Abstract
The present invention relates to an elastic shaft coupling of a diesel engine. A radial oil returning hole (7) is provided at one end of a side plate (17) in a key groove (8), a groove (13) corresponding to the key groove (8) is radially arranged on the inner side of an end cover (14) on the side of a flange (16), an I-shaped separating block (3) with a central through hole is provided on one side of the end of the flange (2) near to a spline shaft central through hole (12), forming an oil returning cavity (5) being opposite to a key groove oil returning hole (7), and an axial oil returning hole (4) connected with the oil returning cavity (5) is provided on the outer end of the separating block (3) to form a cooling and circulation loop of the oil lubrication. The present invention can prevent the oil leakage caused by the early aging and distortion of the sealing rubber ring, improve the circulation to the spring leaf and the spline shaft friction pair, and avoid the early friction.
Description
Technical field
The invention belongs to Diesel Engine Technique Field, relate in particular to a kind of novel diesel engine elastomeric coupling.
Background technique
In high-power diesel engine power unit, usually between the output terminal of crankshaft of diesel engine and load, an elastic coupling is set, to improve abominable operating mode.But there are inertial mass problems such as lubricating oil leakage, the aging distortion of rubber ring, the wearing and tearing too early of reed splined shaft in the reed-type elastic coupling of prior art in application.This is because the middle endoporus of the pressure machine oil of the inner oil pocket of crankshaft of diesel engine by splined shaft is transported to elastic coupling inside, because elastic coupling seals, internal gas can't be emitted, and machine oil can not be full of inside, just can not obtain well lubricated like this between reed and the splined shaft.On the elastic coupling side plate, be provided with the venting screw plug afterwards, when for the first time elastic coupling being installed, the air of inside got rid of, and made machine oil can be filled in the whole inner chamber of elastic coupling by screw plug.Even but like this, machine oil still can't be in internal flow, in use the fricative heat between reed can make the too high even gasification of oil temperature, and rubber ring very easily is out of shape, wears out and by cavitation pitting, causes the too early leakage of oil of elastic coupling in this case.Formed friction pair between reed and the splined shaft, under lubricated cooling condition of poor, also to transmit very big moment of torsion, contact position between reed and the splined shaft also can produce localized hyperthermia, cause this place's metallic material mechanical property to reduce greatly, wearing and tearing too early occur and progressively enlarge failure area and degree, a reed at first damages, and its mechanical load is shared again on other reed, so vicious circle, other reed also can damage very soon in succession.In order to address these problems, be provided with the oil circulation loop in some scheme elastic couplings, for example more famous lid Si Linge elastic coupling, the keyway middle part of its splined shaft has the radially oil inlet hole that is communicated with the central through bore of axle, bilateral symmetry at axle has axial spill port, so just realize circulating of machine oil, improved the lubricated and cooling of elastic coupling inside to a certain extent.But because oil inlet hole is opened the middle part at keyway, machine oil can only flow to the one end, and keyway still has half to be in the circulation dead band, and the wearing and tearing at these positions are still very serious.Open axial spill port in addition on splined shaft, its technology is also comparatively complicated, and intensity is also had some influence.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, and the novel diesel machine elastic coupling that a kind of lubricated cooling is good, prolong working life is provided.
The objective of the invention is existing like this: a kind of diesel engine elastomeric coupling, output flange and side plate clamp the equally distributed wedge shape reed group of being separated by support block in the taper sheath by bolt, the splined shaft that has central through bore that one end has input flange inserts from side plate one side, the inner of each reed group embeds in the keyway of splined shaft, have radially spill port by side plate one end in the keyway, the inboard radially direct of the end cap of the output flange side groove corresponding with keyway, lean on input flange end one side to pack at the splined shaft central through bore and have the I-shaped spacing block of central through bore, described spacing block forms the oil back chamber that communicates with spill port with the inwall of splined shaft, has the axial oil outlet that is communicated with oil back chamber on the outer end of spacing block.
After adopting the solution of the present invention, elastic coupling inside has formed a good oil circulation loop, and does not have the dead band.Machine oil has into and has, and the high temperature of inside is taken away, and is back in the oil sump of diesel engine, so just can prevent to cause leakage of oil because of O-ring seal premature aging distortion, has also improved lubricated to reed and splined shaft friction pair, has avoided too early wearing and tearing.
