Description
Technical field
The utility model relates to diesel oil for locomotive machine drive technology field, particularly the semi-rigid shaft coupling structure of a kind of diesel oil for locomotive machine steel-sheet type.
Background technique
On current domestic diesel engine of locomotive, majority is all used elastic coupling, uses more elastic coupling roughly to have two kinds: rubber elasticity shaft coupling, elastic damping coupler.
Rubber elasticity shaft coupling is because elastic element adopts rubber, thereby causes whole parts short working life, the processing technology of rubber required highly in course of working simultaneously, and encapsulating difficulty is large, and later maintenance cost is high.
Elastic damping coupler complex structure, cost is very high, and because need organic oil to carry out oil circuit, causes diesel engine complex structure, increases the processing cost of diesel engine; For sealing lubricating oil, use O type O-ring seal, easily premature aging is out of shape and causes leakage of oil, and reed and the lubricated of splined shaft friction pair are impacted, and makes it too early wearing and tearing, affects the working life of whole parts.
Therefore, also need elastic coupling structure to further improve, so that cost is more reasonable, the life-span is longer, uses also more safe and reliable.
Model utility content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of diesel oil for locomotive machine steel-sheet type semi-rigid shaft coupling structure.
The technical solution adopted in the utility model is such: the semi-rigid shaft coupling structure of a kind of diesel oil for locomotive machine steel-sheet type, comprise generator end spindle, generator end adpting flange, also comprise the crankshaft output end of bent axle, crankshaft output end flange, described crankshaft output end flange is fixedly connected with driving disc with nut two by connecting bolt two, described generator end adpting flange is fixedly connected with driven disc by stay bolt, in the end of described crankshaft output end puts interior guide ring and is inserted into generator end spindle endoporus after outer guide ring again, realizing interference fit is connected, steel disc group is set between driving disc and driven disc, then pass through connecting bolt one and nut one by driving disc, steel disc group, driven disc is connected in series fixing successively.The technical solution of the utility model is simple in structure, utilizes steel disc group as elastic coupling element, can play the effect of certain buffer shock-absorbing, and bearing capacity is large simultaneously, contact performance good, reliability is high; The thickness of steel disc group is adjusted as required.On described driving disc, be processed with gear ring, in the time of needs jiggering, engage with the gear on barring mechanism, can coil dynamic crankshaft.
Such scheme is further improved and preferably, and described connecting bolt one first puts in the bolt hole that then lead ring insert driving disc.Connecting bolt is special hinged bolts, and itself and lead ring endoporus adopt little Spielpassung, play guide-localization effect, can ensure the relative position requirement between driving disc, driven disc, steel disc group.Lead ring cylindrical and driving disc adopt large Spielpassung simultaneously, after connecting bolt one compresses, in the time of diesel engine High Rotation Speed, due to reasons such as assembling and machining errors, easily cause actual main generator and diesel engine disalignment, can adjust in time by the large gap between lead ring and driving disc like this, make up the shortcoming of semi-rigid connection, meet the safe handling that whole axle is.
Such scheme is further improved and preferably, between described steel disc group and driven disc, is provided with packing ring two.There is the processing cost that can effectively reduce driven disc in packing ring two, after wearing and tearing, replacement cost is low.
Such scheme is further improved and preferably, between described driven disc and nut one, is provided with packing ring one.Packing ring one can ensure that connecting bolt one locks effectively.
