Abstract
The utility model relates to the technical field of roller, specifically to a roller with a dovetail groove combined structure. The roller comprises a roll shaft and a roll block. The roller further comprises a triangular wedge-shaped strip and limiting protective rings. A plurality of dovetail grooves are arranged uniformly on the cylindrical surface of the roll shaft. The roll block is a dovetail-like structure matched with the dovetail groove and assembled in the dovetail groove. The triangular wedge-shaped strip is embedded into a gap between the roll block and the dovetail groove assembled so that the roll block and the roll shaft are assembly more tightly. Both ends of the roll shaft are respectively provided with the limiting protective rings after the roll block, the triangular wedge-shaped strip and the roll shaft are assembled. Compared with prior art, common raw materials and valuable steels after surface hardening are combined safely and effectively through the triangular wedge-shaped material by means of structural uniqueness of the dovetail groove and both ends are matched with the limiting protective structure to obtain high hardness on the rolling surface and reliable rotation at high speed.
Description
Technical field
The utility model relates to the roll technology field, specifically a kind of dovetail groove combining structure roll.
Background technology
The roll that uses in the existing industry has: monoblock type, tubular sleeve type, inserted.
1. monoblock type: waste of raw materials is serious, and after surface hardening handled, hardness did not reach requirement;
2. tubular sleeve type: valuable steel waste of raw materials is serious, and after surface hardening was handled, hardness reached requirement, but technology is too numerous and diverse after the process and assemble, has improved labour cost;
3. inserted: valuable steel raw material are saved, dismounting, easy to maintenance, but utilization has limitation, is not suitable for comprehensive being applied.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art; A kind of dovetail groove combining structure roll is provided, has solved the problem of valuable steel raw material material waste effectively, can reach industrial desired hardness again; Be convenient to dismounting and safeguard, and can be applied comprehensively.
In order to achieve the above object; The utility model has designed a kind of dovetail groove combining structure roll; This roll comprises roll shaft, roller piece; It is characterized in that: also comprise triangle steel spline and position limitation protection circle, the face of cylinder of roll shaft evenly offers several dovetail grooves, and the roller piece is for the swallowtail-shaped structure that agrees with mutually with dovetail groove and be assemblied in the dovetail groove; The triangle steel spline embeds in the slit after roller piece and the dovetail groove assembling roller piece and roll shaft is assembled more closely, and the two ends of roll shaft also are respectively fitted with the position limitation protection circle after roller piece, triangle steel spline and roll shaft assemble.
Described position limitation protection circle adopts bolts assemblies on roll shaft.
The utility model is compared with prior art; Adopt dovetail groove particular structure characteristic; Valuable steel after letting common raw materials and process surface hardening handle; Combine through triangle wedge of material effective and safe ground, two ends cooperate the position limitation protection structure, reach the roller surface high rigidity, high speed is rotated reliable purpose.
Description of drawings
Fig. 1 is the assembly structure sketch map of the utility model.
Fig. 2 is the partial enlarged drawing at B place among Fig. 1.
Referring to Fig. 1,1 is roll shaft; 2 is the roller piece; 3 is the triangle steel spline; 4 is spacing guard circle; 5 is bolt.
The specific embodiment
Combine accompanying drawing that the utility model is further specified at present.
As shown in Figure 1; The utility model comprises roll shaft 1, roller piece 2; Also comprise triangle steel spline 3 and position limitation protection circle 4, the face of cylinder of roll shaft 1 evenly offers several dovetail grooves, and roller piece 2 is for the swallowtail-shaped structure that agrees with mutually with dovetail groove and be assemblied in the dovetail groove; Triangle steel spline 3 embeds in the slit after roller piece 2 assembles with dovetail groove roller piece 2 and roll shaft 1 is assembled more closely, is the partial enlarged drawing at B place among Fig. 1 like Fig. 2; The two ends of roll shaft 1 also are respectively fitted with position limitation protection circle 4 after roller piece 2, triangle steel spline 3 assemble with roll shaft 1, position limitation protection circle 4 adopts bolt 5 to be assemblied on the roll shaft 1.
The making principle of the utility model is following:
1. adopt medium carbon steel processing and modified, after the CNC machining center is made into roll shaft 1;
2. adopt import or high-quality sintered steel roughing to become roller piece 2 and reach the size that requires; After carry out high-frequency quenching; Reach desired high rigidity; The dovetail groove that finish grindes again with roll shaft 1 assembles, and knocks in triangle steel spline 3 in the slit at last, lets roll shaft 1 and roller piece 2 tight reliable fit together;
3. processing position limitation protection circle 4 lets position limitation protection circle 4 and roll shaft 1 closely cooperate to requiring size through the hot jacket skill, carries out fastening through bolt 5 again.
Claims (2)
