Description
Technical field
The present invention relates to a kind of belt pulley of automobile engine technical field, more particularly to a kind of dustproof automotive idle pulley.
Background technology
With the fast development of machinery industry, requirement to mechanical basic part with regard to more and more higher, based on one of part
Bearing must also is fulfilled for the requirement of industry development, and bearing increasingly pursues " high accuracy, high rotating speed, low torque, long-life, system
Change "；Wherein systematization（The intensity of auxiliary equipment）It is increasingly faster in latest developments, it be embodied in product whole design,
In the links such as processing, buying, assembling, management, especially inside automotive engine applications, idle pulley starts with belt in automobile
Long-term rotation inside cabin, the non-tight structure due to cabin and negative pressure meeting caused by air flow in being travelled due to vehicle
So that the dust and impurity in the external world are brought into enging cabin, idle pulley is easier to be entered by dust and impurity outside due to exposed
Attachment is invaded, into idle pulley Bearing inner, causes bearing element part surface damage, causes bearing clearance to become big, the support to belt
Effect becomes unstable, ultimately results in engine power output and is deteriorated, therefore the present invention designs a kind of dust-proof dust-removing automobile idle pulley, carries
For three-level is dust-proof and the effect of dedusting, pass through the cooperation of dust cap and dedusting groove and idle pulley housing so that into the ash of idle pulley
Dirt is discharged or accumulated in the storage dirt portion of dust cap, is protected the life-span of bearing, is easy to dedusting, there is provided idle pulley is preferably driven, and is subtracted
The fuel oil loss of few automobile, preferably realizes the conversion of energy, is finally reached the effect of energy-saving and emission-reduction.
The content of the invention

Symmetrically arranged housing flange and symmetrically arranged dome platform, the dome platform are provided with dedusting with the housing flange junction
Groove, the dust cap include dust cap flange, store up dirt portion and joint portion, the diameter of the dust cap flange are more than the dome platform
External diameter, the diameter of the dust cap flange is less than the diameter of the housing flange.
Thus, the dust cap coats the dome platform, and between leave gap, the width in the gap stayed is less than described
The half of the width of dedusting groove, first order dust-proof dust-removing is formed, when idle pulley is during running at high speed, extraneous dust can connect first
The housing and the housing flange are touched, is then gradually accumulated in the dedusting groove, due to the centrifugal motion of high speed, dust
The lateral surface of the housing flange can be gradually gathered in, the medial surface of the housing flange is coated by the dust cap flange,
And the medial surface of the housing flange and the dome platform are affixed, the two level that the cladding of the dust cap flange forms idle pulley is prevented
Dirt.
It is described to unload dirt cambered surface and the dust cap turns over as a preference of the present invention, the joint portion, which is provided with, unloads dirt cambered surface
While connected by the storage dirt portion.
Thus, the angle of inclination for unloading dirt cambered surface is 45 degree, because the dust cap is in the idle pulley motion process
Do not moved with the motion of idle pulley, thus through two level proofing dust and protecting dust be dust inside dust cap can with from
The heart is moved, and the dust removal unit, 45 degree of works that can either ensure not influenceing bearing are eventually entered into by unloading dirt cambered surface described in 45 degree
Make, it is also possible that dust preferably enters the storage dirt portion, improve life-span and the efficiency of bearing working.
As a preference of the present invention, the dedusting groove there are medial surface and lateral surface, the medial surface with it is described dust-proof
2 ~ 3 millimeters of gap is provided between lid flange, two level is formed while can ensure not interfering with one another with the use of under and is prevented
Dirt, the inclination angle of the lateral surface is α, and α angles are preferably 10 degree, and in idle pulley rotation process, the dust into the dedusting groove exists
Idle pulley preferably is skidded off along lateral surface in the presence of centrifugal motion, forms the preliminary dust-proof and dedusting of idle pulley.
As a preference of the present invention, the medial surface is connected with the lateral surface by deep-slotted chip breaker.
Thus, the deep-slotted chip breaker can be used for grade dirt and dedusting, and the mellow and full transition of the lateral surface is preferably beneficial to remove
Dirt.
As a preference of the present invention, the outer rim of two housing flange is in the same face of cylinder.
As a preference of the present invention, the dust cap is symmetrical arranged.
As a preference of the present invention, also including bearing, the bearing is detachably connected with the housing by hole with back-up ring.
As a preference of the present invention, the dome number of units amount is 2, and the width of symmetrically arranged left dome platform is more than the right side
The width of dome platform, it is easy to the installation and fixation of the bearing while fool-proof design.
The invention has the advantages that：
The present invention designs a kind of dustproof automotive idle pulley, there is provided three-level is dust-proof and the effect of dedusting, by dust cap and dedusting groove with
And the cooperation of idle pulley housing so that into idle pulley dust discharge or accumulate and in the storage dirt portion of dust cap, protect longevity of bearing
Life, is easy to dedusting, there is provided idle pulley is preferably driven, and is reduced the fuel oil loss of automobile, is preferably realized the conversion of energy, finally reach
To the effect of energy-saving and emission-reduction.
Below by drawings and examples, technical scheme is described in further detail.
