Description
Technical field
The present invention relates to the technical fields of machining, and in particular to a kind of skiving cutter for processing speed reducer pin wheel housing internal tooth
Tool and processing method.
Background technique
The internal tooth processing of speed reducer pin wheel housing is formed by Gear Shaping at present, processed pin wheel housing and pinion cutter
Tool processes the internal tooth tooth form of pin wheel housing according to the generating theory of engagement.Gear Shaping includes cutting movement, divides tooth generating motion,
Radial feed moves and knife is allowed to move.Cutting movement is that the upper and lower reciprocating motion of pinion cutter is used to cutting workpiece, is cut downwards
Stroke is cut, is then idle stroke upwards.Dividing tooth generating motion is that correct meshing relation should be kept between pinion cutter and workpiece, is inserted
Serrated knife tool makes a round trip, rotary feed of the workpiece with respect to pinion cutter when the arc length turned on reference circle is processing, therefore inserts
The engagement process i.e. rotary feed process of serrated knife tool and workpiece.Radial feed movement is in gear shaping, to be gradually switched to entirely
Tooth depth, pinion cutter should have radial feeds.Allowing knife to move is, in order to avoid pinion cutter abrades the machined flank of tooth and reduction
The abrasion of cutter tooth, when pinion cutter moves upwards, workbench drives workpiece to exit cutting region a distance radially, and inserts
Serrated knife has when carrying out down-cutting stroke, and workbench sets back again.
As it can be seen that Gear Shaping needs to process the gear teeth by stroke motion repeatedly, in cutting movement, pinion cutter is being held
It has gone and has carried out primary non-processing property backlash journey after cutting again, therefore led to the low efficiency of Gear Shaping.
