Abstract
The present invention relates to a kind of restorative procedures of helicopter shaft bearing looseness fault, repairing standard is worn by providing bearing's looseness, and the curing methods such as room temperature are taken, and repair to the paint layer destroyed in bearing repair process, make the tailing axle after repairing that can continue to come into operation.The present invention in certain type helicopter shaft bearing looseness fault using for many years, it is repaired after shaft bearing it is good in outfield working condition, not feedback bearing's looseness problem.
Description
Technical field
The present invention relates to repairing for a kind of restorative procedure of bearing's looseness, especially a kind of helicopter tail transmission shaft bearing's looseness
Compound method.
Background technique
Bearing is installed, bearing inner ring and shaft tube cooperate, and outer race and vibration isolation rubber serve as a contrast on helicopter tailing axle
Set cooperation, to eliminate vibration when tailing axle work.Tailing axle both ends are flange plate structure, and ring flange largest contours outer diameter is greater than bearing
Inner ring, therefore, tailing axle need to first install bearing, rear mounting flange when installing.Meanwhile tailing axle is made of multistage aluminum pipe, and aluminium
It is connected by way of riveting between pipe, therefore the bearing on tailing axle is non-dismountable.Because being influenced by operating condition, tailing axle work starting
When, it will appear bearing's looseness situation often.After bearing's looseness, if repairing not in time, it will cause the biggish vibration of tailing axle, and add
Fast tailing axle abrasion, will affect complete machine safety when serious.Since the bearing on tailing axle is non-dismountable, and there is no feasible reparation early period
Method is forced to scrap a whole set of tailing axle when shaft bearing loosens, and causes very big waste.
Summary of the invention
The purpose of the present invention is to provide a kind of restorative procedures of helicopter shaft bearing looseness fault, by providing bearing
The reparation step and means of defence of loosening guarantee that tailing axle can continue normal use, reduce waste.
The technical scheme is that：The restorative procedure of helicopter tail transmission shaft bearing's looseness includes the following steps：
(1) confirm bearing loosening mode, if bearing can not axial motion, repaired by (2) step, otherwise reported
It is useless；
(2) paint layer that tailing axle upper bearing (metal) removes end is removed with paint remover, bearing is removed, carefully clear up bearing installation
Position performs the next step rapid after cleaning；
(3) diameter of axle of bearing inner ring matching part is measured, if the diameter of axle is not less than limit of wear size Then
It is repaired by (4) step, is otherwise scrapped；
(4) acetone bearing cleaning installation site and bearing inner ring are used, guarantees its cleaning positions free from admixture；
(5) installing positions of bearings on tailing axle applies loctite638 glue, guarantees that glue is uniformly distributed；
(6) bearing is debugged to original-assemblied machine position, and applies loctite638 glue in bearing one end, between glue infiltration infiltration
In gap, solidify 30 minutes at 25 DEG C ± 5 DEG C of room temperature condition；
(7) tailing axle after normal temperature cure is taken out, is put into insulating box, it is small to solidify 24 within the scope of 35 DEG C ± 5 DEG C of temperature
When；
(8) tailing axle is taken out from insulating box, to 1 layer of bottom of tailing axle coating removal position coating at 25 DEG C ± 5 DEG C of room temperature condition
H06-25 is painted, and is solidified 3~5 hours, guarantees that paint layer does not reveal matrix continuously；
(9) 1 layer of priming paint H06-26 is applied again, and is solidified 3~5 hours at 25 DEG C ± 5 DEG C of room temperature condition, guarantees that paint layer is continuous；
(10) 1 level paint H04-2 is applied again, and 25 DEG C ± 5 DEG C of room temperature condition solidify 3~5 hours, guarantee that paint layer is continuous；
(11) repairing terminates, and submits and examines.
In described (6) step, torsion is applied to bearing, changes gap constantly, guarantees the effect of impregnation of glue.
The present invention loosens type by confirmation shaft bearing, and provides bearing's looseness abrasion repairing standard, by bearing
One end uniformly applies loctite638 glue, and takes the curing methods such as room temperature, ensure that the cementability of glue.Bearing was repaired
The paint layer destroyed in journey is repaired, and ensure that the adaptive capacity to environment on tailing axle surface.When occurring loosening and accord in shaft bearing
When closing repairing standard of the invention, it can continue to come into operation using the tailing axle after the invention reparation.The invention is gone straight up in certain type
In tail axle bearing looseness fault using for many years, it is repaired after shaft bearing it is good in outfield working condition, not in resetting shaft
Hold loosening problem.
