A kind of aircraft wheel inner oil deflecting ring and its oil deflecting ring assembly

Abstract

The invention discloses an aircraft wheel inner oil deflector ring and an oil deflector ring assembly thereof. The inner oil deflector ring includes a metal frame ring, a dynamic seal ring and a static seal ring, and the dynamic seal ring is detachably arranged on the metal frame ring. On the outer diameter side of the wheel, the static sealing ring is detachably arranged on the outer end surface of the metal skeleton ring; the dynamic sealing ring is dynamically sealed with the inner diameter side of the wheel, and the static sealing ring is connected with the inner ring static seal; the oil deflector ring assembly includes an inner oil deflector ring and an outer oil deflector ring, and the inner oil deflector ring and the outer oil deflector ring are respectively arranged on the inner side and the outer side of the tapered roller bearing; The skeleton ring is detachably provided with a dynamic seal ring and a static seal ring, the dynamic seal with the inner diameter side of the wheel is realized through the dynamic seal ring, the static seal with the inner ring of the tapered roller bearing is realized through the static seal ring, the static seal ring and the The dynamic sealing ring can adopt different structures or materials to achieve better sealing effect.

Description

technical field [0001] The invention relates to the field of aircraft wheels, in particular to an inner oil deflector ring of an aircraft wheel and an oil deflector assembly thereof. Background technique [0002] A tapered roller bearing is arranged between the aircraft wheel and the landing gear shaft, and the relative rotation of the two is realized through the tapered roller bearing. Tapered roller bearings can be divided into outer ring and inner ring. Rollers and cages are arranged between the outer ring and inner ring. Generally, the inner ring, rollers and cage are integrated, which is convenient for installation and disassembly. The outer ring passes through the Ying fit is installed in the wheel bearing hole, and the inner ring is installed on the landing gear shaft, that is to say, when rotating, the outer ring and the wheel rotate, while the inner ring and the landing gear shaft do not rotate. [0003] When tapered roller bearings are used, a large amount of grea...

Problems solved by technology

[0004] The Chinese patent application publication number CN 102966672 A discloses an oil slinger assembly for an aircraft wheel. The inner slinger is located at one end of the wheel hub bearing, and the inner slinger is embedded in a groove on the inner wall of the wheel hub. Realize the fixing of the inner oil deflector ring along the axial and circumferential directions of the aircraft wheel, and prevent the lubricating grease in the hub bearing from flowing out through the inner oil deflector ring. However, the inner oil deflector ring in this scheme does not distinguish between the static seal structure and the dynamic seal structure , there is no targeted setting of dynamic seal and static seal, and the sealing effect is not good
