Abstract
The invention belongs to the field of equipment maintenance and provides a technique for rapidly repairing a broken gear shaft by using an implantation method. According to the invention, a broken part is analyzed and materials are selected for a part that is easy to get repaired as an implantation part. Materials of an original gear shaft are determined. As to the undetermined materials, materials having chemical components approximate to those of the original gear shaft are selected to be the implantation part through chemical analysis. Rough machining and heat treatment are performed on the materials of the implantation part according to technical requirements. At the same time, tenon-and-mortise connection is adopted for a connection part of a base part and the implantation part. The required strength of the implantation part is calculated and the length L and the thickness H of a tenon are determined. Finish machining of the tenon and a mortise is performed. Interference fit is adopted for tolerance fit and heat assembly is employed. After the tenon-and-mortise structure is assembled, finish machining of the implantation part is performed according to the technical requirements for the original gear shaft for meeting technical parameter requirements. The technique is quick in repairing, stable in working performance, long in service lifetime and low in implantation cost.
Description
Technical field
The invention belongs to maintenance of equipment field is and in particular to a kind of implantation quickly repairs the process of broken teeth wheel shaft.
Background technology
At present in maintenance of equipment field, to being worth high, more complicated gear shaft, rupture suddenly in operation, if its energy
Enough quick repair, and reach and use technical requirements, it will substantially reduce maintenance cost, especially extensive to the equipment in production line balance
Multiple equipment operation, if cause to shut down will result in great loss, and reduces, for can quickly repair, the technical scheme shut down,
Great effect will be played in this production process.
Content of the invention
The purpose of the present invention is for the complexity of restorative procedure present in existing technology, high cost, and technical requirements are difficult to
Problem up to standard, provides that a kind of rehabilitation cost is low, repairs that speed is fast, ensure that the implantation of technological parameter requirement is quickly repaired
The process of broken teeth wheel shaft.
For reaching above-mentioned purpose, adopted the technical scheme that:
A kind of implantation quickly repairs the process of broken teeth wheel shaft, comprises the following steps that:
1) analyze from fracture location, according to the fracture location of broken teeth wheel shaft, the part that complex structure is not easily repaired stays
Based on part, to be easier to repair part selection again, implanted as implant part；
2) original gear axial wood matter is determined, can directly determine the material conduct directly selecting phase same material of material
Implant part, for not can determine that material, by chemical analysis, selects to study the near material conduct of tap with original gear axiation
Implant part；
3) according to technical requirements, roughing and heat treatment are carried out to the material of implant part, simultaneously to foundation and implantation
Partial coupling part adopts mortise-tenon joint, and tenon and mortise are carried out with roughing, described tenon be in two ends be circular arc, in
Portion is the bluff body of parallel lines, and the intensity requirement of implant part is calculated, and determines described length l of tenon and thickness
h；
4) tenon and mortise are finished, tolerance fit adopts interference fit, assembling is joined using hot charging；
5), after the completion of joinery and its construction assembling, by original gear shaft technical requirements, implant part is finished, meet
Technical parameter requires.
In step 3), the intensity requirement for implant part is calculated by data below: the power that 1. axle is transmitted
(kw)；2. the rotating speed (r/min) of axle；3. the diameter (mm) of axle；4. allowable stress (the n/mm of axle2)；5. the moment of torsion that axle is transmitted
(n.m), by calculating and the inspection of above-mentioned parameter, determine multigroup l and h value, select optimal l and h value to carry out by method of comparison
Implantation.
Using technique scheme, acquired beneficial effect is:
The present invention by the above-mentioned problems in the prior art, carrying out the material of gear shaft by rational process
Selection, the shape of attachment structure and the calculating of parameters of structural dimension of material repair quick, service behaviour after implantation so that it has
Stable, long service life, and implant low cost, the production line for restorer operation of being eager has special effect.
Brief description
Fig. 1 is the structural representation of implant part.
The structural representation of part based on Fig. 2.
Fig. 3 is the structural representation of the gear shaft after implantation is repaired.
In figure sequence number: based on 1 part, 2 be implant part, 3 be tenon, 4 be mortise.
Specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
Referring to Fig. 1-Fig. 3, a kind of implantation is quickly repaired the process of broken teeth wheel shaft, is comprised the following steps that: 1)
From fracture location analysis, according to the fracture location of broken teeth wheel shaft, the part that complex structure is not easily repaired is left as basic courses department
Point, to the part selection again being easier to reparation, implanted as implant part；2) original gear axial wood matter is determined, energy
Enough directly determine material directly selects the material of phase same material as implant part, for not can determine that material, by changing
Credit is analysed, and selects to study the near material of tap as implant part with original gear axiation；3) to the material of implant part according to skill
Art requires to carry out roughing and heat treatment, adopts mortise-tenon joint to the coupling part of foundation and implant part simultaneously, and right
Tenon and mortise carry out roughing, described tenon be in two ends be circular arc, middle part be the bluff body of parallel lines, to implant part
Intensity requirement calculated, determine described length l of tenon and thickness h, for implant part intensity requirement by following
Data is calculated: the power (kw) that 1. axle is transmitted；2. the rotating speed (r/min) of axle；3. the diameter (mm) of axle；4. axle is allowable
Stress (n/mm2)；5. the moment of torsion (n.m) that axle is transmitted, by calculating and the inspection of above-mentioned parameter, determines multigroup l and h value, leads to
Crossing method of comparison selects optimal l and h value to be implanted；4) tenon and mortise are finished, tolerance fit is joined using interference
Close, assembling is joined using hot charging；5), after the completion of joinery and its construction assembling, by original gear shaft technical requirements, essence is carried out to implant part
Processing, meets technical parameter requirement.
