08BHC duplex chain bar can in all 08B duplex chain bar using scope, use and change old 08B duplex chain bar.
Advantage of the present invention is: this 08BHC duplex chain bar is compared with former 08B duplex chain bar.Pulling force is brought up to 3600KG from 3110KG.And greatly improved the wear-resisting property of chain.Also improved 30% the working life of chain.
