Definitions
- the invention relates to a method for producing a piston ring.
- Piston rings are often made of cast iron, cast steel or steel wire. Currently, u.a. Piston rings with so-called self-sharpening scraping edges in the form of chambered rings with chrome layers used.
- DE 10 2007 007 961 A1 discloses a piston ring having a base body which has a substantially circumferential tread, an upper and a lower flank surface and an inner peripheral surface, wherein the transition region of the tread at least into the lower flank surface with an edge ⁇ 0, 1 mm provided and the tread is at least provided with a PVD cover layer ⁇ 10 mm.
- the piston ring includes a tread provided with a tread and an upper and a lower flank surface, wherein at least the tread is provided with a vapor deposition layer, such that a portion of the tread is provided with a removable cover, so that after generation of the vapor deposition layer and Removal of the cover a substantially
- the invention has for its object to provide an alternative method for producing provided with a PVD layer piston rings, wherein the piston ring over the prior art has an improved wiping effect.
- This object is achieved by a method for producing a piston ring, by a metallic base body, at least including a radially outer
- Running surface, a radially inner peripheral surface and extending therebetween upper and lower flank surfaces in the region of an approximately cylindrically shaped tread is provided with a defined conicity, at least the tread is provided with at least one wear-resistant layer and that, forming a scraping edge region of the at least one wear layer, substantially cylindrical, forming a web of predetermined width, at least partially removed.
- Wiper edge proposed, which is prepared by the method according to the invention.
- an improvement of the wiping action of the piston ring, in particular of the compression piston ring can be achieved such that a self-sharpening wiping edge (functional edge) is formed, which is not outbreak risk.
- the conicity of the annular raceway is advantageously introduced mechanically into the tread.
- the bar width exposed after cylindrical machining is, according to another idea of the invention, between 0.05 and 0.45 mm.
- the suitably produced tread conicits, for example between 30 and 120 minutes, are introduced into the tread to be produced before the coating, the procedure being independent of the ring material.
- the wiper edge of cast iron piston rings can be rounded sharp-edged (90 °) or, depending on requirements, up to a radius of 0.1 mm.
- the area of the scraping edge can be nitrided or unnitrated.
- the scraping edge can be made sharp-edged (90 °).
- the scraping edge includes a radial feed ⁇ 0.1 mm
- the steel bar and the running surface are nitrided, with no nitriding layer below the PVD top layer.
- the wiper edge is provided with a chamfer ⁇ 0.15 mm, the steel web and the running surface are nitrided, in which case a nitriding layer remains underneath the PVD cover layer.
- piston rings in particular compression piston rings, can thus be produced which are provided with at least one wear-resistant layer, preferably a PVD layer.
- the PVD layer is already to be regarded as a cover layer, the same is approximately cylindrically removed in the area of the wiper edge except for the base material, so that a web of predefinable width is produced. If several wear layers are present, then the PVD cover layer can be ground down to the base material of the tread, or only so far that at least one wear-resistant layer (for example a nitriding layer) remains below the PVD cover layer.
- a web is formed with a defined width in the region of the sharp-edged, rounded or provided with a bevel edge.
- Figure 1 pictorial representation for the preparation of a piston ring
- FIG. 2 shows different embodiments of one, after
- Figure 3 representation of an at least partially nitrided and provided with a PVD cover layer piston ring.
- Figure 1 contains three pictures.
- the upper picture shows an enlarged view of a piston ring main body 1, which, as indicated, initially had a rectangular shape.
- This cross-sectional profile reveals the following piston ring areas: a lower one
- Tread taper 5 ' (for example, 100 minutes) mechanically introduced.
- the main body 1 can be seen, but this time provided with a PVD cover layer 7, which, according to the predetermined tread pattern 5 ', is deposited on the tread 5.
- the lower image of Figure 1 shows that to produce a web 8 with a predetermined width h ', the PVD cover layer 7 except for the base material of
- Tread 5 is sanded. This type of processing will be the
- sharp-edged scraper edge 6 is formed, which, by the defined distance h 'to the PVD cover layer 7, is not prone to breakout and sharpens itself in the operating state.
- FIG. 1 shows that the PVD layer 7 as the sole wear-resistant layer simultaneously forms the cover layer.
- FIG. 2 likewise shows three images, wherein the upper image represents the finished piston ring according to the lower image of FIG.
- the width of the web 8 is given here with 0.05 to 0.45 mm.
- the middle picture shows a piston ring 1 'with a maximum radius of 0.1 mm in the region of the wiping edge 6.
- a chamfer / chamfer is recognizable, which enters at an angle in the lower flank surface 2.
- the web width is reduced by a maximum of 0.15 mm.
- the wiping edge 6 can be made nitrided or unnitrated, whereby the wiping edge 6 is advantageously made sharp-edged (90 °) in a non-nitrided embodiment, as shown in the upper picture of FIG.
- FIG. 3 likewise contains three images which correspond in contour to those of FIG. Different from FIG. 2, the web 8 and the running surface 5 are nitrided before the PVD covering layer 7 is applied. In this case, the
