Abstract
The invention discloses a kind of processing technology of ultra-thin gear ring, comprise the following steps：(1) be loaded blank with claw, and minimum diameter is machined to Φ 480, and cylindrical and height stays allowance 2mm；Excircle dimension Φ 545.5, height 53mm；(2) smart car tooth top：Smart car outside circle size is to drawing size, the compensation line of endoporus car one, with uniform six points of pressure of six pressing plates；(3) tooth processed：Tooth quenching, tempering；(4) smart car plane and endoporus：Hole size smart car three times, including half smart car and a smart car twice.Processing technology disclosed in this invention can ensure the tolerance dimension of ultra-thin gear ring within the specific limits, and precision is accurate.
Description
Technical field
The present invention relates to a kind of processing technology of gear ring, more particularly to a kind of processing technology of ultra-thin gear ring.
Background technology
The blank procurement practice of conventional gear ring class product is direct with buying size of the product inside/outside diameter size as blank.Blank enters
After factory, the production drawing that workshop is assigned according to technology department is processed：
1st, rough turn blank, stays allowance；2nd, rough turn track (such as need to be with blocking, first with blocking)；3rd, track is heat-treated；4、
Smart car plane；5th, line drilling；6th, smart car track.
The technique of rough turn blank is as follows：
Appearance and size allowance：Within orbit centre is away from 500mm, inside subtract additional 1.0mm；It is interior within 500~1400mm
Subtract additional 1.5-2mm；Subtract additional 2.0-2.5mm in more than 1400mm.Highly unilateral 0.5 ± 0.2mm of allowance, and both sides
Uniformly.
Ultrathin products refer to that products radial thickness is not more than 25mm product, easily deform in process, dimensional tolerance
It is difficult to control.
Need to carry out tooth quenching for external tooth class gear ring product (RG5.0101.2.0), more exacerbate the deformation of product.In product
Footpath size is Φ 495.2 ± 0.13, and conventional products technology controlling and process means are directed to depending on conventional products, big for those thickness and height
Product, common process can ensure machining accuracy and requirement, but if if processing the type super thin product, this technique
Product Precision can not be ensured.Because the thickness and height of conventional products can bear the stress produced during processing, the stress is not
Big deformation can be caused to product, simply Light deformation, on the premise of having allowance, on Product Precision be do not have it is influential.
Ultrathin products are processed under the requirement of common process, and the deformation of generation will substantially exceed the allowance reserved in technique, so that
Tolerance will be exceeded, product rejection is caused.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of processing technology of ultra-thin gear ring, to reach raising Product Precision,
Ensure the purpose of the margin of tolerance.
To reach above-mentioned purpose, technical scheme is as follows：
A kind of processing technology of ultra-thin gear ring, it is characterised in that comprise the following steps：
(1) be loaded blank with claw, and minimum diameter is machined to Φ 480, and cylindrical and height stays allowance 2mm；Excircle dimension Φ
545.5, height 53mm；
(2) smart car tooth top：Smart car outside circle size is to drawing size, the compensation line of endoporus car one, with the uniform pressure six of six pressing plates
Point；
(3) tooth processed：Tooth quenching, tempering；
(4) smart car plane and endoporus：Hole size smart car three times, including half smart car and a smart car twice.
In such scheme, the time interval of the smart car is more than 8 hours twice.
In further technical scheme, quenching bench is highly not less than 1.5mm during quenching.
Further in technical scheme, workpiece is uniformly pushed down with six pressing plates during the smart car.
The processing technology of the ultra-thin gear ring provided by above-mentioned technical proposal, the present invention is from the big blank of internal diameter size, blank chi
It is very little to thicken, blank intensity can be increased, machining deformation can be reduced in process；It is same by three smart cars during smart car
Sample can so ensure the tolerance dimension of ultra-thin gear ring with Reducing distortion.
Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below.
The invention provides a kind of processing technology of ultra-thin gear ring, specific embodiment is as follows：
The processing technology of ultra-thin gear ring (RG5.0101.2.0)：
(1) be loaded blank with claw, and minimum diameter is machined to Φ 480, and cylindrical and height stays allowance 2mm；Excircle dimension
Φ 545.5, height 53mm；
(2) smart car tooth top：Smart car outside circle size is to drawing size, the compensation line of endoporus car one, with the uniform pressure six of six pressing plates
Point；
(3) tooth processed：Tooth quenching, tempering；Quenching bench is highly not less than 1.5mm during quenching；
(4) smart car plane and endoporus：Hole size smart car three times, including half smart car and a smart car twice, with six during smart car
Pressing plate uniformly pushes down workpiece, to unclamp pressing plate at any time in process, discharges stress；The time interval of smart car is more than 8 twice
Hour.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or using the present invention.To these
A variety of modifications of embodiment will be apparent for those skilled in the art, generic principles defined herein
It can realize in other embodiments without departing from the spirit or scope of the present invention.Therefore, the present invention will not be by
It is limited to the embodiments shown herein, and is to fit to consistent with features of novelty with principles disclosed herein most wide
Scope.
