Abstract
The invention provides a super high pressure automatic oiling device, which relates to the improvement in manufacture and maintenance technologies on a rail-mounted vehicle. The device is characterized in that: a hydraulic oil way together with a gear pump and a solenoid relief valve forms a first hydraulic system; an oil way outlet of the first hydraulic system is connected with a booster through a solenoid reversal valve to form a second hydraulic system; a direction increaser outlet is communicated with an oil outlet. The device has the advantages that: firstly, the adoption of an oiling press mounting wheel shaft overcomes shortcomings and defects of press mounting of the prior wheel shaft; secondly, the technology solves one of major process production technologies for Chinese production of high speed vehicles; thirdly, rejection rate is reduced, so production cost can be saved; work efficiency is increased and also products quality and stability can be improved; finally, the technology can be applied not only to railway locomotives but also to products production of other industries, and has extensive applications, market prospects and popularization values.
