Description
Technical field
The utility model is related to a kind of powder metallurgy chain wheel.
Background technology
The transmission of bent axle and camshaft typically uses chain drive, the transmission efficiency of chain drive, reliability and durability
It is higher
But the cost of chain transmission system is higher than belt transmission.It is reduces cost, simplifies structure, the use installed on bent axle
Powder metallurgy being used with the sprocket wheel of chain drive, the dimensional accuracy of powder metallurgy is high, low cost of manufacture, but its intensity is relatively low more.
Therefore it is badly in need of a kind of intensity of design good, the sprocket wheel of good combination property.
Utility model content
The utility model provides a kind of powder metallurgy chain wheel.
In order to solve the above problems, the technical solution adopted in the present invention is a kind of such, powder metallurgy chain wheel, the powder

Outer circumferential walls are provided with sprocket, the upper surface distance of sprocket matrix top surface to sprocket and the lower surface of sprocket matrix bottom surface to sprocket
Distance is 5：1, the thickness of sprocket and the ratio of sprocket matrix thickness are 1:2, groove, groove bottom land and chain are provided between adjacent sprocket
Tooth root circle is tangent, and axis hole is provided with the middle part of sprocket wheel matrix, and sprocket wheel matrix two ends outer rim and axis hole two ends aperture are equipped with 30 ° and fall
Angle.
Preferably, the reference diameter of described sprocket is 46mm, and tip diameter is 43mm, and root diameter is
34mm。
Preferably, the described sprocket number of teeth is 18.
Preferably, width of the width of the tooth root of sprocket more than crown.
Beneficial effect：The utility model can be effectively improved when sprocket wheel accelerates while ensure that the intensity of sprocket wheel
Response, in addition, sprocket wheel matrix two ends outer rim and axis hole two ends aperture are equipped with 30 ° of chamferings, are easy to assemble, reduce stress collection
In.
