It is gradually increased on the direction that one end of essence gear rolling extends.
Further, on the thick gear rolling and finishing teeth the tooth root of teeth on sustained height.
Further, the distance between tooth top and tooth root of teeth are rubbing the one of separate smart gear rolling with the hands from thick on the thick gear rolling
It is gradually increased on the direction for holding the one end to connect to thick gear rolling with smart gear rolling to extend.
Further, the thick gear rolling, finishing teeth, finishing teeth and the part tooth form of tooth is exited using going toothing to set
Meter goes tooth section and orthodont using going up or down stairway shape that is, on the longitudinal section of teeth, intermediate to be connected by chamfering.
Further, described to be that the product external splines one after processing encloses tooth and there is two spline one end simultaneously tooth, and outside tooth
Spline workpiece can realize and go the cooperation of tooth internal spline to ensure that assembly, increase the tightness of cooperation, improve the fortune of transmission
Dynamic rigidity.
Further, described to be to cause product surface when workpieces processing the mass defects such as scuffing, burr, safety
Reliably.
The application provides a kind of multiple spline gear rolling knife of band guiding processing, is mainly used for machine direction arbor, drive shaft, transmission
The processing of the external splines such as axis, gear rolling knife is by thick gear rolling, smart gear rolling, finishing teeth and exits tooth and forms, reasonable in design, simplify,
Converted products precision is high.When carrying out gear rolling processing to components, part surface layer is applied using the gear rolling knife of the application certain
Pressure makes part coating metal that plastic degeneration occur, to improve product roughness and hardness, final gear rolling is formed and tooth flower
Key.It is the difference disconnected with metallic fiber in machining mode used at present, the spline with guiding processing of the invention is rubbed with the hands
The metallic fiber of serrated knife processing be it is continuous, thus, had following technical effect that using the spline that the present invention processes
(1), the surface roughness of workpiece to be machined is improved；
(2), the surface hardness for improving the hardness and strength of workpiece to be machined coating metal, especially tooth or tooth bottom has
Very big increase；Spline tooth top two sides are arc transition after rubbing processing with the hands；
(3), good in economic efficiency, work efficiency can be improved several times to tens times compared with machining, and easily realize automation, big
There is very high productivity in batch production and cutter life is high；
(4), multiple spline gear rolling is processed as ELEMENTARY INTRODUCTION TO NON, can save raw material；
(5), the workpiece and tooth being processed into, substantially increase the precision of assembly, improve the degree of engagement of assembly.

Specific embodiment:
Invention is further described in detail with reference to the accompanying drawings and detailed description.
Referring to Fig.1~Fig. 6, a kind of multiple spline gear rolling knife of band guiding processing, including cutter hub 1 and spline tooth 2, the cutter hub 1
Be equipped with the thick gear rolling being arranged successively, smart gear rolling, finishing teeth and exit tooth composition, the thick gear rolling, smart gear rolling, finishing teeth and
Tooth is exited to be sequentially distributed along the length direction of cutter hub；The spline tooth includes orthodont, goes tooth section.
The left side of spline tooth 2 to the right side of spline tooth 2, the tooth top of spline tooth 2 successively include that left section 21 of tooth top and tooth top are gone
Tooth section 22, left section 21 of tooth top and tooth top go among tooth section 22 to be connected by chamfering, 2 left side of left section 21 of tooth top and spline tooth, preceding
Trailing flank seamlessly transits；2 right side of right section 22 of tooth top and spline tooth, front and back sides seamlessly transit.
Left section 21 of tooth top and right section of tooth top are made a return journey tooth not in a height according to spline tooth number, and a circle removes a tooth, this
Kind structure makes spline teeth 2 after the circle of processing one, a convex surface is formed in certain two spline surface, to go tooth to spend for forming
Key
The distance between teeth tooth top and tooth root are less than between finishing teeth teeth tooth top and tooth root on the thick gear rolling
Distance.
The outside pitch line length for exiting teeth on tooth is close smart to tooth is exited in one end from the portion that exits far from smart gear rolling
It is gradually increased on the direction that one end of gear rolling extends.
The tooth root of teeth is on sustained height on the thick gear rolling and finishing teeth.
The distance between tooth top with tooth root of teeth are rubbing one end far from smart gear rolling with the hands to thick from thick on the thick gear rolling
It is gradually increased on the direction that one end that gear rolling connects with smart gear rolling extends.
The thick gear rolling, finishing teeth, finishing teeth and the part tooth form for exiting tooth is existed using going toothing to design
On the longitudinal section of teeth, go tooth section and orthodont using going up or down stairway shape, it is intermediate to be connected by chamfering.
Product external splines one after processing encloses tooth, and there are two spline one end and teeth, and tooth external splines workpiece can be realized and be gone
The cooperation of tooth internal spline ensure that assembly, increase the tightness of cooperation, improve the movement rigidity of transmission.
The mass defects such as scuffing, burr will not be caused when workpieces processing to product surface, securely and reliably.
The application provides a kind of multiple spline gear rolling knife of band guiding processing, is mainly used for machine direction arbor, drive shaft, transmission
The processing of the external splines such as axis, gear rolling knife is divided into thick gear rolling, smart gear rolling, finishing teeth and exits toothed portion, reasonable in design, smart
Letter, converted products precision are high.The application is squeeze to part surface layer using gear rolling knife forming simultaneously tooth spline, makes part surface layer
Plastic degeneration occurs for metal, to improve product roughness and hardness.
The application and currently used machining mode have significant difference, the spline of the application band guiding processing
The inside workpiece metallic fiber of gear rolling knife processing is continuous.The workpiece processed as a result, has the advantage that
A, the surface roughness of workpiece to be machined is improved.
