Content
This paper presents a measuring technique, a test result and a finite element analysis result of a surface temperature of rotary lip seals. A thermocouple embedded in the surface of a shaft and radio transmission systems provide wireless measurement for the temperature of the rotary shaft, which is driven up to 6000 rpm. Relationships between shaft temperature, lip temperature and sliding speed were shown. Torque of PTFE coated seals is about 23 % lower than that of conventional seals at 22 m/s. At that time, the shaft temperature of PTFE coated seals is about 7 K lower than that of conventional seals. And, Lip temperature of PTFE coated seals is about 1 K lower. In the analysis result, high temperature part of the shaft is larger than that of the lip, that is, heat is concentrated in the sealing edge of the lip. Temperature rise of the analysis result is consistent with those of the test result.
