Embodiment Construction

[0030]Figure 1 shows a guide designed according to a design of the present invention. The guide comprises an adjusting ring 6 , which is mounted rotatably about the turbine axis A in the turbine housing 1 . By turning the adjustment ring 6 around the turbine axis A, the guide vanes 2 supported in the guide vane holder 3 can pivot, thereby adjusting the exhaust gas flow to match the exhaust gas turbine (not shown in the figure) . The guide vane 2 is connected to the adjusting ring 6 through an adjusting rod in a manner not shown in detail in the figure.

[0031] In order to rotate the adjusting ring 6 around the turbine axis A, two adjusting devices are provided symmetrically distributed on the circumference of the adjusting ring 6 . Each adjustment device includes a screw rod 7 that is connected to and driven by a universal joint shaft 100 (accompanying drawing 3 ) and an actuating motor (not shown in the figure) for anti-rotation.

[0032] The screw 7 is mounted rotatably ...

Abstract

A guiding device for waste gas turbocharger of piston-type internal combustion engine with heavy oil as fuel using for guiding for axial air intaking turbine, the device comprises a plurality of tunableness guide vanes (2) supporting in the turbine shell (1), an adjusting ring (6) for adjusting the guide vanes (2), and a adjusting device which makes the adjusting ring (6) to rotate oppositely to the turbine shell (1), the adjusting device directly supports the adjusting ring with a first supporting part and a second supporting part directly supports the turbine shell for adjusting the rotation of the adjusting ring to the turbine shell. The adjusting device has a cooling device (13, 110).

Description

technical field [0001] The invention relates to a guide according to the preamble of claim 1 and to a method for adjusting the guide vanes of the guide. Background technique [0002] DE 100 13 335 A1 discloses a guide for an axial exhaust gas turbine of a turbocharger, in which several guide vanes are mounted in an adjustable manner in the turbine housing. The individual guide vanes are connected via adjusting rods to an adjusting ring mounted rotatably around the turbine shaft. The exhaust gas flow is adjusted by turning the adjustment ring to make the guide vane swing in the turbine housing. [0003] A force-transmitting rod is fixed to the adjusting ring, and an external control device, not specified in detail, acts on the rod from the end of the rod facing away from the adjusting ring. In order for the adjusting ring to turn, the first support of the external control must be supported on this rod and the second support must be supported in a fixed manner. [0004] Sin...
