Description
Technical field
The utility model belongs to gear machining apparatus technical field, and in particular to a kind of straight bevel gear high precision numerical control mill
Tooth machine.
Background technology
Y7125 type gear grinding machines are a kind of big plane grinding-wheel gear grinding machines of the production fifties in last century, are China's cutters for gear wheel
The important equipment of processing is mainly used for being ground cutters for gear wheel and the master gears such as gear shaver, pinion cutter, obtains at home extensive
Using equipment performance there is no other substitute products.But Y7125 type gear grinding machines have stopped production, it is several original needed for main work
It fills (equi-index plate, lobe plate, flexible axle, change gear, core bar etc.), it is deposited fewer and fewer in the market in decades, what lathe needed in itself
Accessory basically can not be purchased；Domestic market production pinion cutter, the lathe of gear shaver product, except this old-fashioned Y7125
Roll flute type there is no alternative type.The Y7125 roll flute types that domestic market possesses, except the main body of lathe in itself
Lathe bed and portion body grinding wheel head structure can recycle outside by reparation, remaining mechanical transmission structure precision is lost, exhausted big portion
Extension set bed is currently in difficult production, and required precision is difficult to meet the requirement of modern industry.The numerical control of domestic lathe production
Gear grinder, mainly using turbine and worm auxiliary structure, abrasion is larger, and be machined, assembling and setting etc. it is a variety of not
Certainty factor influences, and transmission process inevitably there are drive gap, then influences transmission accuracy, and precision is difficult to protect for a long time
Card, using effect are unsatisfactory；This gear grinding machines the cutter of grinding different parameters need to readjust workbench inclination angle or
