Explanation: Measurement method of temperature rise of cycloid reducer

The cycloidal pinwheel reducer is reliable in use and has a long service life. The main parts are made of bearing steel material, which is quenched (HRC58-62) to obtain high strength, and part of the transmission contact adopts rolling friction, so it is durable and has a long service life.So what are the methods for measuring the temperature rise of the cycloid reducer?

Measurement method of temperature rise of cycloid reducer:

JB/T5288.1—91

1 Subject content and scope of application

This standard specifies the environmental conditions, measurement methods and determination of the results of the measurement of the temperature rise of the cycloid reducer (hereinafter referred to as the reducer).

This standard applies to reducers lubricated with lubricating oil.

2 Reference standards

JB/T5288.3 Determination method of bearing capacity and transmission efficiency of cycloid reducer

3 Environmental conditions and temperature measurement points

3.1 Environmental conditions

3.1.1 The measurement of the temperature rise of the reducer should be carried out indoors that are not affected by the external temperature, and the indoor ambient temperature should be within the range of 5 to 40°C.

3.1.2 Indoor air should circulate freely, and forced circulation methods are not allowed.

3.2 Temperature measuring point

The temperature measurement point should be selected where the thermometer can touch the lubricating oil of the reducer.

4 Thermometer

The graduation value is 0.5℃

5 Measuring method

5.1 Determination of working temperature

5.1.1 The measurement of the temperature rise of the measured reducer is usually carried out at the same time as the measurement of the load capacity and transmission efficiency of the reducer, or it can be carried out separately.

5.1.2 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.

5.2 Determination of ambient temperature

5.2.1 Place a thermometer at a distance of 1.5m from the surface of the reducer to be tested, and the height of the thermometer measuring point from the ground is equal to the height of the axis of the reducer.

5.2.2 The placement of the thermometer should not be affected by external radiant heat and airflow.

5.2.3 The reading of the ambient temperature value and the reading of the working temperature value should be carried out at the same time.

6 heating calculation

The temperature rise is calculated as follows:

Δt=t1t2

In the formula: Δt—the temperature rise of the reducer, C;

t1—The working temperature of the reducer at rated speed and low rated input power, C;

t2—ambient temperature, C.

7 Judgment of test results

The determination of the temperature rise test results shall comply with the provisions of the national standard "Cycloidal Pinwheel Reducer".
