Abstract
The utility model relates to a metallic wire wound type elastic retainer ring for holes and shafts, belonging to universal fasteners of machine part category. The metallic wire wound type elastic retainer ring is characterized in that the metallic wire wound type elastic retainer ring is wound and shaped on a special winding device by a tailor-made elastic metallic wire with shaped cross section. The retainer ring is wedged in a retainer ring groove under the action of a wedge angle without excitation and loosing phenomena following the operation of a machine, and with more than 95% utilization ratio of materials and low cost, the utility model is likely to replace traditional elastic retainer rings formed by plates in a punching mode.
Description
This Let Meter belongs to the TMFC of machine components category.
The national standard circlip for hole GB893.1-86 in 1986 that continue to use at present, GB893.2-86 and circlip for shaft GB894.1-86, GB894.2-86 all is shaped through stamping-out with the 65Mn steel plate, stock utilization about 20%.Because the desired material thickness of back-up ring of different-diameter differs, with cover material way very big limitation is arranged, do not reach province's material purpose.
Secondly, the section of above-mentioned back-up ring is a rectangle, and back-up ring is packed into behind the circlip groove, has end play, and loosening tendency is arranged, and along with running up of machine, vibrates easily, causes fault.
The design with the elastic metallic yarn material enwinding type circlip of section, can reach and save steel and improve back-up ring performance two big purposes.
The section of elastic metallic yarn is the pentagon that is formed by the square-section, as shown in Figure 1.
The hole that turns to back-up ring as shown in Figure 2; Shaft block ring as shown in Figure 3.Among the figure: the 1-earhole is used to assemble purpose.2-crescent breach is used to adjust the rigidity of material different parts, makes back-up ring profile in assembling and dissembling process still keep circle.The 3-angle of wedge is positioned at the hole with the back-up ring outside, shaft block ring inboard, and the back-up ring wedging of packing into behind the circlip groove under angle of wedge effect is eliminated end play in circlip groove, and the vibration because of machine does not get loose.The 4-back-up ring.The 5-circlip groove.
The technical process of enwinding type back-up ring:
With the special special-shaped elastic metallic yarn in special-purpose way, coiling is shaped on the special-purpose coiling machine of the automation that designs voluntarily, develops, and finishes through heat treatment and surface treatment again.
Claims (3)
1, a kind of hole that is shaped with the coiling of dedicated elas-tic metal material is used and shaft-use elastic gear ring, it is characterized by: the pentagon of back-up ring transverse shape for being formed by rectangle.A side that is positioned at circlip groove has the angle of wedge.
2, according to the described circlip of claim 1, it is characterized by: the hole is the inboard and shaft block ring outside with back-up ring, and some crescent breach are arranged.
3, according to the described circlip of claim 1, it is characterized by: two earholes that are used to assemble purpose are that coiling is shaped.
