Abstract:
The problem of worm gear heating is analysed in this paper. In most of cases, this heating has great impact on load capacity of worm gears, but in a great measure defines efficiency of worm gear transmission. Heating of worm gear is restricted by thermal power capacity of the gearbox. Thermal power capacity of the gearbox is defined as the biggest input power of the gearbox which could be transmitted by the gear unit, with the condition that power losses can be given to the surrounding without overheating of the gearbox, in the case of normal air temperature. Determination of the operating temperature represents the main problem for defining thermal power capacity of the gearbox. The highest operating temperature represents a limit until the gearbox (the oil in the gearbox) can be heated, but also in dependence of surrounding temperature (the ambient temperature where the gearbox operates). Influence of these temperatures is analysed in this paper.

Key words:
Operating temperature, ambient temperature, thermal power capacity, worm gear.
