Abstract
The invention discloses a kind of roller chain sleeve rolling process, sleeve rolls processing using flat filament material, flat filament material rectangular cross-section and trapezoidal compound cross-section, the stage casing rectangular in cross-section of flat filament material, the left and right ends section of flat filament material is trapezoidal, the long bottom edge of trapezoid cross section is docked with length of sides such as the broadsides of rectangular section, and the internal diameter at the sleeve both ends through edge rolling forming is more than the internal diameter in stage casing.It is more than the internal diameter in stage casing using the internal diameter at the sleeve both ends of technique edge rolling forming, since sleeve outer diameter and inner plate hole are interference fit, after press fitting, so that sleeve both ends internal diameter is consistent with stage casing internal diameter, it is bad to eliminate the diameter contracting after former process sleeve press fitting, and then the wear-resisting property of chain is improved, it is whole partially short and meet design requirement to avoid chain length.
Description
Technical field
The present invention relates to roller chain technical fields, more particularly, to a kind of roller chain sleeve rolling process.
Background technology
Roller chain is used in assembling process middle sleeve outer diameter and inner plate hole and is interference fitted, as shown in figs. 1 and 2, due to
The extruding force of interference fit makes hub internal bore surface generate " diameter contracting ".Diameter contracting causes contact of the sleeve lining with axis pin to be that point connects
It touches, by quickly worn out, the metal fragment for wearing generation is further exacerbated by rubbing for axis pin and sleeve for the infiltration layer of point contact position axis pin
It wipes, integrally reduces the wear-resisting property of chain.Meanwhile diameter contracting reduces the fit clearance of axis pin and sleeve, causes chain length whole
It is partially short.
Invention content
In view of the deficiencies of the prior art, the technical problem to be solved is that provide a kind of roller chain coiling sleeve work by the present invention
Skill can be contracted using the sleeve of the technique productions in assembling process to avoid diameter is generated.
The present invention is so that above-mentioned technical problem is addressed by the following technical programs.
A kind of roller chain sleeve rolling process, sleeve roll processing using flat filament material, flat filament material rectangular cross-section with it is trapezoidal
Compound cross-section, the left and right ends section of the stage casing rectangular in cross-section of flat filament material, flat filament material is trapezoidal, the long bottom edge of trapezoid cross section
It is docked with length of sides such as the broadsides of rectangular section, the internal diameter at the sleeve both ends through edge rolling forming is more than the internal diameter in stage casing.
Preferably, trapezoid cross section is in a rectangular trapezoid.
To sum up, roller chain sleeve rolling process using the present invention, the internal diameter at the sleeve both ends of edge rolling forming is more than
The internal diameter in stage casing, since sleeve outer diameter and inner plate hole are interference fit, after press fitting so that in sleeve both ends internal diameter and stage casing
Diameter is consistent, bad to eliminate the diameter contracting after former process sleeve press fitting, and then improves the wear-resisting property of chain, avoids chain
Long entirety is partially short and meets design requirement.

Specific implementation mode
In order to facilitate understand the present invention, below in conjunction with the accompanying drawings in provide the present invention preferred embodiment to the present invention into
The detailed description of row.
A kind of roller chain sleeve rolling process of the present invention, sleeve roll processing using flat filament material, specifically roll technology
Conventional technique can be used in means, and this will not be repeated here.As shown in Figures 3 to 5, the flat filament material rectangular cross-section of use with it is trapezoidal
Compound cross-section, the left and right ends section of the stage casing rectangular in cross-section of flat filament material, flat filament material is trapezoidal, the long bottom of trapezoid cross section 2
Side is docked with length of sides such as the broadsides of rectangular section 1, and as shown in Figure 6 and Figure 7, the internal diameter at the sleeve both ends through edge rolling forming is more than
The internal diameter of section.Referring to Fig. 8 to Figure 11, the front and back schematic diagram of comparison press fitting is it is found that due to the new process system using this flat filament material
At sleeve diameter slightly larger than intermediate internal diameter, sleeve outer diameter and inner plate hole are using being interference fitted, the sleeve both ends after press fitting
Internal diameter is consistent with intermediate internal diameter, to eliminate after former process sleeve press fitting there is diameter contracting caused by chain length it is partially short and point connects
The problem of touching.
In a specific embodiment, referring to Fig. 3 to Fig. 5, take the length L1 of flat filament material, width L2 be respectively 8cm and
7.88cm, trapezoid cross section 2 use right-angled trapezium, and the broadside of rectangular section 1 is with the long bottom edge a equal lengths of trapezoid cross section 2 to being connected in
The difference a-c of 0.51cm, the long bottom edge a and short bottom edge c of trapezoid cross section 2 are 0.05cm, and the height h of trapezoid cross section 2 is 1.5cm.
Referring to Fig. 6 it is found that using the flat filament material edge rolling forming a sleeve embodiment in, the stage casing outer diameter Φ of sleeve
A is 4.15cm, and the stage casing internal diameter Φ B of sleeve are 3.12cm, and the internal diameter Φ C of the two-port of sleeve are 3.22cm, the both ends of sleeve
The internal diameter Φ C of mouth are slightly larger than the stage casing internal diameter Φ B of sleeve so that after press fitting, in the internal diameter Φ C and sleeve of the two-port of sleeve
Section internal diameter Φ B are consistent, to eliminate the diameter contracting phenomenon after former process sleeve press fitting.
Several technical terms used in the present invention are intended merely to facilitate description, are not construed as limiting the invention,
The present invention is not limited to above-described preferable embodiment, the public affairs that can be known based on those skilled in the art
Know technology or use and is capable of the various modifications of equivalence replacement and the embodiment of change in the prior art, it is every to be based on this hair
Bright spirit or technical concept, should all be included in the protection scope of the present invention.
