Abstract
The invention relates to an integral two-stage sprocket which comprises a large sprocket, a wheel axle and a small sprocket, wherein the large sprocket and the small sprocket are connected and form an integral structure; the integral two-stage sprocket is provided with a center hole; and the center hole is coaxial with the large sprocket, the wheel axle and the small sprocket. At least three through holes are uniformly formed in the side wall of the large sprocket; and at least three grooves are formed in the side of the center hole of the integral two-stage sprocket and are uniformly distributed in the positions close to the center hole on the side wall of the large sprocket. Compared with the prior art, the integral two-stage sprocket formed by processing in a powder metallurgy mode has the characteristics of corrosion resistance, wear resistance, light specific weight, high precision and high strength and the advantages of easiness for mounting, reliability in connection and easiness for machining and batch production. According to the integral two-stage sprocket disclosed by the invention, the production cost is saved and the performances of products are stable and reliable.
Description
Technical field
The present invention relates to the gear technique field, especially a kind of integrated double stage sprocket wheel that processes by the powder metallurgy mode.
Background technique
Existing speed-changing chain normally is fitted together the chain wheel set of two-stage or the above different-diameter of two-stage, and this twin-stage or multi-chain gear wheel generally are split-type structurals, adopts bolt or riveting method to connect between the multi-chain gear wheel and fixes.At present, not only difficulty of processing is larger for above-mentioned twin-stage or multi-chain gear wheel product, and Product Precision is low, and manufacturing efficiency is low, cost is high, product strength is low.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this invention is to provide a kind of integrated double stage sprocket wheel that processes by the powder metallurgy mode.
The objective of the invention is by realizing by the following technical solutions:
The integrated double stage sprocket wheel, described twin-stage sprocket wheel is made of hinge wheel, wheel shaft and minor sprocket, described hinge wheel is connected with minor sprocket by wheel shaft and forms overall structure, and described twin-stage sprocket wheel is provided with center hole, described center hole and described hinge wheel, wheel shaft and minor sprocket coaxial line.
As the preferred technical solution of the present invention, the sidewall of described hinge wheel is laid with at least three through holes.
As the preferred technical solution of the present invention, the limit, hole of described twin-stage sprocket wheel center hole is provided with at least three grooves, and described groove all is laid in the hinge wheel sidewall near the position of center hole.
Judge position beneficial effect of the present invention: with respect to prior art, the present invention adopts the powder metallurgy mode to be processed to form the integrated double stage sprocket wheel, that product has is corrosion-resistant, wear-resisting, light specific gravity, precision is high, intensity is high characteristics, also have advantages of easy installation, connect reliably, be easy to machining and batch production, the present invention has saved cost of production, and product performance are reliable and stable.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is structural representation of the present invention;
Fig. 2 is sectional structure schematic diagram of the present invention.
Embodiment
As depicted in figs. 1 and 2, the integrated double stage sprocket wheel, described twin-stage sprocket wheel is made of hinge wheel 1, wheel shaft 2 and minor sprocket 3, described hinge wheel 1 is connected with minor sprocket 3 by wheel shaft 2 and forms overall structure, described twin-stage sprocket wheel is provided with center hole 4, described center hole 4 and described hinge wheel 1, wheel shaft 2 and minor sprocket 3 coaxial lines.
In the present embodiment, the sidewall of described hinge wheel 1 is laid with three through holes 5, and the limit, hole of described twin-stage sprocket wheel center hole 4 is provided with three grooves 6, and described groove 6 all is laid in large chain 1 and takes turns sidewall near the position of center hole 4.The present invention has that intensity is high, precision is high, easy installation, connect reliable advantage, saves production cost, and product performance are reliable and stable.
