Abstract
The utility model discloses a chain wheel for a particle metallurgy towing vehicle, which is composed of a chain wheel body (1), teeth (2) and a shaft hole (3). The chain wheel is characterized in that a semicircular spline groove (4) is arranged on one side wall of the shaft hole (3), a U-shaped spline groove (5) is arranged on the other side wall of the shaft hole (3), the positions of the semicircular spline groove (4) and the U-shaped spline groove (5) are symmetrical, and six weight reducing circle holes (6) are arranged on the chain wheel body (1) by surrounding the shaft hole (3) a round. The chain wheel for the particle metallurgy towing vehicle is not only molded at one time, but also has the advantages of good wear resistance, corrosion resistance, integrity, easy installation, steady fixing, light specific gravity, high precision and easy mass production, thereby being particularly suitable for the chain wheel of the towing vehicle or replacing the belt pulley transmission of the towing vehicle.
Description
Technical field
The utility model relates to a kind of tractor sprocket wheel, particularly a kind of powder metallurgy tractor sprocket wheel.
Background technique
Since powder metallurgy sintered goods have corrosion resistance, wear resistance, precision height, intensity height, cost of production low, be easy to advantages such as batch process, good integrity, so extensive use, as many component in fields such as the various assemblies of automobile, farm machinery, electrical instrumentation, office machinery, gear etc., be powder metallurgy sintered goods.But through retrieval, at present used sprocket wheel still be a cast article on tractor, its structure by sprocket body, tooth, and axis hole constitute, its axis hole is a circle, its sprocket body is the whole piece body.Its deficiency is it than great, and is insecure with the axle mount, instability.At present, what have on tractor still adopts the belt pulley transmission, by retrieval, does not also see the report that adopts the powder metallurgy sprocket wheel to replace belt pulley.
Summary of the invention
The purpose of this utility model be to provide a kind of proportion little, with the one-time formed powder metallurgy tractor sprocket wheel of the easy held stationary of rotatingshaft.
For reaching above purpose, the technological scheme that the utility model adopted is: this powder metallurgy tractor sprocket wheel, constitute by sprocket body, tooth, axis hole, it is characterized in that on a sidewall of axis hole, establishing semicircle spline, on another sidewall of axis hole, establish " ∪ " shape spline, semicircle spline is symmetrical with the position of " ∪ " shape spline, establishes six loss of weight circular holes around one week of axis hole on sprocket body, to alleviate the proportion of sprocket wheel.The utility model is also implemented by following measure: described axis hole, semicircle spline, " ∪ " shape spline, six loss of weight circular holes, sprocket body, tooth, all adopt the powder metallurgy raw material once sintered in aggregates; The height of described sprocket body is 5.32mm, and tip diameter is 107mm, and root diameter is 96.68mm, shaft hole diameter is 21mm, and the wide of " ∪ " shape spline is 3mm, and semicircle spline radius is 4.5mm, the loss of weight Circularhole diameter is 20mm, its size error≤0.05mm; Described powder metallurgy raw material comprises iron powder AHC100.29%, graphite 0.6-1.0%, copper powder 1-2%, nickel powder 1-2%, zinc powder 0.6-1.0%; Its moulding process comprises batch mixing, compacting, sintering, shaping.
The beneficial effects of the utility model are: not only be once-through, and has an advantage wear-resisting, anti-corrosion, good integrity, the advantage that also have easy installation, fixing-stable, light specific gravity, precision height, is easy to produce in batches is specially adapted to the tractor sprocket wheel or replaces the transmission of tractor belt pulley.
Description of drawings
Fig. 1 is the utility model structure schematic top plan view.
Embodiment
Make the utility model with reference to accompanying drawing 1.This powder metallurgy tractor sprocket wheel, constitute by sprocket body 1, tooth 2, axis hole 3, it is characterized in that on a sidewall of axis hole 3, establishing semicircle spline 4, on another sidewall of axis hole 3, establish " ∪ " shape spline 5, semicircle spline 4 is symmetrical with the position of " ∪ " shape spline 5, on sprocket body 1, establish six loss of weight circular holes 6, to alleviate the proportion of sprocket wheel around 3 one weeks of axis hole.Described axis hole 3, semicircle spline 4, " ∪ " shape spline 5, six loss of weight circular holes 6, sprocket body 1, tooth 2 all adopt the powder metallurgy raw material once sintered in aggregates; The height of described sprocket body 1 is 5.32mm, and tip diameter is 107mm, and root diameter is 96.68mm, axis hole 3 diameters are 21mm, and the wide of " ∪ " shape spline 5 is 3mm, and semicircle spline 4 radiuses are 4.5mm, loss of weight circular hole 6 diameters are 20mm, its size error≤0.05mm; Described powder metallurgy raw material comprises iron powder AHC100.29%, graphite 0.6-1.0%, copper powder 1-2%, nickel powder 1-2%, zinc powder 0.6-1.0%; Its moulding process comprises batch mixing, compacting, sintering, shaping.
Claims (2)
1, a kind of powder metallurgy tractor sprocket wheel, constitute by sprocket body (1), tooth (2), axis hole (3), it is characterized in that on a sidewall of axis hole (3), establishing semicircle spline (4), on another sidewall of axis hole (3), establish " ∪ " shape spline (5), semicircle spline (4) is symmetrical with the position of " ∪ " shape spline (5), goes up in sprocket body (1) and establishes six loss of weight circular holes (6) around (3) one weeks of axis hole.
