Gear thermal power
Part 2. Calculation of thermal carrying capacity
1 Scope
This section GB /Z22559 proposed a method to determine the thermal carrying capacity of gears, including the actual conditions of the gear unit test
set. The approach taken was to measure the power loss, measure the heat dissipation, or both and measure the oil sump in the spilled oil lubrication gearbox
The quasi-stable temperature.
GB /Z22559 described in this section of the power loss and heat dissipation of all components of the calculation method is considered as an option
Choose the method.
