Description
Technical field
The present invention relates to gear grinding technical field, more particularly to a kind of magnetic fluid flexbile gear grinding attachment.
Background technology
Gear is as the basic part of machine, and its workmanship can reflect the aggregate level of an epoch machine-building, machine
High speed, high accuracy, high bearing capacity, low noise and the high reliability development trend of tool transmission are proposed more to gear manufacture precision
High requirement, high class gear is finished sometimes for using gear-grinding process.
The present invention is mainly based upon following factor and proposed：
Due to the limitation of existing gear-grinding process, the grinding of current gear is still processed using by tooth, and grinding efficiency is low, and due to
Grinding tool size is limited, and existing gear-grinding process can not be ground the gear that modulus is less than 0.3mm, therefore, for more than the number of teeth and modulus is small
Gear, it is necessary to develop new and effective roll flute processing technology.
Device that the utilization magnetic fluid proposed before inventor is ground to flexbile gear (Deng Man, a kind of profits of such as Xin Hongbing
The method scientific and technical innovations and application, 2016 (6) of roll flute are carried out to flexbile gear with magnetic fluid：48) in, there is problems with：1) it is variable
Its cylindrical core body is not kept inside the thin-wall member flexbile gear of shape, in grinding, thin-walled deformation of flexible wheel will cause to add
Gear ring and the tooth form distortion of work.2) because mechanism kinematic rule is limited, slider-crank mechanism makes the soft of magnet gradient magnetic formation
The relative cutting movement speed of property bistrique and flexbile gear is non-constant, and flank of tooth Grinding Machining Quality is uneven.3) it is in process, close
Magnetic fluid in capsule body can not be updated, and the abrasive material of rust and chip can not be discharged.
In magnetic fluid gear grinding device proposed by the present invention, it is mounted with to keep its cylindrical post inside thin-walled flexbile gear
Body, the relative motion that slider-crank mechanism produces flexible bistrique and gear ring, control cutting movement speed are substituted with magnetic field control device
Degree keeps constant, updates the magnetic fluid in seal casinghousing using fluid control systems, overcomes the defect of former scheme.
The content of the invention
The present invention uses following technical scheme：
The present invention had not only had solid magnetic but also the property with liquid fluidity using magnetic fluid, the magnetic current added with abrasive material
Body is input in the gear tooth slot of rotation, in the presence of gradient magnetic, and the interior magnetic fluid added with abrasive material of teeth groove is in gradient magnetic
Active region forms the flexible bistrique that soft solidity gos deep into flexbile gear or firm gear teeth groove, by controlling magnetic field, makes flexible bistrique and gear teeth
Circle produces relative motion, and in the presence of abrasive material near flexible bistrique, gear-wheel gear-ring obtains grinding.
Ground gear is fitted into housing, the ground gear rotation of drive device driving, fluid control systems pass through defeated
Enter pipeline by the magnetic fluid input gear teeth groove containing abrasive material, the equal distributed magnetic field of multiple stations is filled in circumference of gear direction
Put, under magnetic field control device effect, the flexible bistrique that each station is produced in gradient magnetic produces relative motion with teeth groove,
So as to reach the purpose of roll flute.Fluid control systems control the scrap under the input and output of the magnetic fluid containing abrasive material, mill timely
Drain, due to being distributed multiple field generator for magnetic on roll flute wheel circumferencial direction, therefore technical scheme proposed by the present invention can be with
Gear grinding efficiency is improved, and because working media is the fluid containing abrasive material, the present invention cannot be introduced into teeth groove available for emery wheel
Fine module gear roll flute.
Beneficial effects of the present invention：
Magnetic fluid gear grinding device proposed by the present invention, substitutes slider-crank mechanism with magnetic field control device and produces flexibility
The relative motion of bistrique and gear ring, control cutting movement speed keeps constant, is updated using fluid control systems in seal casinghousing
Magnetic fluid, because abrasive material size is small, can to modulus be more than abrasive material size gear be ground, be particularly it is more to gear
Fine module gear, improve production efficiency.
