Description
Technical field
Present invention relates particularly to the comminution method of a kind of three-section wave raceway.
Background technology
Petal waveform race bearing is mainly used in having on the main frame of the requirement of special operation condition, such as its outer rolling of Aero-engine Bearing
Road is three-section wave shape.Petal waveform refers to that raceway is rendered as equally distributed waveform at circumferencial direction, class after the amplification of its shape
Floweriness lobed, so gaining the name, the difference of its Wave crest and wave trough is typically between 0.05～0.15mm.
Petal waveform bearing collar path is the working surface of bearing, its geometric accuracy, shape, surface roughness, surface
Stress state, metamorphic layer residual volume all directly affect the quality of bearing, which determine the running accuracy of bearing, bearing capacity and longevity
Life etc..Owing to bearing outer ring ball track is that non-circular structure, traditional handicraft and equipment cannot realize microstoning, does not possess at lappingout and add
In the case of work ability, the technique that the banding grinding-materials such as sand paper are polished can only be used, bearing ring raceway face is entered
Row polishing, it is to make grinding-material be pressed on bearing collar path surface, bearing ring closely by manual pressure mode
Make centering circular-rotation, it is achieved the removal of bearing collar path surface metal-layer.Its deficiency and defect: due to whole processed
Journey is manual pressure, it is impossible to applies identical pressure at bearing ring circumferencial direction, causes the gold on bearing collar path surface
Belong to removal amount different so that difference occurs in the stress on bearing collar path surface, and the bearing capacity of bearing occurs in that difference the most therewith
Different, this leverages the service life of bearing.The surface roughness of bearing collar path is also unable to reach technological requirement simultaneously,
Cause bearing collar path to wear and tear, this reduces the service life of bearing.This manual pressure mode cannot meet bearing holder (housing, cover)
The geometric accuracy of circle raceway, reduces the running accuracy of bearing.Along with the continuous lifting of host performance, to required bearing also to
High accuracy and high stability direction is developed, problem above exists so far and is effectively solved.
Summary of the invention
It is an object of the invention to provide the comminution method of a kind of three-section wave raceway, logical to solve three-section wave raceway
The mode of the manual pressure crossing routine cannot meet the geometric accuracy of bearing collar path, causes the abrasion of bearing collar path,
The problem reducing the service life of bearing.
The present invention solves that above-mentioned technical problem adopts the technical scheme that:
A kind of comminution method of three-section wave raceway, it is characterised in that: this comminution method comprises the following steps:
Multiple processing workpiece are carried out grinding by step one: grinding: take multiple processing workpiece one by one, and grinding is every
Form one after the grinding datum level A of individual processing workpiece and treat microstoning workpiece；
Step 2: just configuration and superfinishing datum level selected: utilize full-automatic Superfinishing machine and lathe to cooperate and treat
Microstoning workpiece carries out fine ginding processing, sets each grinding datum level A treated in microstoning workpiece as full-automatic super
Superfinishing datum level to be processed in essence machine；
Step 3: treat the location work of microstoning workpiece: multiple in step one treat that microstoning workpiece uses the right side
Enter in the order full-automatic Superfinishing machine of entrance that a left side goes out, first treat that microstoning workpiece is placed in full-automatic Superfinishing machine one by one by multiple
Conveyer belt on formed work aligning, the backstop in full-automatic Superfinishing machine treats that by first microstoning workpiece is from work aligning
Separate, and by material returned arm, first is treated, and microstoning workpiece is delivered on the station in full-automatic Superfinishing machine, treats for first
Microstoning workpiece is fixed on oilstone frame by contact roller assembly；
Step 4: oilstone work is set: oilstone is arranged on the hold down gag in full-automatic Superfinishing machine and oilstone with
Constant voltage equipment in full-automatic Superfinishing machine is connected, and treats that microstoning workpiece is affixed for first in the abradant surface of oilstone and step 3
Tightly；
Step 5: microstoning works: start control system, oilstone frame starts to rotate under the effect of control system, its
Rotating speed is 2000～2500rpm, simultaneously oilstone under the drive of oilstone frame along first bearing ring treating microstoning workpiece
Raceway width is reciprocating, then treats that microstoning workpiece is executed by the swing unit in full-automatic Superfinishing machine to first
Add amplitude be 0.5mm, frequency be the concussion of 20～25 hertz, finally by cylinder and constant voltage equipment, oilstone applied constant hanging down
Straight in the pressure of first bearing collar path treating microstoning workpiece；
Step 6: the superfinishing process of other workpiece and first treat the superfinishing process of microstoning workpiece with
Reason, forms lobed raceway after superfinishing all completes, and swing unit all returns to await orders in situ, and drawing mechanism is by lobed rolling good for superfinishing
Conveyer belt is sent in road one by one back to, and last multiple lobed raceways are sent lathe.
The method have the advantages that
1, the present invention has versatility, it is possible to improve the geometric accuracy of petal waveform bearing collar path, shape, rough surface
Degree, surface stress, metamorphic layer residual volume all directly affect the quality of bearing, correct grinding to bearing ring working surface,
The defect that i.e. workpiece middle (center) bearing lasso raceway causes, enables to meet the precision of bearing and life requirements.
2, by oilstone frame, oilstone and constant voltage equipment cooperate can make the bearing ring of workpiece realize high rotating speed and
Concussion at a high speed, high rotating speed and high speed concussion can fully improve the cutting force of oilstone, and the reciprocating motion of oilstone ensure that bearing holder (housing, cover)
Circle raceway shape of generatrix, the constant of oilstone pressure guarantees the uniform of bearing collar path circumferencial direction metal removal rate.
