AN EXPERIMENTAL STUDY ON THE TRANSIENT TEMPERATURE TEST OF THE PLANETARY GEAR REDUCER OF THE EPBM

摘要

A temperature test apparatus has been designed to measure the temperature rise of the planetary gear train. The experimental platform integrated the temperature test system, siemens operating system and industrial personal computer (IPC). The temperatures of various locations have been investigated under rated condition and the oil temperature rise time under different speed was estimated. The experimental results indicated that the temperatures of the super-speed planetary gear train (PGT) of the earth pressure balance shield machine (EPBM) rise quickly than the low-speed PGT and the speed has significant influence on the temperature of the PGT. Through comparison the oil temperatures under reverse direction and forward direction, the direction of the motor has little influence on the temperature of the PGT.
