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, be specifically related to the process that a kind of implantation is repaired broken teeth wheel shaft fast.
Background technology
At present in maintenance of equipment field; the gear shaft of, more complicated high to being worth; unexpected fracture in service; if it can be repaired fast, and reach operation technique requirement, will greatly reduce maintenance cost; equipment restorer running in especially streamline being produced; if caused, shut down and will cause great loss, and reduce the technical scheme of shutting down for repairing fast, will in this production process, play great effect.
Summary of the invention
The object of the invention is for the restorative procedure complexity, the cost that exist in existing technology high, specification requirement is difficult to problem up to standard, provides that a kind of rehabilitation cost is low, reparation speed is fast, can guarantee that the implantation of technological parameter requirement repairs the process of broken teeth wheel shaft fast.
For achieving the above object, the technical scheme of taking is:
Implantation is repaired a process for broken teeth wheel shaft fast, comprises following processing step:
1), from fracture location analysis, according to the fracture location of broken teeth wheel shaft, the part that complex structure is difficult for repairing stays as foundation, to the part selection again of easily repairing, as implant part, implants;
2) original gear axial wood matter is determined, can directly be determined that the material of the identical material of direct selection of material is as implant part, for can not determine material, by chemical analysis, select to study minute approaching material as implant part with original gear axiation;
3) material of implant part is carried out to roughing and heat treatment according to specification requirement, to the coupling part of foundation and implant part, adopt Tenon to be connected simultaneously, and tenon and mortise are carried out to roughing, it is the bluff body that circular arc, middle part are parallel lines that described tenon is two ends, requirement of strength to implant part is calculated, and determines length L and the thickness H of described tenon;
4) tenon and mortise are carried out to fine finishining, tolerance fit adopts interference fit, and assembling adopts hot charging to join;
5) after joinery and its construction has assembled, by original gear shaft specification requirement, implant part is carried out to fine finishining, meet technical parameter requirement.
In step 3), for the requirement of strength of implant part, by following data, calculated: the power (Kw) that 1. axle transmits; 2. the rotating speed of axle (r/min); 3. the diameter of axle (mm); 4. allowable stress (the N/mm of axle
2); 5. the moment of torsion (N.M) that axle transmits, by calculating and the check of above-mentioned parameter, determines many group L and H value, by method of comparison, selects best L and H value to implant.
Adopt technique scheme, obtained beneficial effect is:
The present invention passes through the above-mentioned problems in the prior art, by rational process, carry out the selection of the material of gear shaft, the shape of syndeton and the calculating of parameters of structural dimension, it is had repairs fast, stable work in work after implanting, long service life, and it is low to implant cost, and the production line moving for the restorer of being eager has special effect.
