Technical field

The invention belongs to helicopter landing gear system regions, are related to a kind of structure for improving tail-wheel lock maintainability.

Background technique

Currently, volume shipment is in helicopter landing gear system for tail-wheel lock, to product reliability, maintainability, protection It is required that being continuously improved, existing product structure cannot fully meet user demand, and user controllably destroys unit more to product outfield It changes process and replacing construction complaint is very big, it is desirable that my company optimizes product.Actually used, installed according to product, Situation is dismantled, design is improved to product structure, improves Product maintenance, shortens maintenance time, simplifies maintenance process.

Summary of the invention

Goal of the invention

To solve the above problems, the present invention provides a kind of structure for improving tail-wheel lock maintainability, by that will be locked in structure Bar be designed to can two bodies that quickly split of outfield, avoid only replacing on machine and controllable destroy unit locking bar, spring washer and gag lever post The complicated processes that Shi Yaoxian removes a whole set of products from undercarriage substantially reduce the Flight Line Maintenance time, simplify and repaired Journey.

Inventive technique solution

In order to achieve the above-mentioned object of the invention, the present invention uses following technical solutions:

A kind of structure improving tail-wheel lock maintainability, controllable destruction unit locking bar and gag lever post are detachably connected.

Preferably, it controllably destroys unit locking bar and gag lever post is connected through a screw thread.

Preferably, it controllably destroys unit locking bar lower end and external screw thread is set, internal screw thread is arranged in gag lever post upper end.

Preferably, it is locking using spring washer that unit locking bar and gag lever post junction are controllably destroyed.

Preferably, gag lever post connect one end outer mold surface with the controllable unit locking bar that destroys as outer six side.

Preferably, gag lever post offers interior six square grooves far from controllable unit locking bar one end end face of destroying.

Advantages of the present invention

The present invention has the advantages that

By by locking bar be designed to can two bodies that quickly split of outfield, avoid only replacing on machine it is controllable destroy unit locking bar, When spring washer and gag lever post, the complicated processes first to remove a whole set of products from undercarriage improve Product maintenance.

Specific embodiment

In conjunction with summary of the invention general introduction and attached drawing, the specific embodiment that the present invention will be described in detail.

As shown in Figure 2, Figure 3, Figure 4, a kind of structure improving tail-wheel lock maintainability, it is controllable to destroy unit locking bar 3 and limit Bar 5 is detachably connected.Controllable destruction unit locking bar 3 and gag lever post 5 are connected through a screw thread.Controllable 3 lower end of unit locking bar of destroying is set External screw thread 41 is set, internal screw thread 53 is arranged in 5 upper end of gag lever post.Controllable unit locking bar 3 and 5 junction of gag lever post destroyed is using spring pad It is locking to enclose 4.Gag lever post 5 connect one end outer mold surface with the controllable unit locking bar 3 that destroys as outer six side 51.Gag lever post 5 is far from controllable broken 3 one end end face of bad element locking bar offers 52 slot of interior six side.

By by locking bar be designed to can two bodies that quickly split of outfield, avoid only replacing on machine it is controllable destroy unit locking bar 3, When spring washer 4 and gag lever post 5, the complicated processes first to remove a whole set of products from undercarriage improve Product maintenance.

Disassembly: it first moves toward straightening the split pin (2) on installation stud 1 and is taken out out of hole, back out nut (2), will install Stud 1 (2) is backed out from undercarriage rocker arm 2 and (is coated with thread locking agent on screw thread), and locking bar is taken out out of undercarriage rocker arm hole Out, tail-wheel lock is removed.

Replacement: it first moves toward straightening the split pin (1) on pin shaft and is taken out out of hole, pin shaft is extracted out out of lock body opening, is removed Locking bar 3 more renews locking bar, spring washer 4 and gag lever post 5, is fixed on lock body with pin shaft, and construction opening pin is locking.

Installation: first tail-wheel lock locking bar 3 is put into 2 hole of undercarriage rocker arm, two groups of mounting holes of tail-wheel lock are shaken with undercarriage The alignment of 2 hole of arm applies thread locking agent on installation stud 1 (2) inside thread and has been screwed into across two groups of mounting holes of tail-wheel lock It falls in frame threaded hole (2 groups), adjustment installation stud (2) extension elongation meets installation requirement, nut (2) is screwed on, with opening Pin (2) is locking, and adjustment 3 lower part extension elongation of locking bar meets installation requirement, is powered and checks unlocking and lock, checks unlock manually And locking, it should all be qualified.
