Abstract
The utility model relates to a belt pulley of an engine crankshaft flow forming absorber. The belt pulley comprises a belt pulley body, a hub and a signal panel which form a whole through flow forming. An inertia ring is assembled in a cavity of the hub, a rubber ring is arranged between the belt pulley body and the inertia ring, a protrusion is arranged on the middle portion of an inner surface of the belt pulley body, a pit is arranged on an outer surface of the corresponding inertia ring, and the rubber ring is then arranged between the belt pulley body and the inertia ring. The protrusion on the inner surface of the belt pulley body is made of 08A1 plates which are thickened from the thickness of 4mm to the thickness of 5.8mm through flow forming, and then the protrusion is manufactured. The belt pulley guarantees torsion force and axial force of an automobile engine during high-speed revolution, enables the inertia ring to be free of dropping, adopts the 08A1 plates with the thickness of 4mm to thicken the thickness of the protrusion on the inner lateral face of the belt pulley body to be 5.8mm, then manufactures to the protrusion into curvilinear for assembly, is formed by flow forming signal gears, lightens weight of an absorber assembly to be one third, guarantees product quality while lightening the weight, reflects automobile light weight, and achieves effects of energy conservation and emission reduction.
Description
Technical field
The utility model relates to the motor car engine component, specifically is engine crankshaft spinning vibration damper belt pulley.
Background technique
Along with developing of automobile industry, China has become second largest energy-consuming state, and saving energy consumption is each engine works' most important thing.
Domestic existing technical pattern is as shown in Figure 1, the big about-face engine crankshaft of this structure vibration damper performance and weight.Its structure is that belt pulley (foundry goods), wheel hub (foundry goods), rubber and signal panel (08AL) are formed; Yet foundry goods produces pore, shrinkage porosite, influences the defective existence of intensity; The processing reject rate is higher; Belt pulley, wheel hub and rubber ring were assembled before this, were assembling with signal panel then, and efficient is lower.
External engine crankshaft vibration damper is applied; As shown in Figure 2, be belt pulley, wheel hub, signal panel composition one, accomplish through spinning; Assembling completion with rubber ring, inertia rings then; Manufacturing efficiency is high, and reject rate is lower, does not exist because of defectives existence such as foundry goods generation pore, shrinkage porosites.Difficult point is that local spinning thickens technology, and conventional spinning wheel slot thickness has only 3.5mm, and quiet moment of torsion can meet the demands during the assembly assembling, but when high engine speeds is rotated, receives the effect of motor axial force, and inertia rings comes off easily, breaks motor head.
At present external vibration damper assembling rubber compression ratio has only 30%, and rubber and metal lean on binder to guarantee rotation torque power and bent axle axial force fully; Gluing of surfaces is handled very strict, and technology is comparatively complicated, does not domesticly also pass a test at technique for sticking, and it is qualified less than 100% to cross.
Summary of the invention
The utility model can not come off inertia rings in order to protect the safety of motor, reduces the accumulative total assembly error, a kind of engine crankshaft spinning vibration damper belt pulley of special proposition.
The technological scheme of the utility model does for this reason; Engine crankshaft spinning vibration damper belt pulley comprises that belt pulley, wheel hub, signal panel are as a whole through being spun into, and is equipped with inertia rings in the die cavity of wheel hub; Be provided with rubber ring between belt pulley and the inertia rings; It is characterized in that: the internal surface middle part at belt pulley is provided with convexity, and the outer surface of corresponding inertia rings is provided with depression, is provided with rubber ring between belt pulley and the inertia rings again.
Improvement to such scheme is: the convexity of said belt pulley internal surface is to adopt the local spinning of the thick 08Al plate of 4mm to thicken 5.8mm, is processed into protruding then.
Beneficial effect:
The utility model is provided with convexity at the internal surface middle part of belt pulley; The outer surface of corresponding inertia rings is provided with depression; Be provided with rubber ring between belt pulley and the inertia rings again, guaranteed rotation torque power and the bent axle axial force of motor car engine when high speed rotating, make inertia rings can not come off.
The utility model is to form a body and function spinning to wheel hub, belt pulley, signal panel to accomplish weight saving 1/3rd; Spinning thickens to cut protects rotation torque power and the bent axle axial force of motor car engine when high speed rotating; Engine luggine and noise obviously improve; Improving new structure is to bring up to 50% to the rubber compression ratio, increases Curve Machining, leans on the frictional force of rubber to guarantee rotation torque power and bent axle axial force.
Adopt the thick 08Al plate of 4mm that the protruding spinning of belt pulley inner side surface is thickened 5.8mm; Being processed into curve then assembles; The synchronous signal tooth spiral is pressed and is formed, and makes vibration damper complement weight saving 1/3rd, when having guaranteed quality of product, has also alleviated weight; The automobile lightweight has also obtained embodiment, has also accomplished the effect of energy-saving and emission-reduction.
