Abstract
The utility model discloses a kind of tapered sleeve structural formula vibration damper, its structure is: between bent axle and vibration damper outer ring, be provided with tapered sleeve, and the exterior edge face of tapered sleeve is provided with pad, makes pad and tapered sleeve that the first main journal of vibration damper and bent axle is adjacent to by crankshaft nut.Make to form interference fit between vibration damper outer ring, tapered sleeve and bent axle three by spindle nut fastening force.Tapered sleeve is provided with vertically and cracks, and object makes tapered sleeve in tensioner process, ensure degree of fitting tightly between vibration damper and tapered sleeve, bent axle.During assembling, tighten crankshaft nut, crankshaft nut promotes tapered sleeve, and tapered sleeve moves axially along bent axle.Because the gap between bent axle and vibration damper is fixing, when tapered sleeve embeds between bent axle and vibration damper, along with the increase of tapered sleeve magnitude of interference, tapered sleeve meeting tensioner bent axle and vibration damper, complete the installation of vibration damper and bent axle.Adopt the fixing tapered sleeve structural vibration reduction device of tensioner to reduce crankshaft nut tightening torque, make vibration damper easier for installation, reach good assembling effect.
Description
Technical field
The utility model belongs to engine components manufacturing technology, is specifically related to a kind of tapered sleeve structural formula damper means being applicable to motor.
Background technique
Stressed complexity during engine crankshaft High Rotation Speed, and bear the percussion of stress alternation simultaneously, this impact will make bent axle produce torsional vibration.The excessive motor smoothness that will cause of torsional vibration amplitude is poor, can cause the pernicious faults such as crankshaft breakdown time serious.For cutting down the torsional vibration of bent axle, generally install vibration damper additional at crankshaft front end.The principle of vibration damper is, be the amplitude during resonance of abatement bent axle and be provided with coasting body, and one end of coasting body is in cantilever end.If vibration damper is directly fixed on crankshaft front end, need very large tightening torque, the installation of this fastening structure to vibration damper brings many troubles, should manage to improve the structure of vibration damper.Proposition of the present utility model easyly can complete the assembly process of vibration damper.
Summary of the invention
The purpose of this utility model is, provides a kind of motor tapered sleeve structural formula vibration damper, when do not need very large tightening torque, meet the matching requirements of vibration damper.
The technological scheme adopted for realizing this object the utility model is: between bent axle and vibration damper outer ring, be provided with tapered sleeve, the exterior edge face of tapered sleeve is provided with pad, makes pad and tapered sleeve that the first main journal of vibration damper and bent axle is adjacent to by crankshaft nut.Make to form interference fit between vibration damper outer ring, tapered sleeve and bent axle three by crankshaft nut fastening force.
The beneficial effect of feature of the present utility model and generation is: the tapered sleeve structural vibration reduction device adopting tensioner to fix substitutes the mounting type that single crankshaft nut compresses vibration damper, reduces crankshaft nut tightening torque, can reduce labor intensity, enhance productivity.Make vibration damper easier for installation, reach good assembling effect.
Accompanying drawing explanation
Fig. 1 theory and structure sketch of the present utility model.
Fig. 2 is the structural drawing of tapered sleeve in the utility model.
Embodiment
Structure of the present utility model to be further described by specific embodiment below in conjunction with accompanying drawing.The structure of tapered sleeve structural formula vibration damper is: between bent axle 1 and vibration damper outer ring 2, be provided with tapered sleeve 3, and the exterior edge face of tapered sleeve is provided with pad 4, makes pad and tapered sleeve that the first main journal 6 of vibration damper and bent axle is adjacent to by crankshaft nut 5.Make to form interference fit between vibration damper outer ring, tapered sleeve and bent axle three by spindle nut fastening force.Tapered sleeve is provided with vertically and cracks, and object makes tapered sleeve in tensioner process, ensure degree of fitting tightly between vibration damper and tapered sleeve, bent axle.
Vibration damper is made up of outer ring and inner ring, is provided with vibration isolation rubber between vibration damper outer ring and vibration damper inner ring.By installing tapered sleeve additional between vibration damper outer ring and bent axle, complete the connection of vibration damper and bent axle.During assembling, when tightening crankshaft nut, crankshaft nut promotes tapered sleeve, and tapered sleeve moves axially along bent axle.Because the gap between bent axle and vibration damper is fixing, when tapered sleeve embeds between bent axle and vibration damper, along with the increase of tapered sleeve magnitude of interference, tapered sleeve meeting tensioner bent axle and vibration damper, complete the installation of vibration damper and bent axle.Due to gap that tapered sleeve cracks, in assembling, tapered sleeve is with vibration damper Internal Hole Deformation spreading.Except ensureing that the laminating connected is outside one's consideration, the amount of rising also can be prevented excessive and the vibration damper that causes damages.By installing tapered sleeve additional, making crankshaft nut screw the too large moment of torsion of Shi Buxu, just can meet the usage requirement of vibration damper.The utility model effect in 4102 type diesel engine is very good.
