peratures it may be necessary to heat the gear oil before switching on the drive unit or even during operation. In such cases, . . heating elements can be used. These heating elements convert electrical energy into heat which is conducted to the surrounding oil. The heating elements are located in protective tubes inside the housing, thus making it possible to replace them without draining the oilbeforehand. Complete immersion of the heating elements in the oil bath must be ensured. The heating elements can be controlled by temperature monitor which emits signal when minimum and maximum temperatures are reached; the signal requires amplification. 2 1 2 1 2 1 2 1 Fig. 1: Heating on gear units of types .., .. 1 Heating rod 2 Temperature monitor .. / ..
