Abstract
The invention belongs to helicopter design fields, and in particular to a kind of collecting ring chocking construction.For the fixed part of collecting ring, stopping effect and persistence are often not satisfactory the prior art.The present invention provides a kind of collecting ring chocking construction, prevent the conducting ring assemblies of collecting ring from rotating with Helicopter Main blade, in vertical tube on the sleeve insertion helicopter hanger disk of the collecting ring, the chocking construction has been arranged radially backing pin on sleeve, L-shaped groove is provided on the tube wall of vertical tube, after the shelves pin enters axially into the L-shaped groove, in blade rotation, the sleeve is by circumferential stop.Using collecting ring chocking construction of the invention, the conducting ring assemblies of collecting ring can be effectively prevent to rotate with Helicopter Main blade under the premise of not increasing volume.The present invention, which breaks the prior art, has thinking in the used of the field, plays excellent results beyond expection.
Description
Technical field
The invention belongs to helicopter design fields, and in particular to a kind of collecting ring chocking construction.
Background technique
To meet requirement of the helicopter under natural freezing environment, electric heating rotor need to be installed additional and prevent/deicing system, collection
Stream ring realizes the transmission of the power supply and signal from fixed position to rotation position, and chocking construction is to realize above-mentioned rotary transfer
Pith.For the fixed part of collecting ring, stopping effect and persistence are often not satisfactory the prior art.
Summary of the invention
The object of the present invention is to provide a kind of collecting ring chocking constructions, prevent the conducting ring assemblies of collecting ring with helicopter
Main blade rotates together, passes through the transmission of power supply and signal on the rotation realization machine of conducting ring assemblies and brush assembly of electric.
The technical scheme is that a kind of collecting ring chocking construction, the sleeve of the collecting ring is inserted into helicopter hanger
In vertical tube on disk, which has been arranged radially backing pin on sleeve, is provided with L-shaped groove on the tube wall of vertical tube, works as institute
It states after shelves pin enters axially into the L-shaped groove, in blade rotation, the sleeve is by circumferential stop.
The backing pin and sleeve connect in such a way that threaded connection and flaring riveting are combined.
The L-shaped groove has certain longitudinal depth, overcomes the assembly problem as caused by manufacturing tolerance.
When disk is hung in disassembly, vertical tube is limited by the backing pin on sleeve.
The invention has the advantages that backing pin is stuck in the L-shaped groove of riser upper end using collecting ring chocking construction of the invention,
It plays the role of stopper, the conducting ring assemblies of collecting ring can be effectively prevent with Helicopter Main blade under the premise of not increasing volume
It rotates together.The present invention, which breaks the prior art, has thinking in the used of the field, plays excellent results beyond expection.
Detailed description of the invention
Fig. 1 is the assembling schematic diagram of collecting ring chocking construction of the present invention；
Fig. 2 is the chocking construction enlarged drawing of Fig. 1；
Fig. 3 is the L-shaped groove schematic diagram on vertical tube.
Specific embodiment
The present invention is described in further details below.
With reference to FIG. 1 to FIG. 3.The sleeve 3 of collecting ring 4 is inserted into the vertical tube 1 on helicopter hanger disk, which is covering
It has been arranged radially backing pin 2 on cylinder 3, L-shaped groove is provided on the tube wall of vertical tube 1, after the shelves pin 2 enters axially into the L-shaped groove,
When blade rotation, the sleeve 3 of collecting ring 4 is by circumferential stop.
The backing pin 2 and sleeve 3 connect in such a way that threaded connection and flaring riveting are combined, and play the role of stopper, prevent
The conducting ring assemblies of collecting ring are rotated with Helicopter Main blade.
When work, conducting ring assemblies keep opposing stationary, brush assembly of electric with main reducing gear central axis by backing pin and vertical tube
It is fixed in rectification cover support members with outer cover etc. and is rotated with Helicopter Main blade.Pass through conducting ring assemblies and brush assembly of electric
Rotation realization machine on power supply and signal transmission.
