(1) Determination of ambient temperature
①Place a thermometer at a distance of 1.5m from the surface of the reducer under test, and the height of the thermometer measuring point from the ground is the same height as the axis of the reducer.
②The placement of the thermometer should not be affected by external radiant heat and airflow.
③ The reading of the ambient temperature value and the reading of the working temperature value should be carried out at the same time.
(2) Determination of working temperature
① The measurement of the temperature rise of the reducer under test is usually carried out at the same time as the measurement of the bearing capacity and transmission efficiency of the reducer, or it can be carried out separately.
② When the tested reducer meets the requirements of 5288.3 in JB/T8.2.3, read the rated speed and rated input of the reducer.
Operating temperature at power.
