Description
Technical field
The utility model relates to a kind of high pressure oil pump transmission shaft seal, the high pressure oil pump transmission shaft seal of the steyr of more specifically saying so diesel engine.
Background technique
WD615 series steyr diesel engine, the oil sealing leakage of oil of its high pressure oil pump transmission shaft is the outstanding difficult problem that urgency is to be solved always, since steyr diesel engine front end housing for timing gear intermediate gear shaft adopts pressure lubrication, the overstriking of high pressure oil pump transmission shaft and increases oil sealing base, the ratio of the seepage oil of its transmission shaft oil sealing is more increased, reduced the reliability of complete machine, and very difficult when oil sealing is installed, cause manufacturing efficiency low, both have influence on the output of manufacturer, had influence on appearance quality again.
Goal of the invention
The purpose of this utility model provides a kind of high pressure oil pump transmission shaft seal that can stop a transmission shaft seepage oil difficult problem.
In order to realize above-mentioned purpose, this high pressure oil pump transmission shaft seal, comprise gear chamber and the air compressor crankcase of fixedlying connected with gear chamber, the high pressure oil pump transmission shaft by gear chamber bearing and air compressor crankcase bearings in gear chamber inner chamber and air compressor crank box cavity, and it is overhanging from the air compressor crankcase end, intrinsic lining is overlapped at the end position place that is positioned at the air compressor crank box cavity at the high pressure oil pump transmission shaft, oil sealing base is housed on air compressor crankcase, on the inner cylindrical surface of oil sealing base oil sealing is installed, form sealing surface between oil sealing and the lining, its structural feature is to increase an oil baffle disc that is sleeved on the lining between oil sealing and air compressor crank axle box bearing.
Leave slight clearance between above-mentioned oil baffle disc and the oil sealing base, this slight clearance can make lubricant mist enter on the sealing surface between oil sealing and the lining.
Above-mentioned oil baffle disc is fastening by the gland nut and the air compressor crank axle box bearing that are sleeved on the high pressure oil pump transmission shaft section of stretching out.
The installation of oil sealing for convenience, the installation quality of raising oil sealing, as the improvement to this high pressure oil pump transmission shaft seal, the outer end section of the inner cylindrical surface of above-mentioned oil sealing base is provided with chamfering.
High pressure oil pump transmission shaft seal described in the utility model, owing between oil sealing and air compressor crank axle box bearing, increased an oil baffle disc, thereby when work stopped by oil baffle disc through the lubricant oil that the gap of air compressor crank axle box bearing flows into, the overwhelming majority can not flow to the sealing surface place of oil sealing, the lubricant oil that is thrown away by oil baffle disc, small part from the chamfering water clock of oil sealing base the inner in the gap of oil sealing and oil baffle disc, for the reliably working of oil sealing provides an amount of lubricant oil.The outer end section of the inner cylindrical surface of oil sealing base is provided with chamfering, and oil sealing is packed into from this chamfering during installation, and is easy for installation, improved the assembly quality of oil sealing on the one hand, avoid the oil seepage phenomena that causes because of assembly quality is low, can enhance productivity significantly on the other hand, reduce production costs.
By above narration as can be known, high pressure oil pump transmission shaft seal described in the utility model has solved this difficult problem of high pressure oil pump transmission shaft oil sealing seepage oil that exists for many years effectively.
Seal arrangement described in the utility model can be applied on similar oil seal structure.
