The dataset provides the temperature measurements used for identification and validation in the publication "Lubricant Temperature Observer for Gearboxes in Industrial Robots". It was recorded with the presented experimental setup, which represents an industrial robot joint consisting of motor and gearbox and is equipped with three temperature sensors. These sensors measure lubricant, housing and environment temperature. The dataset is divided into two folders: "identification" and "validation". The folder "validation" contains subfolders for the three validation scenarios described in the paper: heat-up, long-term and cool-down. Each file contains one measurement with the desired motor velocity theta_dot in rad/s given in the file name. The measurement data is structured in five columns: time t in s, lubricant temperature T_L in °C, housing temperature T_H in °C, environment temperature T_E in °C, motor velocity theta_dot in rad/s and friction torque tau_f in N m. The MATLAB function "read_data.m" can be used to import the dataset into a MATLAB structure array. It is used in the MATLAB script "plot_figures.m" to plot the temperature measurements.
