The specific embodiment
For the present invention is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Fig. 1 is horizontal five-axle linkage gear hobbing machining tool schematic diagram provided by the invention, described horizontal five-axle linkage gear hobbing machining tool comprises frame, hob head is arranged on frame by column 9, hob head with column 9 for being fixedly connected with, hobboing cutter 2 is housed on hob head, the first servomotor 1 connects hobboing cutter 2, the second servomotors 10 and connects column 9, and whole column partly is arranged in frame one side; Carriage 7 is arranged on opposite side on frame, and workbench 5 is arranged on carriage 7, around the 3rd servomotor 4 from the axle rotation, is contained in workbench 5, the four servomotor 8 connecting working table 5, the five servomotors 6 connection carriages 7 be used to driving non-knuckle-tooth base 3 to be processed.In Fig. 1, angle beta ± λ is hobboing cutter 2 established angles, need determine concrete "+" or "-" symbol according to actual processing method.
Non-knuckle-tooth base 3 to be processed is arranged on workbench 5, tooth base 3 be installed as horizontal installation, namely tooth base 3 axis are parallel with workbench 5 horizontal planes.
The first servomotor 1 drives hobboing cutter 2 around from axle, rotating; The second servomotor 10 drives ball screw and drives column 9, and the motion of column 9 drives the hob head motion makes hobboing cutter 2 along tooth base 3 axial feeds; The 3rd servomotor 4 driving gear bases 3 are around from axle, rotating; The 4th servomotor 8 drives workbench 5, and the tooth base 3 Yan Qi centers of installing on workbench 5 and hobboing cutter 2 centers are changed; The 5th servomotor 8 drives ball screw, and on ball screw, travelling nut and carriage 7 connect into an integral body, thereby drives carriage 7 motions, and workbench 5 is along 3 tangential motions of tooth base.

Horizontal five-axle linkage gear hobbing machining tool provided by the invention is mainly for the processing non-circular gear, especially helical teeth non-circular gear, it mainly is applicable to process the less non-circular gear in maximum utmost point footpath (non-circular gear), is particularly useful for four-axle linked gear hobbing processing non-circular gear method; The large or little large-scale helical teeth non-circular gear of material proportion also can adopt the five-axle linkage hobbing method on this lathe, to carry out gear hobbing processing for utmost point footpath.
When the small-sized non-circular gear of processing or helical teeth non-circular gear, at this moment adopt four-axle linked mode gear hobbing processing, its detailed process is divided into again two steps:
1) hobboing cutter does not have the feed along tooth base axial direction, be that hobboing cutter adds man-hour along tooth base circumference rolling cut, at this moment, four-axle linked gear hobbing processing, namely there are three axles to participate in interlock, be hobboing cutter around from axle motion, tooth base around from axle motion, hobboing cutter and tooth base centre-to-centre spacing change in displacement, this cutting movement is topmost cutting movement;
2) when hobboing cutter has along tooth base axial feed, motion state at this moment adds that hobboing cutter is four-axle linked around from axle motion, tooth base, becoming around from axle motion, hobboing cutter and tooth base centre-to-centre spacing change in displacement, linking, and this cutting hobbing motion is not topmost cutting movement.
When the little non-circular gear of machining large proportion or helical teeth non-circular gear, also can on lathe, adopt the processing of five-axle linkage gear hobbing processing method, adopt the gear hobbing of five-axle linkage mode to process its detailed process and be divided into again two steps:
1) hobboing cutter does not have the feed along tooth base axial direction, be that hobboing cutter adds man-hour along tooth base circumference rolling cut, at this moment, five-axle linkage gear hobbing processing, namely there are four axles to participate in interlock, be hobboing cutter around from axle motion, tooth base around from axle motion, hobboing cutter and tooth base centre-to-centre spacing change in displacement, hobboing cutter is along tangential the moving of tooth base circumference, this cutting movement is topmost cutting movement;
2) when hobboing cutter has along tooth base axial feed, at this moment motion state add hobboing cutter around from axle motion, tooth base around from axle motion, hobboing cutter and tooth base centre-to-centre spacing change in displacement, hobboing cutter, becoming five-axle linkage along the tangential interlock of moving of tooth base circumference, it is not topmost cutting movement that this cutting hobbing moves.
