Abstract
The utility model discloses the camshaft drive belt pulley of a kind of improvement, including the wheel body being made into integration by powder metallurgical technique, described wheel body center is provided with the axis hole coordinated with camshaft, the end face of described wheel body is provided with the first annular groove coaxial with axis hole, the other end of wheel body is provided with second annular groove coaxial with axis hole, wheel body between described first annular groove and the second annular groove is provided with four lightening holes axially penetrating through wheel body along the distribution of axle centrosymmetry, and the adjacent distance between lightening hole is 20mm.Compared with prior art, the weight being significantly reduced camshaft drive belt pulley by powder metallurgical technique of the present utility model, improve the stability in use of camshaft drive belt pulley simultaneously, extend the service life of camshaft drive belt pulley.
Description
Technical field
This utility model relates to technical field of engines, the camshaft drive belt pulley of a kind of improvement.
Background technology
Electromotor, in running, is that the connection completing between bent axle and camshaft by timing system is driven
Dynamic, the camshaft drive belt pulley in electromotor plays vital in the accurate power of timing wheel train transmits
Effect, camshaft drive belt pulley and crankshaft timing pulley are mainly used in camshaft and the song of minicar engine
On axle, its Main Function is for lighting a fire during engine start, and as driving member, and drive air-conditioning work.
Traditional camshaft drive belt pulley is to be fixed on camshaft by belt wheel by a bolt, but it exists fortune
During Zhuaning, bolt easily slides, and adds the deadweight of belt wheel itself, is easily caused valve and knocks the wind of piston
Danger, causes short problem in service life of belt wheel and occurs.
Summary of the invention
The purpose of this utility model is intended to solve the deficiency of prior art problem, it is provided that the camshaft of a kind of improvement
Timing belt pulley.
For reaching above-mentioned purpose, this utility model is implemented according to techniques below scheme:
A kind of camshaft drive belt pulley of improvement, including the wheel body being made into integration by powder metallurgical technique, described
Wheel body center is provided with the axis hole coordinated with camshaft, and the end face of described wheel body is provided with first coaxial with axis hole
Annular groove, the other end of wheel body is provided with second annular groove coaxial with axis hole, described first annular recessed
Wheel body between groove and the second annular groove is provided with four and axially penetrates through wheel body along the distribution of axle centrosymmetry
Lightening hole, is provided with the strengthening rib strip being connected with wheel body, the thickness of described strengthening rib strip in described second annular groove
Degree is 1.08mm.
As further preferred scheme of the present utility model, described wheel body is provided with pin-and-hole, described pin-and-hole and axis hole
Connection.
As further preferred scheme of the present utility model, the degree of depth of described second annular groove is less than the first ring
The degree of depth of connected in star.
Compared with prior art, of the present utility model camshaft timing is significantly reduced by powder metallurgical technique
The weight of belt wheel, the addition of strengthening rib strip simultaneously makes the intensity of wheel body more greatly, improves camshaft drive belt pulley
Stability in use, extend the service life of camshaft drive belt pulley.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by specific embodiment, in this utility model
Illustrative examples and explanation be used for explaining this utility model, but be not intended as limit of the present utility model
Fixed.
As shown in Figure 1 and Figure 2, the camshaft drive belt pulley of a kind of improvement of the present embodiment, including by powder smelting
The wheel body 1 that gold process is made into integration, described wheel body 1 center is provided with the axis hole 2 coordinated with camshaft, described takes turns
The end face of body 1 is provided with the first annular groove 5 coaxial with axis hole, and the other end of wheel body 1 is provided with and axis hole
The second coaxial annular groove 6, on the wheel body 1 between described first annular groove 5 and the second annular groove 6
It is provided with four lightening holes 4 axially penetrating through wheel body 1 along the distribution of axle centrosymmetry, described second annular groove 6
Inside being provided with the strengthening rib strip 7 being connected with wheel body 1, the thickness of described strengthening rib strip 7 is 1.08mm, described
The degree of depth of second ring groove 6 is less than the degree of depth of first annular groove 5, it is possible to keeping the overall strong of wheel body 1
Alleviate weight while degree as far as possible.
For slip after preventing wheel body 1 to be installed on camshaft, described wheel body 1 is provided with pin-and-hole 3, described pin-and-hole
3 connect with axis hole 2, improve the stability in use of camshaft drive belt pulley.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, every new according to this practicality
The technology deformation that the technical scheme of type is made, within each falling within protection domain of the present utility model.
