The Short-Time Transient Temperature Rise of Self-Contained Oil-Filled Cable Systems with Particular Reference to Oil Demands

Conical friction surface is a novel configuration for friction plate in transmission. Numerical FEA models for transient heat transfer and distribution of conically grooved friction plate have been established to investigate the thermal behavior of the conical surface with different configurations. The finite element method is used to obtain the numerical solution, the temperature test data of conical surface are obtained by the friction test rig. In order to study and compare the temperature behavior of conically grooved friction plate, several three-dimensional transient temperature models are established. The heat generated on the friction interface during the continuous sliding process is calculated. Two different pressure conditions were defined to evaluate the influence of different load conditions on temperature rise and the effects of conical configuration parameters on surface temperature distribution are investigated. The results show that the radial temperature gradient on conical friction surface is obvious. The uniform pressure condition could be used when evaluating the temperature rise of conically grooved friction plate. The increase of the cone height could improve the radial temperature gradient of the conically grooved friction plate.

Temperature Test

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.
