Cooling arrangement for gear box, has oil cooler arranged between fan and gear box and arranged in sucked and/or delivered airflow of fan, where fan is located on shaft of gear box, and oil cooler is formed as oil-air-heat exchanger

摘要

The arrangement has a fan (1) e.g. axial blower, located on a shaft (4) i.e. driving shaft, of a gear box (3) or a shaft connected with the shaft of the gear box. An oil cooler (2) is arranged between the fan and the gear box and arranged in sucked and/or delivered airflow of the fan. The shaft of the gear box is connected with a rotor shaft of an electromotor in a torque-proof manner and/or connectable or separable over fluid connection. The oil cooler is formed as an oil-air-heat exchanger that is radially arranged around the fan.
