Abstract

The utility model relates to a super strong 428HC roller chain which is mainly used on motorcycles and is served as a 08BC roller chain on industrial transmission and agricultural machines. In the utility model, a pin shaft 1 is orderly connected with an outer chain plate 2, an inner chain plate 3 and a shaft sleeve 5 in series; the inner chain plate 3 and the outer chain plate 2 5 are sheathed and connected with rolling beads 4 on the shaft sleeve to form a single row chain; the middles of two or more than two single row chains are added with middle pieces 6 for connecting the single row chains to form double-row or multiple-row chains. The utility model is mainly characterized in that the diameter of the pin shaft is increaced, inner hole diameters 9 of the inner chain plate, the outer chain plate, middle pieces and the shaft sleeve are correspondingly enlarged, the diameters 10 of the excircles of both ends and the size 11 of the middle waist of the outer chain plate are enlarged, and the interval among the middle pieces and the pin shaft is reduced. The diameter of the pin shaft is from 4.50 mm to 4.80 mm, the diameter of the excircles of the outer chain plate is from 11.00 mm to 11.50 mm, the size of the middle waist of the outer chain plate is from 8.48 mm to 8.55 mm, and the interval among the middle pieces and the pin shaft is from 0.01 mm to 0.02 mm. Compared with original chains, the traction force of the utility model is enhanced by 20 percents, and the service life of the utility model is enhanced by 50 percents.

Description

Superpower 428HC roller chain

Affiliated technical field

The utility model is the superpower roller chain of using on the machinery such as agricultural vehicle, motorcycle and industrial transmission, belongs to chain-driven unit in the engineering goods.

Background technique

The 428H roller chain that uses on the motorcycle in the market, this chain is called the 08BH roller chain in agricultural machinery and industrial transmission, single strand chain and double strand chain are arranged, bearing pin is thinner, and its diameter is 4.45 millimeters, and outer plate is little, its outside diameter is 10.50 millimeters, and waist sizes is 8 millimeters in the middle of it.Matching gap between bearing pin and the middle sheet is big, and its gap is 0.05 millimeter.Because of bearing pin is thin, the anti-pulling force of chain is just poor.Outer plate is little also very easily to be damaged.Gap between bearing pin and the middle sheet is big, the big and easy kerve of on-stream wearing and tearing, and these have all greatly influenced the working life of chain.

Summary of the invention

The objective of the invention is the problem at above-mentioned existence, design the superpower 428HC roller chain that uses on a kind of novel motorcycle, this chain is called superpower 08BHC roller chain simultaneously in agricultural machinery and industrial transmission.This chain can improve pulling force, can reduce wear, and is difficult for kerve, can greatly improve the working life of chain.

The technical solution of the utility model is: be connected in series outer plate, inner plate, axle sleeve successively on bearing pin, inner plate, outer plate and socket ball composition single strand chain on axle sleeve.The sheet composition that is connected double or arrange chain more in adding in the middle of two or more single strand chains.The utility model does not change the basic structure of each component in the former chain and connecting means between them and mounting point, does not also change 8.5 millimeters of some basic parameter in the present both at home and abroad general part such as 12.7 millimeters of chain pitchs and ball outside diameters etc.Mainly take 1 technically, the diameter of overstriking bearing pin, and corresponding expansion is enclosed within the diameter of bore of outer plate, inner plate, middle sheet and axle sleeve on the bearing pin, can improve the anti-intensity of drawing of chain so significantly.2, enlarge the outside diameter and the middle waist sizes at outer plate two ends, thereby make the not fragile tensile strength that improves chain significantly of outer plate.3, dwindle in gap between sheet and the bearing pin, sheet and bearing pin is not easy to wear and kerve in making.In a word, such scheme can greatly improve the tensile strength of chain, increases pulling force and prolongs working life of chain.Concrete scheme is: the diameter of bearing pin from 4.45 millimeters overstrikings to the 4.50-4.80 millimeter.The diameter of bore of outer plate, inner plate, middle sheet and axle sleeve expands 4.48-4.75 millimeter, 6.20-6.35 millimeter, 4.58-4.85 millimeter and 4.68-4.85 millimeter respectively to from 4.34 millimeters, 6.33 millimeters, 4.48 millimeters and 4.55 millimeters.The outside diameter at outer plate two ends expands the 11.00-11.50 millimeter to from 10.50 millimeters, and the waist sizes in the middle of the outer plate expands the 8.48-8.55 millimeter to from 8 millimeters.Gap between middle sheet and the bearing pin narrows down to the 0.01-0.02 millimeter from 0.05 millimeter.

Because adopt such scheme, the utility model has improved pulling force than 428H roller chain, pulling force has improved 20%.In sheet, bearing pin not easy to wear, be difficult for kerve, bearing pin and outer plate are not fragile, have so just greatly improved the working life of chain, raising working life 50%.
