Problems solved by technology

[0002] At present, the sprockets of scraper conveyors used in coal mines have an overall structure of two or three rows of teeth. The manufacturing process is: forging a ring-shaped steel cake, which is manufactured by subsequent machining. It is obviously reduced and the utilization rate of raw materials is low, so it is not suitable for mass production, especially in the process of using the sprocket. Once a sprocket tooth is abnormally broken or worn, the sprocket must be replaced as a whole, resulting in waste of materials again.

Embodiment Construction

[0026] In the figure: 1 right end cover, 2 sprocket tooth block, 3 shaft sleeve, 4 positioning bolt, 5 left end cover, 6 nut;

[0027] Depend on Figure 2-10 As shown, it is composed of right end cover 1, sprocket tooth block 2, shaft sleeve 3, positioning bolt 4 and left end cover 5; right end cover 1 and left end cover 5 have the same structure, and 7 bolt holes are evenly distributed along the circumferential direction; There is a "T" shaped groove on the toothed block 2 corresponding to the "T" shaped boss on the sleeve 3, and there are positioning holes on the toothed block of the sprocket, and the apertures are consistent with those on the left and right end covers, and The distribution score circles have the same diameter. After the above-mentioned 1 piece of left end cover 5, 1 piece of right end cover 1, 1 piece of shaft sleeve 3, 14 pieces of sprocket toothed blocks 2, 7 pieces of positioning bolts 4, and 7 pieces of nut parts are completed, the combined sprocket wh...

Abstract

The invention relates to a coal mine scraper conveyor sprocket and a manufacturing process, in particular to a coal mine scraper conveyor combined sprocket and a manufacturing process. At present, the sprockets of scraper conveyors used in coal mines all have an overall structure of two or three rows of teeth. It is suitable for mass production, especially in the installation and use, when a certain tooth of the sprocket is broken or worn abnormally, the entire sprocket must be replaced, resulting in another waste of materials. The coal mine combined sprocket of the present invention is composed of a left end cover, a right end cover, a sprocket tooth block, a shaft sleeve, a positioning bolt, and a nut, and each component is consistent with the overall sprocket structure after production and assembly. In the present invention, the integral sprocket is improved into a combined type, and the tooth-shaped block of the sprocket is changed from the original machining to direct forging, which simplifies the process, improves the utilization rate of raw materials and reduces the remanufacturing cost.

Description

technical field [0001] The invention relates to the technical field of forging and machining, in particular to a manufacturing process of a combined sprocket for a scraper conveyor used in coal mines. Background technique [0002] At present, the sprockets of scraper conveyors used in coal mines have an overall structure of two or three rows of teeth. The manufacturing process is: forging a ring-shaped steel cake, which is manufactured by subsequent machining. It is obviously reduced and the utilization rate of raw materials is low, so it is not suitable for mass production, especially in the process of using the sprocket. Once a sprocket tooth is abnormally broken or worn, the sprocket must be replaced as a whole, resulting in waste of materials again. . Contents of the invention [0003] The purpose of the present invention is to provide a manufacturing process for the combined sprocket of the scraper conveyor used in coal mines, which can replace the traditional integr...
