Abstract
An oil thrower for an exhaust-gas turbocharger. The oil thrower has at least one first ring shoulder and one second ring shoulder. Formed between these two ring shoulders is an oil collection space. The lubricant is collected in this oil collection space at low rates of rotation. The oil thrower prevents the lubricant from ending up on the turbine wheel.
Claims21
An oil thrower for an exhaust-gas turbocharger in which a compressor is connected by a shaft with a turbine and with an oil thrower;
- the lubricant being drained off from a bearing of the shaft by the oil thrower, wherein at least two radially extending ring shoulders are arranged on the oil thrower.
An oil thrower for an exhaust-gas turbocharger in which a compressor is connected by a shaft with a turbine and with an oil thrower, lubricant being drained off from a bearing of the shaft by the oil thrower, wherein the oil thrower is completed from two individual oil throwers that are inextricably connected to each other.
An exhaust gas turbocharger assembly comprising:
- a turbine wheel,
- a turbine shaft rotatably fixed to the turbine wheel,
- a bearing rotatably supporting the turbine shaft at a location spaced axially from the turbine wheel,
- means for supplying lubricating oil under pressure to the bearing, and
- an oil thrower disposed surrounding the turbine shaft at an axial location between the bearing and the turbine wheel, said oil thrower including first and second radially extending ring shoulders defining one oil collection space therebetween.
