The split welded type chain wheel uses a split welded type structure, thereby effectively solving the technical problems in production, reducing the complexity and manufacturing costs, and greatly shortening the production cycle.
Description
Technical field
The utility model relates to the scraper chain drive disk assembly on a kind of coal mine scraper conveyor, particularly a kind of sprocket wheel that is used to drive scraper chain.
Background technology
Sprocket wheel in the slat conveyer is the vitals of pulling scraper chain, is driven the scraper chain running and is played the effect of transporting coal by sprocket wheel.Along with the improving constantly of slat conveyer power and fortune coal ability, the physical dimension of sprocket wheel constantly increases, and its mechanical characteristics is required also to improve constantly in recent years, and original low power sprocket wheel can not satisfy the needs of use far away.In order to satisfy these requirements, the sprocket wheel of enormous size can not adopt traditional die-forged mode to manufacture.General manufacture method is to forge a columniform blank, the method machine-shaping of machine up then with the method for open die forging at present.Because the geometric configuration complexity very of sprocket wheel, these processing need be processed on numerical control machining center or numerical control borer, and need the waste material that eliminates a lot of in the processing, and processing capacity is very big, difficulty of processing and production efficiency are extremely low, and waste of material is also very serious.Productive costs height not only, and can not satisfy the requirement of delivery cycle, become the bottleneck that slat conveyer is manufactured.
The utility model content
The utility model provides a kind of split welded type sprocket wheel, solve existing sprocket wheel and be subjected to dimensional restriction, and processing is inconvenient, productive costs height, inefficient technical matters.
The technical scheme that its technical matters that solves the utility model adopts is:
This split welded type sprocket wheel, sprocket wrap is evenly distributed with sprocket, the axle center hole place of sprocket wheel has keyway, described sprocket wheel is welded by sprocket body and sprocket split assembling, sprocket body is evenly distributed with teeth groove along circumference, teeth groove has been embedded in sprocket, the tooth root portion of sprocket and the welding of the teeth groove on the sprocket body.
Described sprocket is double, sprocket body is evenly distributed with inside and outside two circle teeth groove along the inner edge and the outer rim of circumference, between the inside and outside two circle teeth groove spacer portion is arranged, the corresponding embedding has inner ring sprocket and outer ring sprocket in the inside and outside two circle teeth groove, the inside and outside two circle teeth groove welding on the tooth root portion of inner ring sprocket and outer ring sprocket and the sprocket body.
The tooth root of described sprocket is shaped as rectangle, trapezoidal or circular arc.
Every circle number of teeth of described sprocket is 5～12.
The crown of described sprocket is shaped as involute shape, cycloidal, circular arc, taper or trapezoidal.
The beneficial effects of the utility model are as follows:
The utility model is later-model split welded structure with sprocket design, and assembly welding is shaped then.This sprocket wheel is made up of two parts, and the blank of sprocket body is a set type structure, but diameter is much smaller than the maximum gauge of sprocket wheel, can adopt open die forging or directly produces with the mode of round steel blanking, and production technology is very simple.Be processed with well-distributed teeth groove in a circumferential direction on the sprocket body, can process on general machine tool, these teeth groove are as the embedding teeth groove of sprocket, hold sprocket and play the effect of the location and the support chain gear teeth.Sprocket is small-sized, and is simple in structure, can adopt common die forging mode to carry out in batches production, highly efficient in productivity, and significantly is better than the sprocket that machine up is made behind the open die forging through its metal structure structure of sprocket that die forging is produced.To the mechanical characteristics that improves sprocket wheel with very big effect is arranged service life.
The advantage of this split welded type sprocket wheel:
1, manufacture difficulty reduces greatly, and each several part all can be produced on conventional equipment.
2, sprocket can carry out batch manufacturing with die forging, the efficient height, and performance is good.
3, processing capacity significantly reduces, and increases work efficiency, and shortens the production cycle.
4, improve stock utilization, reduce material cost.

The specific embodiment
Embodiment is referring to Fig. 1, shown in Figure 3, this split welded type sprocket wheel, sprocket wrap is evenly distributed with sprocket, the axle center hole place of sprocket wheel has keyway 5, described sprocket wheel is welded by sprocket body and sprocket split assembling, sprocket body 1 is evenly distributed with teeth groove along circumference, and teeth groove has been embedded in sprocket, the tooth root portion of sprocket and the welding of the teeth groove on the sprocket body 1.
Referring to Fig. 2, shown in Figure 4, described sprocket is double, sprocket body 1 is evenly distributed with inside and outside two circle teeth groove along the inner edge and the outer rim of circumference, between the inside and outside two circle teeth groove spacer portion 4 is arranged, the corresponding embedding has 7 inner ring sprockets 2 and 7 outer ring sprockets 3 in the inside and outside two circle teeth groove, the inside and outside two circle teeth groove welding on the tooth root portion of inner ring sprocket 2 and outer ring sprocket 3 and the sprocket body 1.
Referring to Fig. 5, shown in Figure 6, the tooth root of sprocket is shaped as rectangle, and crown is shaped as involute shape, cycloidal, circular arc, taper or trapezoidal.
Job operation of the present utility model is as follows: split welded type sprocket wheel of the present utility model, sprocket body and sprocket can be produced respectively, and assembly welding becomes whole then.After the sprocket body blank carries out turning processing, the reprocessing teeth groove.Sprocket adopts the die forging batch manufacturing, after simply processing, carries out assembly welding in the teeth groove of insertion sprocket body and forms whole sprocket wheel, carries out fine limit work behind the assembly welding again, has promptly finished whole production processs.
