Abstract
The present invention has announced a kind of new-type involute gear lapper.Its maximum characteristics are that workpiece gear is driven by separately power source in process of lapping, carry out high speed by gearratio and evenly turn round.In the rotating while, the centre distance of gear is done slowly along the path of contact direction and is moved back and forth, and workpiece gear also does relative motion in the teeth directional direction.Present device is simple, can obtain desirable involute profile with phase gear to grinding, and the gear lapping precision can be beautiful with the gear grinding machines ratio with production efficiency, is applicable to and produces high-precision hardened face gear in enormous quantities.
Description
The present invention is a kind of gear finish machining equipment, is applicable to utilize grinding agent to process high class precision hardened face gear, and its production efficiency is higher and the device fabrication cost is wanted much less than gear grinding machines.
Present involute gear gear lapping, no matter the lap tool gear lapping is arranged or to grinding running-in, all to be the lap tool gear become main passive relation with workpiece gear or two workpiece gears and turn round.The major defect of this gear lapping method is to guarantee to obtain correct involute profile, and therefore the workpiece gear interchangeability of grinding out is relatively poor.
Gear lapping machine of the present invention, its theoretical foundation are that conjugate profiles principle and gear transmission are learned, and utilize flank of tooth dynamic engagement power to be gear fine finishining service.
Gear lapping machine of the present invention, it is strong to have rigidity, the lathe body that dynamic property is good and simple in structure.Can be designed to vertical (seeing accompanying drawing) or horizontal type structure, the parts title in the accompanying drawing is as follows: 1. fuselage, 2. workbench, 3. workpiece gear drive system, 4. flywheel, 5. mandrel, 6. workpiece gear, 7. table drive system, 8. teeth directional drive system, 9. electric demonstration and control system.
During gear lapping, workpiece gear is done high speed rotary, relatively moves in order to avoid grind out step-like between the teeth directional simultaneously.The part that shows unique characteristics of this gear lapping machine can reduce following some:
One, ginseng gear lapping wheel all is a workpiece gear, in the gear lapping process, no matter they before entering engagement or after entering engagement, are all done at the uniform velocity high speed backlash and change.
Two,, the dynamically balanced flywheel of the very big process of rotary inertia is housed on its mandrel in order to make the workpiece gear running speed even.
Three, the work spindle driven gear mandrel that is arranged in parallel and does high speed rotary, by drive power source (as variable-frequency motor) separately, revolution speed ratio between the mandrel to equal the theoretical gearratio of workpiece gear before grinding with regard to furnishing, is led passive relation so it doesn't matter between workpiece gear at workpiece gear.
Four, the center of the some workpiece gears in two workpiece gears moves back and forth slowly along a certain straight line (as the gear meshing line) direction perpendicular to the mandrel direction, so that the centre-to-centre spacing of workpiece gear is changed, guarantees to obtain involute profile.
Five, workpiece gear has short-range relatively slowly reciprocating motion in the teeth directional direction.
In addition, in order to improve gear lapping efficient and the different processing requests that adapt to gear, can use multi-form during gear lapping and grinding agent consumption.
Claims (4)
1, involute gear lapper is according to the mechanical kinetics principle, carries out the even rotating workpiece gear of high speed by a pair of by theoretical gearratio, under the situation of center distance change, by realizing the accurately machined purpose of gear to grinding.
2,, it is characterized in that the workpiece gear main shaft drives with separately power source to do high speed rotary that the revolution speed ratio is adjusted to the gearratio that equals the gear lapping wheel by the gear gear lapping machine of claim 1 regulation.
3,, it is characterized in that the centre-to-centre spacing of gear lapping process middle gear will be done change slowly by the gear gear lapping machine of claim 1 regulation.
4, by the gear lapping machine of claim 1 and 2 regulations, it is characterized in that on the mandrel of workpiece gear, being in series with the dynamically balanced flywheel of the very big process of rotary inertia.
