摘要:
An exhaust-gas turbocharger with a bearing housing which receives a static bearing bush for a rotor shaft. A lug supported in the bearing housing engages the bearing bush and prevents the bearing bush from rotating but avoids a restriction of the freedom of movement of the bearing bush in the axial and radial directions.
摘要:
An exhaust-gas turbocharger (1) having a compressor (2) which has a compressor wheel (3) in a compressor housing (4); a turbine (5) which has a turbine wheel (6) in a turbine housing (7); a bearing housing (8) which receives a static bearing bush (9) for a rotor shaft (10) and which has, at the compressor side, a bearing housing cover (11), and a bearing bush rotation prevention means (12) which has at least one lug (13, 14, 15) supported in the bearing housing (8) and which engages into at least one of two grooves (16, 17) of the bearing bush (9). The grooves (16, 17) are arranged diametrically oppositely on an outer circumferential region (18) of the bearing bush (9).

An exhaust-gas turbocharger (1), having a shaft (2) on which a compressor wheel (3) and a turbine wheel (4) are arranged, and a bearing housing (5) which has a turbine-side radial bearing bush (6) and which has an oil collecting chamber (7) arranged between the turbine-side radial bearing bush (6) and a turbine-side bearing housing end region (8). The shaft (2) has a shoulder (9) which extends outward in the radial direction (R) into the oil collecting chamber (7) and, together with a radial-bearing-side first delimiting wall (10) of the oil collecting chamber (7), delimits a gap (11).

摘要:
A method for producing a rotationally symmetrical hollow metal part, particularly a shaft. According to the method, bar-shaped ductile solid matrial is provided, the solid material is heated from about 300° C. below the forging temperature to the forging temperature, the solid material is transversally spline-rolled until weakenings are created in the core zone (3) of the solid material and the sold material is torn open. Two mandrels (5,6) are forcibly introduced into the center of the bar-shaped solid material during the rolling process, and then one mandrel is retracted while the other mandrel continues advancing so as to produce a tubular part. A transversally spline-rolled rotationally symmetrical hollow part, especially a shaft, which is produced accoridng to noted method can be embodied as a transmission shaft, camshaft, drive shaft, output shaft, starter shaft, hollow shaft, or can bea preform for molded parts and the like.
