Fault Analysis and Improvement of Gearbox Gear Switch

【Abstract】In order to eliminate fault of gearbox gear switch in use, this paper, by correlating with the faulty parts in the use of gear switch, analyzed oil intake problem caused by poor sealing of gear switch, switch on-and-off failure under actuating pressure as well as contact ablation, to further improve the performance of the gear switch. The verification results show than the proposed scheme can effectively solve the problems existing in the use of the gear switch.

Key words:  Gearbox, Gear switch, Fault diagnosis, Control strategy optimization
