摘要： A gear unit comprises shafts (101, 102) for connecting to an external mechanical system, at least one gear stage (103) between the shafts, a lubricant oil room (104) for storing lubricant oil, an oil channel (105) for transporting the lubricant oil from the lubricant oil room to the at least one gear stage, and an immersion heater (106) for heating the lubricant oil flowing in the lubricant oil room towards an inlet of the oil channel. The gear unit further comprises a mechanical flow guide (108) located in the lubricant oil room and configured to modify flow of the lubricant oil flowing towards the inlet of the oil channel so as to increase flow velocity of the lubricant oil on the surface of the immersion heater. The increased flow velocity on the surface of the immersion heater makes it possible to use higher heating power without damaging the lubricant oil.

摘要： A gear system comprises at least one gear stage (103), a pump system (104) and oil channels (105) for circulating a first lubricant oil flow via first elements (107a-107c) of the gear stage and a second lubricant oil flow via second elements (109) of the gear stage, and an oil conditioning system (106) for controlling temperatures (T1, T2) of the first and second lubricant oil flows so that the temperatures of the first and second lubricant oil flows are different from each other and flow rates (F1, F2) of the first and second lubricant oil flows are different from each other. Thus, it is possible to utilize for example the fact that bearings do not need as much oil flow as gear wheels but, on the other hand, lowering oil temperature of the bearings provides more advantages than lowering oil temperature of the gear wheels.
