Description
Technical Field
The utility model relates to a sprocket, especially a scrape trigger combination sprocket belongs to mining equipment technical field.
Background
The scraper conveyor is a typical industrial chain transmission mechanism, the power transmission of the scraper conveyor drives a circular chain to rotate through a driving chain wheel, when equipment works, the teeth of the chain wheel inevitably and directly rub against the circular chain, and when the teeth of the chain wheel are abraded to a certain degree, the teeth of the chain wheel must be replaced, the service life of the chain wheel is generally short, and particularly in the steel industry, the service life of the chain wheel is short.
The existing chain wheels mostly adopt castings, the service life of the chain wheel is seriously influenced due to casting defects of air holes, sand holes, slag inclusion and the like, and particularly, the chain climbing phenomenon easily occurs due to the deviation of the size of a casting chain pit; and the chain wheel is also integrally forged, and then is machined and formed by a numerical control machine, so that the chain nest machining cost is high.
The utility model patent 'a split type scraper chain wheel', the patent number of 201320399814.8, the grant announcement day 2013 12 months 18 days, mainly exist not enoughly: the process is complex and the processing cost is high.
The utility model provides a sprocket that processing cost is low, wearability is high, long service life.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: in order to solve the problems, the scraper chain wheel is provided.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a scrape trigger sprocket, includes the half teeth of a cogwheel and wheel hub, its characterized in that, two half teeth of a cogwheel set up on the wheel hub excircle, and two half teeth of a cogwheel are in chain nest department welding, the outside hole and the wheel hub welding of two half teeth of a cogwheel.
As a further description of the above technical solution:
the half gear adopts precision die forging, and the material of the half gear is 42 CrMo.
As a further description of the above technical solution:
the hub is made of 40Cr thick-wall seamless steel tubes in a blanking mode.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. the utility model discloses in, half gear adopts accurate die forging, and its material is 42CrMo, and the teeth of a cogwheel adopts two half gear welding as an organic wholes, and half gear adopts accurate forging, can reduce whole die forging expense, solve chain nest size deviation problem and climb the chain phenomenon, and adopts digit control machine tool machine-shaping when the sprocket adopts whole forging, avoids processing chain nest problem with high costs.
2. The half gear teeth are made of 42CrMo, are welded with a hub and then are subjected to integral modulation treatment, finally, the high-frequency quenching is performed on the teeth, the chain pit hardness HRC55-60 is high in wear resistance, the hub is made of thick-wall seamless steel tubes, the material is 40Cr, and the half gear teeth mainly have the following functions: the thick-wall seamless steel pipe is adopted for blanking, the material utilization rate is high, the cost is low, the forging cost and the casting defect are overcome, the material is 40Cr, the welding performance is good, the integral quenching and tempering treatment is carried out after the welding with the half gear, and the mechanical performance of the core part is good.
