Precision planetary reducer temperature rise test method

The temperature rise of the reducer should be measured in a room that is not affected by the external temperature. The indoor ambient temperature should be within the range of 5~40°C. The indoor air should circulate freely, and forced circulation is not allowed. 

Environmental conditions 1. The temperature rise of the planetary reducer should be measured in a room that is not affected by the external temperature. The indoor ambient temperature should be within the range of 5~40°C. Should the indoor air circulate freely? Forced circulation is not allowed. . 2. Temperature measurement point The temperature measurement point should be selected at a position where the thermometer can touch the lubricating oil of the planetary reducer. The graduation value of the thermometer is 0.5°C.

 2. Measurement method 1. Determination of working temperature The measurement of the temperature rise of the tested reducer is usually carried out simultaneously with the measurement of the load capacity and transmission efficiency of the reducer, or it can also be carried out separately. When the tested reducer meets the requirements, read the deceleration The operating temperature of the machine at rated speed and rated input power. 2. Determination of ambient temperature Place a thermometer 1.5m away from the surface of the tested reducer. The height of the thermometer measuring point from the ground is equal to the axis of the reducer. The reading of the temperature value and the reading of the working temperature value should be carried out at the same time. 

3. Calculation of temperature rise The temperature rise is calculated according to the following formula:  In the formula: Δt——The temperature rise of the reducer, ℃ The working temperature of the cycloid reducer at rated speed and rated input power, ℃ The ambient temperature, ℃. t2——t1——Δt=t1–t2
