Abstract
The utility model discloses a light weight, high strength idler, including integrative fashioned wheel axle base, outer wheel ring and the connecting plate of forging, the connecting plate is whole to be the ring form and evenly to be equipped with a plurality of through -holes, and its outer peripheral face links to each other with outer wheel ring is inboard, and the inner peripheral surface links to each other with the wheel axle base outside, the thickness of connecting plate be outer wheel ring 12~23, wheel axle base 14~13, the connecting plate outer peripheral face is equipped with the rounding off face with inboard combination department of outer wheel ring, the connecting plate inner peripheral surface is equipped with transition step face with wheel axle base outside combination department. The utility model discloses a structure and the size of wheel axle base, outer wheel ring and connecting plate are optimized to the equitable through -hole that sets up, can reduce its quality under the circumstances that forbids idler intensity.
Description
Technical field
The utility model relates to motor vehicle components technical field, relates to engine component, particularly to a kind of high-strength light idle pulley.
Background technology
Idle pulley is conventional automobile engine assembly, idle pulley High Rotation Speed during use, therefore higher to its requirement of strength, therefore the current commonly used forging molding of idle pulley, but, along with the propelling of energy-saving and emission-reduction, locomotive lightweight is to become a kind of trend, it is therefore desirable to idler mechanism is improved, in the hope of reaching the effect of lightweight, high intensity.
Summary of the invention
In view of this, the utility model provides a kind of high-strength light idle pulley.
A kind of high-strength light idle pulley, including the one axle block of forging molding, outer rim and connecting plate, described connecting plate is overall in circular and be uniformly provided with multiple through hole, and its outer peripheral face is connected with inside outer rim, and inner peripheral surface is connected with outside axle block；The thickness of described connecting plate is the 1/2～2/3 of outer rim, the 1/4～1/3 of axle block；Inside described connecting plate outer peripheral face and outer rim, junction is provided with junction outside rounding off face, described connecting plate inner peripheral surface and axle block and is provided with transition bench terrace.
Further, described through hole is ellipsoid shape, and its number is five, is evenly distributed on the same circumference of connecting plate.
Further, the 1/4 of each through hole a length of place periphery, width is the 4/5 of connecting plate.
Further, being provided with axle installing hole in the middle part of described axle block, its lower end is concordant with connecting plate, and upper end upwardly extends.
The beneficial effects of the utility model are:
The utility model, by reasonably arranging through hole, optimizes axle block, outer rim and the structure of connecting plate and size, can reduce its quality in the case of not allowing idle pulley intensity.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is the utility model high-strength light idle pulley structure chart.
Detailed description of the invention
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, the high-strength light idle pulley of the present embodiment, including the one axle block 6 of forging molding, outer rim 1 and connecting plate 3, described connecting plate 3 entirety is circular and is uniformly provided with multiple through hole 4, its outer peripheral face is connected inside outer rim 1, and inner peripheral surface is connected outside axle block 6；Thickness is outer rim 1 1/2～the 2/3 of described connecting plate 3, the 1/4～1/3 of axle block 6；Inside described connecting plate 3 outer peripheral face and outer rim 1, junction is provided with junction outside rounding off face 2, described connecting plate 3 inner peripheral surface and axle block 6 and is provided with transition bench terrace 5.
In the present embodiment, described through hole 4 is in ellipsoid shape, and its number is five, is evenly distributed on the same circumference of connecting plate 3；The 1/4 of each through hole 4 a length of place periphery, width is the 4/5 of connecting plate 3, is provided with axle installing hole 7 in the middle part of described axle block 6, and its lower end is concordant with connecting plate 3, and upper end upwardly extends.
In the utility model, axle block 6 wall thickness is about 15-17mm, a diameter of 69mm of axle installing hole 7, and connecting plate 3 width is about 40-43mm, and outer rim 1 thickness is about 13mm.
The utility model, by reasonably arranging through hole, optimizes axle block, outer rim and the structure of connecting plate and size, can reduce its quality in the case of not allowing idle pulley intensity.
Finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described by referring to preferred embodiment of the present utility model, but it will be understood by those within the art that, in the form and details it can be made various change, the spirit and scope of the present utility model limited without departing from appended claims.
