Background technique
In the middle of existing motor, the crank pulley in crankshaft front end mechanism usually adopts interference fit or is arranged on crankshaft front end by bolt.Wherein, when crank pulley adopts interference fit to be arranged on crankshaft front end, its moment of torsion transmitted is less, in order to ensure the requirement of crank pulley transmitting large torque, need the enlarged diameter of crankshaft front end, the general arrangement of motor head can be affected like this, can not adapt to day by day to increase and under complete machine arrangement space deflation condition at motor cost pressure, the demand of motor compact structure; When crank pulley is arranged on crankshaft front end by bolt; bent axle in motor car engine itself has and certain certainly shakes frequency; motor operationally; bent axle can produce vibrations; belt pulley is fixed on the end face of bent axle by bolt presses; belt pulley and bent axle easily produce loosening; usual meeting adds at bolt link position loosens gasket construction; but common pad is under working long hours; have impurity corrosion; still can not solve belt pulley and be connected the problem loosened with crankshaft front end, the transmission of moment of torsion can be affected like this, reduce the working efficiency of motor.
Model utility content
The purpose of this utility model be in order to solve existing engine belt pulley adopt bolt be arranged on crankshaft front end time, engine operation bent axle produces vibration, produce to making belt pulley and bent axle and loosen, the problem of the loss causing moment of torsion to transmit, and then a kind of crank shaft bolt gasket construction is provided.
The technical solution of the utility model:
A kind of crank shaft bolt gasket construction comprises crank pulley connecting bolt, check washer and protecting cover, check washer body is provided with the first relative attachment face and the second attachment face, the first described attachment face is provided with groove, the surface of the second attachment face is provided with the decorative pattern skid resistant course of " concavo-convex " shape, described protecting cover is the taper protective equipment that one is provided with " train of dress " shape, crank pulley connecting bolt is arranged in the taper train of dress of protecting cover, protecting cover lower end is provided with check washer, and the first attachment face of described check washer contacts with the lower end surface of protecting cover.
Preferred: the cross section of the groove that the first attachment face of described check washer is provided with is triangle or rectangle.
Preferred: the distance of the head flanges face outward edge that the rim inner diameter of described groove is greater than crank pulley connecting bolt at least 2mm.
Preferred: the flange outside diameter of described groove is less than the distance of check washer outer circular edge at least 2mm.
Preferred: the whole height H after described crank pulley connecting bolt, check washer and protecting cover installation is 5-10mm.
The utility model has following beneficial effect: a kind of crank shaft bolt gasket construction of the present utility model, it is simple and reasonable, meet the installation requirement of bent axle and crank pulley, one deck taper protective equipment is provided with in the centre of bolt and pad, when can effectively prevent bent axle and belt pulley from working, the erosion such as dust, impurity, increase engine operating efficiency, concave channels is provided with again on the attachment face of pad, be convenient to the attachment face identifying pad, avoid assembler's misloading, enhance the installation soundness of bent axle and belt pulley, improve the working efficiency of motor.The utility model has little, the compact structure of taking up room, the feature such as easy for installation, effectively can solve bent axle and be connected the problem loosened with belt pulley.
