Abstract
The invention relates to a method for processing an involute straight spur gear on a spline grinder, including the following steps: (1) producing a high precision profile shifted gear of which the parameters are consistent with that of a workpiece to be processed, (2) plating carbite or cubic boron nitride (CBN) particles on the profile shifted gear, (3) installing the profile shifted gear on the position of the workpiece of the spline grinder to correct the flank shape of a grinding wheel, and (4) grinding the processed straight spur gear by the grinding wheel with corrected flank shape. As the shaping method is used for processing the gear, only one tooth socket needs to be processed by the plating operation; after abrasive particles are worn, a clad layer can be peeled off, and the plating operation is carried out again, namely that the basic gear with the identical parameters just needs to be produced by one time, thus compared with the prior art, the processing and production cost is greatly reduced; and further more, under the circumstance that a special shaping mechanism is not used on the spline grinder, the flank shape of the grinding wheel can be accurately corrected, and the production difficulty is also greatly reduced.
Description
Technical field
The present invention relates to the Gear Processing field, specifically, relate to a kind of method of chemically making gear type diamond dressing gear.
Background technology
Involute cylindrical gear is the most widely used fundamental parts of mechanical transmissioning technology, is widely used in fields such as automobile, lathe, electric power, metallurgy, boats and ships, mine, Aeronautics and Astronautics.Along with more and more higher, need with using the gear-grinding process processing back flank of tooth that quenches, and satisfy a requirement such as gear-box precision that improves constantly the accuracy of gear, requirement of strength.
Teeth grinding method mainly is divided into generating and forming process at present.Generating is divided into the mill monodentate face method that comprises two dish (emery) wheel mills, big flat-faced wheel mill again, and the mill bidentate face method of worm abrasion wheel mill, the former working (machining) efficiency is low, and latter's grinding wheel dressing mode is special, and two dish (emery) wheel grinds, big flat-faced wheel grinding machine bed costs an arm and a leg.The forming process roll flute is the shape that crushing is become gear tooth slot, and the high speed rotation of emery wheel and the feed motion of emery wheel or workpiece combine, and process gear tooth slot.Formation teeth-grinding is a traditional teeth grinding method, especially is being applicable to large module gear and minority tooth, oil pump gear.Machine tool is simple, does not need complicated generating mechanism.The key problem in technology of forming process grinding is crushing, and commonly used have involute template corrector, an XY cam corrector etc., all needs special burring machine, correction of the flank shape cost height, and efficient is low, and precision should not guarantee.Spline shaft grinding machine has low, the advantages of simple structure and simple of price, and the transformation through suitable can be used for forming process grinding straight spur gear, but the finishing of emery wheel is a key issue, and existing remodeling method mostly needs the design specialized dresser, and efficient is low, the cost height.
Summary of the invention
The objective of the invention is to carry out deficiency in the grinding straight spur gear production process by transforming spline shaft grinding machine, a kind of novel method of utilizing spline shaft grinding machine grinding straight spur gear is provided at existing
Technical scheme of the present invention is: a kind of method of processing the straight-tooth involute cylindrical gear on spline shaft grinding machine, may further comprise the steps: 1) make a high accuracy profile shifted gear consistent with the workpiece to be machined parameter, 2) plated with gold hard rock or cubic boron nitride (CBN) particle on profile shifted gear, 3) profile shifted gear is installed in the location of workpiece of spline shaft grinding machine, the correction of the flank shape emery wheel, 4) with the processed straight spur gear of the wheel grinding after the correction of the flank shape.
Profile shifted gear is meant at (thickness after the thickness of tooth is to deduct diamond sand diameter) on the full-height tooth wheel body of steel and plates one deck diamond or cubic boron nitride (CBN) abrasive particle equably along the flank of tooth, because the hardness of diamond or cubic boron nitride is higher than the hardness of emery wheel, when work in-process is loaded onto freeing wheel, with trimming wheel, change workpiece, emery wheel will add work gear.
Profile shifted gear is behind plating, and its precision must be higher than the processed accuracy of gear.
Beneficial effect of the present invention is: owing to be that forming process adds work gear, only need teeth groove of plating, and behind the abrasive wear, coating can be peeled off, plating again, promptly the matrix gear of same parameter only need be made once, therefore the processing cost reduces greatly than prior art, and do not needing on the spline shaft grinding machine under the situation of special-purpose burring machine, the also emery wheel of correction of the flank shape accurately, the production difficulty also reduces greatly.
The specific embodiment
First specific embodiment of the present invention, a kind of method of processing the straight-tooth involute cylindrical gear on spline shaft grinding machine may further comprise the steps:
The first, make a profile shifted gear consistent with the workpiece to be machined parameter, its at least one teeth groove is carried out high-precision grinding, the thickness of tooth is the thickness that deducts behind diamond or the cubic boron nitride coating;
The second, adopt method plating last layer diamond or cubic boron nitride coating on the teeth groove that processes of plating or chemical plating;
Three, profile shifted gear is installed on the location of workpiece of spline shaft grinding machine, starts lathe, carry out normal process operation, freeing wheel is to grinding wheel dressing;
Four, freeing wheel is taken off, install workpiece to be machined, start lathe, carry out normal process operation, the wheel grinding workpiece.
Claims (3)
1. the method for a processing straight-tooth involute cylindrical gear on spline shaft grinding machine is characterized in that may further comprise the steps;
1) make the high accuracy profile shifted gear consistent with the workpiece to be machined parameter,
2) plated with gold hard rock or cubic boron nitride (CBN) particle on profile shifted gear,
3) then profile shifted gear is installed in the location of workpiece of spline shaft grinding machine, the correction of the flank shape emery wheel,
