In order to solve the above technical problems, the utility model is adopted the following technical scheme that：
A kind of pressing type belt pulley, the pressing type belt pulley includes：Cast iron inner ring, cast iron outer ring, vulcanization rubber ring；Institute
Vulcanization rubber ring is stated to be arranged between cast iron inner ring, cast iron outer ring.
As a kind of preferred scheme of the present utility model, projection is provided with the outside of the cast iron inner ring；Set on the inside of cast iron outer ring
It is fluted, with the male cooperation on the outside of cast iron inner ring.
The inner ring (cast iron), outer ring (cast iron) and vulcanization rubber press-fit the belt pulley integrally changed, and constitute the belt
Wheel is using process is press-fited, and technological parameter adjustability is good, and technological parameter is stable；
The cast iron inner ring, cast iron outer ring can be made using techniques such as castings, cast iron Internal and external cycle product performance ginseng
Number is stable, casting technique is ripe, producing efficiency is high, cost is relatively low.
The cast iron Internal and external cycle is not required to be placed in sulfurizing mould, it is not necessary to manufacture huge belt pulley sulfurizing mould, vulcanization
Before be not required to carry out cast iron Internal and external cycle complicated pretreatment procedure：It is main evaded ramming, cleaning, phosphatization, baking, apply primer,
The processes such as painting face glue.Directly reduce manufacturing process cost.
The cast iron Internal and external cycle is assembled with rubber using interference mode, is pressed into described rubber ring.The elastomeric element is
Elastomeric material, its vulcanization parameters are stable, and sizing compound formula adjustability is more.Rubber part sulfurizing mould is simple in construction, sizing material mistake
Journey management and control is simplified.
The beneficial effects of the utility model are：The utility model proposes pressing type belt pulley, by the skin of sulfuration type
Both belt wheel, belt pulley of pressing type are combined together, and the engine system torque axis that not only can significantly decay output is turned round
Rotational oscillation is moved, and ensures the transport of engine power, power transmission ride comfort, lifting service life of aeroengine；Rubber part
The drag angle of generation can improve significantly to two principal oscillation mode of Bounce and Pitch of power assembly, so as to
Booming sound in vehicle NVH performances, reduction driver's cabin is improved very well.
Specific beneficial effect of the present utility model is：
1st, the complex optimization to power assembly system is avoided.
2nd, by the way that different cars can be met to rubber structure, rubber hardness, cast iron inner ring, the change of cast iron outer ring mass parameter
The requirement of type, platform application is wide.
3rd, not only decayed the vibration of engine crankshaft, and improves the ride comfort of the power transmission of power assembly, together
When be also beneficial to power assembly bent axle service life extension.
4th, simple in construction, technique is simple, and performance is easily controllable, with low cost.
5th, good airproof performance, circular, using rubber part individual curing, the rigidity of product and damping are easy to by sizing compound formula
Carry out management and control；Using the assembling mode of pressing type, contribute to lifting production technology ability and process control capabilities.
6th, only pressing type belt wheel assembly part progress intrinsic frequency, the detection of moment of torsion, fatigue endurance test need to can just be pressed
Whether dress formula belt pulley meets the requirement of power assembly.
