Embodiment Construction

[0016] After a long period of trial and error, the final manufacturing steps of the shielding layer are determined as follows:

[0017] 1. Apply the first layer of epoxy glue. Clean the surface of the rotor with a mixture of alcohol and ether, apply epoxy resin glue on the winding copper skin, and then place the rotor coated with epoxy resin glue in the vacuum box. The coating position of the adhesive layer should be: from the inner ring to the outer ring of the winding copper skin, to protect the radial metal mounting surface, outer cylindrical surface and inner hole mounting surface of the circular induction synchronizer rotor.

[0018] 2. Epoxy resin glue curing. Let the adhesive layer cure at room temperature for ≥48 hours.

[0019] 3. Grind the epoxy resin adhesive layer. After the glue dries, smooth the epoxy adhesive layer on a grinding machine. The thickness of the grinding adhesive layer is controlled at 0.02-0.04mm.

[0020] 4. Apply the second layer of epoxy resi...

Abstract

The invention discloses a vacuum coating based round inductosyn shielding layer structure. A stator and a rotor of the round inductosyn both consist of a substrate, an insulating layer and a winding. In order to shield electromagnetic interference and improve angle measuring accuracy, the shielding layer is plated on the rotor surface. The traditional structure of the shielding layer is an aluminum foil shielding layer, which bubbles under a thermal vacuum environment, thus causing contact of the stator and rotor windings so as to result in a short circuit. By composing the shielding layer with an epoxy resin layer and a vacuum coating layer, the invention can solve the defect of bubbling of the shielding layer under a thermal vacuum environment, and has high reliability.

Description

technical field [0001] The patent of the present invention relates to a shielding layer structure of a circular induction synchronizer, in particular to a shielding layer structure of a vacuum coating-based circular induction synchronizer used in an aerospace environment. Background technique [0002] Inductosynchronizer is a kind of angular displacement sensor, which is a kind of multi-pole sensing element. Since the multi-pole structure compensates for errors, the element has high precision. Inductive synchronizers are divided into two types: rotary and linear, according to their different motion modes. The former is used to detect the rotation angle, and the latter is used to detect the linear displacement. Its structure includes both fixed and moving parts. For the rotary type, they are called the stator and the rotor respectively; for the linear type, they are called the fixed length and the slide rule respectively. [0003] The induction synchronizer has the advanta...
