Embodiment Construction

[0025] The structural reference of the embodiment of the device of the present invention figure 1 , including a resolver stator and a resolver rotor, and a magnetic field air gap 10 is formed between the resolver stator and the resolver rotor. The resolver stator includes stator core 3 , stator winding (primary winding) 2 , stator winding stainless steel frame 4 , stator core outlet hole 1 and stator winding lead wire 11 . The resolver rotor includes rotor core 6, rotor winding (secondary winding) 8, rotor winding stainless steel sleeve 5, rotor core inner through hole 7, rotor core outlet hole 9 and rotor winding lead wire 12.

[0026] like figure 1 , the stator winding 2 is tightly wound on the stator winding stainless steel framework 4 and embedded into the stator core 3 . The stator core 3 is a cylindrical structure with inwardly protruding bosses at both axial ends, the purpose of which is to reduce the magnetic field air gap 10 and increase the coupling coefficient bet...

Abstract

The invention discloses a rotary transformer for a real-time monitoring system of an airplane tire pressure. A stator winding stainless steel framework is a hollow cylinder; a stator winding is wound on the outer wall of the stator winding stainless steel framework; a stator iron core is a cylindrical structure coated outside the stator winding stainless steel framework and the stator winding; lug bosses are respectively formed at axial two ends of the stator iron core; a rotor iron core has a hollow cylindrical structure; a rotor winding is wound on the outer wall of the rotor iron core; lug bosses are respectively formed at axial two ends of the rotor iron core; a rotor winding stainless steel sleeve is coated on the outer sides of the rotor winding and the rotor iron core; a rotor winding stainless steel sleeve is nested in the stator winding stainless steel framework; and the rotor winding stainless steel sleeve is not contacted with the stator winding stainless steel framework. The rotary transformer can be processed into any shape as required and has the advantages of easy processing, easy installation, capacity of reducing size and weight, breaking-free property, high reliability and capacity of ensuring conformity of electrical character.

Description

technical field [0001] The invention relates to a transformer, in particular to a rotary transformer used in an aircraft tire pressure real-time monitoring system. Background technique [0002] Aircraft tire pressure real-time monitoring system is a kind of monitoring the air pressure inside the tire, providing the actual pressure of the tire to the crew or maintenance personnel through the data bus and display, and can give an alarm to the abnormal tire pressure, and can adjust the tire pressure according to the driver's instruction. It is a device for regulating the pressure of aircraft tires, which is a new technology to ensure the safety of aircraft. In daily maintenance, the system can also eliminate the manual measurement of tire pressure on the ground, reducing the workload of tire maintenance. [0003] In the aircraft tire pressure real-time monitoring system, the in-wheel monitoring module is located on the wheel and rotates with the wheel at a high speed. Its powe...
