Summary: This standard specifies a gear method of determining the thermal load capacity, including the determination of the actual conditions of the gear unit. The approach taken has measured power consumption, measuring heat, or both measurements, or to determine the quasi- steady temperature of the oil pool splash oil lubrication in the gearbox. All the components of the calculation of the power loss and heat dissipation of GB/Z 22559 described in this section is considered to be the method of choice.

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. 2 symbols, units and superscripts GB /Z22559 symbols used in this section, units and superscripts are listed in Table 1.
