Abstract
The invention belongs to mechanical design fields, especially a kind of chain seamless heterotype sleeve, the lateral wall of special-shaped sleeve is straight arm type, it is symmetrical centre into upper and lower mirror-symmetrical two flare openings that its inner sidewall, which is constituted using the central horizontal cross section of special-shaped sleeve, two flare openings are opposite, and the smooth-sided of the joint of two flare openings is excessive.After special-shaped sleeve of the invention is used for chain, but chain is attached to when working on turning machine and contacts between abnormal shape sleeve and pin shaft for link friction, frictional force is reduced compared with the mode for putting friction between prior art middle sleeve and pin shaft, reduce abrasion loss, improve service life of the chain on turning machine equipment, the elongation of chain initial stage is substantially improved, device requirement is met.
Description
Technical field
The invention belongs to mechanical design field, especially a kind of chain seamless heterotype sleeve.
Background technique
Chain barrel in the prior art uses ordinary carbon steel, is rolled with coiling sleeve equipment, and end face is irregular,
It is difficult to ensure concentricity and circularity；Common chain structure includes outer plate, inner sheet, ordinary cartridge, pin shaft and roller, outer plate and pin
Axis interference fit, inner sheet and ordinary cartridge are interference fitted, and pin shaft and ordinary cartridge are clearance fit, and ordinary cartridge outboard sidewalls are all
It is for straight arm type structure, i.e., identical with the outboard sidewalls of cylinder, straight slope-less.
The chain being attached on turning machine between ordinary cartridge sleeve and pin shaft is point contact when work, as shown in figure 4, together
Etc. weight, point contact frictional force is big, accelerate abrasion.
Furthermore chain elongation is not comparatively fast able to satisfy device requirement, considerably increases cost.
Summary of the invention
According to the above-mentioned deficiencies of the prior art, the present invention provides a kind of chain seamless heterotype sleeve, chain can be improved
Service life, improve chain initial stage elongation.
Present invention solves the technical problem that the technical solution used are as follows: a kind of chain seamless heterotype sleeve, special-shaped sleeve
Lateral wall is straight arm type, and inner sidewall constitutes symmetrical at upper and lower mirror surface by symmetrical centre of the central horizontal cross section of special-shaped sleeve
Two flare openings, two flare openings are opposite, the smooth-sided of the joint of two flare openings
Excessively.
Further, the flare openings of top be the upper end opening formed after being rotated a circle with parabolic path,
The small structure of big lower ending opening.
Further, the inner sidewall of the junction of the flare openings of the flare openings and lower section of top is equal
It is perpendicular with the central horizontal cross section of special-shaped sleeve.
Further, the special-shaped sleeve is the production of low-carbon alloy steel material.
The invention has the following advantages: special-shaped sleeve of the invention is packed into chain, chain is attached to turning machine work
When abnormal shape sleeve and pin shaft between contacted for link friction, subtract compared with the mode for putting friction between prior art middle sleeve and pin shaft
Small frictional force reduces abrasion loss, improves service life of the chain on turning machine equipment；Simultaneously as avoiding existing skill
Point abrasion bring chain in art between ordinary cartridge oral area and pin shaft elongates, so the elongation of chain initial stage is substantially improved,
Meet device requirement.

Specific embodiment
The present invention is described further with reference to the accompanying drawing.
Embodiment one:
As shown in fig. 1~fig. 5, a kind of chain seamless heterotype sleeve of the present invention, the lateral wall of special-shaped sleeve 3 is straight
Arm-type, i.e., lateral wall is identical as a common cylindrical lateral wall, and inner sidewall is constituted with the central horizontal of special-shaped sleeve 3
Cross section is symmetrical centre into upper and lower mirror-symmetrical two flare openings 31, and two flare openings 31 are opposite, two
The smooth-sided of the joint of a flare openings 31 is excessive.
Further, the flare openings 31 of top are that the upper end formed after being rotated a circle with parabolic path is opened
The small structure of mouth, big lower ending opening.
Further, the inside of the junction of the flare openings 31 of the flare openings 31 and lower section of top
Wall is perpendicular with the central horizontal cross section of special-shaped sleeve 3.
Further, the special-shaped sleeve 3 is the production of low-carbon alloy steel material.
If FIG. 1 to FIG. 2 is the chain for having used special-shaped sleeve 3, including outer plate 1, inner sheet 2, special-shaped sleeve 3, pin shaft 4 and rolling
Son 5, outer plate 1 and pin shaft 4 are interference fitted, and inner sheet 2 and special-shaped sleeve 3 are interference fitted, and pin shaft 4 and special-shaped sleeve 3 are clearance fit,
Chain is using on turning machine, contacts between special-shaped sleeve 3 and pin shaft 4 for link friction, reduces frictional force, improve chain
Service life on turning machine equipment.By this special-shaped sleeve 3, so that by original point between special-shaped sleeve 3 and pin shaft 4
Contact upgrades to line contact, reduces frictional force, reduces abrasion loss, and the service life of chain by improving to 2 years for 6 months, the longevity
Life improves 300%.
As shown in figure 4, the chain semi-finished product in the prior art equipped with ordinary cartridge 30, the top of ordinary cartridge 30 and pin
Abrasion between axis 4 is point contact abrasion, and since contact area is small, initial wear is serious, and chain elongation is obvious；
As shown in figure 5, be equipped with the chain semi-finished product of special-shaped sleeve 3, between the top and pin shaft 4 of special-shaped sleeve 3 because
Initial wear position in oral area, is not displaced downwardly to position among sleeve, is line contact wear, since contact area increases,
Initial wear amount reduces, and chain elongation substantially reduces, and meets device requirement.
The above is the embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize the present invention
Equivalent structure or equivalent flow shift made by specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
