Embodiment Construction

[0025] Such as Figure 1 to Figure 3 As shown, the present invention takes the mechanical transmission sprocket as an example, selects trace elements as a whole to make the strength of the sprocket uniform, improves the rigidity, wear resistance and corrosion resistance of the sprocket, and feeds the ingredients into the precision molding die during the manufacturing process , the sprocket blank is formed by upsetting extrusion, and the density of the sprocket blank is greater than or equal to 7.5Mg / m 3 , through sintering, and then quickly cooled to 300 degrees Celsius with air-cooled blast, and then put the sintered sprocket into the furnace for slow cooling, so that the inside becomes dense, the hardness distribution is uniform, the strength is high, and it is not easy to break, and hobbing is used processing, reducing costs, shortening the processing cycle, and using phenolic laminated cloth to enhance the wear resistance and corrosion resistance of the sprocket.

Abstract

The invention discloses a mechanically actuated chain wheel material, and a manufacturing method thereof. The mechanically actuated chain wheel material comprises following ingredients: 0.2 to 0.35 part of C, 0.35 to 0.55 part of Si, 0.6 to 0.9 part of Mn, Ni<=0.25 part, Cr<=0.20 part, S<=0.02 part, Al<=0.05 part, P<=0.03 part, Cu<=0.40 part, Mo<=0.05 part, V<=0.03 part, Nb<=0.01 part, Ti<=0.01 part, and the balance Fe. The manufacturing method comprises steps of (a) drawing; (b) material preparaing; (c) compacting and shaping; (d) sintering; (e) cooling; (f) rough machining; (g) gear hobbing processing; and (h) heat processing. According to the manufacturing method, the ingredients above are selected so as to obtain chain wheels with uniform strength. In preparation processes, the ingredients are delivered into a mould; a chain wheel blank material is obtained via upsetting extruding, and is subjected to sintering and cooling, so that the internal part of the mechanically actuated chain wheel material is compact, is high in strength, and is not easily fractured; gear hobbing processing is adopted, so that cost is reduced, and processing cycle is shortened; and phenolic aldehyde cloth base laminates are used, so that wear resistance and corrosion resistance of the chain wheels are increased.

Description

technical field [0001] The invention relates to a mechanical transmission sprocket material and a manufacturing method. Background technique [0002] The sprocket is an important part of the chain transmission. The sprocket is a wheel with cog-type buckle teeth, which is used to mesh with the pitch-accurate blocks on the link chain or the cable, or it is a solid or spoked gear. (Roller) chain meshes to transmit motion, and is widely used in mechanical transmission in chemical industry, textile machinery, food processing, instrumentation, petroleum and other industries. Generally, the sprocket is composed of three parts: the ring gear, the hub and the spokes. Generally, the chain drive is composed of a driving sprocket mounted on a parallel shaft, a driven sprocket and a chain wound on the sprocket. Rotate and transmit motion and power, because the chain transmission belongs to the meshing transmission with intermediate flexible parts, accurate transmission can be obtained,...
