Installation and application of the yielding coupling on crankshaft:

Yielding coupling is mounted on the free end of crankshaft of diesel engine, and provides lubrication from crankshaft of diesel engine center to yielding coupling Oil；Inspection before yielding coupling installation, all oilholes must degrease and other impurity；Splined shaft 6, flange 12, jiggering O-shaped rubber seal on wheel 3 must not be pulled or be damaged, and must coat lubricating oil；The deflation of yielding coupling, equipped with elasticity connection The diesel engine of axis device, before first time test running, it is necessary to deflate to yielding coupling.Its method is to rotate elastic shaft coupling Device makes a bleeder screw 21 thereon be in highest position, and unloads bleeder screw 21, with diesel engine or the lubricating oil of gear-box Oil pump is oil-filled to yielding coupling, and the minimum oil pressure at yielding coupling oil inlet should be 0.25MPa, when deflation screw hole has oil spill When out, then the deflation of yielding coupling and oil-filled good puts butterfly elastic washer, tightens bleeder screw 21, to prevent pine Dynamic oil leak；The lasting deflation of yielding coupling, yielding coupling are provided with oil nozzle, have a small amount of oil stream to go out by it, remain in Air in yielding coupling will be brought out with oil, to reach lasting deflation.Yielding coupling is opened and inspect every time, will be cleaned Oil nozzle, but do not allow to expand the logical dipstick cun of oil nozzle；Inspection after first time test running, when yielding coupling is mounted on diesel engine When outside body, should check the outer surface of yielding coupling, see its whether the trace of oil leak, if after the damage of O-shaped rubber seal, Radial oil stain can be shown on splined shaft 6, jigger wheel 3, flange 12, cover board 13, connecting flange 19.

The assembly and disassembly methods of yielding coupling: the disassembly of yielding coupling unloads the bolt on lower flange 12, removes connecting flange 19, the bolt on lower cover plate 13 is unloaded, cover board 13 is removed, unloads the bolt on bearing gland 15, bearing gland 15 is removed, removes flower Key axis 6；The second kingbolt 26 on jigger wheel 3 is unloaded, jigger wheel 3 is removed.

Assembling process is similar to disassembly process, and only sequence is on the contrary, the following several points of another supplement: carefully clean each zero Part is provided with the position of O-shaped rubber seal in parts such as jigger wheel 3, splined shaft 6 and flanges 12, including spline rooved face applies Upper molybdenum disulphide grease；

Molybdenum disulphide grease carefully is coated to all O-shaped rubber seal, and must not damage or pull sealing ring；

The application with the first saucer washer, the second saucer washer and third saucer washer convex surface connecing upward In contacting surface and bolt head coats " LOCTITE242 " and " LOCTITE271 " glue respectively, to locking fastening；Carefully remove oil inlet Dirt on mouth and oil nozzle；It whether with one heart to check elastomeric components 1, jigger wheel 3 (2) and flange 12, and corrects its concentricity.

Yielding coupling is illustrated using operating condition: the minimum oil pressure at yielding coupling oil inlet is 0.1MPa, elasticity Shaft coupling environment temperature allowable is that the oil temperature no more than 90 DEG C, at yielding coupling oil inlet is no more than 60 DEG C, yielding coupling It should be stored in cleaning, drying and draughty warehouse, oil sealing maintenance validity period is six months after factory, in Special Ring The yielding coupling to work under border is got in touch in order Shi Yingyu manufactory.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution The range of scheme.
