Abstract
The invention relates to a method for repairing spline abrasion.By means of cost analyzing, measuring and calculating, parts with large cost are preferably kept, parts with small cost are prepared, fewer parts can be machined, and periods and cost are saved.By means of the method, the abraded part scrappage of a mechanical device can be effectively reduced during repairing, and manpower, material resources and cost can be saved.
Description
Technical field
The present invention relates to a kind of repair method, the repair method of especially a kind of spline wear, it is possible to achieve shorten the repair cycle, save the purpose of cost.
Background technology
In many machinerys, spline is a kind of conventional drive mechanism, is generally used to position the transmission with moment of torsion.Prolongation along with the working time, owing to spline bears moment of torsion, spline is inevitably made to wear and tear, the fit clearance between spline is caused to increase, make it position to increase with transmission accuracy decline, vibration, thus causing that whole machinery service behaviour declines, directly resulting in machinery time serious cannot normal operation.After abrasion occurs in spline, for avoiding the service behaviour of machinery to reduce, generally require the part rejection beyond the limit of wear and replace with new product part.Often be designed to one with drive disk assembly due to spline, processing needs waste substantial amounts of artificial and cost again, causes the high cost repaired and overhaul.For being worth bigger part, this impact is especially apparent.
Summary of the invention
It is an object of the invention to provide the repair method of a kind of spline wear, it is possible to reduce scrapping of part, save human and material resources and cost.
Repair method of the present invention comprises the following steps:
1, the spline pair that will appear from abrasion decomposes；
2, analyze two cost of parts that interior external splines is set, and choose the part that cost is bigger, measure the actual transverse tooth thickness after the abrasion of its spline；
3, according to the transverse tooth thickness value after measuring, calculating whether this spline can meet the intensity index of mechanical movement, if meeting, then the measured data according to this spline, manufacturing the part at the spline place being mated；If being unsatisfactory for, then by this part rejection, and measure the actual transverse tooth thickness after the abrasion of another spline；
4, according to the transverse tooth thickness value after measuring, calculating whether this spline can meet the intensity index of mechanical movement, if meeting, then the measured data according to this spline, manufacturing the part at the spline place being mated；If being unsatisfactory for, then by this part rejection.
In Machine Design, the strength margin of spline is general all relatively larger, so after a small amount of thickness of spline wear, its residual intensity likely can also meet requirement, so only need to ensure the theoretical fit clearance of matching spline, it is possible to ensure that part continues trouble free service.Repair method provided by the invention, pass through analysis cost, measure and calculate, the part that preferred retained costs are big, manufacture the part that cost is little, one part of few processing can be realized, saving cycle and cost, simultaneously, if the part that cost is big is unavailable, the part that then retained costs are low, manufacture the part that cost is big, time and cost can also be saved, simultaneously, it is based on the spline after abrasion, namely the spline that transverse tooth thickness is thinning manufactures, for ensureing fit clearance requirement, the spline transverse tooth thickness then manufactured can relatively theoretical value be thicker, strength margin is bigger, longer service life.Therefore, the method for the present invention can effectively reduce the machinery wearing part scrappage when repairing, and saves human and material resources and cost.
Detailed description of the invention
The repair method of a kind of spline wear, comprises the following steps:
1, the spline pair that will appear from abrasion decomposes；
2, analyze two cost of parts that interior external splines is set, and choose the part that cost is bigger, measure the actual transverse tooth thickness after the abrasion of its spline；
3, according to the transverse tooth thickness value after measuring, calculating whether this spline can meet the intensity index of mechanical movement, if meeting, then the measured data according to this spline, manufacturing the part at the spline place being mated；If being unsatisfactory for, then by this part rejection, and measure the actual transverse tooth thickness after the abrasion of another spline；
4, according to the transverse tooth thickness value after measuring, calculating whether this spline can meet the intensity index of mechanical movement, if meeting, then the measured data according to this spline, manufacturing the part at the spline place being mated；If being unsatisfactory for, then by this part rejection.
Embodiment
Certain Helicopter Transmission System left input gear place internal spline, is that by splined shaft, the power of rear input gear is passed to left input gear, by the unified transmission realizing power of left input gear.It is frequently found this internal spline to wear and tear when overhauling, causes that fit clearance is excessive, it is impossible to be continuing with.To concretely comprising the following steps that it places under repair:
1, the spline pair that will appear from abrasion decomposes；
2, two parts that interior external splines is set are analyzed, the i.e. cost of left input gear and splined shaft, wherein the cost of left input gear is relatively big, therefore takes the left input gear that cost is bigger, measure the actual transverse tooth thickness after the abrasion of its internal spline, minimum for 1.9mm (pattern requires 2.4mm)；
3, according to the transverse tooth thickness value after measuring, carrying out Strength co-mputation, result can also meet the intensity index (safety coefficient 2.6, more than require 1) of moment of torsion transmission after showing this spline wear, the then measured data according to this spline, manufactures the splined shaft at the external splines place being mated.
The left input gear worn and torn by internal spline has carried out test run checking in factory after recovering assembling with the splined shaft manufactured, do not occur to vibrate the abnormal conditions such as excessive, this place has carried out overhaul, also no abnormality seen situation after test run in commissioning process.
