Description
Technical field
The present invention relates to belt pulley of automobile engine technical field more particularly to a kind of anti-dropout idle pulley assemblies.
Background technology
With the fast development of machinery industry, the requirement to mechanical basic part with regard to higher and higher, based on one of part
Bearing also must satisfy the requirement of industry development, and bearing increasingly pursues " high-precision, high rotating speed, low torque, long-life, system
Change "；Wherein systematization（The intensity of auxiliary equipment）Be getting faster in latest developments, it be embodied in product it is entire design,
In the links such as processing, buying, assembling, management, not only during assembly and use, it is also required to more in transportational process
Safe and standardization, in the prior art idle pulley be transported by exactly by the idle pulley assembled carry out vanning transport equipment cart
Between, it is assembled by worker or machinery, usual idle pulley, which is assembled on engine face, needs re-generating engine panel side addition pad
Piece is to protect the service life of idle pulley, and often worker or machinery are dosed, and more procedures cause manpower and cost
Waste, and efficiency of assembling is also low, and if common gasket is transported together with idle pulley, gasket or washer can transport
It is fallen in journey, it is very not convenient to need manpower to carry out mating installation again.
Invention content
The present invention devises a kind of anti-dropout idle pulley assembly to solve the above technical problem, including connects successively from inside to outside
Axle sleeve, bearing and the wheel body connect, the axle sleeve outside is at least provided with sequentially connected first platform, the second platform and third
Platform, the top of the bearing are abutted with first platform side, and the diameter of first platform is more than second platform
Diameter, the diameter of second platform is more than the diameter of the third platform, and the third mesa base is socketed with guard member,
The top of the guard member contradicts with the bearing inner race and connects.
Slight interference coordinates between the guard member side and the axle sleeve as a result, and the guard member is sleeved on the axle sleeve bottom
On the third platform at end, there is gap between the guard member inner flange and the third platform, the protection can be prevented
Part is locked in the course of work after mounting, and the top of the guard member abuts the inner ring of the bearing, can be for the axis
The location and installation held is for fixing while not influencing the rotation of the bearing outer ring, described so in transportational process
Guard member can play the transport being fixed together with the idle pulley assembly and avoid the bearing and the guard member from lazy
It is fallen on wheel assembly, in assembling process, the guard member carries out the assembly of engine, Neng Gouqi together with the idle pulley assembly
To the protection and rubbing action of washer or gasket, the step of simplifying assembly, convenient for improving production efficiency.
As a preference of the present invention, the guard member includes base ring and flange, the base ring includes outer and inner flange, institute
It states flange and is arranged between the outer of the base ring, the inner flange and the third platform and be provided with gap, in the flange
Side is connect with the lateral surface of the third platform, and the inner ring of the top of the flange and the bearing, which contradicts, to be connected.
The guard member realizes itself and the axis by the interference fit between the flange and the third platform as a result,
Connection between set, there are gaps between the inner flange and the third platform, can prevent the work of the guard member
In the process locked to influence the operation of entire idle pulley.
As a preference of the present invention, the wheel body is connect with the outer ring of the bearing.
The wheel body inner ring is provided with the protrusion with the blocking bearing outer ring far from the guard member side as a result, leans on
The side of the nearly guard member is not provided with protrusion, and the guard member resists one section of the bearing inner race, the bearing inner race
The other end resisted by first platform, to realize the fixation of bearing inner race, one section of the bearing outer ring with it is described
The protrusion of wheel body inner ring resists, and in transportational process, three points are to realize the positioning of the bearing, and the bearing inner race
Fixation have no effect on the rotation of the bearing outer ring.
As a preference of the present invention, the bearing inner race is connect with second contact with platform, the guard member with it is described
Third platform interference connects, and the thickness of flange is more than the bearing inner race thickness.
It is that the flange outer sides diameter is identical as the bearing inner race outside diameter as a result, the flange and the third
Platform and the bearing inner race surround an annular space, so ensure that the flange or even the entire guard member are transporting
The support force of the fixed bearing is provided in the process, the guarantor is interference fitted on the third platform of the sleeve diameter minimum
Guard reduces the arm of force so that frictional force and support force on the same line, have not disperseed the size of support force, identical
The bearing can be more preferably supported in the case of frictional force in transit.
As a preference of the present invention, the difference in height of first platform and second platform is more than the bearing inner race
Thickness.
Thereby it is ensured that first platform can resist the bearing inner race completely, forms bearing inner race and preferably position.
As a preference of the present invention, the base ring is connect with the flange integral type.
As a preference of the present invention, further include dustproof cover, the inner ring and described first that the dustproof cover passes through the bearing
Platform limit connection.
The dustproof cover inner cover and outer cover are by chamfered transition as a result, and on depth of section, inner cover height is high less than outer cover
Degree, inner cover are arranged on the internal bearing cover and below first platform, and inclined-plane covers in the entire bearing with outer cover
The outermost of the wheel body of half to 2/3rds, outer cover is provided with right angle dust board, towards the wheel body direction,
Realize the package of the entire bearing and dust-proof, the bearing outer ring is wrapped up by the wheel body, realizes fixed and dust-break.
As a preference of the present invention, the axle sleeve inner ring is ladder-like.
The invention has the advantages that：
The present invention designs a kind of anti-dropout idle pulley assembly, and guard member designs concave hole and is interference fitted with axle sleeve so that guard member
It is pressed on the inner ring of bearing and realizes the fixation of bearing inner race and do not influence the rotation of bearing outer ring, and prevented in transportational process
Guard member is fallen, and in assembling process, the process that can reduce by one of assembly washer gives prodigious transport and assembly just
Profit improves production efficiency.
