Embodiment 1

[0039] See attached Figure 1-8 , with Figure 19 .

[0040] This embodiment is applicable to the situation that the end face of the hub of the aircraft wheel does not protrude from the end face of the rim, which includes the end face of the hub being flush with the end face of the rim and the end face of the hub being recessed into the end face of the rim.

[0041] The technical scheme adopted in the present invention is: a kind of wheel rim sheath for aviation wheel, it is characterized in that:

[0042] The rim sheath is a semi-circular piece made of elastic material, the outer end surface and the inner end surface of the semi-circular piece are parallel to each other, and the outer circular surface of the semi-circular piece is a stepped cylindrical surface to reduce the pressure of the rim sheath. the structural weight. The inner circular surface of the rim sheath is divided into an inner cylindrical surface and an inner conical surface. The inner diameter of the inne...

Embodiment 2

[0054] See attached Figure 9-12 .

[0055] This embodiment is applicable to the case where the end surface of the hub of the aircraft wheel protrudes from the end surface of the rim.

[0056] The difference from Embodiment 1 is that the outer side of the groove is a stepped surface, so that the notch of the groove is widened to accommodate the protrusion on the end surface of the hub.

[0057] The technical scheme adopted in the present invention is: a kind of wheel rim sheath for aviation wheel, it is characterized in that:

[0058] The rim sheath is a semi-circular piece made of elastic material, the outer end surface and the inner end surface of the semi-circular piece are parallel to each other, and the outer circular surface of the semi-circular piece is a stepped cylindrical surface to reduce the pressure of the rim sheath. the structural weight. The inner circular surface of the rim sheath is divided into an inner cylindrical surface and an inner conical surface. T...

Embodiment 3

[0063] See attached Figure 13-18 .

[0064] This embodiment is applicable to the case where the end surface of the hub of the aircraft wheel protrudes from the end surface of the rim. The rim includes a fixed rim and a movable rim.

[0065] The difference from Embodiment 1 is that the width of the groove is widened to accommodate the protrusion on the end face of the hub; the inner diameter of the outer end of the semi-circular member is reduced so that the outer side of the groove is in close contact with the end face of the hub protruding from the rim. combine.

[0066] The technical scheme adopted in the present invention is: a kind of wheel rim sheath for aviation wheel, it is characterized in that:

[0067] The rim sheath is a semicircular piece made of elastic material. The outer end surface and the inner end surface of the rim sheath are parallel to each other. The outer circular surface of the rim sheath is a stepped cylindrical surface to reduce the rim The struc...

Abstract

The invention relates to a wheel rim sheath for an aircraft wheel. The wheel rim sheath is a semicircular ring, and the outer end surface and the inner end surface of the wheel rim sheath are parallelto each other. The inner surface of the wheel rim sheath is provided with a wheel rim guard groove, after a wheel rim is clamped into the wheel rim guard groove, the maximum outer surface of the wheel rim and / or the end surface of a wheel hub is attached to the inner surface of the wheel rim guard groove. Wheel rim sheathes are used to clamp wheel rims of the two side surfaces of the aircraft wheel, two wheel rim sheaths on each side surface form a full-circle sheath, so that possible bumping injuries on the outer surfaces of the wheel rims is avoided, in particular bumping injuries at the junction R between the root of each wheel rim and corresponding hub profile is prevented, the problem of bumping injuries easily occurred in assembly and transfer of the aircraft wheel is effectively solved, the high stress area at the root of the wheel rims of the aircraft wheel has good structural integrity, the aircraft can be delivered without bumping injuries, good product quality consistency is realized, hidden danger of fatigue cracks is avoided, and the service life and the use safety are ensured.

Description

technical field [0001] The invention relates to the protection technology of an aircraft wheel, in particular to a rim sheath for an aircraft wheel. Background technique [0002] The aviation wheel is an important load-bearing part of the landing gear of the aircraft, which is installed on the axle at the bottom of the pillar of the landing gear of the aircraft, and is used for taking off, landing, sliding, braking and supporting the aircraft. Aircraft wheels are usually made of light alloy materials such as aluminum and magnesium alloys. When they collide with each other or hit hard objects or sharp objects, they are easy to be bumped and injured, and the rim is at the outer end. If you do not pay attention to the operation, you will be injured, crushed, and deformed first. . There are many processes in the production process of aircraft wheels, and wheel bumps and damages occur from time to time during transshipment and assembly. This not only affects the appearance of t...
