Abstract
The utility model relates to a kind of scraper conveyor for coal mines sprocket wheel, specifically a kind of scraper conveyor for coal mines Combined chain wheel.At present, scraper conveyor for coal mines sprocket wheel is the integral structure of two, three toothrows, its manufacturing process is: forge an annular steel cake, form through follow-up machinework manufacture, production efficiency and utilization rate of raw materials are all low, are not suitable for batch manufacturing, especially in installation is used, while there are improper fracture or wearing and tearing in sprocket wheel tooth, just must be by sprocket wheel integral replacing, cause the waste again of material.Colliery of the present utility model is with Combined chain wheel by left end cap, right end cap, sprocket tooth form piece, axle sleeve, dowel bolt, and nut forms, and it is rear consistent with overall chain sprocket structure that each parts have been produced assembling.In the utility model, overall sprocket wheel is improved to compound type, and sprocket tooth form piece changes direct forging into by original machinework and formed, work simplification and improved utilization rate of raw materials and lowered manufacturing cost again.
Description
Technical field
The utility model relates to a kind of scraper conveyor for coal mines sprocket wheel, specifically a kind of scraper conveyor for coal mines Combined chain wheel.
Background technology
At present, scraper conveyor for coal mines sprocket wheel is the integral structure of two, three toothrows, its manufacturing process is: forge an annular steel cake, form, in tooth Profile Machining stage procedure complexity through follow-up machinework manufacture, the obvious attenuating of production efficiency and utilization rate of raw materials are low, be not suitable for batch manufacturing, especially in sprocket wheel use procedure, once the problems such as improper fracture or wearing and tearing occur certain sprocket, just must be by sprocket wheel integral replacing, cause the waste again of material.
Summary of the invention
The purpose of this utility model is to provide a kind of scraper conveyor for coal mines Combined chain wheel, replaces traditional scraper conveyor for coal mines entirety sprocket wheel.
The technical scheme that the utility model adopts is: scraper conveyor for coal mines Combined chain wheel is made up of right end cap, sprocket tooth form piece, dowel bolt, axle sleeve and left end cap; Right end cap is consistent with left end cap structure, along the circumferential direction raw uniform 7 bolts hole; On sprocket tooth form piece, have "T"-shaped groove corresponding with the "T"-shaped boss on axle sleeve, on sprocket tooth form piece, have knock hole, aperture is consistent with the aperture on left end cap, right end cap, and institute distributes to such an extent that reference diameter is consistent.Combined chain wheel is after above-mentioned 1 left end cap, 1 right end cap, 1 axle sleeve, 14 sprocket tooth form pieces, 7 dowel bolts, 7 nut parts have been produced, along the circumferential direction divide two sockets to enter the "T"-shaped boss of axle sleeve the "T"-shaped groove of sprocket tooth form piece, play the effect of calibration and location.Left end cap, right end cap are enclosed within respectively to axle sleeve two ends, by the knock hole centering on the bolt hole on end cap and sprocket tooth form piece.Dowel bolt is inserted to left end cap, passes two row sprocket tooth form piece knock holees, pass from right end cap, fix with nut, Combined chain wheel has been assembled, and its structure is consistent with overall chain sprocket structure.
The beneficial effects of the utility model are: 1. the direct forging molding of profile of tooth, has solved production efficiency low, the problem not can manufacture.Simplify production process, improved production efficiency and utilization rate of raw materials.2. sprocket tooth form piece forges later half finish turning, finish turning, and actv. has prevented the product size wild effect of bringing because of hammer scale etc., the conformability of sprocket tooth form piece size while having ensured batch manufacturing.Effectively control product design.3., when inefficacy sprocket wheel is manufactured again, sprocket tooth form piece is changed convenient, and lopsided wear sprocket tooth form piece can reuse by Rotate 180 °.Greatly reduce the manufacturing cost again of sprocket wheel.
