Description
Technical field
The utility model is related to automobile transmission part fields, and in particular to metal plate ratch hub crankshaft vibration damping belt pulley.
Background technology
With the development of auto industry, China's energy has become the international second largest consumer nation, save energy consumption at
For the act of certainty.The damper pulley of existing market connects belt pulley by rubber ring by wheel hub and is assembled.In general,
Torque is periodically applied on the bent axle of vehicle motor, therefore the vibrations that twist.Cylinder body there are four gasoline engine is general, four
A cylinder body ignition order is different, generates twisting vibration, causes bent axle amplitude excessive, generates energy, damper pulley vibration consumption
Energy can reduce crankshaft vibration, protect engine crankshaft.In order to cater to the fuel economy of vehicle and required lightweight is wanted
It asks, is also got higher therewith for reducing the requirement of weight of engine or damper pulley.The cast iron quality of the prior art subtracts
Although shaking belt pulley has enough intensity and durability, it has the shortcomings that weight is big, the expensive disadvantage of the prices of raw materials.
In addition, in order to make damper pulley lightweight, the wheel hub made of steel plate, but such belt pulley is enough to bear from bent axle
The sharp pounding of transmission and the intensity for bearing torque.And wheel hub is typically all to be processed by HT250 gray cast iron materials, casting is universal
There are stomata, shrinkage porosite, influence the defects of intensity, product high rejection rate；It is machined again after wheel hub casting, consumable material is more, product
Surface is unsightly.
Utility model content
The purpose of the utility model is to overcome defect mentioned above and deficiencies, and provide metal plate ratch hub bent axle vibration damping skin
Belt wheel.
The utility model realizes that the technical solution that its purpose uses is as follows.
Metal plate ratch hub crankshaft vibration damping belt pulley, including the wheel hub of coaxial arrangement, spoke, belt pulley；The wheel hub is in cylinder
Shape, axial middle part offer hub centre hole；The spoke is wholely set with wheel hub；For spoke in annular shape, spoke inside is solid
Dingan County is loaded on wheel hub one end；The belt pulley is sheathed on outside spoke, and rubber ring is folded between wheel hub and belt pulley.
The spoke is angularly opened up there are three waist-shaped hole.
The wheel hub is provided with stepped hole close to spoke one end；The diameter of the stepped hole is more than the straight of hub centre hole
Diameter.
The spoke, belt pulley gap setting form the accommodating chamber of accommodating rubber ring, and accommodating chamber is provided with anti-decylization；It accommodates
Both sides inner wall synchronization of the chamber at anti-decylization is inwardly or outwardly protruded.
The one end of the wheel hub far from spoke is equipped with oil sealing.
It is provided with the V-ribbed belt of 6PK on the right side of the belt pulley, left side is provided with the belt wheel outward flange outwardly protruded, outside belt wheel
The outer diameter of flange is more than the outer diameter of V-ribbed belt；The belt wheel outward flange offers balance hole.
Metal plate ratch hub crankshaft vibration damping belt pulley, wheel hub, belt pulley are centrosymmetric structure, product after wheel hub spinning
Intensity greatly improves, and is conducive to improve the belt pulley service life, product qualification rate is high.Vibration damping belt-pulley hub uses metal plate monoblock type knot
Structure, product size can obtain degree of precision, and belt service life extends.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the front view of the utility model：
In figure：Wheel hub 1, hub centre hole 1a, stepped hole 1b, spoke 2, waist-shaped hole 2a, rubber ring 3, anti-decylization 4, belt
Wheel 5, belt wheel outward flange 5a, balance hole 5b.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
Metal plate ratch hub crankshaft vibration damping belt pulley, including the wheel hub 1 of coaxial arrangement, spoke 2, belt pulley 5；The wheel hub 1 is in
Cylindrical shape, axial middle part offer hub centre hole 1a, for engine shaft assembly positioning；The spoke 2 and 1 one of wheel hub
Setting；Spoke 2 is fixedly installed in 1 one end of wheel hub in annular shape, 2 inside of spoke；The belt pulley 5 is sheathed on outside spoke 2, and
Rubber ring 3 is folded between wheel hub 1 and belt pulley 5.
The spoke 2 is angularly opened up reduces the energy consumption of product there are three waist-shaped hole 2a for mitigating weight.
The wheel hub 1 is provided with stepped hole 1b close to 2 one end of spoke；The diameter of the stepped hole 1b is more than hub centre hole
The diameter of 1a.Stepped hole 1b is for installing gasket and bolt.
The spoke 2,5 gap setting of belt pulley form the accommodating chamber of accommodating rubber ring 3, and accommodating chamber is provided with anti-decylization 4；
Both sides inner wall synchronization of the accommodating chamber at anti-decylization 4 is inwardly or outwardly protruded.The setting of anti-decylization 4 ensure that rubber ring 3 is being pressed
It is not shifted after entering accommodating chamber, prevents spoke 2, the sliding dislocation of belt pulley 5, influence damper pulley assembly precision.
The one end of the wheel hub 1 far from spoke 2 is equipped with oil sealing, prevents bent axle oil leak.
The belt wheel outward flange 5a offers balance hole 5b.5 right side of the belt pulley is provided with the V-ribbed belt of 6PK, left side
It is provided with the belt wheel outward flange 5a outwardly protruded, the outer diameter of belt wheel outward flange 5a is more than the outer diameter of V-ribbed belt, is put down so that product bores
Weigh hole 5b；
1 material of wheel hub is hot continuous-milling steel plate.Wheel hub 1, belt pulley 5 are centrosymmetric structure, product after 1 spinning of wheel hub
Intensity greatly improves, and is conducive to improve the belt pulley service life, product qualification rate is high.
Vibration damping belt-pulley hub uses metal plate monolithic construction, and product size can obtain degree of precision, belt service life
Extend；Production cost reduction greatly reduces cost input without precision cutting process lathe simultaneously, and stock utilization is big
It is big to improve, 25% cost of raw material can be reduced.
The utility model is illustrated according to embodiment, and under the premise of not departing from present principles, the present apparatus can also be made
Go out several modifications and improvements.It should be pointed out that all technical solutions obtained using modes such as equivalent substitution or equivalent transformations, are fallen
