Abstract
The utility model provides an automobile engine timing bent shaft damping belt wheel which comprises a belt wheel. A hot rolled pickling plate with a thickness of 4 millimeters is stretched to a barrel shape and then is molded into the belt wheel by means of flow forming. Signal teeth are arranged at the edge of the belt wheel and a mounting hole is arranged in the middle of the belt wheel. A silicone oil shock absorber is nested inside a mold cavity of the belt wheel. A tooth space and the signal teeth are thickened by means of the flow forming. The belt wheel which is made of the hot rolled pickling plate with the thickness of 4 millimeters by means of the flow forming achieves a good quality and guarantees the transmission torque of the engine. Due to the use of the hot rolled plate, the original organization structure of the belt wheel is changed and the production cost is reduced. Due to the fact that the tooth space and the signal teeth are thickened by means of the flow forming, good product quality and high product intensity are achieved. Meanwhile, material cost is not increased because the thickening by means of the flow forming is based on the flow forming of material self.
Description
Technical field
The component of the utility model motor car engine specifically are motor car engine shock-proof crank pulleys in correct time.
Background technique
At present, more and more belt pulleys all are plate system spinning belt pulleys in the motor car engine, and this type belt pulley has light weight, cheap; Still do not reduce complete vehicle weight; Realize one of automobile lightweight approach, and can reduce cost, improve car load and competition of the same trade.
But crank pulley but still adopts the ironcasting belt pulley mostly, and this is because this belt pulley is being controlled fuel injection as key component in BBG, thereby whether controlling toxic emission up to standard.Even have minority producer to adopt the spun type crank pulley, but, make silicone oil vibration damper and belt pulley separate assembling usually because the spun type belt pulley is thinner, can make the bent axle lengthening like this, sacrificed transfer of torque.
The thickness of signal teeth wherein is 3.5mm, occur in use insufficient strength and signal a little less than.
Summary of the invention
The utility model is in order to guarantee the transfer of torque of motor, the special motor car engine shock-proof crank pulley in correct time that proposes.
The technological scheme of the utility model does for this reason; Motor car engine shock-proof crank pulley in correct time; Comprise pulley body, it is characterized in that: described belt pulley is drawn into tubbiness rotary press modelling again with the thick hot rolling acid-cleaning plate of 4mm, and is provided with signal teeth at the pulley rim place; The centre of belt pulley is provided with mounting hole, the embedded silicone oil vibration damper that is with of the die cavity of belt pulley.
To being in improvement of such scheme: the thickness of said teeth groove is 5.5 ~ 6mm, thickens through spinning.
Improvement to such scheme is: the thickness of signal teeth is 5mm, thickens through spinning.
Beneficial effect:
The utility model uses the thick hot rolling acid-cleaning plate spinning belt pulley of 4mm to guarantee quality; Also guaranteed the transfer of torque of motor; Use hot rolled plate not only to change the Organizational Structure of former belt pulley, and cost of production is reduced greatly, the spinning of teeth groove and signal teeth thickens the intensity that the quality that has not only ensured product has also guaranteed product; Spinning thickens and utilizes the spinning of material own simultaneously, does not increase cost of material.

Embodiment
The utility model is like Fig. 1, shown in 2.
In shown in Figure 1; Example product is a revolving meber, and 8 many V of groove formula shock-proof crank in correct time crank pulleys 1, described belt pulley 1 are to be drawn into tubbiness rotary press modelling again with the thick hot rolling acid-cleaning plate of 4mm; And be provided with signal teeth 3 in belt pulley 1 edge; The centre of belt pulley 1 is provided with mounting hole 5, the embedded silicone oil vibration damper 5 that is with of the die cavity of belt pulley 1
The thickness of said teeth groove 2 is 5.5 ~ 6mm, thickens through spinning.
The thickness of signal teeth 3 is 5mm, thickens through spinning.
