HIGH SPEED GEAR WITH OIL LUBRICATION, ESPECIALLY FOR ENVIRONMENTALLY SEALED RAILWAY DRIVING MECHANISMS

摘要

The invention relates to a high speed gear with oil lubrication, wherein oil recycling ducts (8) lead from labyrinth chambers of contactless shaft seals (6) to the crankcase of the gear casing (3). According to the invention, the oil recycling ducts (8) lead to regions (10) where a negative pressure is adjusted during operation automatically and independently of the gear rotati on direction.
