Description
【発明の詳細な説明】 （イ）発明の技術分野 本発明は、補則した管状プロペラシャフトに関する。[Detailed description of the invention] (b) Technical field of the invention The present invention relates to a supplemented tubular propeller shaft.

ければならない。(0) Background of the Technology The use of tubular propeller shafts to transfer torsional moments between a power generating device and some type of utilization device is known, but their torsional resistance is limited by their relatively small cross-sections. However, provision must still be made for the transmission of relatively high torques.
（ハ）従来技術と問題点
これまで、たとえば自動車等に用いられて来たプロペラ

して臨界振動を受けないよう保証する太さとしていた。(C) Prior art and problems The cross-sectional dimensions of propeller shafts that have been used in automobiles and the like have increased in proportion to the size of the power generator and the length of the built-in drive span. At all times, the thickness was chosen to ensure that the shaft was never subject to critical vibrations under all working conditions.

りシャフトが−乃至複数の点で穿孔されていても尚、か
けられたねじりモーメントを伝達出来ねばならない場合
、プロペラシャフトの断面は、さらに一層太（される。Furthermore, if the shaft is operated under external stress, such as the impact of a perforation on the body, it will still transmit the applied torsional moment even if the shaft is perforated at - or at several points. If it must be possible, the cross-section of the propeller shaft will be made even thicker.
従って、節単に言えば、公知の型のプロペラシャフトは
、伝達すべきトルクと、駆動スパンの長さと、シャフト
が衝撃にさらされる程度に比例して太くなっている。Thus, in simple terms, propeller shafts of known types are thicker in proportion to the torque to be transmitted, the length of the drive span, and the extent to which the shaft is exposed to shocks.

想定すれば、シャフトの重さは明らかに解決の難しい問
題である。The weight of the drive is not usually a critical issue in ground vehicles, but it is of critical importance in aircraft.For example, if the tail rotor on a standard helicopter were to overwhelm the propeller shaft. It is connected to the power equipment through the propeller shaft, and not only is the propeller shaft not very long,
The weight of the shaft is obviously a difficult problem to solve, given that it is normally exposed to external forces over a portion of its length.
この解決は、軍用ヘリコプタ−の場合、一層重要なもの

穿孔に会っても、破壊に耐え、その厚みは亀裂の伝播を
出来る限り遅らすことの出来るものでなくてはならない
。This solution becomes even more important in the case of military helicopters, where the propeller shaft cross-section is such that it can withstand a perforation of approximately 2 cal and is thick enough to slow crack propagation as much as possible. Must-have.

As far as vibration is concerned, even though it is in a critical or supercritical state, the payload remains unchanged due to excessive weight.
This has a negative effect on the effective payload.

本発明の目的は、比較的軽量、小断面で、しかもねじれ
抵抗が比較的高く、亀裂伝播が低く、且つ破壊に耐える

とにある。2) Purpose of the Invention The purpose of the present invention is to provide a propeller shaft that is relatively lightweight, has a small cross section, has relatively high torsion resistance, low crack propagation, and has puncture resistance that is resistant to fracture. be.

It includes a core having an integral reticulated covering extending into contact with its outer surface, and said reticulated covering is made of a lightweight composite material.
（−）発明の実施例 次に、本発明の実施例を添付図面を参照して説明する。(-) Examples of the invention Next, embodiments of the present invention will be described with reference to the accompanying drawings.

This shaft is ideally suited for aircraft, especially helicopters, but can equally be used to transfer drive torque between any type of drive and utilization equipment.

れているが、この他の巻き方も可能である。The shaft l includes a tubular core 2 made of metal or synthetic material, and at least two filaments 4, 5 made of lightweight synthetic material crisscrossing each other to form a plurality of links 6. There is. In the illustrated example, the filaments 4 and 5 are wound around the core 2 in opposite cylindrical spirals, but other windings are also possible.

ア２と共に炉処理することで網状カバー３のコア２上へ
の密着が確実となる適当な合成樹脂の中に浸して作る。The filaments 4 and 5 are preferably Kevlar or graphite wires wrapped around the outer surface 7 of the core 2 and treated in a furnace together with the core 2 to ensure close contact of the mesh cover 3 onto the core 2. It is made by soaking it in a suitable synthetic resin.
網状カバー３を構成する合成材料のねしれ−曲げ抵抗に
よりシャフト１のねしれ−曲げ抵抗は大幅に増大する一
方、重量の増加はほんのわずかにすぎない。The torsion-bending resistance of the synthetic material constituting the mesh cover 3 significantly increases the torsion-bending resistance of the shaft 1, while the weight increases only slightly.
こうして網状カバー３は、ねじれ−曲げ抵抗が極めて高
く且つ比較的小径のシャフトを作ることを可能とする。The mesh cover 3 thus makes it possible to create a shaft with very high torsion-bending resistance and a relatively small diameter.

を除去する応力搬送帯としても作用するのである。Additionally, each link 6 has a "break cell" that prevents a break or perforation in the core 2 from extending beyond its limits.
In fact, the striations 4 and 5 not only resist physical crack propagation, but also prevent dangerous loads from concentrating within the braking area, thus eliminating the root cause of crack propagation. It also acts as a stress transport zone for removal.

It is possible to manufacture shirts 1 to 1 with a relatively small diameter, and has advantages such as low crack propagation.
