Description

Technical Field

[0001] The utility model relates to a wireless temperature measuring device for a transmission component. Background Art

[0002] At present, there are various transmission components in the mechanical field. Taking a spline transmission component as an example, in the spline transmission component, an inner spline and an outer spline cooperate to form a transmission connection part. When the inner spline and the outer spline transmit torque in the transmission connection part, there is friction, which will cause the temperature of the transmission connection part to rise. The increase in temperature will affect the dimensional fit accuracy and mechanical properties of the transmission connection part, and further cause mechanical failures of the spline transmission component. Therefore, in order to keep the spline transmission component running normally, it is necessary to measure the temperature of the transmission connection part in real time so as to take preventive maintenance measures in time when the temperature rises abnormally. However, the existing temperature measuring instruments can only detect the temperature of the transmission connection part when the spline transmission component stops rotating, and cannot detect the temperature of the transmission connection part in real time without stopping the machine.
