Description
Technical field
The present invention relates to machining technology field, specifically a kind of Aerial weapon equipment bearing extractor and its method of work.
Background technology
Bearing is indispensable part in machine driving, precision between installation process requirement and its axle coordinated is higher, generally it is interference fitted, play is not produced in the course of the work to reach, influence reliability of operation, especially in aviation field, the required precision installed to it is higher, such as helicopter turbine engine bearing, as shown in Figure 1, the Aerial weapon equipment includes integrally formed gear 3 and gear rotary shaft 5 with bearing, bearing is set in by bearing inner ring 4 in the gear rotary shaft 5 of the both sides of gear 3, and one side gear rotary shaft 5 outside be provided with boss 7；In order to meet use requirement, when mounted, usually expand internal diameter using the method for heating bearing inner ring 4, then bearing is assembled in gear rotary shaft 5 by forcing press；Because the outer diameter of bearing inner ring 4 is more than the diameter of its gear rotary shaft 5, when gear rotary shaft 5 is interference fitted with bearing inner ring 4, groove 6 is formed between bearing inner ring 4 and gear 3.But in dismounting, due to that individually can not be heated bearing inner ring 4, simultaneously because structure limitation and bearing are different from the thermal expansion amount of gear rotary shaft 5, therefore can not be dismantled by heating the method for bearing.If dismantled using conventional bearings puller, retainer is locked by the equally distributed three-jaw of puller and unloads bearing.But this method for dismounting is easily caused retainer coating, boss and damaged, and bearing puller is frequently used, and there is the wear problem of three-jaw and screw thread, during locking three-jaw equilbrium position it is difficult to ensure that, add the difficulty of bearing removal.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of simple in construction, Aerial weapon equipment bearing extractor for avoiding part from damaging and its method of work.
In order to solve the above problems, the invention provides a kind of Aerial weapon equipment bearing extractor, the Aerial weapon equipment includes the base in round table-like setting with bearing extractor, two symmetrically arranged support bases, the support base includes side wall and roof, the roof is set in semi-circular and perpendicular to the side wall, two support bases cooperate, its side wall constitutes cylindric supporting part, semi-circular roof has round-meshed Access Division in the middle of constituting, the bearing inner ring outer diameter of Aerial weapon equipment bearing is more than the diameter of its gear rotary shaft, when gear rotary shaft is interference fitted with bearing inner ring, groove is formed between bearing inner ring and gear, the thickness of the roof is adapted with the width of the groove；The Access Division is in the groove between gear and bearing inner ring when using, and bearing to be removed is in the outside of Access Division, and gear is in cylindric supporting part；The distance of the roof lateral surface to base medial surface is adapted with the Aerial weapon equipment with the axial height of bearing, during so that the bearing on the outside of roof leaving gear rotary shaft completely, the Aerial weapon equipment is moved to base position with bearing, prevents from damaging during bearing removal.
Further, the base is provided with ring-type limiting table, and cylindrical shape supporting part prevents two support bases deviations in ring-type limiting table after two support bases cooperate.
Further, the gap between the inwall and gear of the cylindric supporting part that the support base is constituted is no more than 1mm, prevents that gear is rocked in cylindric supporting part during dismounting, gear surface of damaging.
Further, the base center is provided with the receiving hole run through, and the end for accepting gear rotary shaft prevents rotary teeth wheel shaft from damaging.
Further, the diameter of the receiving hole is adapted with Aerial weapon equipment with the boss diameter of bearing, and boss is protected when being dismantled, and prevents from damaging.
Further, the support base using aluminium bar is cleaved, Vehicle Processing and Milling Machining be integrally formed obtained, extracting tool uses making of pure aluminum, and hardness is low, effectively prevents Aerial weapon equipment to be bruised with bearing.
The method of work of above-mentioned Aerial weapon equipment bearing extractor, comprises the following steps：
A, round table-like base is horizontally disposed with, one of support base sidewalls vertical is arranged in the annular stop platform of base, and the roof of the support base is parallel to the base table top.
B, the semi-circular roof by Aerial weapon equipment to be removed with the groove between the gear and bearing inner ring of bearing along support base carry out clamping；The semi-circular roof of another support base is also seeded into the groove between gear and bearing inner ring, the roof of two support bases has round-meshed Access Division in the middle of constituting, so that the gear of Aerial weapon equipment bearing is in the cylindric supporting part below Access Division, bearing inner ring to be removed is in above Access Division.
C, the external forcing press of startup axially apply pressure to the gear rotary shaft of Aerial weapon equipment bearing along it, make gear axial rotary base direction displacement, and bearing inner ring progressively disengages gear rotary shaft in the presence of Access Division, completes the dismounting of the bearing of one end.
Further, the base is vacantly set, and through liftable adapting table is set in the receiving hole of the base, before gear axial rotary base direction displacement, adapting table is supported to Aerial weapon equipment with bearing, is easily installed the semi-circular roof of support base；During gear axial rotary base direction displacement, adapting table synchronous shift prevents Aerial weapon equipment bearing from coming off suddenly, causes damage.
The technique effect of invention：（1）The Aerial weapon equipment bearing extractor of the present invention, relative to prior art, has round-meshed Access Division using centre, bearing to be removed is in the outside of Access Division, and gear is in cylindric supporting part, can easily realize bearing removal；（2）Through liftable adapting table is set in the receiving hole of base, it is easily installed, while can prevent boss from damaging；（3）Base is provided with ring-type limiting table, prevents support base from deviateing；（4）Support base uses making of pure aluminum, and hardness is low, effectively prevents from damaging.
