Oil Ring of EMU Gearbox Press in Position Detection Method Based on Press fit Curve
CRH(China Railways High speed) has been experiencing flourishing development in recent years, and the quality of high speed EMU (Electric Multiple Units) not only has an impact on China Railways operation security, but also concerns the international execution of the Belt and Road Initiative. Gearbox, as the key component of EMU bogie, bears high load and severe vibration, and due to its sophisticated structure, large amount of components and high precision of assembly, the maintenance of EMU gearbox is of substantial significance in the overhaul of the whole EMU. However, in the maintenance of EMU gearbox, traditionally it is impossible to make sure that the oil ring is in place after being press fitted, since the view has been blocked by the bearing cage. Therefore, a series of technical research has been carried out to study properties of the pressure fit curve of the press machine, as well as reveal the principle indicated by it. Eventually, an approach based on the press fit curve to determining whether the oil ring is in place has been devised.

Novel Automatic Demoulding and Feeding Device for Oil Seal Transfering Molding Press and Simulation Analysis
The production equipment of the small volume rubber oil seal is mainly the transfering molding press. To solve the problems of low efficiency, high production cost and low cleanliness in the process of transfering molding vulcanizing at present, this study designed a novel type of automatic demoulding and feeding device for oil seal transfering molding press, which was composed of start button, stop button, guide rail bracket, elevating mechanism, middle template, holder, frame box and skeleton releaser. The holder clamped the middle template, and the oil seal demoulding could be achieved by rotating the holder, which made the labor intensity of the workers is effectively reduced, and the labor force is liberated. Multiple skeletons can be placed simultaneously using skeleton releasers on the frame box, which avoids the impurity adsorption on the surface of the skeleton, ensures the quality of the oil seal, and effectively improves the work efficiency. The simulation analysis of the automatic demoulding and feeding device for oil seal transfering molding press was carried out in this study. The analysis results show that the deformation condition and stress distribution are consistent with the design results, and the the maximum stress is less than the expected result.
